3D Printed LED Bracelet With Motion Sensor
Intro: 3D Printed LED Bracelet With Motion Sensor
This project started when I printed Diagrid Bracelet by nervoussystem and got the idea to add some LEDs to it. I designed the model using123D Design. An Adafruit trinket (Attiny85) is controlling a Neopixel 144 LED/m strip and reading value from a FLORA Accelerometer/Compass Sensor (LSM303) using I2C.

STEP 1: What You Need
- Trinket - 3.3V Logic
- 144 LED/M Neopixel strip
- Smal battery (~110 mAh)
- Neodymium magnets (3 mm)
- FLORA Accelerometer/Compass Sensor - LSM303
- 3D printer
- Soldering iron
STEP 2: Model
Download the files from Thingivers http://www.thingiverse.com/thing:248567
I printed it on a Form 1 using white resin.
Print the model and glue the magnet.
STEP 3: Electronics
- Trinket - 3.3V Logic
- 144 LED/M Neopixel strip
- Smal battery (~110 mAh)
- Neodymium magnets (3 mm)
- FLORA Accelerometer/Compass Sensor - LSM303
Connect the led stripe to D1 to one of the trinkets pins, I use pin 1, and connect +5v to the battery positiv and GRD to negativ. To connect the accelerometer use pin 0 for SDA and pin 2 for SCL.
STEP 4: Code
Software
STEP 5: Party!

would be great if you could send me a better pic how you connected every wire. I cannnot really see the connections... how did you connect the battery with the trinket or led with trinket? Thanks!

Hi,
I have done some changes to the design and added a power switch to the trinket. I have some pix on that in this blog post http://www.slickstreamer.info/2014/07/led-bracelet-vu-meter-3dprinting.html . Hope it help otherwise I can take som more photos.
