RF probe

Step 2 Connect it up

I used a small sliver of circuit board to hold C1. The turned pin socket was fitted to one end, the capacitor C1 soldered to it and then the resistor and diode leads formed to shape and soldered to the capacitor. It is shown next to the stereo earphone jack in order to see whether it will fit. Adjust sizes, get a smaller capacitor etc until it does.

The socket, capacitor and supporting board will go inside the barrel of the jack.

i never knew what those clear things with the colors on them are until now, why do i only see them on tvs and monitors?

What kinds of things do you take apart? I find so many signal diodes (1N4148's typically) in trashed electronics I don't bother desoldering them anymore. (Besides, they're cheap enough that using a new one in a project is less troublesome than using a damaged scrap bin diode.)

I take apart everything that i can get my hands on. =)

Me too :3
I prefer early 90's or late 80's era devices, before everything went surface mount.
If you take recent products apart, you'll be quite disappointed at the component yield. You've probably seen few discrete signal diodes because manufacturers cram everything they can into ICs to reduce component counts.
On the other hand, an early 90's handheld four-in-a-row style game I recently took apart (lack of backwards current protection fried a LED ) has 34 discrete transistors in it!
Try going through free piles after garage sales or the free section on your local craigslist boards.

Old CRT TV's probably have the best stuff in them. Whenever I take apart new things I put the boards in the toaster oven or i destroy them.
