Whew! Anybody is through
with the technical stuff: now it is time to have some fun designing the
lights! The goal was to make the pathlights easy to build and use readily available parts. Anybody uses PVC pipe, old pop bottles, toys from the thrift store, short pieces of clear tubing, clear packing tape, copper wire, and enamel spray paint. The LEDs are stuck in the end of medium-weight speaker wire. Clear plastic tubing is shoved over the LEDs and taped in place. This helps to hold the LEDs straight inside the pop bottles, and also the tubing helps to disburse the light from the LEDs. The old IBC pop bottles just happen to fit snuggly inside the PVC elbows. Heavy clear packing tape is used to seal up this connection, and then copper wire is wound around the bottle to prevent the tape from coming off. The LEDs' speaker wires are run up inside the PVC to the container with the circuit, batteries and Solar CD: they are connected to the circuit with twist-on electrical connectors. |
