Designing and Manufacturing a Custom PCB for a Micro Blimp

Recently, I've been very interested in creating circuit boards for my various projects. However, in the past, my boards haven't been much more than basic breakout boards; they simply rerouted existing traces away from the GPIO of the SOC or microprocessor I was using, and placed them in accordance with the footprint of whatever sensor breakout board I chose. In fact, I had never truly completed a PCB project using anything more than off-the-shelf sensor modules. This project has been my first deep-dive into actual circuit board design and production, and I've learned so much along the way.

Building a Distributed Computing Cluster with Udoo Quads

I have recently found distributed computing to be an interesting subject for me. The ability to combine multiple single-board computers into a powerful parallel-processing system opens up a world of possibilities for learning, experimentation, and performance improvements. So, I decided to build my own DIY computing cluster using 13 Udoo Quad boards running Armbian.

How I Built a Thermal Camera from Scratch

Thermal imaging has always fascinated me. The ability to "see" heat opens up a whole new dimension of perception, making it a powerful tool for diagnosing electrical faults, detecting insulation leaks, and even exploring the world at night. So, I decided to build my own DIY thermal camera using a Raspberry Pi, a thermal sensor, and a custom circuit board.

How I Built a DIY Desktop Variable Power Supply

A desktop power supply is, in my opinion, the single most important tool for an electronics engineer to have (after a multimeter of course.) As such, building my own from an old laptop power supply was an essential step in my ECE journey, and I learned a lot about the basics of electronics design along the way.

How I Built a DIY Digital Microscope

Like most of my projects, I got my inspiration for this one by through Youtube. Specifically, I saw this video ([Brauns CNC](https://www.youtube.com/watch?v=jzcHGjFiR0o)), and I was immediately hooked on the idea of building my own digital microscope. Although I had never experimented with using a camera module on a Raspberry Pi, I dove in headfirst.
