All that and it will even plug in nicely into a breadboard, terminal block wing, or Feather Doubler or even just stack on top of another wing.

@derek sure, it’s a small 6V peristaltic pump that moves water from a 100L rainwater barrel from our house up to a second barrel which is in our higher level garden (up 2.5m) as I’m too lazy to carry the water up.

Tech wise it’s now a waveshare #esp32s2 pico which controls an #adafruit boost 1000c to control the pump, enclosed in a cheap wooden bird box. It’s powered by a #solarpanel and charges 3 supercapacitors in series. Code is in #circuitpython and takes advantage of deepsleep

Water Pump Update: sadly slow progress rebuilding. I’ve found that #RaspberryPiPico just doesn’t have a good enough deep sleep state to survive the night on the supercaps so I’ve switched to an #esp32s2. But then the ESP32 board I got turns out the pin out isn’t correct so spent ages trying to work out why the adc didn’t work.
Currently testing how this new board functions attached to the #solarpanel

It’s a little frustrating as it’s holding up all my other projects!

Trying a thing for school again. It's not #arduino but #adafruit #esp32s2 this time with #rfid . I am so noobish at this I was pretty sure I fried the board twice at least. Seems to be working though.

Did I ever show this? Turns out because #ESP32 has super-configurable pins AND because the #adafruit QTPy / #Seeed Xiao format has castellated pads, you can just solder an I2C OLED display right on top of it and it works! Since this is an #ESP32S2 #QTPy, I use this to test #CircuitPython WiFi stuff. Lately I've been using its as a Multicast UDP emitter 😀

Here's a slightly more complex (but I think really fun!) example using that 8x8 #NeoPixel matrix: an algorithmic MIDI music generator using colored "balls" that bounce around on screen, and when they hit the edge, they emit a MIDI note to a synthesizer. I like the result is kinda pretty sounding.
Thx @geekmomprojects for showing me these little LED matrixes!

#ESP32 #ESP32S2

here's the config sample for #ESP32S2, will probably work on #ESP32S3 too, #ESP32 wrover may need different pins though

#esp32s2 :flan_thumbs:​

Hello, I don't have one of these chips, but if you do and love #OpenBSD, please build and test this compiler and test out some binaries on chip.

Thanks! :flan_hug:

@e1e0, do you have one of these yet?
