internships – re:3D | Life-Sized Affordable 3D Printing

Intern Jacob Lehmann shares on his recent DIY solution to personalize his aging Beetle.

My 3D printed Superman Hood Emblem

By: Jacob Lehmann

I work at re:3D and my job is to figure out and test cool and unique ways to use our 3d printers. I have 2003 VW beetle (and I love it) but some of the aesthetics have been worn and aged poorly over the years. So I had the idea to custom print a rear hood ornament. My amazing bosses thought this was a great idea and helped me to design and realize this idea.

It was hard to pick what exactly I wanted to make for my car. After running through tons of ideas I finally decided that because of the deep sienna blue of my vehicle that a superman logo would look amazing on it. This is a picture of my car after I peeled off the old rusty and broken VW emblem.

Thankfully our friends at Deep in the Heart Art Foundry (who own some of our Gigabots and use them in their lost wax casting) were more than happy to help us cast an alternative. We originally wanted to cast the piece in bronze and patina it, but they suggested that it would look better and be much lighter to cast it in Stainless steel. You can check out some of their amazing works of art here http://www.deepintheheart.net/. Here is the piece once we got it back (with a little bit of polishing).

For a long time, my best friend Mason has been bugging me to watch Rooster Teeth’s animated show RWBY. Don’t get me wrong, I love anime, but I was already watching too many shows, and kept putting it off. Then, one day, re:3D’s cosplay enthusiast Rebecca asked if there was some way we could print the Crescent Rose (the instantly recognizable, 6ft tall scythe from RWBY). I immediately said yes, which made me finally binge-watch volumes 1 and 2 of RWBY on Netflix. Much to Mason’s delight, I loved it! I was super excited to make the scythe, not just because of my inner fangirl, but for the creative challenge of creating a 6 foot tall 3 foot wide scythe!
Rebecca and I debated for many hours about how to go about the design for the scythe. As you all might know, the Crescent Rose has the ability to transform into a more compact gun. We discussed the viability of this option ,and ultimately decided that because of the plastic we would be using and the laws of physics, that we should pursue making the best possible scythe-version of the Crescent Rose, and not worry about it transforming.
So, I threw myself into research. I spent many hours pausing the show and sketching, as well as staring at various other interpretations of the scythe on google images. I finally decided on a plan of action, and started modeling the scythe in Onshape, a beta CAD software.
When using a 3d printer, it’s important to keep in mind how your piece is going to be printed. 3D printers start to print from a base layer up, and use supports for overhanging parts. Therefore, I modeled most of the scythe to be easily printed from a flat bottom. Although I could have modeled the piece completely true to the show, I gave up some minor design features so that my prints would be faster and use as little supports as needed. The Gigabot, because of its large print size of 8 cubic feet, allowed me to make the individual pieces much larger and easily create a life sized model of the scythe.
I made the model into 11 different pieces that could be assembled after they were pulled off the printer. I then printed these pieces using PLA on a Gigabot. I used different infills and layers for different pieces, 2-3 layers depending on how much strength I was going to need from that piece and ranged 5-20% infill depending on if I need the piece to be light or not. I usually heat the plastic at around 195-200 degrees Fahrenheit.
When assembling plastic pieces, together keep in mind in order in which you want to paint your piece, and the different bond strength of the glues or tapes you are using. For the Crescent Rose, I mainly used just basic Gorilla Glue super glue. For more stress intensive pieces, I used Gorilla Glue epoxy and clear caulk to give joints a more uniform look.
Everything was not all roses and sunshine though. I had some large problems throughout the course of making this scythe. Some pieces ended up being more fragile than I would have wanted, and broke a few times. The overall size and shape of the scythe creates its own unique problem. Even though the material is fairly lightweight, the scythe acts as a natural lever where the fulcrum is where the staff meets the blade, causing a large amount of pressure and tension right at the joint. My solution to this problem was more gorilla glue and wooden and metal rods drilled into the plastic and hammered through to help support the weight.
Another huge problem that occurred during the print of one of the pieces completely failed on us. The head of the Gigabot extruder got clogged 48 hours into the 55 hour print. Fortunately, when a print fails, the print usually has a flat layer at the point of failure. I was able to measure the print, and edit my model accordingly so, so I could print only what was missing. The end result looks just like a filament swap mid-print. I credit the ease of this fix to the great usability of OnShape.
Finally, the last and probably worst problem I ran into was the Texas Summer Sun… This is a problem that is unique to people in the south who use 3D printers. Even though the plastic melts at roughly 200 degrees fahrenheit, your print will warp if left in your car or your backyard too long. This happened on the largest piece of the scythe and caused my really nice print fix to be extremely noticeable. I had to reheat my piece and to try and warp it back to a usable condition– with limited success. I decided at the end that the condition of the piece after I re-warped it was good enough to merit not reprinting 55 hours worth of plastic.

