Nick Momrik: Trying to get a hole-in-one
I wired a 9V in series with two AA batteries (1.5V each) to test out the truck‘s dash panel bulbs.
Turns out the bulb holder I tested first was faulty and 9V would have been enough. In fact, three of the nine bulb holders were corroded and unable to provide juice to the light bulbs. That explains why it was so hard to see the gauges at night!
To get by until new parts arrive, I was able to finesse some small pieces of wire in between the bulbs and the holders to get an electrical connection.
Quick unboxing video for the latest HackerBox.
Official box contents from the Instructable:
It’s disappointing that HackerBoxes resold us a popular kit that you can get for $15-20. I’ve seen these LED cubes many times online and while they do look awesome, I never bought one because I didn’t think I’d have the patience to put one together. I guess I’ll get the chance now.
I’ll probably try to do a time-lapse of this assembly, which is going to take a long time.
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.
I’ve been meaning to test out several new products I bought. Figure I would take the camera along for the ride.
Items in the video:
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.
