3Description

The AZB-12 is a PCB designer and embedded engineer in a single, human-sized package. It was made in Uzbekistan, it's in grade 12 at Tashkent Presidential School, and it mostly makes circuit boards: flight controllers, CanSat electronics, and boards that teach other kids to make circuit boards.

Hi, that's me, Azizbek ^-^ Everything on this page is true. It's just laid out like a datasheet. Every project has its own page at [project].notazizelse.xyz, like camp.notazizelse.xyz.

7Detailed Description

7.1Overview

I got into Tashkent Presidential School in 6th grade and started competitive programming the same year, in C++. My best result was 4th in the regional round of the informatics olympiad.

Then I found LEGO robotics. My first sumo robot got horribly humbled at its first competition. My biggest LEGO build was a fidget-spinner factory, an actual little assembly line.

Me in a hard hat and work jacket, giving a thumbs up next to a laser cutter — **Figure 7-1.**Device in its natural habitat (a workshop, next to a laser cutter).

7.3Feature Description

After that I moved to Arduino. I cut sumo and line-follower chassis out of PVC foam board by hand and won 1st place at the national robotics championship. Later I drew the same chassis in Fusion 360 and sold it online as a national champion design ^-^

In summer 2025 I interned at Intelligent Software, assisting the lead electrical engineer on a laser marksmanship trainer that fires no ammunition. I worked on the beam collimation and the PCB. That's where I met STM32, and that internship changed how I think about engineering more than anything before it.

My next internship was at Unique Dynamic, an agricultural tech company. Over about ten months I built a flight controller from scratch (schematic, PCB and firmware) for a drone that sprays pesticide evenly over a field. Getting the spread even was the hard part.

On the side I do CAD. I designed a jet engine in SolidWorks and printed a small version, reverse-engineered a car fender from a 3D scan (got paid about $100 for that one), and sell models on Cults3D. Nobody bought my Harry Potter model, smh.

With NazarX, an FTC team, I was the CAD engineer for the turret and the compression system that feeds it. I replaced the HD Hex motors with servos and learned what tolerances actually mean. The team got 1st seed at Almaty Tech Cup XII and made the finals there and in Sanya, China. I also led our FIRST Global Challenge team for a season, which was mostly splitting up tasks and keeping seniors who were busy with uni applications on schedule.

Technocamp 2026 is the biggest thing I've done. I was the lead electronics teacher at a 200-student camp in the mountains, for kids aged 12 to 17, most of them from low-income families. Every student designed a PCB and etched it themselves. I wrote the curriculum, the chemical safety rules and the budget, and designed the board we used. Right after that I taught at a five-day STEM camp with the U.S. Embassy, and we showed our FTC robot and CanSat work to the President of Uzbekistan.

Long term I want to bring FIRST-style competitions to Uzbekistan, and after that TEKNOFEST. Right now only a couple of teams from here compete seriously abroad, and I'd like that to change.

7.4Device Functional Modes

Swimming: Regional champion.
Karate: Champion, Samarkand.
Knife throwing: National runner-up. It's a precision target sport, I promise.
