Cyril Posted December 31, 2002 Report Share Posted December 31, 2002 Hi!I always wanted to make a Midibox since I've discovered this site but I had no electronic knowledge at all. But the MBHP has simplify the system and I decided to try to build my own (with the help of some friends).I have two questions:1. Before the MBHP concept there was a contrast pot for the LCD module. Is it still possible to connect one and is it necessary?2. How can I connect a on/off switch to the power supply (J1 connection of the core module), and what kind of switch do I need (single pole/double pole...)?Thanks a lot for your response and sorry for my bad english (I'm french speaking...)!And Thanks a lot Thorsten for your great work and best wishes for the new year to all! :D Quote Link to comment Share on other sites More sharing options...
