Here's what I've been up to lately. I wanted to participate in a Hackster contest, but missed the deadline due to lots of problems, but now it plays. I still need to attach a vacuum cleaner to handle the pumping. And I need to decide on the final setup for the user interface. It started as an Avr-Iot WG project. Then I lost the board and couldn't find it anywhere. Right now it has a MKR 1010 Wifi and it looks like the final setup will be a laptop playing midi over Wifi to the MKR 1010.
  • 1 Arduino MKR 1010 Wifi
  • 4 PCA9685 servo drivers
  • 61 hobby servos
  • 2 LM2596 voltage converters
  • 1 12 V lead battery
  • Carpenter Reed Organ from 1902


Still 3 unused servo ports, as well as some pins on the MKR 1010 itself. I'm going to add some sound control (pulling organ stops, lifting lids for crescendo and diminuendo...)

Somehow I couldn't get the MKR 1010 to find my midi stream over Wifi, so I switched to Sparkfun's ESP8266. My present version works as follows. I have sheet music in MuseScore on my laptop. I have rtpMIDI installed on the laptop. MuseScore plays the score and sends midi to rtpMIDI, which sends it via Wifi to the ESP8266. The organ plays the tune. Any tune I write or download from MuseScore.com, as long as I change the instrument to Harmonium or Reed Organ. Some restrictions, though. A 16th note is the shortest in standard tempo 120 bpm. And even quarter noter are hard, if same tone is repeated. I have to shorten them to dotted 8ths to give time for key to come up before going down again. But it works great! A big challenge would be the Flight of the Bumble Bee. It might work with a bit of arranging and single note editing. Where same tone is repeted rapidly, I'd change it to octave tremolo.
