Hero999 Posted April 29, 2012 Report Posted April 29, 2012 All right, I'll respond.Where's the code and a detailed write-up of the project?Your soldering is horrible, especially the two LEDs dangling off the end of the board.I notice you're using Q1's base current to drive another LED, is that to save power?What does D1 do?Finally why are you here? You seem to be more interested in publicising your site than anything else. I've not pressed the delete button because your projects are interesting and on topic but just you let you know, you're on my list of potential spammers. Quote
