EL wire drivers

EL wire is shiny but drivers on Aliexpress and probably Adafruit are bulky and noisy. There are smaller and silent ones though that are also less expensive. The only thing required is designed and ordering PCBs.

An off-the-shelf EL wire driver with tweezers shown on the side for later comparison.
The bottom of the same off-the-shelf EL wire driver as above; the potting to protect from high voltage and whining noise is visible.

My custom PCB acting as EL wire driver using an HV8xx chip which is roughly the same width as the off-the-shelf one but silent and ten times slimmer.
