How to circuit bend video devices FROM SCRATCH || Sansui VX-99 video bending Tutorial || Glitch

Crappy audio and video quality, but it should do the job. I hope it will be useful. Have fun and be afraid of electricity ;)

Amazing results! Really inspiring video you made there!

I am not knocking your approach, Maestro.

Your method is how I have interacted with this test universe's 'reality index machine' to great success. ;-)

[jaroslavmaler]

Thank you so much! With your tutorial I managed to successfully bend my own Carena MVP-4000 and works like a charm!

[EvanKakouris]

Insanely helpful video! Love your work and thank you for this gem! I just got a videotech vec1070 and was overwhelmed with it, first time circuit bending video devices. thanks again!

If you want to avoid the plus and minus legs to not touch I'd recommend using individual small shrink bands around both.

[robinsutcliffe_video_art]

Thanks for the video, it's nice to see your process. I would recommend placing a medium thickness clear plastic sheet over the PSU when the case is open. Especially when reaching for the components above it, it's so easy to drop something and then automatically grab for it. Or the metal legs short something powerful.

I also love using multimeter test cables that i cut and soldered to aligator clips, really helps my poking process

Thank you for this video its so helpful!

[robertcrystals]

I like that the machine still looks usable as it's stock intention too. I've got the same machine that wont power up that i want to do something with.

Ciao! Lavoro supermagnifico! Complimenti!

Domanda: che tipo di LED e fotoresistenza hai usato per il vactol?

[ReverenddMEOW]

I need to find some "Speak & Spell" units, which have the same Speech Synthesis LPC chip as my TI 99/4A's free speech synthesizer cartridge. I only got as far as some Basic loops feeding it random Phonemes in random-length sentences.

Now, with greater education in this arena, adding some random Boolean Logic equations set in base-level 74HCxxx logic ICs and Analog/Digital multiplexers to 'automate' its actions is more educational, maybe?

Oddly enough, the local power company's autocall bill collector's voice changed from a Scaninavian-tinged English, but after a minute, it freaked-out and began spitting-out random Norwegian phonemes in random length sentences, just like the experiments with the Speak & Spell Texas Instrument Speech Synthesizer IC that same week.

Thank You for this instructional video, Maestro.

Databooks are our friend.

I simply cannot believe how many of these all-too-common "RAM OverClocking Tips" from pretenders do not reference RAM Databooks, wasting mine and million others timme to no end.

Thank you for this video! Amazing work and very inspiring. I'm working on bending a small device now and I was curious about how you start with the video input pin - I assume you're routing this signal to each of the potentiometers, then routing separating ICs to each pot for different effects? If that's the case, how is the video signal chained in between pots? If thats not the case, can you offer some tips on how you've wired the pots to interact with the video signal?

[dingbatfpv]

Great video, it's nice to see the process

[padenmrl]

super helpful video! I'm just getting into circuit bending/electronics in general and was wondering why you are using capacitors instead of resistors?

[nightmaresands]

Would be possible to modify audio channels or circuits on this? For example you would connect external audio and the knobs would tweak or bend sound to distort a song which then goes to an external source such as speakers? Also could this unit create audio reactive glitch fx since it has audio in?

[fotoniknoise]

Wow, great stuff! I have three questions if I may:
- did you circuit bend while using the wall adapter?
- if not, how did you manage to see the effects while experimenting with connections? Would a 12v battery be safe in that case?
- is this Bremen in the video?
Keep it up man, you did a great job

[janhundling]

Awesome video thanks so much! A few questions:

- Do you always use a resistance/pot in between the points when looking for new connections? If so, what value of resistance?
- Can you also connect safe (no GND or voltage) IC pins with other IC pins? In the end sheet you only connected ICs to their own points or to the video input.
- How do you select capacitor values? You seem to just go by trial and error, but what do high/low values do to the signal generally?
- Does the order of cap -> pot / pot -> cap matter?
- Regarding the CV input; Does the photoresistor add resistance to potmeter in the connection?
- Regarding the CV input(2); Why dont you connect the photoresistor in serial to the bend point?

Thx!

[boredview]

Amazing in depht video thank you so much!

[caesarblanko]

we have the same trinitron wega :) there must be a way in the service menu to get rid of the av4 / program references!

[mattflashman]

amazing video! what's your thoughts on using a continuity tester to check the chip voltages rather than looking up the data sheets?

[antblanc]

Awesome and very inspiring video, thanks! Just got a question. What if you send a negative voltage to your CV input using the vactrol? That will work or simply will ignore the negative side? Thanks again for sharing it!
