My old breadboard was starting to get a little tired so I thought it was time to update it and to something more useable. The old one was homebrew more or less, but how it was being powered was becoming a nightmare to use.So i grabbed one of these of ebay, and with a breadboard power module i have 12v 5v and 3.3v as well as USB power out. All in all this will be much more usable than the old board.
The 4th project, while no where near complete is a capacitance touch iambic keyer. Well, its not really a project but a proof of concept, and it kind of works ok and is going to be something that i develop more as i have time. The micro is an ESP32 which has 10 capacitance touch sensors built in. I used a modified version the the morse library that’s available on the net for the timing and keying and connected a peizo buzzer to act as side tone. To key a radio all you have to do is set a digital pin high and pull it low when you want to key the transmitter. And as the code takes care of the timing, you could use this on any transmitter that uses a straight key and pulls to ground on keying. Most of them LOL.
