This is a super small note more for myself as i forget how to do this everytime ive wanted to do. There isnt really much documentation on the internet about how to import objects into Terraform when using the Authentik provider. As i have recently done this, i figured id note down how i did it. Ideally the docs would be updated to include this, but at time of writing they dont. My usual flow i...

Over a year ago i built and LDO Voron V0.2 sold to me by 3djake.uk. It was my first venture into the Voron world although not my first time with a premium DIY kit. I have built and use a RatRig Vcore3 and have upgraded it to a 3.1 with every upgrade RatRig released. I really enjoyed building the V0.2, all the printed parts was printed on a BambuLabs X1C which i bought through the kickstarter w...

Just thought this would be a good spot to introduce the first API i have built. Its currently hosted at grid-data.co.uk. It is quite a simple API with only a couple of endpoints at the moment, but it gives an almost live view of the UK power grid. Showing how our energy is being generated, be it via gas, nuclear or other. This is heavily based on the work of Kate Morely and her very informati...

I recently bought a tortoise (named Burrito) as a little buddy in my office. He’s a cool dude, only about 18 months old so pretty small. Due to work and kid commitments i was struggling to remember to turn his heating on, so i needed a way of automating this. - [The plan](#the-plan) - [Hardware Used](#hardware-used) - [Software Used](#software-used) - [ESP8266 Setup](#esp-8266-setup) - [Wiring...
