Do not try and bend the circuit, that's impossible. Instead only try to realize the truth. There is no circuit. then you will see it is not the circuit that bends, it is only yourself.
I just learned the term "circuit bending" last night, in the middle of the night when I was half asleep. This video is brilliant! I absolutely love how and well-thought-out this video was, and how systematically it teaches how to wreak chaos. Thank you so much for putting this together and sharing your extensive knowledge. This is how mankind has risen to our current lofty heights; standing on the shoulders of giants.
I'm here after watching the circuit bent bible video. thanks for teaching me what circuit bending is AND how to do it. One Question though; What would you say your accent is from?? I keep hearing a lot of people on youtube with it but I've never met anyone with it or heard it in movies.
Andrew Miller Ha, me too. I was all, "wtf is circuit bending? It looks awesome." This video answered my questions quite well and in an enjoyable fashion.
No idea. I'm Swedish but I don't have a typical Swedish accent. I've lived in the states and Britain, I've studied for many years at an English speaking university with plenty of accents around, I've consumed so much English speaking culture from all over, and that all somewhat made it into the way I speak. So the long and short of it, I don't know.
Have you not heard the Muppet Swedish Chef? Actually he doesn't sound too similar, but he is basically doing with electronics what the Swedish Chef did with food items. lol. Bork! Bork! Bork!
I compulsively organize my components, that doesn’t not make me a hoarder. I have a lot of new components and I have a lot of salvaged and desoldered ones as well.
How hard & expensive would it be to add a variable speed oscillating circuit to the pitch resistors, so it’d behave like a tremolo - (like an LFO that can be toggled on/off and even go into audio-rate range, maybe even with a depth and speed knob) This video is my first foray into this world of circuit bending so I’m a complete noob.
man i had a danolectro chorus pedal that made crazy pitch bending squeals when it was almost out of power, for about 2-3 minutes. I wish i would have kept it to learn how to make it do that all the time
Hey there I'm trying to figure out how to wire the switched audio jack or which kind to even use. Any tips on which jack you used and/or how to wire it properly?
Well generally they don’t run on mains power directly, it’s transformed down to a lower DC voltage within the device. I never said that you shouldn’t do it, but you should know what you’re doing before you start as it could kill you if you screw up.
It’s just one speaker, so it’s just a mono source. Mono converted to stereo will still just be mono from multiple speakers. So no, unless the source is stereo you cannot make it stereo.
the older the toy , the better the chance for more bend points . newer toys use black blob single chip - not may points to experiment with . older toys may offer many more individual ic chips , which in turn offers many more points at which to test for bends .
Aaaagggh! You should’ve put the potentiometer in reverse so dialling up would increase pitch. Makes me sad this isn’t the case. Brilliant video though! Very interesting.
@@hassroek a few comments below this he explains that he's Swedish, but that his accent when he's speaking English is a portmanteau of the accents of the various English-speaking places he's lived (also his accent still seems to retain the sing-song-ness of Swedish; spoken Norwegian has similar qualities, but is more nasal and Germanic sounding imo)
I did this with a Casio keyboard about 30-35 years ago. I found a couple of spots that gave me a very musical vibrato and tremolo, and also a few spots that kicked in squawks and squeals and even a frequency divider.
One suggestion, since a POT is basically a short when it''s at its lowest setting, it's always a good idea to have a low value resistor in series with any POTs you put in a circuit to avoid overcurrent. Also 555s, VCOs and PLLs make for some easy ways to add/alter sounds on a keyboard like this. Cheers.
I'm sad that I can't do something like that. And I wonder, it's probably possible to achieve "kid's toy with a low battery" sound, bc it's the most glitchy thing and I love it
That's a popular circuit bending technique! In fact, undervolt and overvolt are features of the SID Station, which is used in a lot of today's pop music.
