One major reason the luminance signals of television are broadcasted on
an AM-carrier instead of FM is because FM requires large amounts of
bandwidth. Is there a way to use FM video without hogging so much bandwidth?

Im looking for a position sensing potentiometer that has a hole in it
where the shaft would be. It is an ordinary potentiometer but does not
have a shaft - it gets slipped onto a shaft.  If any one could help me
locate such a thing I would be grateful.

What is the full name (or website) of the company referred to in
designations like 2N3055S/DSI, BD246A/DSI, IRF140/DSI, etc. used by
component vendors?
I believe their logo too is just "dsi" in somewhat stilized, small

There is a new family of PICAXE microprocessors. These can be
prgrammed in cicuit with merely  a serial cable. They will rum to
20MhZ and are th best thing that has happened in the world of
microprocessors. They use Ameican technology but are British built

I'm looking for a data level translator chip to connect a 5V mcu to a
3.3V radio modem. The ideal chip should provide full 4 way level
translation for rxd,txd,rts and cts signals with no external parts (sort
of a 4x MAX3370). A double 2 way arrangement using two chips would be

I have a fairly odd need here.
Basically, I would like to extend the RAM of a PIC18F from 4KB to around
20KB so that I can create some sortof framebuffer for a 130x130 lcd
screen. Being simple chips, PICs can't address external RAM like, say,

I want to plot an impulse: So, how do I measure a force up to 500N with
a precision of 0.1N and high time resolution?
In the same time, I want to plot the way of another component, so
exactly as above I need a sonsor with high time resolution and a way up

i need to replace a  SN755518N VFD driver but none of the usuall sources
have it
mouser/arrow/avnet etc...
how do i find a compatible replacement ? or is there an old stock source

i have a 40 pin VFD driver chip SN755518N that three of the pins Q20 Q21
appeared to have gone quiet/died . Q24 seems to have its expected output
mangled.
I am trying to figure out wether i need to check out those lines (how and
