This is a guide for all modern gentlemen who would like to show off their electronic prowess.
This illuminated pocket square is just the accoutrement to illustrate that you're more than a suit.
Despite your straight razor shave and that Steuben rocks glass you hold: You're a maker too.
Check out Draper 2.0 in action.
Step 1: Materials
For this project, you will need:
This is probably the first wearable electronics project that has plenty of space or a large battery, so feel free to be a little greedy. I found that 1200 mAh lasted for approximately three days of gluttonous use.
Step 2: Soldering the board
***The BAT, G, and 5V pins will already have headers coming from the bottom due to step one.
***Nail clippers are actually awesome for this.
Capacitor and wires
Be sure to pay attention to which lead is positive and negative on the capacitor.
This is optional, but also a good safety step.
This is shown as the green wire.
I used pin 6, but it's hard to see because of the battery backpack.
The strip will be attached to the opposite side and I had some issues where contact with the strip caused a short.
Step 3: Soldering the NeoPixel strip
This step is arguably the trickiest of business.
I'd like to share with you the best way I've found to reliably tackle this challenging step.
Tin the strip and the wires separately, then bond them.
Feel free to leave the ending pads on the remaining strand instead of splitting the tiny surface in half.
Be very careful to spend as little time in contact with the strip as possible.
It is relatively easy to ruin the surface mounted LEDs or melt them :X
Step 4: Tape Time!
Now it's time to attach the NeoPixel strip to the top of the board.
Even though the cloth of the pocket square will apply some diffusion, it wasn't enough to get a uniform 'glow' across the entire square.
Try using some foam tape thats usually used to mount photo frames on the wall.
I used the velcro-ish type to get a pretty even glow.
Step 5: Folding
Here is a great overview on pocket squares.
There is a ton of variation in folds, but the most traditional is the square fold.
In a square fold, it's common to place an index card to help the square hold its shape.
In our build, the index card is replaced by a battery and LED board.
Reference the photos above for a quick and simple fold that fits snugly into your coat pocket.
Step 6: Future Enhancements
There's still plenty of room on that Perma-Proto board to include some type of sensor.
Gentleman's Tip: Your pocket square should never match the pattern of your tie. Always aim to match the color of your shirt, or your date instead.
