I wonder what my tarrif bill is going to look like for these :( Ordered before all these shenanigans and they were finished and shipped at the 145% mark.

This one makes me the most nervous from any other pcb I have made because of the 120vac heating element. Getting ready to turn it on with firmware.

All ready to go now. Time to write some firmware for this esphome esp32 custom replacement board.

I did not like the bluetooth app that came with my multimeter so im making a esp32 web app instead. Not too bad so far, just have to figure out the serial data structure. Anyone want to help?

I messed up the orientation on a esp32 board i2c header so now i made 500 of these little orientation flipping tiny pcbs.

New boards came in. Getting ready to test esphome on these

An esp32 filament dryer replacement board im working on.
