Yamaha Synth Cross Bent With a 486 computer motherboard

(WARNING): This video too is not for mainstream consumption, actually, this video has lots of..ummm...interesting sounds, a few volume tweaks, and general mayhem. So if you are looking for a good song to dance to, this ain't it.

Now, I circuit bent my Yamaha PSS-80 with 3 wires attached to some blue thing on the circut board, and to the ground. In this one, I'm shorting the wires out against parts of an IBM 486 SLC motherboard that's pretty much long gone as working goes. It's kind of odd that it makes THAT much of a difference between just doing hte usual bends, and shorting out through a motherboard chipset, and even the 486 SLC Processor itself.

oh so there is two clock things and you can switch thought the clocks

[creepingnet]

I think that's what was happening between the System clock on the motherboard, and whatever wires I touched to it. I was running the keyboard through everything, including the 486 SLC CPU itself, the chipset, memory sockets, and expansion slots.

nice did you remove the clock oscolater thing or add wires to it

[creepingnet]

I added wires to the ground, clock/ocillator, and 2 points on the chip I think, the one I use the most is the ocillator and ground wires.

Low and behold a few days later i'm walking past a skip, and there's an old knackered out P3 motherboard. So back to the cave i went,filled with glee at the perversion i was set to engage in... CAUTION: for unknown reasons extreme surges in volume can occur,i stupidly ran this thru my studio monitors, but it was unlike the common bending surges, way more violent and 'watted' up to fuck. did you find this at all?

[creepingnet]

Yeah, that's when you start running into the digital volume control circuit on the board that it surges. Before the video, I ran the wires out of a notch I made in the side of the case, so I could run the keyboard with the case closed.

I remember when I had an old 386 dos pc lmao. the tower was massive.

BLOWING ME MIND

at 3:46 i can hear baby smt tantal capacitor crying about resistance of near by processor socket.

sweet

aaaaaaaaaaaaaaaaaaaaaaaaaaaaaa­aahahahaha

[GOREG4SM]

nice work

i could probably dance to this song

[grooveclubhouse]

great idea! I have an old 486 sitting around. now to think of what to bend it to....

[cotton509]

ok i added to mucht power to a burner circit piece and it exploded in my face ok i am fine thought it was scary