Pranathi Peri is developing a set of 3D printed, playable musical instruments for her summer internship. In her own words, she describes her design process:
Have you ever wanted to 3D print your own ukulele? Well now uke can! For the second instrument of my 3D printing internship, I decided to design and print a ukulele. After all, who didn’t trawl the internet looking for the best acoustic guitars under 300, and then end up with a ukele anyway because it was cheaper? They have such a charming aesthetic, and it’s that student living nostalgia that I wanted to try and tap back into. It also dramatically simplifies the process of choosing an acoustic guitar for your child, you can just print one instead now. Although, we have to admit, perhaps it won’t have the same charm.
The history of the good ol’ uke goes way back. During the late 1800s they were first introduced as instruments in Hawaii, where its name literally meant “jumping flea. ” Well-known songs like I’m Yours, by Jason Mraz, Riptide, by Vance Joy, and Imagine, by John Lennon have familiar ukulele riffs which have contributed to the popularization of the instrument, yet these bands use the ukulele in maybe one to two of their songs, and then proceed to abandon it.
I know what you’re thinking; why would I want to design such an uncommonly played instrument?
Although the ukulele is not a widely sought-after instrument like the electric guitar, and piano, I decided to design and print it because it combines the aspects of many popular, commercialized instruments. For example, the ukulele is compact, like the violin, but is not as susceptible to external factors that may may warp the acoustics. It retains the same resonance as the acoustic guitar like the Yamaha FGX800c, but within a smaller body. It has strings that can be tuned, just like a piano, but rather than 236 strings, each with their own unique thickness and reverberation, it has 4 which are tuned to C, E, G, and A . For these reasons, and many more, I figured that a ukulele would be relatively easy to design and print, while still containing key aspects of various other basic instruments.
During the process of actually printing the ukulele, I learned many things about designing the instrument itself. One of which being, SAVE YOUR SOLIDWORKS MODELS EVERY 5 MINUTES. There is nothing more traumatic than losing a solidworks file which you had just finished after 1 solid week of work.
However, the portion of this project in which my learning fared most, was the printing, and post-processing of the instrument. Failed prints were rather frequent in the first stages of printing. During our first attempt at printing the body, we decided to orient the body to stand at a 45 degree angle, in order to print it all in one piece. Little did I know that what would be printed would look something like a bird’s nest. Because of some issues with the fan near hot-end of the bot, the print shifted, and proceeded to print midair. Although printing the body in one piece was possible, we decided to go the easier route of printing it in two separate, flat pieces.
The fretboard took several prints, but I had already expected this when I was designing the ukulele. In order to get the placement, and height of the frets just right, it would require some trial and error. This is why I made the neck and frets separate pieces in my model. The first fretboard I printed was way too thick, causing the strings to collide with the higher-up frets. This ended up producing not-so-pleasant vibrations. The fret placement was also a little bit off, causing all the notes to be disturbingly sharp.
Over-all, printing this ukulele definitely gave me more insight into the musical world. Not only did it open up a new door of opportunity for gigabot, but it also taught me the process of trial and error, and that things rarely ever work out the first time. Another interesting thing I learned about the acoustics of the instrument, was that the PLA filament body actually had a stronger, and more vibrant resonance, as opposed to the wooden ukulele.

