DIY static grass applicator
« on: May 28, 2020, 03:12:58 PM »
I have just made a SGA from one of those tennis racket bug swatters and a metal tea-strainer.  It currently (no pun intended) is powered by two AA batteries.  Having a root around my bits and pieces, I've found a 4.5v 1500mA wall wart (an old phone charger I'm guessing), with a 2meter lead on it.
Do you think I would be able to utilise this to power the SGA, or would it be too much and blow the electronics in the swatter?  TIA
Cheers, Trev.

Very possibly - it's 50% higher voltage that they are designed for and since those zappers are so cheap I doubt they've got much, if any, overvoltage protection built in.
