AV synth / efx box

hello all!

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

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!

No problem at all! Keep up the great work!

Finally got around to implementing the LoFi Future circuit bend for the GBS-8100 for some more glitchy aestetics. Added 3.5mm jacks for patch points. INCREDIBLY fiddly to solder to the SMD chip legs… so I gave that up. BUT I tried soldering to the vias underneath as recommended and managed barely to get my thick ass wires connected without them just disconnecting. Hot glued to eternity. Phew!! Never doing SMT by hand again, hah!

I think It’s sort of done now

nice work!

one tip i discovered for doing smd rewiring work (if you do decide to try it again!) is to use this kind of Enameled Copper Wire (think im using 0.4mm):

i use it with one of these Mini Handheld Grinder Engraving Pen Tool:

although im sure you could scrape the enamel off the ends another way like with a craft-knife or something similar.

you just strip some of the red coating off at the end - solder this end to the first point… then aprox length needed and cut the wire and strip enamel off other end and solder that…

its easy to bend but also strong and fine enough to connect easily to smd parts…

made a huge difference for me switching from that tht wire with plastic coatings
