This week we are back to the Tech Night Radio project. I now have most of the schematic done and getting ready for the proto board layout. We’ll go over some of the schematic, then I want to talk about one of the most useful and cheap electronic parts there is, the XOR logic gate. I’ll show how it can be used as a buffer, inverter, schmitt trigger, level translator, polarity control, frequency doubler, phase detector, relay driver, and maybe other things I think of. And it’s 8 cents! I will also bring in the latest electronic mouse trap and show you what’s inside. There is very high voltage…
Hope to see you there.
