Confusing.

Transmission lines are usually at a higher voltage. How did he step it down?
For that matter, how did he connect it to his distribution box?

Yes, there are Fry's in my neighborhood. I will check it out.

Any 2-wire, 80mm, 12VDC, 0.30A (approx) will do. Got a Radio Shack nearby?
http://www.radioshack.com/product/index.jsp?productId=2102826 will do.

Probably cheaper at some place like Frys.

Find another fan that has the same mounting holes (80mm -- note the
*thickness* of the fan, also!) and operates at 12V with <= 0.30A.
Chances are, it's just a generic fan.

If you have access to a lot of surplus fans, look for one
with a ball bearing *and* something that is "quiet" (assuming
noise is an issue).

Sure, if you're to use cable ties and/or duct tape to mount it and assuming
the replacement isn't thicker than the original.

Otherwise, it's good idea to check the thickness and mounting method.

Is that, " £0.50p" some type of currency? (-;

How much is that in US dollars and cents?

If you want long and quiet service, make sure that you get one with roller
bearings, not the cheapo sleeve bearings.

Hi Good Pals,
I'm designing an infrared remote controlled circuit with at least
6 functions. I need ICs that can transmit(thru LED)codes or modulate
signals(from the keypad) and a corresponding ic that will decode or
demodulate the signalsa to activate the loads. A matching circuit for
the IC or circuit of any kind similar to mine will be welcome.
Thanks

Any old IC producing RC5 or whatever code will do at your sending end. I
would think that the easiest thing to do would be to break down an old
remote control handset, and cull all the necessary parts to make your custom
sender. I'm not sure if there are any dedicated decoder ICs still available
these days though. As far as I know, just about every piece of equipment
that uses remote control, carries out the decoding as a background task of
the system control processor. It would, however, be a trivial job to program
a PIC to do the job, and I am sure that ready written code modules for just
about any commonly used data format, would be readily available for free
download on the 'net.

Please can anyone show me an easy- to- use PCB software that can
automaticaly prepare a circuit board after drawing the schematic
diagram? Or one that you just mount the components to get PCB.

Hi, I recently used the services of http://www.expresspcb.com/ the
service was excellent, probably not as sophisticated as some but the
miniPCB deal (Three 2.5"x3.8" boards for $50) is excellent, quality was
good, fast shipping with DC etc.

You should be able to find the shareware versions of IVEX Windraft
and WinBoard on the web for download. The product is no longer
supported, and has a bit of a learning curve. I think the free version
has a 100 pin limit. Product had a few bugs and went through several
revisions, but it should do what you want.

There probably is nothing that can do a reasonable job of
"automatically" creating a board layout, given just the schematic (but I
could be wrong). However, there are packages that have schematic capture
and board layout components that work together to assist *you* to create
the layout.

KiCad http://kicad.sourceforge.net/wiki/index.php/Main_Page and gEDA
http://www.gpleda.org/ are each free, open source suites with schematic
capture and board layout.

KiCad has a reasonably active and supportive user community and is
available in versions for both Linux and MS Windows. The principal
author's homepage is over at http://iut-tice.ujf-grenoble.fr/kicad/

I'm less familiar with gEDA. As far as I know, there is not an official
MS Windows distribution available. DJ Delorie may drop by with more
info, though...

You can Change the crystal. Is the crystal the metal can type? If yes
replace it with a 27 MHZ type. These are normally found in Toy cars

Thx for the replies..

I pulled the chassis to bring it home - the set is at my other house
and I did not have any tools there.

Therefore I have not replaced the fuse yet as I have nothing to
connect it to.

I was thingking about a low voltage issue because of the remote not
working, I just don't know where that fuse is in the ckt and something
is getting volts as it tries to start. Since it was near the horiz
section I made an assumption. could be wrong.
Don't know if the whistle I hear is the horiz freq or the switching
supply.

I was thinking that is was the AC line fuse that was blackened.
however from what you said it doesn't sound like it. I don't know what
other fuse you could be referring to other than a small chemical fuse
on a 27 inch set though. Lenny.

This set tries to start four times. HV spikes to 20KV each time and
then decays to zero. I've seen where "three strikes" on some of the
RCA's and the Proscan' s pointed to flyback but I'm not sure I've seen
four. Does anyone have any notes on this one?: Thanks, Lenny

If you suspect the flyback, look at the collector pulse with your scope.
