another text

It looks like I am now down to just the lines.
I have been hoping to move on from the look the last few have been taking. This is one step.

Circuit Bent Video - My First Sony

I have been hanging onto this thing for about a year now and finally got around to bending it. It was one of the easier bends I've come across as almost every connection results in a glitch. It merely is a matter of picking which ones you want. I noticed a few trends in the types of glitches connections could create so I'll go through and list them off. While one could likely bend the sound the unit makes, nothing worthwhile happened so it seemed it would be a waste of switches and pots.

No, the drawing tablet is not supposed to be outside the unit. I ended using more switches than I thought I would and did not have room to put the tablet back in the unit. I may just screw it on the outside where it should hold up ok or just build a box for it at some point.

The unit seems to have three basic types of glitches. The first and least drastic is the type which leaves the image somewhat intact. It generally gives a still kaleidoscope effect. The second type is that which fully distorts the image into a movie like effect. Drawing still affects the image it produces. The last kind causes an interference effect that looks like bad tv reception. These are controlled by the potentiometers. I used 2k pots for those but even lower resistance may have been preferable.

The circuit image below lists all of the connections I used. Four are connected through potentiometers. One pot controls two effects via a second switch. Three are independent switches and the last five are daisy chained. The "yellow screen" glitch fades the image into a predominately yellow color. The "gradual distorting" glitch results in the image slowly getting eaten away by distortion for lack of a better way to put it. Coming up with new terminology for hard to describe things can be tiring.

The tablet needs to be removed to realistically be able to work on the circuit. Luckily, it comes off fairly easy. It is considerably easier to get it back on if the board is not screwed down.

In the video below I go through all the effects rather quickly. One could leave it at any point and make more subtle changes as opposed to the more drastic ones which occur here. I initially go through all of the intact glitches before going through the fully distorting ones. At the end are the two interference glitches.

Circuit Bent Speak and Math

I was lucky enough to receive this Speak and Math from a customer at Borders. Somehow we went from me inquiring about a book on Latin he had to talking about circuit bending and him offering me a speak and math in one latte purchasing transaction. I have been working on it between projects and finally called it done this week.

The unit has 5 glitches, 2 loops, a pitch bend, a circuit killer, and one glitch that seems to be self-propelled. It seems to continue to produce randomness indefinitely.

Here is a video of it with some gloved person at the controls. I cut it up to avoid the boredom of watching someone fumbles with switches.

While this site has the bends on the speak and math mapped out somewhat (under schematics/circuitbending), the schematic in mine varied somewhat. Unfortunately, I waited until after I was done soldering everything together to take a picture of the circuit. Nevertheless, one should be able to decipher the connections.

Thanks to Tom the kind customer and professor of philosophy who donated the speak and math.
