Sasha Posted June 12, 2007 Report Share Posted June 12, 2007 Hey guys, check out this memory potentiometer based on PIC16F81. It could be very useful for applications with sensors or resistive touch pads.There are Eagle schematic, PCB and code available for download. :) http://misusage.org/wordpress/?p=19 Quote Link to comment Share on other sites More sharing options...
audioworld Posted June 12, 2007 Report Share Posted June 12, 2007 ...I also just discovered it via matrixsynth and wanted to post this.-))yes, very nice, especially because the pic file is short and easy to read, the circuit could be build with verowire in one hour I suppose..useful!

brocca Posted November 15, 2007 Report Share Posted November 15, 2007 Sorry to dig up an old topic. I'm building one of these and its great. Was just wondering there is a midi equivalent/implementation that I could use were I to build a midibox. I use midi motion sequencing a lot with an old korg groovebox but the midi transfer responsiveness is pretty rubbish.Suggestions? Quote Link to comment Share on other sites More sharing options...
bill Posted November 16, 2007 Report Share Posted November 16, 2007 hmmm, those DS1267 looks very interesting It must be possible to do some pwm with this and a ne555, then drive servomotors with mios... So, no one tried yet ?I'm going to buy one or two of those chips ::) Quote Link to comment Share on other sites More sharing options...
bill Posted November 16, 2007 Report Share Posted November 16, 2007 ouch, but they look pretty expensive :-\ (5,73 € on farnell)http://fr.farnell.com/jsp/search/browse.jsp?N=0&Ntk=gensearch_004&Ntt=ds1267&Ntx=&_requestid=37183 Quote Link to comment Share on other sites More sharing options...
brocca Posted November 19, 2007 Report Share Posted November 19, 2007 argg you're right :'( this is not going to be practical to apply to more than one or two pots.maybe I should move this to design concepts. I'm a real n00b but finding a way to use this much loved feature would make me very happy. Tried hunting round an ea1 pcb but my chip spotting is hopeless...doh if only I wasn't so new to this.
