The Human Glowstick – Part 1

As I know there was a significant interest in my costume this year, I am going to try and put together all of the directions on how I both constructed the foam exterior to the costume, and hooked up the 338 LED modules + Teensy + Bluetooth LE + SPL meter electronics to make the costume what it was.

As a first post, I will provide you with my electronics shopping list (that made the final production), getting into the foam in a later post.

Shopping list:

  1. Two 12V/20A DC regulators for powering the LEDs
  2. One 5V/3A DC regulator for powering the electronics
  3. Two Turnigy 4S 5000mAh 25C LiPo Batteries
  4. Two HXT LiPoly Battery Monitors for 4S packs
  5. Two 4mm HXT to 6x3.5mm Bullet breakout cables
  6. Ten 3.5mm Bullet Extension packs (pack of 3 wires)
  7. Eight pairs of 4-pin JST SM Plug/Receptacle Cable Sets
  8. One pair of 2-pin JST SM Plug/Receptacle Cable Sets
  9. Ten feet of 12AWG Silicone Wire
  10. Two 4mm HXT 10cm Silicone Wire extensions (battery side) - would actually recommend NOT using the same for battery/ESC...
  11. Two 4mm HXT 10cm Silicone Wire extensions (ESC side) - would actually recommend NOT using the same for battery/ESC...
  12. 400 (only used 238) WS2801 12v 4xLED modules
  13. One MOSFET power Control kit
  14. One SparkFun Sound Detector
  15. One Bluetooth LE (nRF8001) module
  16. One Teensy 3.2 (32-bit ARM processor) Microcontroller
  17. One 74HCT245 bus transceiver chip

 

Additional but unknown quantities:

  1. Rosin-core solder
  2. Solder-wick
  3. Solderless breadboards
  4. Jumper Kit
  5. Heat shrink tubing
  6. Zip ties (6 inch & 12 inch)
  7. Resistors of various values (for tuning mic sensitivity)

I will try to go step-by-step with the directions as soon as I can, but I hope this starts you off with a "big picture" of how much time/effort/money is involved in such a project... really that is it though, cause most of the difficult things have been taken care of by using "off the shelf" modules from people like SparkFun & Adafruit. 🙂
