Not sure if this is the right part of the forum, but I have just begun (literally today) to do some vector graphics on an Arduino connected to a CRT oscilloscope.
Made some good progress today, 10 rectangles and 10 circles moving about randomly with a good refresh rate of under 10ms.
I'm coding diagonal line drawing routines next.
I'll do a clock first and try a simple game...
Initial test:

Would love to see a YouTube video of this!

Well it's not vectrex related as it's not using any vectrex hardware or software.... I guess this is as good a place as any!
I'm using a very old CRT scope which uses valves! Mainly because it was very cheap and second it looks really cool!
The beam is nowhere near as sharp as a vectrex, but the arduino I'm using has a lot more horsepower than a vectrex. (it actually makes you appreciate what a great bit of design work the vectrex is...)
I pop something on youtube later on today.
I'm still on the lookout for a cheap more modern scope, that's local enough to collect, which will give me a sharper image.

Wow looks like an awesome start.
Is the project specific to the scope or can you just continue where you left off when you get the larger scope you're looking for or run it on any oscilloscope?

Cheers, I got that scope cos it was cheap on ebay and being valve driven its kinda cool, if really heavy and power hungry... I'm on the lookout for a more modern scope, but they are not so cheap. The code will run on any crt scope, but they all tend to be quite small screens. I'm going to try connected the arduino direct to my vectrex (bypassing the stock processor board) and if that works, I'll get a duff vectrex off ebay to use.

Here's my latest video, a 3d cube displayed on a crt oscilloscope.

And here's a classic battlezone tank, drawn in Goggle Sketchup, rendered by an Arduino onto a CRT oscilloscope.

Now you're talkin' (tanking?)

And here it is on the Vectrex....

I saw a much more modern scope in a second hand shop in Perth a while ago. I think they were asking around £80- to £100 for it!
That looks good on the Vectrex screen though. Looks like you could make a pretty fast vector game using the Arduino.
I wonder what you could do with a PI? Couldn't you just convert an old CRT TV to a vector display?

On the same subject, check out this page - www.lofibucket.com/articles/oscilloscope_quake.htmlSome guy figured out how to run Quake on an oscilloscope. Looks very nightmare green. Can you imagine refining this and releasing it in arcades around 1982-83? It would have been the biggest hit in the whole industry. And if it could be done with a color monitor...

I just remembered this thread, and wondered if I could see your Arduino scope code.
I just got an old 1975 Telequipment S61 scope (along with a Philips one, which the screen faded to nothing on and I haven't got it to work since) both for just over a tenner.
But the Telequipment S61 one is fine. So far I've just done some basic tests, and got it to grow mushrooms...
Does the scope have to have an XY scope to work with the Arduino?
