A partially-automated medium-throughput homemade cider press with lasers
Most people who know me well know I really like apples.

A USB Fan Controller that now works under Linux
Relying on the built-in motherboard headers on server grade motherboards to reliably control fans with Linux has been a crapshoot since forever. I'm pleased to report that last summer the Corsair Commander Pro received native Linux kernel driver support in the 5.9 release.

Solar Shed Summary: My Off Grid Office
A few months ago I moved to a few acres in the country, and needed somewhere to work - so I built myself a solar powered off grid office out of a Tuff-Shed Pro Studio! On one side, I’ve built a great desk corner with plenty of power and more than enough AC to keep me cool when it’s over 100F out.

Gentle introduction to GPUs inner workings
This article summarizes some lower level aspect of how GPU executes. Although GPU programming is not that complicated when compared to CPU, it also doesn’t match to what hardware is doing exactly.

I bricked then recovered my reMarkable 2
Let me start by saying that the reMarkable 2 is a great device.
