[Swansea Hackspace] Analogue b&w TV,

[David Davies-Day]

Looks like you just covered all the points I was thinking of there Tim.

If there is no scart, I doubt there would be scart on B&W, or no composite yellow and white, there is another way to add an AV input relatively cheaply.

A playstation one Rf cable...

This model is the easiest to use...

Just plug in or solder your AV to the inputs and feed it 5V.
Inside the casing, the wires coming from the PSX multi cable will be left audio, video and 5V,  easy to see two of them going to the external phono sockets, the one that is not is your 5V input for the circuit.

I wouldn't expect a B&W set to show the Rf channel but for reference,  if you wanted to test it on a newer set that receives both analogue and digital,  these units (pretty much all fixed Rf units of that era) will output on CH36.

I've hacked a similar unit to send an AV signal upstairs through the existing coaxial cable.

Dear Alex,

I agree with previous suggestions that you use a Freeview box.

There is of course the issue of connecting the TV to the Freeview
box. If the TV is really ancient then it only has a aerial socket on
the back, so you will have to make sure the Freeview box has a
UHF modulator fitted. The Freeview box then appears as a new
station (the only one in the whole tuning range!) and the channel
change is of course on the Freeview.

If the TV has a SCART connector, then it's easy. You just need to
use a SCART lead to connect to the Freeview box, and again you
select channels using the Freeview.

Some smaller sets had two RCA sockets, one white, one yellow.
If that is the case you need a SCART to RCA lead.

I would not use an up-to-date Freeview box, try and obtain an
old one because the latest boxes may not have SCART or a UHF
modulator!

Next step is to look closely at the front and back of the TV for
connectors. As a minimum there will be a TV coax socket for
the aerial. Hopefully a SCART or some RCA connectors as well.

Good luck!

Timothy Davies
