AV synth / efx box

[htor]

hello all!

i’m currently making a box that will contain ideas from different projects:

• the GBS-8100 video VGA feedback synth+glitch box from Lofifuture: LoFi Future - Circuit Bent By Design
• the excellent two_comparator and rupture composite video effects by @cyberboy666: GitHub - cyberboy666/two_comparator_effect: analog video posterisation effect - adapted from a rob schafer design GitHub - cyberboy666/_rupture_: simple analog video glitch circuit - adapted from a karl klomp design
• and the James Connolly VGA2audio and audio2VGA cables to incorporate audio/oscillators: https://jameshconnolly.com/projects/rgb-vga-volt/video_to_audio2014.pdf https://jameshconnolly.com/projects/rgb-vga-volt/audiointovideo2014.pdf

so far i’ve built the two_comparator and the VGA feedback circuit and the enclosure:

more stuff will come… hope you like it! cheers o7

Finally received some parts in the mail. Box version 1 is now finished!

If only I could digitize the output properly with my capture card… Something is not right…

re: capture card not right

looks like the capture encoding is MPEG and it can’t handle all the pixels changing so much. yalls should probably use a phone app/other rescan technique for best results, especially if yr working with DIY circuits

Thanks Andrei! Will definitely try rescanning with a video camera. Sounds more fun too!

In the meantime here are some stills:

Managed to do a half decent capture by tuning some MPEG settings in OBS and using the other cheap AV upscaler I have:

Still curious how this would look if rescanned…

I Whole heartedly approve! Loving this combo of projects in one, looks like a fun setup!