Jacob Lehman is exploring 3D printing & cosplay during his summer internship. In his own words, he describes his design process for printing Thor’s Hammer Mjolnir
Are you tired of those pesky frost giants always ruining your day? Well fear no more! With The Thunder God’s Hammer Mjolnir, you will be able to make frost giant toast and butter them to perfection with a few extra bludgeons! Forged in the heart of a dying star or on a 3D printer (I forget which) this Hammer will always be able to tenderize your enemies with shocking ease, but only if you are worthy!
3D modeling in cosplay is great way to create large lightweight and durable props. Because 3D printing can create a shell on the outside and a mesh layer on the inside, the final product ends up being lightweight. This is great for cosplayers that want to carry around weapons that are bigger than their body all day at a convention. This also applies to full bodies of armor. 3D printing can also make higher quality props due to the ability to leverage better in precision of designs and symmetry than hand carvings or paper mache.
The Gigabot, due to its very large bed, is much better suited to printing cosplay props than a regular desktop 3D printer. Larger pieces means that there is less assembly at the end and an overall uniformity to the final model.
When I began the project I decided to make the hammer modular, meaning that it is comprised of multiple pieces that would be assembled at the end. I did this because it allows me to go back and change pieces if I want to and not have to reprint the entire hammer. This is also a good experiment for some of my later projects that will be larger than the 8 cubic feet build volume of the Gigabot. I wanted to practice with different designs as well as different methods of assembly.
My project helps to build upon and intersect with the techniques used by the artistic and inclusive cosplay community. It allows me to document the possibilities of 3D printing and provide alternative methods for creating props and wearables.
I modeled Thor’s Hammer on a Beta CAD software called Onshape. Overall it took me about 8-10 hours to complete the model with various iterations sucking up most of the time. Here are a few of the early models:
Both of these had some obvious flaws that I decided I didn’t like for the final product and I ended up sticking to the Marvel Cinematic Universe Version. The second picture shown above is one of the models where I did a lot of mirroring to save time on making the model and ended up doing a really intricate half of the model. When I mirrored the base it ended up being too long. Here is my final model:
This file was then moved over to another software called Simplify3D where it was formatted for printing. All three pieces were printed on the same print on the Austin Office Gigabot and took about 18 hours to print from start to finish. I decided to print it in PLA because it is a lightweight, sturdy, and relatively cheap material. Here is what it looks like once it is printed with the supports and after I took off the support and assembled it using gorilla glue.

Working with 3D printing. Where to begin?

Konstantin Ivanov, co-founder of 3DPrintus and DigiFabster, mastered 3D printing on his own. He said that studying theory, browsing thematic sites and communicating with domestic and foreign experts helped him in this. However, theory is theory, and practice has not been canceled. Therefore, below we will analyze what to do if you want to work in the 3D industry.

According to Konstantin, at the very beginning of the development of additive technologies, it is important to understand in which particular area you want to become a professional.

3D modeling

3D modeling includes a wide range of tasks that will be of interest to designers, engineers, planners, architects, etc. Having a basic engineering education will be a significant advantage.

Specialists in this field create a 3D model of an object, which will subsequently be printed. Today, craftsmen who can model metal parts, medical products, and all kinds of engineering prototypes are in great demand.

You can learn 3D modeling on your own using the content on the websites Demiart.ru, Gamedev.ru, Render.ru, as well as in thematic groups on social networks. You can also take online courses. Among the good foreign resources for online learning is Gumroad.

Software developer

Very sophisticated software is required to work with 3D printers and 3D models. Therefore, experts in this field are highly valued.

Knowledge of geometry will be a significant advantage, since today the specialty of the developer of geometric algorithms is especially valued. Also, software development requires full-stack programmers who know AngularJS and Ruby on Rails.

You can become a software specialist by completing a university thematic course, as well as through self-education. A good knowledge base can be obtained at Innopolis University.

Technician

One of the most interesting areas, which involves the development of new, better, more understandable and efficient devices. Knowledge in the field of mathematics and physics is important here. An engineering background would also be an advantage.

The most sought-after professions related to the creation of technology are assembly, electronics, optics, and mechanical engineers.

You can learn the intricacies of working with technology at the Moscow State Technical University. Bauman. However, to gain experience in the design of equipment is possible only in practice. In addition, along the way, you will have to master the technologies and 3D printers that already exist on the market.

Material developer

The characteristics and quality of finished products directly depend on the type and quality of consumables. Therefore, specialists in the development of new filaments, powders, etc. are in great demand on the market.

Knowledge of physics and chemistry is indispensable in this area. To get them, you can finish the chemistry department at one of the Russian universities.

I would like to repeat that theory does not make sense without practice. Therefore, after training, a 3D printing expert advises you to get an internship at any company that successfully operates in this field.

results of practice for students / Sudo Null IT News

Summer is the time for practice for university students. The Raccoon Security team regularly invites everyone to personal and group internships. This summer, students from the department of IU4 MSTU came to us for an internship. N.E. Bauman. For a whole month they took an active part in the production processes and put into practice the theoretical knowledge gained at the university. We decided to talk about this internship and share the feedback of the students who participated in it.

