Hello! Testing my new Arduino Mega powered hand and mechanics using code from my other hand ( https://www.youtube.com/watch?v=t52edTD9RA0 – Part 1) – a few kinks to iron out in both the hand and the code 
I’m using regular micro servos as waiting for parts for my custom 3D printed actuators – I assembled and tested them a week ago and discovered an annoying design flaw!!! Anyways, thought I’d cobble together a few servos, double sided tape and the old code (with a few adjustments) and see what the hand can do.
Not all functionality is working as I’m not using the actuators, but you can see the basic movements.
10 pound fishing line as tendons, dodgy wall anchors/toggles as spring loaded knuckles (wont use them again!), but all seemed to work well with the first few tests…
Anyways, I think I’ll move on to the next stage and instead of designing and making every part using pencil drawings and calipers, I’ll design the entire hand/fingers/mechanics using good CAD software. The actuator housings which I did design using CAD and had 3D printed are good and functional (once ready), so the rest of the hand can be too!
Stay tuned for part 3 – refined evolution!!!
Thanks for watching!
