Yes. I thought it was kinda of obscure so I'm surprised that someone recognized it

And the third image looks like Jean-Luc Picard of Star Trek TNG. I don't recognise the middle one though.

Right you are. And that's just a static picture, not from a show so that's not surprising.

Great work !i think you are using Gary's ghgm2c 2 colour left right channel 2 colour ...BTW there's also a 120 line 2 colour version
He also has this 3 colour Baird system this would be one channel .least i think it is i have not played with colour much ..

I've actually been using my own software for all the tests. I prefer to run it at a higher framerate (15-16 FPS usually) to help tame the flicker.
I'm looking for software that will let me play four track audio or two audio files synchronized on two different devices (since the sound chip can treat the front and back ports as separate devices) but so far I've had no luck. I might have to roll my own :/

To be fair, it is waaay before my time.

Yes, and on the second picture Picard and Riker. Good quality. A better Nipkow-disk would also improve the picture a lot.

Success! I have sound and color working.

I had to set my audio control panel up for "quadraphonic" speakers. I tried it before but it turns out I was using the wrong jacks.

Also, it is quite hard to find a media player that will play 4 channel WAV files. Foobar 2000 does it

I am very impressed with your work! Cool that you were so young when you originally created it. Interesting that you were using a Brushless Motor. I didn't go that route even though I have a lot of them around. Are you able to maintain a good stable rpm with it or do you have it constantly being adjusted?

In case I missed it, do you have links to your TV on youtube? Would love to see it.

I'm actually not using a brushless motor but I understand where the confusion comes from. The video head is just used for its bearing. I actually have a 6V brushed DC motor which spins the disk through a belt and pulley system (approx. 5:1 ratio). I do get quite a stable picture though.

There are a few video links earlier in this thread. The ones I have on youtube are before I added color to the LED matrix but here is one: https://www.youtube.com/watch?v=N9y5gnXwvoc

I have watched all of your videos over the last week thanks. I am so very impressed by you and so many of the people on this forum's work.

I believe I saw some Acronym of a motor that made me think it stood for brushless. No matter.

Would be fun to watch "The Twilight Zone" shows on a TV such as yours.

Impressed as your's is a do it your self every thing...good work indeed.
Should look into a 2 drum or disk system and get some nice size to your screen...its a little more to it than a Nipkow but crt screen size is worth it !

Thank you. I was mulling over 3d printing a mirror drum system. But I don't know if my 3d printer is precise enough.
Also, I find scophony systems are very interesting. But probably quite hard to build. Especially without using a laser.

Wow that is great Smeeze!!!!


Thanks!
It looks better in real life. The black bars is a well known issue when trying to record mechanical displays
