Don’t trouble yourself with a schematic if you dont want to, but it would be really nice to see what kind of stuff you are doing. And my email is one1two2three3four@gmail.com :-p

I’m pretty much stuck making some lines go up and down :-D

sounds great!

Also, any special trick to getting the “mouth” red and blue lines to move up and down ?

well… the top line was just the inverted signal of the bottom line… the movement came from an envelope follower which does half wave rectification of audio signals. i could just email(1234?) you a schematic if you like and you could just adapt it or bits of it to what you’re doing. s’really simple.

i have been working on something new yes… i think the results are some crazy so far..! am hoping to start documenting it by friday or so.

It’s funny you mention frying chips, the AND gate says it likes up to 5.5V supply, and will handle maximum 7, but I’m feeding it a bit more than 7 and it’s doing great (outputs are very hot (electrically, not physically)).

That’s weird, it’s a tad bit warm but nothing serious. We’re good for speed, and as for any interesting results? Not really… until I get more digital chips (shift registers, maybe an ADC), I’m pretty much stuck making some lines go up and down :-D

Everything works and that’s all that matters! (these chips are going beyond max specs in the datasheets I think)

Have you found anything new? Also, any special trick to getting the “mouth” red and blue lines to move up and down?

the 40106…the schmitt-trigger… you know i seem to recall that i was having better luck with the ttl 7400 versions…
i thought i read somewhere that 5ns was an upper limit for cmos and i think you’d need more headroom in terms of speed… do you have the highspeed cmos? (HTC version or something?)

and for some reason i think you have to run the hsynch through an and (or xor? or nand?) gate with the vsynch before the schmitt-trigger if you actually want to see anything on the screen… not sure why but i could only get a line at the edge of the screen without doing that…

so yeah. maybe try TTL (but don’t fry them chips with the voltage; ) or try some kind of highspeed CMOS if you haven’t already…

i’m curious as to the results you’ve had so far though…

.......

the laser stuff… well that particular installation was a collaboration with robyn moody and he’s most certainly the brains of all the electronics and lasers and stuff there… he also made some kind of giant spaceship / life-support system for goldfish once.

CD40106 is inverting, but it doesn’t seem to like this signal. It is probably because (these are CMOS logic) I am running off of about 7 volts, and that changes the trigger threshold.

I saw your other projects like the laser briefcase, crazy! :-p

what’s a “Halp” though?

does a 40106 have an inverted input? or you can just use something else to invert.
60Hz for an H-sync seems like a weird number to me for some reason at the moment…

but i just got back into town

Was that a problem for you?

So far, I destroyed my old monitor’s cable (mistake, but I didn’t want to go out buying sockets and blah), found the v and h sync, pulled out my video card’s second output, and put the v and h sync onto a breadboard, feeding them into the second monitor.

Then, I put the vsync into a binary counter, and that divided pulses, then took some of those outputs into a AND gate, then fed that into the green and blue channels, I just have to get something to convert incomming audio into some sort of control voltage… Halp? vactrol?