Internship format

The topic of the internship was “Developing the concept of home autonomous wireless camera for the safety of young children”. The internship was held in the practice format, ten students of the Moscow State Technical University named after V.I. N.E. Bauman, who have just switched to the third year in the direction of "Design and technology for the production of electronic equipment" (Department of IU4).

Initially, we planned the program for four weeks, for which the students had to:

research and analyze the market for stand-alone wireless cameras;

perform a circuit analysis of an existing set of devices;

field test these devices and compare their actual performance with the declared;

draw up the terms of reference, block diagram and concept of your device.

As additional events, we have planned presentations on the following topics:

Microcontrollers and FPGAs. What is it and how to live with it?

“Developing your device from A to Z”;

Introduction to 3D printing;

“Why study at PS4?”.

Students were divided into three teams of three to four people. Next, we created a chat in Telegram and a group in GitLab with separate projects so that it would be convenient for teams to communicate with curators. A workplace was prepared for each student: a computer with Ubuntu , fast Internet, Wi-Fi, air conditioning. To restore strength - tea, coffee, sweets and cookies ... :)

Goals

The main goal of the practice is to form basic knowledge about the key stages of creating a device. We wanted students to learn:

search and critical analysis of information;

team work;

systematic approach in conducting practical research;

registration of research results;

application of basic approaches to device design.

As organizers, we wanted to first of all involve students in personal internships with subsequent employment, as well as to make an overview of the current market.

Start

On the first day, the students showed their best side: during the introductory presentation and a short tour, they asked interesting questions and demonstrated knowledge in the field of applied electronics and programming. Someone already knew how to repair motherboards, someone was familiar with programming in C/C++ and Python , and someone developed apps on Android and iOS .

The next day we started the practice program. It turned out that students are able to qualitatively solve the tasks set much faster than we thought. Students have already begun to ask to quickly move on to practical actions: to introduce them to the development of microcontrollers (MC) and FPGAs, soldering and wiring printed circuit boards, as well as 3D printing.

We have decided to expand the internship program so that students do not get bored. I had to urgently supplement and rebuild the existing plan.

1. For soldering work, we have designed a board in the format pcb-challenge .

2. For tasks related to MC and FPGA, created separate projects in GitLab and distributed debug boards. For working with FPGAs, we prepared a small workshop on boards from the company Altera . Tasks for development on the MK (we chose STM32 as a platform) had to be thought out individually along the way.

3. For 3D printing, we moved one of the 3D printers to the students' classroom and showed how to use it.

Further on in the text we will give some excerpts from the feedback of our students. The spelling, punctuation and style of the authors have been retained wherever possible.

First week. Market Research

In the first week, the teams were required to:

conduct market research for standalone wireless cameras;

create a list of devices;

highlight the main specifications;

highlight the advantages and disadvantages of each model based on consumer feedback.

For each command, one of the highest priority search criteria was determined: image quality , miniaturization , availability of unique functions .

At the output, we wanted to get a systematic report in Markdown'e with tables and conclusions.

During the execution, one of the teams decided to apply their knowledge in the field of SQL - to create their own camera dataset and perform characterization using Python. We were pleasantly surprised by this unexpected approach.
One of the many graphs that students received after processing their database
Of course, for such processing, it is desirable to have a large amount of data, which the students learned about in the process and warned us in a timely manner. But we decided that in the framework of training we can neglect this. They designed the final report as an HTML page.

Cyril

To be honest, the first week was a bit boring, namely the analysis of the device market. But then everything was perfect. We disassembled the devices themselves, studied their principle of operation and what the elements of the device diagrams are for, and later we ourselves developed a functional diagram of operation for them, thought through what elements are needed and how they will interact.

Programming of microcontrollers based on STM32 was the most interesting for me. Alexander [curator] spoke not only about the basic things needed to work with MK, but also about the subtleties that were from his experience. In particular, when connecting the L3DG20 gyroscope, he said that the connection is only half the trouble, the main problem is data processing, which I did not believe at first. And now I'm studying digital signal processing...

Optional tasks. Soldering SMD components

Somewhere in the middle of the second week, our pcb-challenge board was ready. As soon as the boards "came" to the office, we decided to solder one piece and see how long it would take an experienced specialist to solder SMD components. Armed with a simple soldering iron, Nikita, one of the practice's curators, was able to solder all the components in about an hour.

