Once you're sure that everything is working, it's time to secure your connections.
- Put a dab of hot glue over the LED solder joints to keep them from popping off if your poi get a good whack.
- Glue the battery charger to the back of the Teensy with a big dollop of hot glue (enough to ensure they don't touch and short each other out
- Wind the wires to the IR sensor around the teensy and glue in place near the bottom end of the teensy (away from the USB port) with the bump on the IR sensor facing out
- Glue the Teensy down to the top of the wooden dowel. I used a liberal amount of hot glue so it stays firmly upright.
Once everything is secure, carefully slide the whole assembly into your polycarbonate tube. I found it easiest to start with the Teensy end, since the battery end was a pretty tight fit.
Once it's inside, fit the bottom cap over the power switch. Make sure the switch is accessible and works nicely, then glue the cap on using E6000 glue (or your favorite acrylic glue).
If you haven't already, thread your leash through the holes you drilled at the top of the poi and secure it. Turn it on and give it a twirl!
