The Aethereal Echo is complete now!
This was a fun project, which took me way more than I hoped.

On the chain of a hanging flower basket sits the only insect capable of turning its head.
It is looking at me.

The text reader pronounces ESP32 as 'Thirty-two Spanish Pesetas.' 🙄
I noticed this 6 months ago; have they really not fixed it?
Is it actually rarer to discuss microcontrollers than old Spanish money?

Individually addressable LEDs.... so cute! They look like regular LEDs except... they have 4 pins: +5V, GND, Data In, Data Out. 5 and 8 mm LEDs

Today's thrift store find: Melcor 400 harking back to mid 1970s.
It is surprising to see buttons dedicated to square root while many other calculators did not have such functionality.
The interesting part is that the calculator goes into a 'power saving' mode by blanking display except one segment.

Another thrift store find: Elsmate EL-8151 calculator from 1970. The calculator sports VFD display and a printer. However, this is not a thermal printer but rather spark printer. The spark printer uses a conductive paper and electric current to burn away dots of the printout.
