A Variable Benchtop Power Supply from an old PC

 

Do you have an old PC tucked away in a closet somewhere?  Repurpose the power supply from that old desktop into a modern fixed and variable benchtop DC power supply with little (or even no) soldering and just a handful of parts.

StreamPi - Build your own Stream Deck!

 

If you are a streamer, having a configurable stream deck to control your video and audio feeds is almost a necessity. Even if you don't stream online, a stream deck can be a handy device.  But commercial versions are expensive.  Instead of spending hundreds of dollars, you can create you own with a Raspberry Pi and maybe even some devices you already have around the house.

These animatronic props have LED eyes that change color, a rotating head and optional sound that all activate via motion detection.  Alternatively, on board motion can be disabled and all features controlled via automation (like Home Assistant) using MQTT.
