Automating Air filters

Recently I was watching a Thomas Sanladerer (Making with Layers) video on youtube about the emission of gases from 3D prints. Like Thomas, I am concerned about the fumes that come from my 3D printers and I'm interested in ways to reduce them, especially around my young son.

Kestra webhooks and Home assistant

Welcome back to another blog post on Kestra. Starting from where I left off last time, I'm going to try to fix a few little niggles I had with the time based triggers.

Living without Wifi

My Ender 5

I have been 3D printing since COVID. Like many others, I decided I needed a new hobby to spend my time at home on. Shame it was still tied to computers, but it was sufficiently different to distract me. The printer I chose was an Ender 5 pro.

Epaper Displays and waste management

So, if you have read any of my other posts you may have already setup your waste management reminders and your epaper display access point(s) and tags. So if we have both of these things, why not combine them?