The very next week students started trying their hand at soldering SMD components. Some students already had experience with a soldering iron, so someone spent no more than three hours on installation, while someone soldered all six.
PCB-challenge soldering process. The board contains LEDs and resistors of different sizes, including 0201 :)
Nevertheless, almost all students managed to install SMD components on their own. If the elements are soldered correctly, then all LEDs should light up with the same brightness.
The result is a personal keychain

Fedor

In general, I can say with confidence that this practice was surprisingly successful for me. I liked that the organizers of the practice approached the process of our training very responsibly: they arranged small lectures, helped with emerging problems. I especially liked the organization of our work: boards, tasks, To-Do List, etc. Still, the most important thing for me is people who are really interested in teaching us [students] something new, to tell and show – it costs a lot.

Second week. Circuit analysis

To perform circuit analysis, ten wireless cameras were purchased from AliExpress , , two of each model. It was proposed to disassemble one of the chambers, and leave the other for field testing.

Of course, it would be much more interesting to purchase certain models based on the results of the first stage, but given the time constraints, we decided to purchase cameras in advance.
Circuit analysis of some models
The students not only managed to find most of the datasheets for the discovered microcircuits, but also made quite plausible block diagrams of the disassembled devices.

Arseniy

The practice was excellent, it is worth noting the good atmosphere and the opportunity to ask questions, which are always answered and unclear points are explained. Didn't like a lot of reports at the beginning.

I learned how projects are carried out, what you can do in such companies, what things you need to know and be able to do in my specialty. You can reduce the number of reports and add even more practice tasks.

Optional tasks. Programming MC and FPGA

During the first week, one of the curators, the leading specialist Vadim, read to the students an introductory report about MC and FPGA. And by the beginning of the second week, we decided to do optional tasks on programming microcontrollers and FPGAs in our free time from the main program.

Six people wanted to work on hardware programming at once. Four students chose STM32, and two students chose FPGAs. We started programming the MK with simple tasks for blinking LEDs and studying interrupts. On the FPGA, students started by building the simplest counters on LEDs and seven-segment indicators.
In a few weeks, we mastered working with GPIO, interrupts, timers, UART and SPI based on STM32 from scratch
After completing the introductory tasks, we began to deal with UART and SPI. Among the tasks were the following:

sending commands to turn on/off the LED via UART;

counter transfer via UART when button is pressed;

calculator with UART interface and SPI display;

writing arbitrary strings to the controller's flash memory via UART;

work with ADC and PWM, adjust the brightness of the LED with subsequent display of the graph on the display via SPI.

Denis

The practice turned out to be quite entertaining. The informal atmosphere, communication on an equal footing contributed to the rapid rallying with the curators, and made it possible to quickly find a common language with them.

The practice program is quite interesting. Everyone, at their will, could get acquainted with the programming of a microcontroller or FPGA, the process of soldering and assembling their own circuit, printing on an FDM printer. In general, we got an indispensable experience, which one way or another will really come in handy in the future.

As for the FPGA, the students first implemented a simple counter with LED display and got acquainted with the PLL module. The next task was to create a counter on a seven-segment indicator, which could be increased and decreased by pressing a button. Here the students encountered such a phenomenon as contact bounce.

Unfortunately, we did not have enough time to complete the third task. It was designed for two weeks and consisted in the implementation of its own UART module, followed by sending and receiving a message encoded with a Caesar cipher.

But one way or another, we managed to get students interested in the development process on FPGAs. And one of them even ordered his first debug board from AliExpress :)

Timur

The practice process was not boring and varied.

In this practice, I learned:

1) more accurately analyze the market for certain devices;
2) conduct primary circuit analysis of the device;
3) test devices.

In my opinion, the practice went well. I liked all the stages of the practice, because the skills that I acquired will be useful to me in the future not only at school, but also at work.

32-bit counter project, high 4 bits driven to 4 LEDs. The accumulation of the counter is noticeable to the human eye. With the help of a toggle switch, you can change the accumulation rate
The next step was to conduct field tests. Very often it turns out that the characteristics declared by the manufacturer by AliExpress do not match the real ones. If this cannot be understood at the stage of circuit analysis, then real tests and measurements will help in establishing the truth.
A Full HD image taken with one of the cameras turned out to be 1280x720 resolution, and quite blurry at that
Here is a list of criteria and characteristics that the students used to test:
2) shoot in room lighting;
3) shoot in street light:
- in the direction of the sun's rays;
- against the direction of sunlight;
4) shoot in poor lighting:
- with IR illumination;
- without IR illumination;
5) check connection stability:
- image delay;
- image breaks;
- operating range;
6) check how the device works with storage:
- file organization;
- compression ratio;
- format.

