Parallax Feedback 360 and Arduino

A problem that I have with hobby servos is that they typically don’t have 360 degree rotation and positional feedback. That was until the Parallax Feedback 360 was released. In the adafruit product video (3:41) they actually crack the little guy open so you can see its guts. Basically it’s a normal continuous servo that uses a AS5600 contactless hall effect sensor that gives positional feedback as a pulse train.

Machine Vision and OpenCV

Today has been pretty productive. I’ve released a second open source project, a Python Serial Monitor and I’ve been working on some machine vision projects that I’ve wanted to do for a while. Back in the day I wrote a bot for a game I liked playing. It would read my computer screen and then […]

Sometimes you don’t want to share. That’s what this post is all about. Intentionally not sharing code and data. In this project, I wanted a private Git repo that I could access on my network through SSH.

DIY USB Keys

I have many passwords. I also apparently have “security fatigue.”

What sucks is that I need my passwords to be stronger. I can’t remember them when they’re auto-generated and entirely random. There ARE solutions to my problem out there, like Mooltipass, Yubikey, and the U2F Zero. These are very cool, but the U2F Zero isn’t available at the moment, Yubikeys are $40 a piece, and Mooltipass is $79.
