What could possibly unite lipids in a cell membrane and parallel universes? If you think of natural selection as the persistence of a system over time, you can extract this pattern of thinking and apply it to the fundamental physical phenomena as well. Let’s do some disambiguation first! One should pay special attention to phrasing …
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 …
During Summer break, I got a chance to make some liquid art in ProTvorchestvo art studio in Almaty, Kazakhstan. I later converted that art piece into a watch face with some of the shelf watch mechanisms. I think it turned out grear!
I had an idea for a solar tracker system that has two axes controlled by a single motor. It looked great on paper but a major flop in reality. I made pretty significant mechanical simplifications in my design which accumulated into an unstable (yet somewhat working) structure. I designed and manufactured the mechanical system myself, …
My adviser and I partnered up with UML’s Plastics Engineering department to work on the new design of a light-weight solar panel. Following are some excerpts of our previously published works: PV solar energy’s initial investment is affected by shipping, handling, and operating costs. These are directly related to solar panel’s weight, frame structure strength, …
Our team at AETC came up with a solar panel defrosting system using the solar cell itself as a heating element. After further research we found out that similar approaches were already patented in 2015. We then further simplified our system to aim for a reduced cost due to distributed converter system. Our experiments showed …
