Some of you may have seen this:
http://www.thinkgeek.com/electronics/musical-instruments/c4e1/

A $49 handheld pattern based sequencer. Circuit bending circles have been waiting for it's release to see if it could be used for parts, bent, etc.

I got mine today and thought I'd share a few pics of the inside.

Unfortunately the actual guts are of the "black blob" variety and Surface mount stuff which doesn't lend itself to hacking but I did manage to burn out the internal speaker in less than a minute so that's something smile

The main "brain":


The matrix:


I have discovered the only two easily bendable components are the most fragile. These are two resistors attached to the internal speak/headphone jack. I *think* they are about 8-10 ohm and have miraculously burned one of them out twice by plugging in the headphone jack. Will be tracking that down later but here's a pic of the area:


Anyone else take a look at this creature yet? The main chip is labeled so I'm wondering if there is some master plan which can modify it? The sounds are all digital playback cheap casio type things but the interface is cool as hell and they can be linked together as well.

ive been watching the hype on these things and the usability of it's guts. i almost bought 2 the other day. keen to see what fun things can be done with the pads

Blobs can be bent..........no problem.

But I guess with fm sounds, no real nice happy accidents will occur.

the hackosphere is interested in this because it's a relatively cheap, readymade scanning button matrix with LEDs in a spacious case. From the looks of it it's really simple, diodes in the right places, everything brought down to a DIL header. You can fit an arduino in there easy, then it's just a matter of fitting a USB connector and you're off - 80 dollar hackable controller.

something needs to be done. the demos sounds horrible. i like the idea of adding in the arduino maybe get something going on controlling sound and video. cant wait to see what comes of it. i would give it a shot but for $80 i cant experiment. if it broke i would cry and you guys would never hear the end of it.

Hey Guys;...
Does anybody has a clue where the clock crystal is on this thing?
I saw this silver long cilinder thingy next to where all the caps are ....but I'm not sure hmmm..... ..... it's marked X1 on the board...
If i find the crystal I'll replace it by a precision oscillator so the thing can be tuned very low and high....
Thanx

"X" is a typical designator for a crystal, so "X1" is probably a crystal.

Once someone figures out how to pop an arduino into this. Bye-bye Monome 40h

Hello!
Im from sweden and i hope that you are tolerant with my spelling.

This is my first post here, and i found this thread after searching the net for possibilities to do something really funny with my Blip.
My first thought was to use it as is, with effects in my daw.
But then i noticed the Gakken sx-150 and i started to have trouble sleeping at night.
A Gakken and a Bliptronic in the same box.
"The TB303 of 2009"
When i close my eyes i see the sync jacks as CV jacks.

Could this be possible somehow?

My hope is as usual, that someone more intelligent than me, could find a way to make this happen.

Ok I pulled it out and wired it with getlofi's LTC presicion oscillator...No pitch control very frustrating just delayed leds and no sound...I've Put it back in
Seems to me the bliptronic Is'nt a hacker's delight at all...
I don't wanna use it as a controller or whatever I want it to make cool sounds in a sequenced way....Too bad that's not gonna happen

You would need to use an oscillator with a similar frequency to the crystal. If it's a crystal up in the megahertz, then that's what you'd need.

hey jazz.com,

i have a gakken with cv / gate input mode, and actually a bleep tronic - i can give a go tomorrow - in fairness i'm not sure is the sync output on the bleep is a cv in kind of thing ...

I haven't been having much luck finding a bend in this sucker either. I did notice that the white keyboard is glow-in-the-dark however smile

I used the getlofi LTC
This oscillator had got a pretty broad range

I think it just doesn't work with everything....

I wonder if the voice switch can be shorted to get two (or more) voices at a time?

If indeed it is FM I don't think changing the clock would do much to the actual sound? Likely it would just slow down the cpu, if the FM chip and cpu are separate, could be wrong though.

The small board with the blob has labels for the pins, and seems to have a part number on it, has anyone googled for a datatsheet? I don't have one and can't quite make out the part number on the picture, but that would be a good place to start.

That goes to 30KHz. I don't know what the Bliptronic uses, but if it's a microprocessor crystal of say 8Mhz, then you're running several hundred times too slow for it to sound normal.

Any luck bending yet?
The soundchip seems not really flexible....

Look again it goes to 33 Mhz....


Anyway I guess it's not working with the bliptronic soundchip...
