DIY Video Synth On a Budget! How To Circuit The Bend GBS-8100

A massive thanks goes out to all of my Patrons for the support over the last year, I am happy to bring you the first of my tutorials in video format!

In this guide I show you how to circuit bent the GBS-8100 (A VGA to composite converter you can get for £20 on amazon) How to incorporate it into a feedback loop with a composite to VGA converter and provide some really great effects recipes with clear pinouts to take any of the guess work out of this project for you!

Purchase Links:

GBS8100 VGA to CGA RGBS/CVBS/S-Video Converter:

Composite / S-Video to VGA converter:

Enclosure:

Push Buttons:

4mm Banana Jack Sockets & Plugs:

Potentiometers & Knobs:

Toggle Switches:

DC Power Input:

RCA Jacks:

Wire:

A4 Self Adhesive Paper:

Power supply (capable of powering both converters at once)

You will find them much cheaper and of superior quality in general vs sourcing them on Amazon.

Bless your soul, there so few people out there actually teaching and spreading the techniques of this hobby to the no-experience beginner. Certainly none of them have been as helpful as your channel, website, and social medias!

Thanks so much for the video! For anyone wondering, the pots are 1k linear.

this was my first diy electronics project ever, and ur tutorial really was so helpful! with no soldering experience and a cardboard box housing i managed to get it to work first try! plugged it into my gamecube and had a blast messing with Mario Sunshine. thanks again, you’re killing it!

[StephenMcLeod]

Such a cool project. Thank you for sharing! I might have to try my hand at this, though I am sure I will mess up the SMD soldering.

I had no idea you could get this stuff so cheap gawd dayummm, you my sir are a legend, and love all your hardware man it seems class, ive had my eye on the audio reactive one for a while now, will have to pick up sometime soon. Cheers mannnn

oh frick, i know what i am going to make soon!

[theboytheycalljonny]

All-sorts of brilliant! Thanks for sharing.

Very Grateful for this video. this kind of content with everything explained and detailed is still not very common! Quality Stuff. Subbed ;)

[CaziBeats]

I appreciate you so much for the inspiration and tutorial. I built my own GBS video synth after this build. All the bend points work as expected. But I am having difficulties with the output only displaying bends when used with the VGA input on the GBS and the feedback function whenever I switch it on it just gives a video glitch mix of the VGA and RCA input. Do you have any tips to fix this?

This is an amazing resource, thank you for sharing!!

@LofiFuture is there a wiring diagram available for the internals ? for example the buttons ? and the female jack points ? (im guessing the female jack points just go to the pins then that acts as a bridge but where do you wire the buttons in ? :D thanks

Hi ! Thanks for this great DIY, but i have a few questions...

I am on the soldering part, but y have big broblem to correctly solder the wire on the chip. Witch solder station do you use ? And what temperature do you set ?

[maikneufeld]

Thank you so much for this wonderful video!!!! I have a question. Will I get some effects if I put some potentiometers before some of the banana jacks?

[ryanredding]

I'm really interested in building one of these.. I'd really like to see how you hook everything up and record your output

[cooksoni.a]

any tips on soldering to the ram chip? i just destroyed my third board 😭 i tried doing it to the vias too and just cant manage it. maybe i should just give up.

[francescoscarel]

Super nice project! Thanx for sharing

A question: why banana jacks and not 3.5mm minijacks?

[kilypayne]

First off thank you for making this video and sharing your diagrams on this project. I am so close to figuring out this build and I feel like whatever mistake Im making is something basic I've not learned yet since I kinda jumped into this. My video out is giving me colorized static and I'm not sure whats causing it. I dont see any bridged pins on the GBS so I dont think thats it. Trying to get some more info before going back in and de-soldering my work and starting over again!

[qxvqpgg]

could you please explain a bit how the buttons work? :)
can't make sense of how it supposed to connect the circuits.

[jeffreyjbyron]

So you are processing using the AV to VGA converter, circuit bending and using the GBS-8100 AV out? Or VGA out? Sorry I'm new to video synths, but I love this and would like to build one. Don't really want to deal with an AV to VGA converter, but I don't have any VGA video source...except a computer I guess.

I’m having an incredibly hard time with getting the wires onto all those tiny pins, any more advice or tricks to make it a little less painless?
