The first thing you wanna do to build your own is to get all the parts. Please go to github and download the eagle files of the board. You can upload directly the design to Oshpark or send the gerbers to PCBWay, if you want to use another manufacture service you will need the gerber files. 

Now purchase all the parts, you can get it on Mouser, but be careful when selecting the size and the case style. Make sure everything is correct and in the right size, capacitor must be rated for 6v or more.

Optionally order the stencil, it will save you a lot of time and frustration when soldering. You can get one on Oshstencils or in PCBWay.

Apply solder paste to the board using the stencil. Now put the SMD parts in place, make sure to put it in the right way. Check where and how the parts go using the EAGLE board files. Then you can solder it using hot air or a reflow oven. Just be careful, it's pretty easy to make a mess with this tiny components.

Repeat for the other side of the board. This time use hot air and be careful to not desolder the components on the other side.

Now using a PIC microcontroller programmer (like the Pickit 3) burn the supplied firmware into the board. I used pogo pins to make the connection between the board and the programmer.  Check ICSP pin order on the EAGLE files or in the details section.

You can play making your own LED animations and sharing it with us :)
