Building electronic devices and kits, repairing electronics and
learning about components and their uses.
During the New Year Show Ken soldered a component tester. Unfortunately this did not work.
NYBill offered to fix it and he succeeded in his show hpr2591 :: International Troubleshooting. When he shipped it back he included two 555 timers with the message: Now, figure out how to make LED's blink
with those 555's!
In this show Ken uses the online guide FLASHING L.E.D. USING 555 TIMER By Trilesto to do this.

Ha ha, nice job Ken. It made me smile when I heard you happy it was finally blinking. And we got some live troubleshooting as well! Good stuff.
You know how I remembered which way a LED went way back when... One leg of the LED is cut off. 'Cut Off' starts with a 'C'. So does Cathode. The short leg is the cathode. If you had your leg cut off, that would be a pretty negative thing. The short leg is negative.
Just a little mnemonic device I made up to help me remember. I still think of it to this day.
Now, you just need to build one of the oscilloscope kits. You know, to see how fast your LED is blinking.
See how I did that? Its how we get more shows. ;)

These troubleshooting shows are one of my favourites. I did tinker just a tiny bit with electronics at school, but never invested enough time to really understand what electricity is all about. Especially the analog electronics is sort of black magic to me :)
But I love listening when someone is working with it, explaining what they're doing and slowly working their way through a problem.
