Cute -- BUT!

Novel concept, but not really able to survive an ESD event of which there will be many.

I remember building a Sinclair ZX81 look-alike in the early 80's and while writing programs it would periodically crash.

It turned out is was the ESD zaps on the keyboard which was a printed mylar/alu laminate, and more rugged than this, yet it had problems.

I am quite curious if ESD has much effect on this. I know the capacitive buttons are a bit sensitive, but I wonder if the system as a whole gets messed up.

Hello!

Kevin Bates here, maker of the Arduboy! Thank you so much for covering this Caleb, I enjoyed your previous writing at your old outlet!

The microcontroller has very good built in protections on the input pins. It is surprisingly rugged. I have kept it in my wallet for a week now without any problems.

In fact I will probably post a video of me rubbing it on a carpet or some such thing. I'm interested to see how far it you can push your luck.


On the more reasonable side of things, it's probably a good idea to put some polyamide tape or some other kind of insulating material on the back of the card. I have plans to offer vinyl stickers with different designs and of course also the files you need to make stickers of your own!

@Kevin: I LOVE it -- I want one!!! Are you planning on launching a Kickstarter project to crowd-fund this? EE Times blogger Duane Benson and I are in the process of launching our own Kickstarter project -- email me at max@CliveMaxfield.com if you have any questions.

Yes, hopefully a kickstarter in the next few weeks. I am trying very hard to find a manufactruer to mass-produce these. It will mean I don't have to limit production of assembled units and the overall price will likley go down. But no promises, this board has to be hand assembled so I've already had a board house decline to bid.

Yes I think I recieved your email! Keep in touch!
