The el controller that came with it has slow and fast flashing modes as well as always-on, which are very effective and give that neon sign feel. I hope to hack a vu meter kit soon to make one of these that pulses to music, great for the festival season.
Step 1: Raw Materials
Next a cassette tape - I picked up a 3-pack of new tapes for £1 at the car boot, which saved a trip into the loft and spending hours deciding which precious mix tape to sacrifice.
With the cassette dismantled and the tape itself discarded we're ready to start making, superglue at the ready!
Step 2: Routing The EL 'Tape'
You need to cut a hole for the power cable, then decide where to start wrapping the wire around the reel. It's easiest to glue the reel to the cassette body first, then stick the el wire to it bit by bit.
With a turn or two on one side it's time to route the wire through the cassette body to the other reel. Unsurprisingly el wire is thicker than magnetic tape - I found it easiest to cut small bites out of the cassette body with a rotary cutting tool to make sure the el wire followed the same path as the tape but would still allow both halves of the cassette to close fully together.
