A PI and an old TV set

Thu Oct 04, 2012 8:26 pm

Image Image Image

Here some pictures of my Pi connected to an old colour TV set.

In the 1st photo you couls see the tv displaying a faint LXDE desktop due the flash light, and underside a keyboard, a powered hub, the Raspberry Pi in a cardboard Pummet box and in a tinned steel box a VHF TV modulator, home made.
In the second photo there's a closeup of the Pi and the modulator.

The TV set was the same I was using with my Sinclair QL in 1986. The TV is still used with a satellite receiver, the Sinclair QL unfortunately had a power supply failure and was damaged beyond repair.

The third photo is a photo of the desktop displayed by the TV, showing an image of a test card. Used wide lenses to enhanche the distortion due the cinescope shape.

RF modulator. Goldfish bowl screen. High-tech red channel indicator. Nice.
note: I may or may not know what I'm talking about...

Can't beat early 80's home computer technology.....
Don't judge Linux by the Pi.......
I must not tread on too many sacred cows......

Funny when you think the PI would leave the Sinclair QL in the dust on performance...sometimes it's amazing how far technology has come since then! I started off with a Commodore VIC-20!

It's a kit from Nuova Elettronica. http://www.nuovaelettronica.it/prodotti ... mhz-1-1413



It was a module of a test pattern generator. The interesting thing is that transmits on low VHF band E2-E4 channels instead of the normally used channels 30-39 on UHF.
