This circuit could work, IF you swap around emitter and collector from what I could tell (have no means to test it here...). For a PNP-transistor to open, base has to have a lower potensial than the emitter, which it will not get in this circuit. JohnCox: If you haven't gotten any further, you could...

Re: GPO "connectors"
I'm looking for someplace that sells like, a 2 pin connector that fits nicely onto the GPOs and also a 10 pin connector that fits on the keypad. I'm not sure what they're called. Pin headers maybe? basically what you would find on the end of a computer power led to connect onto the motherboard. I w...

If all these drawings are correct, this circuit will not work (as you have found out...). The GPO in the drawing a couple of posts up, is basically an open-collector output, i.e. you need something to pull it up when it is switched off. Shorting the GPO, would do this and because of the limiting res...

I guess one of the other reasons are that the SDK is (I think) freely available, while there isn't any for MusicMatch... I also prefer MM, but without LCDC-support... :( I sent a mail to MusicMatch a while ago asking if they were planning to release a SDK (or if they would write a plugin for LCDC :)...

Finally had the time to make a board-file. As I said, it ain't pretty, but unless I have made any errors it should work. The top layer (red tracks) are wire links. The image-file wasn't very good, but it should be possible to use it. And they're seen from above. The .brd-file is an EAGLE board-file....

I think the reason the GPO didn't blow up is because it lasted very short. I had to put it to Fast Min/Max to catch it, otherwise it would only show about 0.22A. Min/Max needs a pulse of 50ms or longer to catch it, while Fast Min/Max can catch it down to 250uS. I was planning to check the duration o...

Tested with a Fluke 189 set to Fast Min/Max and it measured 4.9A peak! But the strange thing was that the CC stayed on. I used some longer leads to be able to measure this and also without the meter, the CC stayed on. Took off the extra leads and the CC just flashed again. If I put the longer lead b...

Installed the third CC yesterday and put it on GPO3 and had exactly the same result as Mask666. It came on for about half a second, then turned off. But it obviously drew too much current because at the same time the whole display dimmed. Hmm, guess I have to make some driver-thingy for it... :) Edi...
