I'm looking for a device that can, in essesence, make lights brighten
or dim by remote control. Also, the device would be able to shut
electronic objects on and off, all by remote control. The key point
being there would be nothing in the targeted electronic machinery that

Would anyone out there have a data sheet for the NEC D7811HG Please.
Its to help solve some mysteries about a controller board.
Thanks Prolater

I need to try and build a tunable AM receiver for a project I'm doing.
Ideally I want it to span from about 30MHz to 150MHz. I'd also like it
to be digitally tunable. I read some article about how to do it with
an old tuner module from a VCR, but can't seem to find the relevant

They will always shoot me with bolts of electricity and refuse to work
in my designs.Why ?

Doesn't anyone know the approximate power or current requirement for the
non-switchable 12VDC lean on a car radio/cd?  This is the one that maintains
the memory for station settings, the time, etc.
I'm installing a car radio/cd in my house and will supply it with 12VDC from

Someone asked me if I knew of a video time and date stamper.
Basically it is a matchbox (he reckons) that fits in the lead between
a bullet camera and the vcr (digital in this case) and inserts a time
and date stamp on to the picture.  Anyone heard of such a thing?  I've

I could do with the user manual for this camcorder, perhaps in pdf format.
It will stop me from guessing on how to use the many function controls.
I would like to return the favour with other schems I might have.
Thank you

Not sure if you guys can help, but are Toshiba Split System Air Conditioners
any good, or should I steer clear of them ?
Thanks

I'm after a source for low cost 2.8V (2 x D cell) halogen torch globes,
anyone know of any cheap source for these?
The ones I can find (eg, genuine Energizer replacement) are in the
order of $10 a go, and I need quite a few so am looking for a cheaper

I just spent  several hours trying to figure out ORCAD student pspice
circuit simulation ware.  There's no tutorial, there's no "view from 30000
feet" explanation as to how all 8 sub-applications interact with each other,
you can't just create a file representing a circuit, you ...

Hi guys ,

These guys are giving free iPods away for just signing up for some
promotional stuff. (Ever heard of a loss-leader?) I need 5 people to go
to the site using my referrer link and sign up for something. If you do
the same you get a free iPod. It was talked about in Wired magazine

I'm switching over to PICs from Basic Stamps due speed, capacity, and
price reasons.  I've already purchased a semi-universal programmer, and
am looking a couple good PICs to start with.  I was thinking about a
lower end PIC for simple projects, and a mid-range PIC for more

I'm trying to determine if it is possible to import a European
induction cooktop (hob in U.K. terminology) to the U.S. The main
difficulty appears to be the 50Hz/60Hz difference. Not surprisingly,
the manufacturers say it won't work, but I don't know if that is the

Does anyone know where I can source miniature drill bits in the sizes 0.5
mm, 0.6 mm , 0.7 mm for PCB hole drilling?
