Arduino Shield

Components needing hand soldering are:

  • 3 MALE DSUB 9 Plugs for Current Source/Triggers/Switchboard - Farnell part number: 1084697
  • Mini Din 8 Socket for Phase Marker connection - Farnell 243-1942
  • All the Headers - 0.1'' or 2.54 Molex Vertical Breakaway - I bought loads of long strips and cut them to size - Farnell 165-4535
  • DC-DC converter - IK0512SA Farnell 1859047
  • Stimulator Out - Right angled 2way molex kk type farnell 1756797

Kludges

Position of CS Dsub is above DC Socket on the Arduino Due, but there isnt enough room depending upon which Arduino Due you are using (different manufacturers use different parts). So I have had to trim the wires from the dsub after I soldered them, and file down the DC plug, to make the board sit flush

Trigger Cable for Biosemi

Output from board is 9 pin suitable for actichamp, but Biosemi is 37 pin. BioSemi Pinout. I made an adaptor cable by cutting a serial cable off at one end, and soldering the wires to a solder back 37 pin connector (like Farnell No 1084675) and putting into a housing. The page here was useful in checking the colours of the wires inside the cable. Pins 1 - 8 Connect to 1-8 of the 37 Dsub, but pin 9 (GND) connects to pin 37.

Making a new ground cable means you need to connect using the pinout here

SwitchBoard

Components for hand soldering:

  • Switch for the board is SPST Farnell 678132
  • Battery Connector for board - SMT one is farnell 9492615, and the battery side is 2mm is farnell: 3616186. This is the same as the adafruit charger PowerBoost500, which I thought was a standard, but you will have to make the plugs with 2mm
  • Daisy Chain out is : 1 MALE DSUB 9 Plugs - Farnell part number: 1084697
  • Left hand side - Ard in and Daisy Chain in: 2 FEMALE DSUB 9 receptacle - Farnell number 8391289 CN11152
  • Bottom EEG 37 Dusb - Male FN 2401239
  • Top EIT 37 Dsub - Female FN 8391394 or 1848375
  • Micro Usb - I hand soldered the 1st and 5th pin only (so it only charges) Farnell 2293836
