nogginj Posted August 31, 2004 Report Share Posted August 31, 2004 hey guys. I started the midibox plus almost 2 years ago and am just now REALLY trying to finish it. My question is...I bought the PCB from mike's site. I see it matches up to this gif - http://www.ucapps.de/midibox/mplus_pcb_v1.gifIf I follow this exactly, even though it it is somewhat different than the old schematic, will it all work??ALSO, there are two boxes on there that I have no clue what they are. towards the bottom of the gif, right above the connection to the lcd screen...they seem to connect to three points and on the photo they look like two black boxes. what are these?THANKS!

raphael Posted August 31, 2004 Report Share Posted August 31, 2004 Hi,If I follow this exactly, even though it it is somewhat different than the old schematic, will it all work?? I think with the "old" schematic you mean the 8 pot version.Mikes PCB is the 16 pot version and here you can find  the "new" schematic (which works for sure ;) ):http://www.ucapps.de/midibox/midibox_plus_16.pdfALSO, there are two boxes on there that I have no clue what they are. towards the bottom of the gif, right above the connection to the lcd screen...they seem to connect to three points and on the photo they look like two black boxes. what are these?This are 2 10kOhm Trim-pots (variable resistors) for adjustment of brightness and contrast of the LCD.Raphael Quote Link to comment Share on other sites More sharing options...
