a dumb question

hi, all

please don’t laugh, i have a rather dumb question:
since i have quite a few obsolete electronic pieces, i’m wondering what
i could build from the components out of them…like a couple old cell
phones, 2 broken stereo systems, a VCR, as well as 56k computer modem

thanks in advance!

Help With a MOV (Varistor?)

Hi all, I know I could buy another power bar, but I’d like to fix up
this one. It had a surge hit it, and of course it took out the MOV,
although the bar’s breaker did not pop. The makings are MDC Z131 09ul. I
believe this to be a 130 volt MOV. It is about 14mm in diameter, with
radial leads (like a ceramic cap).

My question is would the Littlefuse V130LA20A item be a good replacement
for it? It will fit into the power bar no problem.

Thanks,

- Tim –

p.s. here’s the site I’m getting info from;

Colour LCD

Hello

I have bought a LM64C152 colour LCD screen. Is it possible to create more
than 8 different colours on the screen?

There is three different pixel colours Red, Green and Blue but each colour
is on or off because there is only one bit per pixel.

Thanks

WTD: Heathkit binding posts

Hi,

Heath used to use binding posts for many of their products. I am looking
for an exact replacement. According to the manual these are:

75-197 Binding post base red
100-16-18 Binding post cap red

These binding posts are unique in that they do NOT have a circular or "D"
feed through the chassis. They have a scalloped feed through because the
plastic  insulators have 4 posts that align with the chassis.

Anyone know who made these?

Quiet fan for my radio rack

I’m the new proud owner of a R-390A.  (Some will say I’m a fool but
I had to follow my heart!)  It’s rackmount, which is great because
I’ve got rack space.  I want to keep it well fed and ventilated.

At the moment, the rack has a 10" EG&G/Caravel Rotron fan in the top.
It moves a lot of air and generates a fair amount of noise.  Not
bad in a computer room, but I want to hear the radio instead of the
fan.

I anticipate keeping the R-390A on more regularly than my other tube
radios (Heathkits etc.).  Probably several hours a day.

In addition, the radio probably isn’t as thermally stable as it could
be if
I’m sucking lotsa air through it.  Someone might tell me that it’s
bad to use a fan for some other reason.

Which way to go?  Speed control on the fan to slow it down and keep
it quiet?  No fan at all, because the R-390A was designed not to need
it?  Some vastly more quiet and appropriate fan?
