Some Fun with Claude I've had some downtime, recently, courtesy of a couple nasty health issues (no, not cancer).  In order to relieve some of the boredom while recovering, I started sorting through some of the electronic "stuff" I've accumulated for projects which, in turn, never seemed to get done.  I can across a ESP32-S2 feather - the one with the built-in TFT display - and thought it might be fun to turn it into a cw decoder.  (Yes I know such things are no substitute for the ability to copy by ear, but remember, I was bored.)  I'm also not a big fan of "vibe coding" but for this exercise I though it'd be interesting to see what Claude could do.  Some I told it:   1. Target device is Adafruit ESP32-S2 TFT Feather board. 2. Will be using the current Arduino IDE for editing, compilation and uploading. 3. Input will be raw audio on analog input A5.    a. Audio input will be line level (2.00 volts - high impedance). 4. Decoded text will be displa...
