Windows XP on tiny CRT monitor

This is Windows XP being shown on a 1/2" diameter CRT display. The monitor is actually a viewfinder from an old camcorder. I switched two of the deflection yoke wires to fix the reversed display problem.

That was interesting. I recently upgraded from a 20" CRT from 1998 to an LCD monitor (15") from 2005. Yeah I know its 2010 and that that's still obsolete. Any idea on fun you can have with a CRT deflection yoke. And by-the-way, CRT Flyback shock hurts. Its only 15K + volts. What could possibly go wrong?

@Videoman2550 this little 3/4" crt uses much less than 15kv to power it. I've never been bit by high voltage from a flyback, I watched my brother do that when we were teenagers, that was enough for me

That's a nice little demo of what one of these tiny CRTs can do. Have one rattling around in the parts box here somewhere...really should do something with it!

PS: Is that an IBM Model M I hear clattering away there?

Of course it is, best keyboard ever

I did the exact same thing with both a 1/2 inch and a 1-1/2 inch monochrome viewfinder CRTs. I was trying to build a DIY head-up display, using a half-silvered mirror so I could see through the display. Unfortunately, the resolution was very poor on these displays, barely usable at 640x480. Would love to find a 1024x768 LCD the size of a stamp to build a wearable HUD. Guess I will just have to wait until those cell phone displays come with a VGA input.

I"d like to try the myvu crystal, it's 640x480, but they go for $150+ on epay still

64x48 :D

can u do 1080p

Now BSOD this, Microsoft.

what would this crt be used for?

[ultimatebman]

@jforb427 I did that when working on a playstation 2. Its not fun.

time for windows 7 and linux! :P

@fujifilmtest Well as far as over all picture quality and better, more efficient technology. I agree that 20" over 15" is better. But LCDs do have better display quality and are much more energy efficient. That's what I meant by upgrade.

[fujifilmtest]

what resolution is this at? i can only go down to 640x480 on xp. it works, but with an error message.

[fujifilmtest]

@Videoman2550 you mean downgrade. 20" CRT is better than 15" LCD.

[jjovereats]

highest dpi ever!

[Videoman2550]

@jforb427 Ha! You are wise. Thanks for responding. I actually took apart a 5" television from the mid 80s and used the existing CRT FBT circuit to make I think about 1KV power supply. I was going to build a Tesla Coil with it but was content by the 2½ cm arc it produced. How easily entertained I am! LOL