Yep, just cut the cable to the battery and solder a variable resistor (potentiometer with the middle lug connected to either of the outer two) in between Please take out the batteries first ;)
lol. i've got exactly the same "keyboard". i added a jack socket, so i could send it to my guitar fx pedal. after that, the built in speaker worked as a microphone, so i installed a switch, to switch the microphone/spekaer on and off. when the speaker is turned on, and the "keyboard" is connected to an old distorting guitar amp, you can play the thing with some pretty nice/harsh feedback. perfect for electropunkish/industrial thingies. ah yeah, and i soldered in a 10 M Ohm poti for the pitch. at the lowest pitch, the "keyboard" crashes :D
Reality rupture you would attach one leg of the low value resistior to one side of the alligator clips to limit the current. Then you can use the other leg of the resistior to test connections
Reality rupture what i mean by avoid frying it i mean if you accidently connected the terminal that is used for the battery to a connection that is sensetive to the microcontroller or to that amplifier used for the speaker (the thing with several resistiors, caps and transistors) it will just release all its energy into the part (dump a lot of its amperage). What can happen if you do this is that you burn the components or microcontroller's inside (the ladder not being that common) because you added too much energy to the wrong place. The reason its called 'frying' is that if you poke the wrong terminal of the microcontroller or speaker amplifier then it could cause the thing to get really hot (or sometimes catch fire) to the point it could be able to fry some food on it.
ahh I`ve been thinking about giving circuit bending a try for about maybeee....10 years and it seems I`ll finally get on with doing exactly that. Thanks a lot for the video it was more than helpful. When I initially discovered the soothing (and I say it unironically) sounds of those bent circuits I instantly got hooked but back than (around 2008/9) there wasn`t exactly a wide selection of videos on how to do it, in fact there were none whatsoever the best thing I was able to find at the time was some proper engineering schematics which ofc were absolutely incomprehensible for me and it all seemed waaaaay too complicated for me. Many, many thanks to you sir.
Nothing thats the risk you can crash the software on the die or you can kill the mcu die by frying its internal mos transistors so dont connect them directly to the battery you cant fix a fried mcu die
About to start my first bend on a Yamaha PSS 130. I'm going to be self-taught learning from RU-vid videos and I'll definitely not plug it in. I got some batteries for it.. I'm looking forward to this. Something that's new to me.
LOVE IT!!! The animal sounds pitch bending was awesome.... I so want to give this a go, but I don't think I'll be breaking into my Access Virus C any time soon!
Hey, i know you prolly aint gonna answer since its an old video but if i have a keyboard that runs on battery and mains, can i use it or is it dangerous
Hi! I could really use some help with pointing me in the right direction. I have a toy that I wanna tweak, but not circut bend. I wanna change the sound designated to the buttons to a custom sound. Is it possible to change out the sounds in the hardware?
A custom sound? Yeah, you’re going to need to completely rewire that whole thing, hook up a separate device that can play back the sound from memory (unless you want to generate the sound through circuitry), and then you’d need to rewire the buttons to trigger that device instead of the toy’s internal circuitry. If you’re lucky you may be able to tap into the internal amplifier for the speaker, and use the internal batteries, but it’s going to be one heck of a hack. If you don’t know where to start you have a pretty steep uphill climb ahead of you.
Subb Par Productions you can make one by buying a rotary switch or whatever switch you have, and also buy 2 headphone jacks. connect the ground to the switch from the circuit board, and then connect one of the switchs out put to the headphone jack1, and the plug the other switches output to headphone jack2. Now the switch will choose which headphone jack will complete the circuit
Thank you for the prompt response but I still would like to be able to buy one that automatically switches when something is put into the Jack, do you know of anywhere that is selling these currently?
I am 15, Swedish, I've had it since I was 3 years to about 5. I have given it to my little brother, he still has it. I could if it has a "Made in ..." inprint on it.
Hej! Jo, den har "made in", men som 99% av dylika saker är den gjord i Kina. Verkar vara en Keyboard som tillvekats i stort antal för all olika butiker ska kunna sälja under sitt eget namn.
Sometimes you just need a project like this to make your day. No real use but it does get one motivated. I tend to strip thinks and record or do something really simple when I get that itch but don't want to commit to a long build.
Sorry guys but I would have to disagree... No real use??? This is our future happening before ur eyes... I can see all kinds of musicians and artists using these skills and have IRL Y0!!!
