Assembly notes:

  • Click on the image below and use the arrow keys to scroll through steps. Directions will hover above the image.
  • Careful not to overtighten M3 screws. Acrylic can be somewhat brittle.
  • If you laser is accurate enough you may be able to get away with sizing the holes exactly and not drilling them out. This is probably possible with ponoko but not my local FabLab epilog.
  • It’s fun to use other colors of acrylic but clear is sure nice to verify pin alignment.
  • If you have questions or ideas for improvement send them to info@tinylabs.io!
  • Package from ponoko!
  • Panelized parts
  • Break parts out, careful not to lose spacers to latch!
  • Insert hex nuts in panel (orientation should be flipped compared to PCB).
  • Flip over and insert front and back vertical supports.
  • Insert side vertical supports.
  • Mount top head panel.
  • Fasten top panel with M3 screws, don't over tighten. Hex nut should be flush with bottom panel.
  • Using #50 drill bit carefully drill out holes to size.
  • Remove 4 M3 screws to disassemble head.
  • Clean both sides with isopropyl alcohol and gather pogo pin receptacles.
  • Push each pogo pin through the base of head. Opening should point towards PCB.
  • Should look like this when completed.
  • Align top over pogo pins and slide back on.
  • Re-assemble head, pogo pin bases should be flat with bottom.
  • Slightly push out pogo pins you want to connect with PCB first. In this case GND then VCC.
  • Apply glue to base of pogo pins (on top surface only!).
  • Put aside for glue to dry...
  • Lay out components for base.
  • Insert cross supports into one side.
  • Mount other side on top.
  • Mount M3 screws into one side with captive hex nut. Leave screws a little loose.
  • Flip over.
  • Mount other side with M3 screws and captive hex nut. Leave screws a little loose.
  • Add support panel (outline should be smaller than pcb). If it doesn't fit loosen screws from previous steps.
  • Add PCB capture base.
  • Attach PCB capture screws and tighten all side screws. Careful not to over tighten.
  • Lay out hardware to mount head to base. Hopefully you haven't lost the spacers...
  • Put M3 screw through hinge and spacer on each side.
  • Mount head and push M3 all the way through. Use captive M3 nut to complete hinge.
  • Completed head and base. I did this out of order which is why the pogo pins are missing... Add latch to either side.
  • Solder on header to pogo receptacles. I added some heat shrink too but it's not necessary.
  • Completed fixture with all pogos and headers to connect.
  • Push all pogo pins into pogo receptacles.
  • Completed fixture! Added homemade wiring harness to connect JTAG/UART/power.
