Unpacking two items from the mail while rambling on (Reupload!) …
↓↓↓ Complete description, time index and links below ↓↓↓
Reupload: This is the same video as the one originally published on December 12, 2020! Just some private information has been blacked out.
Leave it to me to draw out a mailbag video featuring just two items into a fourteen minute video. But I had some stories to tell my spouse wouldn’t listen to.
Anyway, I’ve got some double sided SMD circuit boards designed by Limpkin for HB100 radar modules (links below) and a MAX31855K module. The latter is the more capable version of the MAX6675 (see links below).
00:00 Intro – just two items
00:04 PCBs – designed by Limpkin for HB100 doppler radar breakout board
09:14 MAX31855K – module for type K thermocouples with SPI interface
13:26 Wrap-up – group picture with some PCBs and a MAX31855K module
