PSoC POGO Programming Adapter

When I was doing a lot of AVR Programming, I had a few ISP pogo pin programming adapters (example #1, example #2) that made programming very quick and easy without using a dedicated connector on the target PCB. I’ve being using the Cypress PSOC microcontrollers with the MiniProg3 programmer and wanted a simple POGO pin adapter that I could use with it. I didn’t find any that were currently being sold, so I decided to make my own. Honestly, I (more)

Nixathing

Nixie clocks have been all the rage in the electronics hobby for the past several years. I had a student, Jordan Easter, design and make one when I was teaching at Surry Community College, and it turned out great. (He did it all using perf board, Yikes!) It had been on my to-do list for some time to make one myself, but it seemed I could never find the time to get around to it even though I had already (more)

When I was teaching, I had a friend of mine ask me if I could review a grant proposal that his startup company (OtolithLabs) had written. In the proposal, they discussed a new device that would help with motion sickness by applying low frequency audio (or even sub audible frequencies) behind the subject’s ear. In the proposal, they had piecemealed a couple of Adafruit boards together to demonstrate feasibility for their new device. What they needed was an electrical engineer (more)

About Me

I work in the semiconductor manufacturing industry by day, and I enjoy working on electronics projects by night. I started this blog so that I could document the projects I'm working on and what I may have learned along the way.
