I had this hissing sound too :(
And my laptop went dead when I plugged in the USB..
Hi, hissing sound is normal, but maybe the output of your laptop is too low for your EL load.
Is the hissing sound normal when plugged in?
Sorry for the late reply, it is normal.
Is there scheme of USB EL Inventor or Open Source project like this ?
I bought 3х EL Panel - White 10cm x 10cm but forgot to buy invertor.
and the expectation of the parcel - for too long,
it is easier to do it myself. Thanks! ^v^
Hi Andrew, glad to know your interest in this product, unfortunately, it is not a open source product, schematic is not available.
I plan to install this EL wire in car, can this inverter take in 12V DC
Hi,12v may not.
If the order is in production, then don't cancel it
In input i must have 5V or more?
Dear Matteo.More or less is ok.
just it was unusual, status"PCB processing"don't change to"In production", immediately to"Shipped".
