#20

If you think you deserve this, click here, for etsy or here for ebay.

Here is #20. It basically has three pitch knobs, two of which I added. They all pitch it down, but with pinpoint precision. The effect is quite good. I also added an rca output, but normally I would have added a resistor to fine tune the audio signal, as sometimes it can sound kind of funny. But this time I didn't, to see if folks might prefer it. In the video it is playing through its own speaker, the sound file below it is what I recorded coming from the output.

#19

Number 19 is pretty sweet. It has a pitch knob. Turn it one way, it pitches down, till it starts to glitch out, turn it the other way it pitches it up until it glitches out. If you pitch it too high it can become unstable and die. The best way to get it back, that I have found, is to take a battery out, and reinsert it, or if that fails take a battery out and insert it backwards, then reinsert it correctly. It is real easy to recognize if you have it pitched too high, and very easy to avoid. Along with the pitch knob is an 1/8" output jack I have added. Video:

Here is #18. I had some troubles with it. Apparently what circuit controls the demo, is different from the circuit which generates tones for the keys. I had the thing in demo mode while bending it, then I switched it over to play mode, and none of my bends worked. I figured whomever would rather have bends which affected it while in play mode rather than when in demo, so I rebent the thing, to, in my opinion, much better results. Makes some crazy sounds. It was rather sensitive to touch, so I added body contacts, four to be precise. I also added an 1/8" output so you can sample it, play it through an amp, or possibly stick an 1/8" jack in your mouth and feel the current, though I doubt that would be enjoyable. Video next:

#17, my first guitar

I bought this guitar, and it was non-functional, a rare occurrence with thrift store purchases, so I opened 'er up, and located my problem. Some one had failed to properly secure the lead from a capacitor. I fixed that, and it works awesome now. I wired up a pitch bend, and called it a day.

I guess I'm on #16?

I need to eat, and you need to make noise, so lets work something out. Click here to purchase this machine.

I finished this synth I began a while ago. It is based off of this voice changer that one may purchase at wal-mart for six buckaroos. It is circuit bent of course. Originally it came with a mic and maybe three or four different voice settings, like "alien", "monster", and such like. I took the speaker out, wired that to two fourth inch jacks, took the switch, which changed the voice setting, out and rewired that to a six position rotary switch, and added in two potentiometers, or variable resistors, to change the effects. It produces its own audio signal which can be altered by turning the potentiometers, flipping toggle switches, or by switching which voice setting its on.

had a good day

Man, I found some stuff yesterday at that old thrift store. I had plans to make the rounds of thrift stores in my area, but didn't need to hit all three, cause I found these:

Casiotone MT-210





Casiotone MT-45






Casio SA-35






Talk about luck eh? These go a long with my other thrift store find of the Casio SK-1. Neato. I know that the SA-35, and the MT-45 work, but I haven't gotten round to taking the MT-210 apart, and whatnot. Lokin' forwad to it.

hey

Just sold this and thought I would give an overview of its operation. It is fair to say that there is very little information that I could give which would make a person completely able to play it right off the bat. A good amount of experimentation will be required.

At the right you can see the switch which was previously hidden under a sticker. The switch has three settings which simply change the distortion.





If one wanted, one could use the machine to apply an effect to, say, a guitar or other signal passed through it. To do so you would just flip the top switch, turning on the "modulation" circuit, and plug your external signal source into the input.






If you wanted to hear the sounds the machine can make on it's own flip all the switches, as pictured.

Whoops

Hey yall. Sorry I haven't posted in a long time. As it turns out, a man needs more than amazing talent, and super human will to be a success. This man had to go get a job, which will account for all the missing posts. It's a dang shame, I assure you.

I'm doing something which ain't too far removed from what I did as a vintage electronics salesman, so I'm not in too bad of shape. I probably could come up with some more stuff, and probably will, but it'll take longer.

If it were up to me I would be living in a box right next to the thrift store sticking wires in stuff all day long, but I have familial responsibilities.
