Bring Back the Magic of Radio! 📻✨
Ever wanted to broadcast your own audio over the AM band? I just came across this fantastic DIY guide by VU3DXR on how to build a Micro-Power AM Transmitter.
Check out the full circuit diagram and step-by-step instructions here: 👉 https://vu3dxr.in/build-your-own-micro-power-am-transmitter/

I fixored my Hamilton Beach toaster. 🪛 
The solder joints on the electro magnet that holds the lever down had broken completely.
My Soviet Germanium PNP class A transistor audio amp works! Needs a little tuning but sounds pretty good! Definitely “old Fi” rather than hifi but that’s what I wanted. This was based on a circuit from MIT but seriously modified b/c of the transistors I had available. I’ll post a schematic. Very happy I got this working well!
Transistors are 2x MP-39 for voltage gain and 2x P-214G Darlington power transistors driving 8ohm cheap speakers.

Nothing annoys me more than people who peek at their Christmas presents early. I built a "Present Peeker Trap" that sounds an alarm, records and video, and pings my phone if someone peeks!
