It's been over a decade since all of my 8x8x8 LED Cube Tutorials - glad to see people are still finding them useful today! Look at this amazing cube build by Warren!

wow, just had chatGPT solve a bug for me - had an old Processing Sketch that was failing to compile in v4, was importing both serial and io libs and was getting a "Serial is ambiguous error" threw that into ChatGPT - and instantly told me what to do! Pretty crazy!

First draft working! Completely standalone UPDI programmer from an SD Card! My code here: github.com/krdarrah/UPDI_… and you'll see a link to my fork of the Adafruit_AVRProg lib

Anyone interested in this idea? Standalone UPDI programmer? Burns files from an SD Card to target. Been playing around with this for a day or so now...

My FTDI based USB-Serial Converter has been out of stock for months... finding genuine FT230X parts right now is nearly impossible! Refreshing an @octopart tab every day, finally scored some from @alliedelec - Now we're back in stock! tindie.com/products/13817/

@KDcircuits Cool, a WiFi connected NCV (Non-Contact Voltage) detector. I guess it will send a message thru wifi whenever the switch is on. That NCV pcb is quite familiar.
