Hi Arthur!Thank you for your comment and also for your great work on the display library! One thing that gave me confidence going into this project was knowing that I could drive the display efficiently using your library and have plenty of processor time left for the game (my coding is not exactly the most refined!).I did not know you were on Instructables or I would have linked to your profile - I'll do that now. If I make anything else based on this display, I'll be sure to let you know.Thanks again.Ugi
The green wire should be a high-impedance "sensing" connection, like an Arduino "input" pin so should not be any threat to your Ardu'.I put a 1K on that line out of an abundance of caution because that limits the current if there were any issues. However, it should be completely unnecessary.My only caveat here is that there are many makes and builds of ATX power supplies and although they should all conform to similar standards I have not made any attempt to test them widely. It is therefore just possible that _your_ ATX supply is different to those I have tried. I think the chances are very small, but if in doubt, put a meter on the pin, then ground it and measure the current flowing.Ugi
Great!Glad you enjoyed it and thanks for posting such a kind comment. Did you take a photo of your machine? If you did, post it and there's a 3-month pro-membership for you so you can look around instructables for other projects you fancy without all those annoying ad's!Keep up those projects!Ugi
Nice build. Hope it sounds good, 'cos it certainly looks it!I may have missed it, but do you have a sound post? That's the bit of dowel that sits under the bridge and braces the top against the bottom. It's the most important internal part of a normal violin for getting a decent sound. It also stops the top from collapsing under the pressure of the bridge.Your top looks narrower and stronger than a normal violin, but it's also flatter, where a violin gets some strength from being arched on the top and bottom. I would still expect that you needed a sound post both for strength and particularly for sound quality.Ugi
