Fixing a Simple Button & LED Circuit
I found an old Christmas ornament which was supposed to light up by pressing a button. Before trashing the ornament, I tore out the circuit. While I was taking it apart and figuring out why it didn’t work, I turned on the camera and talked to myself. Probably boring for most people, but it might be interesting to see what I was thinking through the process. If you’re new to electronics (like me) it may even teach you a few things.
This is completely raw and unedited footage. Sorry about the noise in the background. I was using an electric heater because my boiler wasn’t heating up the house properly.
Testing: RGB LED Strip, EL Wire, and Endoscope
I’ve been meaning to test out several new products I bought. Figure I would take the camera along for the ride.

Test LEDs with a Coin Cell Battery
The battery (CR2450) in my garage door sensor was getting low, so I replaced it. I’ll keep the old one in my electronics kit for LED testing, as shown in this video. Touch the longer leg (anode) of the LED to + and the shorter leg (cathode) to –. Usually + is the top of the battery where the words are. Don’t worry, you won’t hurt the LED if you connect it the wrong way.

Who would have thought it would be so exciting to light up some LEDs? I had a late night playing with a breadboard for the first time. It was also my first time soldering anything. I had to attach some headers to a Raspberry Pi Zero.
