MEP EP#252: Kicking Troglodytes Off The Stage

Parker

• PCB serial numbering or other unique marking
  • I have batches of boards and need to put some unique numeric identifier and a MAC address on each board.
  • Besides stickers, laser etching, scratching or DIY stencil and paint, what are folks doing?
• PinoTaur REV 3 boards arrived
  • REV 4 changes already ;)
• Ben Jordan of Autodesk will be a guest on the podcast
  • Product manager and is responsible for the EAGLE product
  • Get your Eagle questions in early!

Stephen

• Adventures in Rpi 4
  • Midi overkill
  • Clock master
  • Possibly be a usb midi device?
  • Reset?
• Repairs
  • Roland TR-606 drum matrix
    • Looks like a possible ram IC issue. The unit functions and does things that only a processor could do like blink leds at a particular rate
    • None of the buttons have memory - they do not “store” anything
    • Upd444c obsolete - 6514 SRAM is a drop in replacement
• The FX Dev board returns
  • 2 versions of the fx dev board now exist
    • ProtoBoard
    • Protis 1
  • Both look like they ditched my ac power supply for a charge pump design
  • Both opted to not do the integrated soldered breadboard
