This is a follow-on to my previous post on this device.

This page contains essentially my notes on reverse engineering the ATorch DL24 electronic load.

A friend recently suggested that putting their Sony A7ii camera in airplane mode improved their battery life.

I’m running Klipper & Octoprint on my Orange Pi Zero to control my 3d printer.

I had a lot of trouble finding a correct & minimal ESP8266 schematic, so here’s what I’ve ended up with: ESP-WROOM-02 To program, hold SW1 while connecting the power pin.

The Ender 5 contains a Landy LRS-350-24.

Update We have a working ESPHome component for the Emporia Vue 2, thanks to the hard work of Alexandre-Jacques St-Jacques and Kodey Converse!

I’ve recently purchased a RF LED strip controller, and it came with a remote.

These are some personal notes for working with nRF52 hardware.

I’ve recently purchased a Logitech MX Master 3.

Embedded systems these days frequently need to serve up HTML pages, but in most cases, both the processor and the network interfaces are very slow.

One annoying thing that banks like to do is to timeout any sessions that don’t have activity for a certain number of minutes.

I was having some trouble with it takeing about 10 seconds to resolve names on the local network like tight-seat.local.

I really enjoy the way that the following schematic looks, so I might as well document the process of creating it before I forget.

Correction: A previous version of this post said the resistors were 10Ω.

I’ve been having trouble resolving domains on my laptop after resuming from sleep, i.e. trying to load a website gets stuck forever since the system isn’t able to resolve “google.com” to “64.233.185.101”.

Introduction Many packages don’t have KiCad footprints, and KiCad’s system doesn’t exactly make it the easiest to create create footprints from a drawing.

Track down the servers Open up Wireshark, and start a capture on the interface the rouge servers operate on.

This was a massive pain, so I’ve written up this post for my reference.

When redesigning this website, I wanted a subtle paper background texture.

Our incredibly polished final product.

I’ve spent 3/4 weekends over the past month developing various things for hackathons, and one of the most interesting ideas that I’ve come across is using Azure’s Face API in physical products.

I attended HackGSU again, and again had a great time and won second place!

I attended HackGSU last weekend, and it was my first hackathon.

At some point, I ran pacman -Syu and was surprised to see that I could no longer connect to the internet from my phone!

I planned to write a game nearly 3 years ago (wow, it’s already been 3 years!).

Using Nim with CircleCI is fairly easy, the same instructions can be used for bootstrapping as usual.
