Different to the flash drives, this needed buttons and a headphone socket. Plus an annoyingly large battery.
Step 1: Materials and stuff
I also needed:
- Four lego bricks (two 1x4s and two 2x4s) and several lego "plates" i.e. flat pieces for the base
- Super Glue
- Hot Glue
- A mini drill or similar for sanding down / cutting up the bricks
- Sand paper
- A solder iron and solder
- Good lighting helps
Step 2: Get player circuit and start on case
After looking at the board I realised I could either go for making the case four dots wide and be on the safe side, or three dots wide and need to do a bit of squeezing. I went for three.
It was fairly pain free to glue the bricks together and hollow them out. For the sake of getting the circuit in easier I kept them in two parts. Note that super glue was what seemed to be the best choice here, the edges were mearly a milimeter thick, and it needed to be strong and accurate.
