All the devices in the cylinder would be using 5VDC, but the current power supply was 12V. It was a reliable source, but everything downstream would need to be brought down to a usable voltage. Most controllers have a puny onboard regulator capable of utilizing 12V, but the LEDs would require a DC-DC converter. Two were connected for this stage of the prototype, one for the controller which wasn't strictly necessary, and a larger one for the LEDs.
Regulators connected to terminal

The small regulator worked without any fuss after a screwdriver tuned in the voltage to less than 1% from target. Unfortunately, the one in the picture above was a step-up DC-DC module and wasn't useable in this case. It was swapped out for a beefy 5V 3A module with no adjustments.

A hole was drilled in the PVC where the LED strips could pass wires to the inside of the cylinder. In this version, the lights met to form a complete ring, whereas in the final version, they will form a helix, and the ends will not be close. Adhering the ends this close to each other created problems with digital lines getting close but it made it simple to connect the power leads to one another and ensure for even lighting at the beginning and end of each strip.

In this, and the final version, the cylinder will be mostly empty. A rod down the middle will be the only part that doesn't move with the pipe so there won't be much need to keep the few parts secured inside.
