  • Connection wiring (3x 4p JST-XH for display I2C, 1 7p JST-XH for keypad)
  • Square keypad LED lenses (2x white, 1x red/amber/green)
  • Small 4ohm 3W speaker
  • Display stickers

For orders with 3d printed parts or aluminum enclosures, you should have the following:

  • 3x inner display enclosure (silver/aluminum)
  • 3x faceplates (silver)
  • Keypad (Olive green – smooth on top)

What You'll Need to Assemble Your TCD Kit

  • Phillips head screwdriver
  • Thin double sided tape for adhering display gels to display faceplates, and then to display enclosures
  • X-Acto Knife or sharp scissors to cut out faceplate sticker labels
  • Flush cutters like these, or a 2.5mm (3/32") drill bit to take the keypad apart
  • 3mm (1/8") drill bit to cut holes for the 4 AM/PM & Hour/Min LEDs in the display gels
  • Cordless drill
  • A power supply with at least 1000mA output. The TCD can be powered by desktop computer USB, or something like a phone charger with a Micro USB to USB cable. It can also has an on board power supply via the green connector that can accept DC power between 6-20V.

If painting 3d printed parts: There are various methods of smoothing 3d printed parts, but the following is for the old fashioned fill/sand/paint method.
