This is a very quick update. 

20 PCB's have arrived from China which I can solder the microswitches to and also 2 rows of pin headers to allow the Teensy board to be plugged into the FRONT of the DigiGurdy. 

The whole machine will be white as in the left-hander featured in Project Log 12b.

The Teensy will have a small 3D printed removable plastic cover. This allows it to be unplugged and sent to me if not an Arduino enthusiast so I can mail it back to you with a software upgrade.

It also allows an SD card to be slid into the end of it, should I wish to use that for something - working on it. For those who have suggested I design a custom board with WiFi connectivity for software upgrades, my answer would be that to do that I would have to employ someone and unless making 1000 of them, not much point. As it is I paid someone to design this PCB.

It does speed up the build time considerably and is much neater.

Other project taking up 99% of my time right now but I thought I would put one of these together just to check that it works - which it does.

Photos below, just the electronics assembled for testing purposes.

The USB lead will be held captive in the slot cut for it by the cover which will enclose the Teensy and this cable.

Fantastic. Would you consider selling some made, or kit, in the future? I intend to perform with your Digi-Gurdy and Techno Bombard (Aodyo Sylphyo). If not can you recommend a starter hobbyist 3D printer suitable for this project? I have been following this project for some time, hoping you would integrate a crank. Many thanks.
