I have a few X10 video cameras around my house. A few of them are right on
the edge of the reception range.
Can I make a better antenna for the receiver ? Or  can I buy a better one
somewhere ?

can anyone recommend a company who can do this at a reasonable price,
or advise who NOT to use ?

I know it's an odd request, but I need to replace a worn out metal
mouse pad for my Mouse Systems serial optical mouse, model M411.
Alternatively, does anyone know where I can buy a serial optical
mouse?

Anyone have the schematic for this voltage doubler?

I'm not very understand how does the divide by n counter work?
Thank you

I'm making some LED lights for illumination as part of some costumes,
in fact I have to put these things together tomorrow!
In my prototype I used some ultra-bright reds I had lying around, and
my series resistance calculations were fine.  The device is simply a

can someone enlighten me how I could create a single pulse (12V DC - about
100ms long) from a state change of a 12VDC voltage? In other words, I need
to create a single pulse when the power comes on and also when it goes off
(the hard bit - for me). I guess somehow the pulse could ...

G'day Bastards !
There seems to me such  a long time since we had the opportunity to pray
together.
So on this Sunday morning 24th of October 2004, let's it be an occasion for

This is more of a general question but, is it at all possible to wire,
let's say, an iPod to a series of LEDs that you'd pick up at RadioShack?
Something along the lines of having the LEDs emit in response to the
music, similar to how a stereo's LED indicator  will pulses in ...

Which is the future of television: crt, plasma,
lcd, rear projection, front projection?
I know that the new plasma and LCD screen's aren't exactly built to
last like the old CRT tubes, yet they are way more costly. What do you

Hi to all,
I just got through cleaning a large PCB from a modern 8 valve guitar amp
( Trace Elliot / Gibson ) where the PCB was covered in hard, *white*
coloured spots  -  looked a bit like an infected plant's leaves.  Both sides

I'm working out the best solution for a voltage reference to be used
with an A/D converter in a PIC microcontroller.
I was thinking of using the 5 volt supply for the PIC (from a 7805)
but suspect it will drift over time (eg due to temperature variation)

    A friend wants to display the output of a CCD surveillance camera
on his Toshiba Tecra notebook. Output is standard composite video. Sound
is not important.
I'd appreciate any suggestions on how to do this.

How to adjust the oscillation frequency from the output frequency of 1MHz
crystal oscillator?
Thanks
