MAKE contributor Michael Una posted this vid documenting a triggering problem he ran into while developing his homebrew sequencer. The project, based on a 4017 decade counter chip (which are awesome, btw) benefitted from the addition of some PNP transistors. Though he doesn’t mention exactly how the fix was implemented mayhaps he used them in conjunction with that LED signal to gate those triggers. [via GetLoFi]

  1. Yeah, I need to post some diagrams. Suffice to say, Collin’s right- I used some PNP transistors to gate the signal that triggers the sounds. Sorry everyone- drop me a line if you’d like to learn more.
