Protection Charm

Take your standard 74HC04 IC chip. Bend in pins 2-13, solder them together if you like. Onto pins 1 and 14, solder on a small (1/8 - 1/4") metal ring, like a split ring for jewelry making. Run a string or black necklace cord through the rings, or even clip on some alligator-clip leads, and *poof* you have your very own Hex Inverter! Wear it to

Brilliant! I think I'll be making one. But just to be safe, I think I'll add a ceramic bypass cap between Vcc and Gnd. It is just good electronic design.

Would you use a disk cap or a cylindrical one?

[straif]

The ceramic caps are the little nondescript disk-shaped ones. 0.1µF would be a typical value.

I know that, but I know that there are also ceramic caps that look more or less like resistors, even though they are less common... many IC sockets come with built-in caps, mostly of the latter sort.

I saw this linked on Make at the weekend: http://35pixels.blogspot.com/2007/10/making-hex-inverter-for-spectral.html

*laughs* that's pretty funny. I made mine a couple years ago, and passed a bunch out as nondenominational winter holiday gifts to my friends. They were a huge hit. Never thought of using copper antennas though, that's a great idea.

I love it!
