Playable electronic modules - modules in action

Did some testing with the SN74HC14 on a breadboard.

Going to the ON state is delayed by 15 ms, going to the OFF state with some 25 ms.

I did same rapid pushes on the button to see if everything was registered, and it was.

So for human/kid interaction this is fast enough. For automated systems it might depend, but in that case better switches and the proposed latching method might be a good idea. My pushbuttons are probably of the worst kind: leaving the speed of closing/opening the switch up to the user. Better switches will be of the click/clack kind. Where some tension is build up and then released going into a different state much faster (like the toggle switch). Also better contact materials (gold) will give better results, but were on a budget

Two of the new revision modules are ready!

Surface mounting the IC's "my way", takes to much time so, I'll will order some of these. It makes the modules 50% more expensive, but I think it will be well worth it.
