Would anyone have a remote to suit a Panasonic NV-SD400 VCR that they would
like to sell.

For the tv that has this feature, ie100Hz etc, a High Definition (HD) tv?
Thanks in advance.

Hey all,
I have been looking everywhere for pink shielded cat 5 cable - either
stranded or solid core, around 25 metres.
All of the computer stores I have tried don't stock it. Middendorp

Should Richard Steve Walz be:
a)  Roaming Newsgroups seeking anyone he may devour (over 20,000 posts since

Cordless phone batteries are way overpriced, over 5 times the individual NiCd
batteries combined! Why is this so?

I blew a transistor in a power supply yesterday and can't find an identical
replacement.  The supply was 25 years old so I figured the transistor is
discontinued.  It is 2N3898 and if someone could point me to an equivalent
I'd really appreciate it.

What is the frequency (range) used in domestic microwave ovens?
Do all ovens use the same frequency?
Is this frequency related with the chemical properties of H2O?

floppy drive at 8mhz for DD mode, 16mhz for HD mode, now I find out theres
10.24mhz for hyper mode, is there anymore speeds I should know about ??

Folks,
  Hope I have the right group here but what does anyone know exactly
what a virtual CPU is?

Looking for a CASIO BATTERY JK-210LT
3.7V 1400 mAh

Can you use a positive plug 4.5v 600mA power adaptor in a device
that calls for a positive plug 4.5v 300mA adaptor without harming the
device? They are both produced by the same company, the only difference
is the mA rating.

I was wondering if anybody could point me in the right direction?  I
am looking for low cost 12V 500mA regulated power supplies, getting
fed up of paying expensive RS and Farnell prices!  They must be
suitable for both US and EU applications, taking in to account

I'm in Automated Home technologies - I need to install a reciever unit (RF -
FCC approved freq.) which will "lay low" and not tax the snot out of
batteries.
For example:  Your RC cars which you purchase from WalMart - use a chip that

Any recommendations for kits, and were to get them for making PC boards
using the resist pen method? I would make 1-3 boards every couple of months
and they would not be all theat complicated.
Thanks!

Could someone recommended a source of info on designing and modifying
class AB Mosfet audio amplifiers? I've got a few that I've half built
with some serious transistor substitutions but they obviously don't work
real well (drawing full current at no load...) and I don't know ...
