So check this out... I've got a story for ya....

I've made several tattoo guns in the past and put a few tattoos all over my body with success however I wanted to make a nicer tattoo gun and go over one because my last gun was too fast and caused a bunch of scabs so some bits and pieces of the tat came off while it healed...

anyways I decided that I wanted to make a nice tat gun that has a variable speed and it's rotaty based but is based on an electro magnet...


I went to radioshack and bought an automotive relay to tear appart and take out the electro magnet.... To illustrate how this works, the electro magnet has a plate above it on a spring, so w hen there's no power going to the magnet(or negative power) the spring pulls the plate up but when you give it juice the magnet pulls the plate down...

anyways not to get into the details of the design... this isn't what this topic is about... but in a nutshell the plate is attached to a bar which goes through a shaft and at the end of the shaft is a piercing needle which comes out of a nozzle...

anyways so I was stuck with this delema: how do I make the needle to up a nd down.... I needed something that would work at about 12 volts, would rapidly turn on or off the electro magnet to make the needle move up and down....

I was originally gonna ask my brother to put together a circuit that does this cause he's an electrical engineer.... So I decided to give him a call. I asked him if he could think of an alternative....

he says: "Hey you make music, why not plug the tattoo gun into the power amp and play a sine wave?"

BRILLIANT!!!!

I unplugged my monitors and plugged in the tat gun powered up my emx, turned the volume of my amp up all the way and gave it an overdriven sine wave...

the result: a flawless working tattoo gun with variable speed...


what's really funny is that when you play the synth part keys the tatto gun actually produces different pitches. It's pretty funny.

Thought I'd share with my fellow electribers peace.

... LOL !!

Gotta admit , that made me smile .....

[Argus]

hehehehe!...brilliant ruso!

you can try the WAVEFORM osc with the sine wave and then modify EDIT 1 to get a variable shape and maybe some new tat gun behaviour!!!...or maybe VPM!...

what about starting with a LPFied square and start to rising cutoff to get the change of the needle?...or put modulation on it...

maybe delays...or a chorus...hehehe...


last thing: with a little scale and transmision change you can get the ultrimate porn toy!...just considere it!...by selling this thing you can make a small fortune and retire for life to a house in the mountains with a modular moog and a massive PA system!

oooppss!

pretty hardcore stuff...that combination of surgical tool and somewhat electric stuff just scared me a little!

send the synth through 3 or 4 that way you can play the rest of the parts through speakers

and using the eg int it could help you to fade shading more evenly

[Ruso]

ya except at full volume I would fry all my speakers

guitar cab

[Ruso]

a. I don't play a guitar... and b. why on earth would I plug an electribe into a guitar cab!?!?!?!?

[zalo]

i dont see why you wouldnt want to plug it into a guitar cab

just because its not a flat eq on the speaker doesnt make it bad

character and color is never a negative in my book
