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!
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!
So this would be okay for a beginner? I took an electronics course ten years ago. Haven't soldered in ages but this project looks like a lot of fun. Thank you LoFiFuture! I love your filters, very psychedelic!
@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
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
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 ?
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.
@@finonomastropiero4261 i did too, i ended up skipping some of the pins so i had more space to solder the wires. Ended up doing 12 pins, some of them came undone but i cant be bothered to retry it, at least right now lol. I can still get plenty of great textures with the ones that did work tho Also getting a better soldering iron was life changing lol
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?
No problem! Its been a goal of mine to start making video tutorials for years now. I have made a few PDF guides over the past year but I feel I can convey so much more information in a video!
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?
Thank you and no problem! This is a really good question and im glad you asked it, should have explained in the video. First reason is if buying cheep then cheep 3.5mm jacks are pretty annoying to use + grab onto jacks too hard for quick patching. These cheep 4mm banana jacks however are super smooth and easy to patch. Second reason is kind of a safety feature, with 3.5 mm jacks one may be tempted to plug in external signals. Since the patch points are not buffered (and it would be much more effort to do so) you could easily kill the chip if you fed it an audio signal that exceeds 3.3V (4.6V absolute maximum according to the datasheet) The data sheet also mentions exposure to voltages above 3.3v for prolonged time may effects device reliability so this prevents any mishaps that may occur from haphazardly sending the chip loud VCO signals. Obviously if you have banana jack modular hanging around it would be a risk, All that being said sending the chip all sorts of signals is super fun, but i will be covering how to send the chip external signals safely sometime soon
@@LoFiFuture I see! I was indeed tempted to patch the chip with external signals :) but maybe would be nice to try some lxz stuff such as the lfo, they use 0to1 V so they should be safe!
@@LoFiFuture oh ok. This answers my question. I wondered if you could send trigger gates into the unit .. but that might be a mistake. Thanks for the extra info
@@LoFiFuture incredible. thank you! will this impact the build? i just bought everything and was going to start today! PS how long do you recommend the 28 awg cable to be? looks like you did abt 6-8 inches?
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.
one thing I would try is using a flux pen during soldering especially if it seems like the solder just wont flow. I have found a set of Vias on the other side of the GBS-8100 PCB that are way easier to solder too. I'll make sure to document this and add it to the project page when i get a chance!
@@LoFiFuture just subbed to ur patreon! and anticipating the alternate method while i attempt at doing the original feedback loop generator in the meantime :)
Really cool. I would love to build this for my band. I'm not a video guy, so sorry if this is a noobie question, but is it possible to connect a video camera to an input on this?
I see you use 30 AWG wire... I've seen elsewhere that 18-26 can be more suitable. Will 30AWG be okay for dirty video mixers too? I have loads of and would save me buying different gauge
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!
This happened to me too and after using a multimeter to check continuity I realized I did indeed have bridged connections :/ Unfortunately the pins are so small that both a solder pump and desolder wic has not work to unbridge the connections. Back to square one…
@@YapScience @Sam Bianculli those pins can be very frustrating to solder for sure! I ruined a few gbs's before getting it right! One thing I realized is if i am using the feedback mode I have to unplug the video input first or else it will cause the video signal to drop 🤦
Is there a difference between the grey and the black vga- to composite converters? Do i need the two to use them in pair as a feedback loop? I cant just buy two blacks or two greys? My question is if they transport the signal just one way or if they go both ways. Ebay descriptions give me nothing… Heh.. Thanks!
hi, is it possible to exchange banana jack againt jack 3.5?? and do you now what's value of voltage we can inject in the chipset?? thanks for you share
Great video, thank you! Can you please point me to the labels? I can't seem to find the link. Also, can you confirm it's only necessary to use the pins you labeled as "safe to short"? Or are all 50 pins needed? Keep up the great work!
Thank you! You can find them on my website under the GBS8100 Video Synth Tab. You can basically take any selection of the "safe to short" pins you want to create your device. It isn't necessary to use them all and the pinouts provided on my website include some narrowed down pin selections for certain effects.
Thanks so much for this video, I'm going to be working in making something like this very soon! Quick question: exactly what kind of capacitor did you use to convert s-video to composite out, 1k volts?
Thank you so much for this content! On the contrary, which one do you recommend if I prefer to buy a ready-to-use gear to create exactly the same glitches like this?
Your very welcome! If you look at my last upload before this a demo of what I am calling the Glitchscaper that features all the stuff this project can do with 2x internal LFOs and a buffered audio to glitch circuit. Going to make it available in my online store soon a long with a massive update to my first feedback video synth design, the FB-01. More info will be available on my website in coming days.
I have a couple of questions First one, the circuit to adapt the external voltage to the chip is for +5 -12v, i have a semi modular synth that sends out +5-5v signals, while it won't harm the chip, would this difference affect the modulation in a significative way? Or worse, may it damage my synth? And, second question Can i use the same circuit (so, 10k resistor + npn transistor) to adapt the voltage and modulate the other pins from an external voltage? (maybe making a small boxed voltage adapter with mini jacks and that circuit inside would be a good idea to use external voltage by pluggin it directly into the patch bay between 2 mini jacks or maybe adding the input and output of the adapter on the top patchbay and the cv input on the side) (i was also thinking about asking if i can modulate the effects by putting a potentiometer between the pins, but i think i'll just test if it works and avoid bothering you anymore) Thank you in advance for your responses Great video by the way, i think i'll probably buy the T420 mk2 in future ;)
@@renatomarciano15 It does not work as i expected but it does "something" lol I will remake the synth with more customizations in future though, with a custom 3D printed case
Wait, what? Am I losing my shit or did you skip entirely over how to wire the stuff at 7:05??? You didnt tell us what to do with the those pins from from the IC on the red board at all? Why do electronics tutorials alway skip entire sections of the project?
The white wires are connecting the IC to the empty board and them he use the ribbon cable to connect the empty board to the plugs, using the IC diagram that you can see in the video to make three separate rows that correspond at the IC DATA/COMMAND/ADRESS. The four buttons are connected to nothing and act as temporary switches if plugged using the banana cable. I know that it may be a bit confusing, but I recon that a lot of DIY videos are made in a way that you have enough info to start a project but enough shades to make you fuck-up your projects. Sometime you have to work around difficulties by yourself ^^
