I've often wondered how much of the power bill was my gaming PC, or my smart home gear, or even an air-conditioner, but I keep forgetting the math. Let me write some of this cool stuff down.

My new home came with some solar panels and a Delta Solivia inverter. I'm envious of new inverters that give you cool graphs and statistics on your phone. Can I make my own wifi bridge to push solar power data to my Home Assistant controller?

How do you know if you received that data correctly or whether your saved settings actually saved properly? By using a fast and easy CRC check, that's how! Here's a quick guide on performing CRC checks on data with your favourite microcontroller.

After moving house, I was having really bad signal issues with my Zigbee devices that I used in my smart home. After researching and fiddling around a lot, I fixed it and learned some skills along the way! Here's how I did it.

I wanted to be able to talk to an Arduino controller, make changes and make it do things without needing to reprogram the damn thing every time. I suceeded! Here's how I did it.

My CyberPower Value600EI uninterruptable power supply stopped working after I moved house and wouldn't turn on. Can I bring it back to life?

I'm terrified of accidentally leaving the garage door open. Lets see if I can watch and control it from my smart home?

Here's an easy and portable DIY battery box I made to go camping with my medical CPAP machine. It's also much cheaper than the official battery pack, and I can charge my phone from it too.

IoT devices use MQTT for a lot of things, but why is it so difficult when they use MQTT to send files, pictures, and videos?

Switching a computer between headphones and speakers is fiddly and annoying. Let's build something to make it easier!

In Arduino controllers, millis() rolls-over back around to zero after 49 days. How can you avoid the problems this causes?
