rune_sm Posted August 21, 2006 Report Share Posted August 21, 2006 Hey everyone.. I have searched for 2 days, but can only find 1 unsufficient thread about this...But Im building 1 Core module, 1 AIN module and 1 DIN module into my guitar. I will make a midi-jack beside my regular jack to send out midi signals to my guitarpedals.I want to run the power over the 2 unused dims in the Midi-cable. The power has to run the modules + 20 blue LED lights running 3.6 volts each (20ma). Which poer supply should I use, which dimms are the unused in the MIDI-cable, and how do I run the power inside the guitar (do I just split the wire into two, one going to the modules the other going to the LEDs?) Thanx - Rune Quote Link to comment Share on other sites More sharing options...
Screaming_Rabbit Posted August 21, 2006 Report Share Posted August 21, 2006 I want to run the power over the 2 unused dims in the Midi-cable... I think you mean "pins"...? Just use the left over onesPins 4,2 and 5 (the three middle ones) are occupied by the MIDI interface by specification.and how do I run the power inside the guitar (do I just split the wire into two, one going to the modules the other going to the LEDs?)... I think you got something wrong here: The MIDI cable is the connection to your synth (or the DigiTech pedal... I think you're the guy writing about this stuff in an other thread). So you'll have the core board in your guitar and the buttons and LEDs are connected to it.Greets, Roger Quote Link to comment Share on other sites More sharing options...
rune_sm Posted August 21, 2006 Author Report Share Posted August 21, 2006 Hey... Sorry I didn't explain it so good. The 20 LEDS are seperate from the whole midibox thing... They are connected to an on/off switch just for lighting the beast up, and have nothing to do with the core... That's why I wonder if I should just split the power coming from the midi-cable in 2? Or will the seperate LEDs pull too much power??Thanx for helping.... i'm learning alot :-) Rune Quote Link to comment Share on other sites More sharing options...

The splitting shouldn't be a problem... it's like you're having 20 "power ON" LEDs ;DFor the cable I think it's no problem as well, even thought those single lines aren't of large diameter.Greets, Roger Quote Link to comment Share on other sites More sharing options...
sneakthief Posted August 22, 2006 Report Share Posted August 22, 2006 before you go crazy when trying this out, make sure that the midi cable you're using has all 5 wires! most midi cables just have 3 (plus ground).cheers,michel Quote Link to comment Share on other sites More sharing options...
rune_sm Posted August 22, 2006 Author Report Share Posted August 22, 2006 Thanx man.. I could just see myself running around in circles when trying to solder the wrong cable :-) Quote Link to comment Share on other sites More sharing options...
Steven_C Posted September 1, 2006 Report Share Posted September 1, 2006 Out of interest, at least one TC electronic midi system (remote controlled graphic equalisers) that I know of uses all 5 pins on midi. I can't remember what the extra two pins were used for. As usual I'm too tired to think. (Got a head full of study :P) Quote Link to comment Share on other sites More sharing options...
cimo Posted September 3, 2006 Report Share Posted September 3, 2006 hi runerunning voltage on MIDI cables has its own protocol and it is 7 pins MIDI plugs where the power supply is connected to pin 6 and 7i advice you to stick to this for future use with other hardware (you may have a look at the DSP "Eclipse" from Eventide) and also because as mentioned some hardware (yes not really commonly) uses pins 4 and 5 and you don t want to burn that kind of hardware !!good lucksimone Quote Link to comment Share on other sites More sharing options...
