After reading about Nikola Tesla, I was wondering if there were any
plans to make your own Wireless Energy Transmitter, such as the one at
the Wardenclyffe Tower. Is this possible? If possible, relatively
inexpensive to do? Thanks.

I've been searching for an RJ10 connector for my PDA charger, rather
unsuccessfully I might add.
Does anyone know where I can get one?  I've found a couple of places on the
net, but they want to charge ~£10 for carriage, for one 10p plug.

I'm building a computer/rc transmitter interface cable which calls for the
2N222 (or better) resistor. I'm assuming the "or better" does not include
the sub I mentioned  but more likely a 2N222A. Having a hard time getting my
hands on true equivelents such as ECG123A  2N2222A ...

Is the better signal to noise ratio the larger or smaller?  For
instance - 80 or 100dB?

Do batteries get heavier as they're charged?

Hello to all nice people;
I appreciate advice on what to do as I am not as clever as some of you out
there. I have a "First Alert" smoke detector installed under the house next
to the heating furnace. I intend detaching the peeper from the detector and

Hey people!!!
About 7 years ago there was a mob somewhere in Australia (melbourne I think)
that sold their own chip burner... It was advertised in Electronics

I am trying to find a mobile phone that can accept 2 x SIM cards that are
both on the network at the same time.  Im guessing this can't be done but
can anyone confirm?  I have seen the dual SIM holders that require the user
to power off/on the phone but this is no good for me.

Does anyone know what is in these devices, what the power source is and
most importantly, how to get into the little suckers. My wife's (Year
2000, 1.6L petrol stationwagon) bleeper died last night, necessitating
a rescue, and without the bleeper, the car is a dead duck.
