I mounted four Raspberry Pi 3’s in an acrylic stack frame, and used a 5V 20A DIN rail mounted power supply to drive them all.

A while back my kids got this SOS station toy, it came with a few emergency cars and the boys quite liked it. My girl friend and myself however; hated it, it had a speaker and made a high siren sound and an annoying voice would shout things like “all cars respond”. So I modified it; ripped out the speaker and mounted a few LEDs instead, so now it flashes but no sound.

I’ve gotten myself one of those ultrawide curved monitors. I’ve wanted one for a long time, and I finally bought one; a Samsung 34". Since my desk is pretty shallow, and not that big really, I also wanted to free up some work surface by getting things on shelves. So I’ve been doing a bit of work on my computer setup.

Bias lighting is, simply put, to light up the wall behind a monitor or TV. It creates a glow around the screen and, supposedly, creates a more comfortable and high contrast viewing experience. I made my bias lighting by merely sticking a LED-strip behind the TV.

My two twin boys are pretty into Fireman Sam these days, so the red walking car they got when they were babies got an upgrade. Four blue self-flashing LEDs, a toggle switch and a 2xAA battery holder; everything bought cheap on eBay. And voila! A fire truck with blue emergency lights.
