DrBunsen Posted July 8, 2006 Report Posted July 8, 2006 Need more than +5V to trigger or power something? This little beauty from Sparkfun takes serial commands and can spit out up to 50 volts at 150mA continuous or 500mA spike.I'm cataloguing other intriguing parts on the Drumstuff wiki page Quote

DrBunsen Posted July 9, 2006 Author Report Posted July 9, 2006 for doing what??Well' date=' my Simmons drum module for example expects +7V for a full velocity trigger at the 5 pin sequencer input. It will trigger at 5V, but at a reduced velocity. My Roland System 100 from memory expects +12V or +15V. Other modules, especially home made or cloned ones, may expect a higher voltage too. It might also be useful for controlling high-current lights or LEDs in a MIDI controlled light show, or for those in the MIDIfication forum working on old organs etc.I also had this slightly insane idea for implementing velocity/accent in a drum sequencer by boosting the voltage to all the pins simultaneously. I think this chip could handle that.BTW, there´s also a TPIC6A595 version that can sink up to 350 mA/Pin continuous. Quote
