Hi all,
It's my 1st post and I'm almost totally green to most electronics.
Right now I'm trying to make a Bob Beck electrolysis device.
It calls for three 9v batteries in series to produce 27v.
He also says to use a 30v Grain of Wheat bulb as an indicator light, also placed in series.
I haven't been able to locate a 30v GOW bulb.
I'd prefer to use a 30v LED, but can't find one of those either.
If anyone knows where to find either of those lamps that'd be great.
In the mean time I have a Q about a work-around.
I've taken a 3v LED and placed it in series with a 12k ohm resister.
so...
1. Is that about the right size resister?
2. Will this setup still give 27v for the electrolysis?
