Neat.
Could one make the 4th "unused" voltage level something out of range of the display, so that the extra lines are not visible?

Our expensive scopes already have time-of-day clocks.

Some guys actually did some similar using a PC soundcard. They made a 'demo' similar to the ones often found for home computers like Commodore 64, Amiga, MSX and so on.

Can't you just tie a long rope on the oscilloscope and make a pendulum out of it?

No need for that, it orbits the sun once a year, all by itself.
Maybe I can get it to sweep exactly once per day.

Good idea. That requires a display module, and a sensor to detect the passage of the scope. You also need some sort of power to overcome the frictional etc. losses in the pendulum. I suspect the PIC coding will be more complex. It will probably also need an accurate oscillator to detect heat, atmospheric etc. influence on the pendulum and to apply corrections.

For you next project, build a device that will accept a string of characters and convert them to a voltage function of time, as in the logo for the Plessey Company:

Here's my company logo, as a vector display and an x-y analog scope:

Hmm, Curious how you got the black out lines around the image? is this a color scope?

Some scopes have a Z-axis intensity/blanking input which could probably be used for that.

Hi, did you do that with photoshop ;-)???? I can do it with gimp LOL. Anyways,I decided to take your challenge, and played this Sunday afternoon:

It is clever, but why not go TV? I could make a movie of my digital clock.....
There is one thing that I didn't understand: are you guys have terribly nothing to do?
If you show a TV picture using an oscilloscope, could it be a way around the TV tax in some countries?

Have you never created designs just for the joy of doing so?
I suspect it is the signal received that is taxed rather than the receiver.

The entire image needs to move slowly around on the screen randomly to prevent screen burn-in.

Can you go the other way and turn a $5 clock into a scope!

Nope; at least, not in the UK. If you receive a TV broadcast (whether by radio, cable, internet[1], etc), you are required to pay the licence fee.
If you have a normal TV set, but only ever use it for watching DVDs (or as a monitor for CCTV or an old home microcomputer), you don't need a licence. OTOH, if you record broadcasts with a VCR, but don't actually have a TV, you still need a licence.
[1] Internet downloads or video-on-demand streams don't require a licence, only broadcasts. The distinction is whether the viewers all watch concurrently, so a a streaming service where each viewer's stream starts when that viewer connects isn't a broadcast.ElectronDepot website is not affiliated with any of the manufacturers or service providers discussed here.
