[time-nuts] the end of light bulbs as we know it was Re: Safe power-up. was (Solartron 7075 ...)

[Neville Michie]

Incandescent light bulbs are very useful.
They are a high dissipation resistor with a lot of uses.
I have one in series with a bathroom ceiling fan, just kept plugging  
smaller watt values in
until the fan was quiet enough but still fully functional.
I have one in series with a micro drill press, runs with full revs  
but stops when the drill jams.
It will be a pity to see them turn to unobtainium.
cheers,
Neville Michie
