Re: Telephone Message Waiting Indicator Circuit

As far as I know, you don't get any sort of dial tone while the phone is on-hook, so I doubt if this is possible.

Re: PICing it or How I learned to love Microcontrollers

I don't know where this 15 years figure comes from.
I have a 1982 data book from General Instruments which contains PICs. They were originally made by GI before Microchip existed.
Anyway, I make that more like 22 years.
Not that Chris Smith will care one way or the other!

Thankfully I'm grown up now. I still think that it's funny, but I can't b...

Re: Lamp Current vs Voltage

I think I remember reading somewhere, that for 12V halogen lamps, 10% overvoltage reduces lamp life by 50%, and 10% undervoltage reduces light output by 50%.
On the other hand, I could have just dreamt it (not that my having dreamt it would automatically make it false).

Re: A vision

It's not the lemons that provide the energy, it's the dissimilar metal electrodes. The lemon, potato or even saliva just act as the electrolyte.
Sorry, just noticed that this observation has already been made.<p>[ November 01, 2004: Message edited by: John Brown ]</p>
