1

Step 1

Cut a suitable size of stripboard.
2

Step 2

Cable-tie the LED string to the wheel chair's frame, and duct-tape the controller and power bank somewhere handy.
3

Step 3

Tweak the design to give whatever patterns you like!
4

Step 4

Solder on the pin headers so that they mate with the FPGA board's outputs
5

Step 5

Solder on the current limiting resistors close to the pin headers.
6

Step 6

Use the left over wire from the resistor legs to make jumpers, used to join the tracks together, combining currents.
7

Step 7

Attach the screw header to the center of the stripboard.
8

Step 8

Cut the strips under the resistors, and all strips between the legs of the screw terminal block.
9

Step 9

Check that the strips with a multimeter to ensure are really cut where they should be. Also ensure that their is no continuity between contacts on the screw terminals.
