Trinket 5V
The Trinket 5V micro-controller runs code that will animate the NeoPixel Strips and NeoPixel Rings. The Trinket has enough memory to power about 100 NeoPixels. To power the Trinket, we'll use a lithium polymer battery. Most of our lithium polymer batters have JST connectors. The Trinket doesn't have a JST connector on board, so we'll have to solder one on!Tin Trinket
Secure the trinket upside down to a panavise jr or third helping hand. This helps you tremendously while soldering! Add solder to the +Postive and -Negative pads on the back of the Trinket, right below the USB port.Trinket JST Connector
Measure a JST extension cable to about double the length of the Trinket and cut the cable. Use wire strippers to strip the ends of wires with the female JST connector. Solder the positive and negative wires to the bottom of the trinket where the positive and negative pads are tinned with solder.Prep Trinket + Jumper Cables
Add a bit of solder to the GND, BAT, and #0 Pins on the Trinket. Grab three female jumper cables and snip off one of the ends. Use wire strippers to expose the tip of the wires.PowerBoost 500C
The power boost 500C will provide enough current to power the NeoPixel strips and rings. We can get about 100 NeoPixel LEDS to animate properly at full brightness. The Powerboost 500C also has an on-board lipoly charger so you can recharge a lithium polymer battery over USB.PowerBoost 500C JST
Grab the other half of the JST extension cable with the male connector and strip the negative and positive wires. Solder the wires to the +positive and -negative pins on the Powerboost 500C.Slide Switch Wires
Measure and cut 3 strips of stranded wires to about 30mm in length. Expose the ends of the wires using wire strippers.Solder Wires to Slide Switch
Secure the slide switch to the panavise jr. Use a third helping hand to hold one of the wires up against one of the terminals. Once the wire and the terminal are secured and touching, add the soldering iron to the terminal and solder it while they're both in place.Shrink Tube Slide Switch
Seal off the soldered connections by slipping on some pieces of heat shrink tubing. Just add heat to shrink!Install Slide Switch
Bundle the 3 wires and thread them through the slide switch opening in the enclosure (trinket-box.stl). Carefully fit the slide switch through the opening and snap it into place.Secure Slide Switch
Add some E600 to the top ands sides of the slide switch to permanently secure it to the enclosure.Solder Slide Switch Wiring to PowerBoost
With the slide switch installed to the enclosure, strip the other end of the 3 wires and solder them into the PowerBoost 500C following pins.EN, GND, VBAT
