I used a 1768 which I know is overkill. I want to port this to mbuino and put a small LCD or OLED on the mbuino. Suggestions for the LCD / OLED. I don’t want to spend a lot of money.
Thanks

Why not use a character display? They are very inexpensive.
@ DaddyOh - Nice post!
Also love the hat project you did for RVA Makerfest…very cool!
Very nice! GHI very graciously sent me an mbed board (Medusa Icon), and I can’t wait to dive in.
Be careful measuring at 20k RPM, though. Things spinning that fast tend to fly apart, and then stuff gets exciting!

@ DaddyOh -
What are those mounting plates you’re using? Mechano?
@ godefroi
They are actobotics parts. I love them. A little $ but you can build a lot. Have a look at http://www.servocity.com/html/actoboticstm.html
