In 2018 I felt that I didn’t have enough OOP experience and decided to try myself in app development. Context: In Kazakhstan like in many post-Soviet countries, local government officials are not elected, but are assigned from the central government (which is, frankly, often corrupt and de-facto authoritarian). Consequently, the incentive landscape for the local …

Just a small weekend project. Ideally, I was supposed to be able to see my breath or warm air flow off my hands. Might return to this in the future.
Here is a draft design of a simple buck converter. Hope you find it useful! PART I: DESIGN PART II: ASSEMBLY and AMENDMENTS
I wanted to practice my embedded control skills, so I made a simple constant-current LED driver. I assembled the hardware based on SDG Electronics’ design and wrote a C code for current control. This code senses current through LED and keeps it at an average value of 350mA by modifying the duty cycle of a …

Check out my shortcuts in functional reverse engineering of common consumer electronic products. I hope you enjoy!
As a part of Prof. Cheney’s Analog Devices and Techniques course at UMass Lowell, students are challenged to design and test an OpAmp from a base circuit. This is a group project and the team with a highest gain gets to skip the final for the class! Scott, Yassine, and I won this semester’s competition …

I am building a plasma arc speaker using Proto G’s design. I named this project “бір мың құс” and engraved it on a wooden platform with a soldering iron. The name means “One Thousand Birds” in my language for the peculiar sound the plasma arc makes. It is a tribute to Sasuke’s Chidori which bears …
I built an analog synth using Ray Wilson‘s open source circuit designs and made an hour long analysis of its VCO circuitry to contribute to the open source community. This project could have been completed in a couple weeks, but took me around 9 months because I was working on it while also preparing for …
I volunteer at Lowell Makes, a local non-profit MakerSpace, as an Electronics Co-captain. We had a couple of old oscilloscope units lying around and we decided to use them as scope music display units. Oscilloscope music is a music file specifically designed to be displayed on a regular oscilloscope. The music is written in a …
A good fraction of my theoretical research is on the design of semiconductor devices (primarily heterostructure solar cells, HBTs, HEMTs, and FETs). It was, however, critical for me to be familiar with the device manufacturing steps as well to be able to account for them in my designs. Moreover, manufacturing limitations and practical deviations from …
