That’s it! It was a lot of tedious work, but not very many steps. To make them a little more sturdy though I would recommend sewing as well. I had intentions of sewing them on, but ended up hot glueing and they stayed on just fine. The reason I placed it with the backside up is so that the breast pocket would be in the back to hold the trinket and battery pack. I then placed the undershirt backside up beneath the shirt with the faux leather pieces and started to line up the neopixels on it. Once they were all pieced together, I added hot glue to the solder joints to make them a little more sturdy. This took a bit of time because there were so many solder joints and one needs to make sure the input and output are in the correct direction through the chain. Once I had them all laid out, I had to run wires to solder the connections back together. Then I laid out the neopixel strips, cutting them to length. First I took the outer shirt and placed the laser cut pieces of faux leather on in the correct orientation. The hardest part of this project was getting everything lined up. The Lithium battery pack I chose had over 6Ah which was more than enough capacity for the time frame I needed the shirts to run.
ADAFRUIT TRINKET ANALOG INPUT PRO
To enable the use of a rechargeable battery pack I soldered the Pro Trinket Lithium IonBattery Backpack to the Trinket. I used a Pro Trinket 5V version to program the neopixels. the 60 LED strip, I was able to see each individual LED through the shirt with the 60 LED strip which wasn’t the look I wanted. The reason I chose the more densely populated strips is because when I tested those vs.
ADAFRUIT TRINKET ANALOG INPUT FULL
I used almost two full spools of 1M long neopixel strips that each contained 144 LED’s. Let’s start with the electrical components. As with any project, there are a hundred different ways to create this, but these are the steps I took to complete the project. This blog will include the Vector files needed for laser cutting the black material, program used to control the NeoPixels, and full bill of materials. Ever been tasked by your employer to create a Tron shirt for a dog? Well I have, and it was definitely a fun project to break up my daily tasks.