Image in 2K resolution from another camera. In fact, all video and photos are shot at 360pA on this camera, the manufacturer also claimed 1080p, but the maximum resolution is 1280x720. Artifacts present
Our suspicions were confirmed: most of the declared characteristics did not correspond to the real ones. One of the cameras turned out to be simply inoperable, and among all the cameras there were only a few copies that could somehow shoot stably in more or less good quality.

It was very nice that the curators were graduates of our department. We very quickly found a common language. Thanks to the constant support of Alexander [the curator], the work has never stood still. In practice, it is very important that the curator has work experience, and we got it.

On the plus side, I would like to note that you can also learn more about how other departments of the company work, and not just about the one in which you are doing your internship. The work was divided into teams, but the projects were similar, so we all came together to perform common tasks and got to know each other better, which is undoubtedly great.

Optional tasks. Printing models on a 3D printer

By the middle of the third week, a specialist in the hardware development department, Nikita, gave the interns an overview report about 3D printing: the most popular 3D printers and the most common problems for beginners during printing were listed.
We tell the trainees about the basics of 3D printing and what kind of printer they can buy to start with
On the same day, we decided to transfer one of our combat printers, the old Felix 3.0, to the students in the classroom. The transportation was successful, and the trainees quickly mastered searching for models on the Thingiverse and working with the slicer. PETG plastic was used for printing.

We thought about doing some team 3D printing task, but unfortunately we didn't have enough time for that. Therefore, we simply limited ourselves to printing finished models on a 3D printer. Judging by the fact that a whole reel of plastic was gone in a week, the students liked it too :)
Students quickly mastered the work with a 3D printer and began to print different figures

sizes, even such as 0201 type resistors, analyze and propose various solutions to improve the electronic device.

I liked that all the specialists with whom I had any contact were well qualified. Every week, the most luxurious lectures of various profiles were held, which expanded the horizons and understanding of many things. Of course, in this extremely fleeting month it is impossible to cover everything, which is a pity.

Fourth week. Development of own concept

In the final stage, we wanted the trainees to draw up the terms of reference and the concept of their own camera, using the knowledge gained during the practice. As an additional task (with an asterisk), it was proposed to develop a 3D model and visualize your device.

One of the teams decided to make a camera based on the idea of scalable modules. Here's what they got:
One of the resulting concepts of a modular camera is a block diagram One of the resulting concepts of a modular camera is a 3D model in Autodesk Fusion 360

I can say that during the internship I significantly improved my soft skills. I understood what it means to work in a team, became more organized, sociable, began to systematically approach the solution of any problem. Throughout my work, I learned to critically analyze information and choose the right selection criteria.

I really liked that in addition to the main task, I was given the opportunity to get acquainted with microcontroller programming, create figurines on a 3D printer and master Markdown.

I would like to point out several advantages of the practice, the first of which is an excellent team of specialists and a great atmosphere.

Another plus is a cool work plan. It was very interesting to look at the key stages in the creation of the device. We were given the opportunity to come up with the concept of our own video camera, where I could show my creative skills.

As a sophomore, it's hard to imagine what we can expect at the place of work, and the practice of this format gives a very clear and clear idea of what we will face.

Conclusion

The month flew by unnoticed, and the practice came to an end. All tasks assigned to the students were completed qualitatively and on time. During the practice, we conducted several interviews and agreed on subsequent personal internships in individual areas. As a conclusion, we quote the words of the chief curator of the practice - Alexander.

Alexander

Initially, I had some doubts about how the internship would go, because it was my first experience of managing a team, albeit a small one. All doubts quickly disappeared as soon as I saw the burning eyes of students and interest in development and programming. We very quickly managed to build trusting relationships and find a common language with students. I enjoyed challenging them, guiding them and answering questions. In the process, I also learned a lot and outlined new points of personal growth.

I hope that this month I was really able to interest and teach the trainees how to develop their own devices. Lay a small foundation for programming and further interest in microcontrollers and FPGAs.

I would like to thank all the students and my colleagues who helped me to conduct this practice and made presentations: Kirill, Nikita, Vadim and Anton.

We constantly conduct individual internships and would be grateful if you share a link to this article with those who might be interested.
