Pulse Choker Hack Notes, July 8th, 2009

  • we found 4 different LED/phototransistor parts which would make suitable sensors
  • we found axial LEDs
  • ordered both of above from digikey
  • tested epoxy job on sm led from last time - still quite weak (but much stronger than crimp bead effort)
  • new epoxy job on radial LED legs, with more surface area we're hoping for a much stronger bond. If this works, axial LEDs will be perfect.
  • also trying sm epoxy again

Found a series of useful webpages on sensing heart beat:
