Home Automation – Kubernetes Style

I’ve been using Smartthings as my smart home hub for a while. And I’d like to migrate to something that’s open source (or more importantly, self-hosted). There’s been a few horror stories out there that make me worry about the potential “hostage” situation. (e.g. manufacturers charging a monthly price for the service, or flat-out discontinuing…… Continue reading Home Automation – Kubernetes Style

Upgrading K40 Cooling System with RGB and Peltier Cooler

The K40 laser cutter, if you know about it, comes with absolutely the bare minimum to get you started. Fortunately, it does comes with a cooling solution: You supply your own water bucket, fill it with distilled water, and drop in the supplied water pump. Failure to do that will probably result in a burnt…… Continue reading Upgrading K40 Cooling System with RGB and Peltier Cooler

Using Makefile for Non-programming Tasks

Make is traditionally used to build artifacts from program source code. It can also be used for other tasks, where you need to “build” something out of a “source-of-truth”. For example: video-editing. I personally find ffmpeg able to generate better quality compressed videos than FCPX or Premiere Pro, which is especially important if the desired…… Continue reading Using Makefile for Non-programming Tasks

LAN Party VPN – My experience with WinTun, Windows Firewall, NSIS and Windows Defender

I’ve recently made LAN Party VPN. It makes playing LAN games with friends on Discord effortless. LPVPN is written in C++, mostly because Discord SDK is only available in C, C++ and C#. So I didn’t have much of an option here. The idea of LPVPN is rather simple, get IP packets from WinTun (the…… Continue reading LAN Party VPN – My experience with WinTun, Windows Firewall, NSIS and Windows Defender

Wasmino = WASM + Arduino (Running Arduino code in browser)

Wasmino Running the “Fade” example Wasmino is an Arduino core fully compatible with the Arduino IDE. It allows you to compile your Arduino sketch to WebAssembly and run it in a browser, all using the Arduino IDE. Showcase This is the off-the-shelf “Fade” example in the Arduino IDE. /* Fade This example shows how to…… Continue reading Wasmino = WASM + Arduino (Running Arduino code in browser)

R5 Thermal Mod, take 2

Pretty much the same idea as the previous attempt, but with graphite sheets to conduct heat better (I’m using Panasonic PGS sheets). This is 100% not recommended because the graphite sheets are conductive, and are more likely to cause damage.
