anything that gets bounced around.  Any solution for this besides that
cheesily-named d-skin ("duh skin")?
My friend says turn the laser up ( by turning the pot down).

I am looking for a circuit that I can take 2 different 12v inputs as a selector with a single output to an incandecant lamp, one
input would output a reduced voltage to the lamp (say 60%) and the other input when active would cause the lamp to light a
100% of it intensity. A bit ...

While I have only a 40MHz clock connected to a 10 bit ADC, nothing connected
to
the analog input sockets, the chip is Analog AD9218 (ADC chip) EVM board. On
the LA, sampled outputs are 0~16 for one channel, -32~0 for the other

guys i know very little about electronics.but
I have a 6volt toy motor made by solorbots (gm7)
I need a circuit to drive this motor in forwar
for about 2 seconds,the stop(or turn off)for abou

I have a basic 24 volt 40 amp battery charger. It has the basic transformer
and rectifier in it. The input voltage is 240-250 volts 50 cycles AC.
I am trying to control it to charge a set of batteries (4 x 6 Volt T 105)
that in turn run an inverter (24 volt to 240 volts AC; 2.5 Kw) ...

I would like to make a circuit that can switch an appliance on by
calling to a mobile phone.
Does anyone know which pins underneath a nokia mobile phone (6310)
indicate if the phone is ringing.  With the pins I mean the place where

  Im trying to locate a specialist in hard disks, I need some information
on physical disk geometry.
I know that CHS addressing does not directly translate to physical track
location, due to the fact that each track on the disk holds a different

I was hoping somebody here might be able to help me with a question.
First, some background. A couple of months ago I was trying to record
the sounds of the insides of my computer for an experimental sound
project. I first tried it with a cheap, crappy lapel mic that came with

Can anyone tell me and its more just out of interest at the moment.
I asked previously..
Onece a GAL has been programmed can it be duplicated ?
Or is what has been suggested to me about the chip self destructing by tying

Are the standards for HDTV the same worldwide?
I ask because there are Sony 32"  LCD units for sale in England with a
'digital WEGA Engine'.  Is this compatible with the US standard ?
I know the single phase voltage is higher in Europe. 240 I believe, or 220,
