E6000 requires hours to reach full strength. This is an excellent time to take a break or stop for the day. Put the pieces in the garage or out on a balcony while the glue dries…the fumes aren’t healthy to breathe. Turn off the soldering iron, wash your hands because you’ve been handling all this stuff, then go to bed, go for a bike ride or have a Pop-Tart®.
We’ll continue below. In the meantime, here’s another picture of Erin “Firepixie” spinning POV-poi to keep you motivated:
The moment of truth!
You should have already loaded the poi sketch onto the Trinket microcontroller(s). If not, skip ahead to the “Code” page for a moment, fetch that software and program the boards.
If the LEDs don’t come on, here’s some things to check…
Green power LED on the Trinket doesn’t light with the power switch in either position: disconnect the battery immediately! It may be an electrical short between + and ground. Connect a USB cable between your computer and Trinket. If the light comes on then, it’s probably not a short, just a spent battery. Re-connect it and allow some time to charge.
Green LED is on, but the LED strips do nothing: connect a USB cable and make sure the poi sketch is loaded on the Trinket board. If there’s still no response, probably a wiring mistake…either the clock and data wires are reversed, or they’re connected to the wrong pins on the Trinket (should be pin 1 for data, pin 2 for clock).
Only one LED strip is active: wires are probably in the wrong order on the unlit strip.
Power switch won’t budge: glue has seeped inside. Use more force to try to break it free. If it’s completely wedged, there’s no choice but to break it down and solder in a new switch.
Power is always on, switch does nothing: on the LiPoly backpack board, the copper trace between the power switch connections has not been cut.
Once any issues resolved and the LEDs are doing things as expected, switch it off for the final assembly steps…
