hi @jmsiener - i have one of those hdmi to csi bridges, but havnt tried it yet (with recur)… maybe it works , or can be added in future updates. also there are quite cheap hdmi to usb dongles that many people are using as input into rpi (including recur) , or composite to usb ones like easycaps also work as video input , although bit glitchy

I’m glad I read through this! I’ve only got a few Raspberry Pi 4’s laying around so I would have wasted a bunch of time trying to figure out why they wouldn’t work

I haven’t looked into running openframeworks on the RPI in a while I know plenty of smart people are trying to make it happen.
rpis are so rad

to be clear, most oF stuff works great on pi 4, the issuee is with gl stuff which renders shaders a bit of a wormhole to work with. unfortunately shaders are kind of the killer app of doing video processing on pis

Hey… I am trying to use the Rpi image for Scrawl, Spread, Spectral_Mesh etc. but when I run the .sh files to run anything other than Scrawl it runs in a small window not fullscreen - what am I doing wrong? Is it because I’m using HDMI?

It may be. I’ve never tried using the HDMI out instead of composite
My CRT is in storage at the moment so I’ll have to give it a go when I can get that out. Unless anybody has a suggestion for getting the others to open the same size as scrawl?
Recently became aware that resources exist to put together a DIY version of Critteri & Guitari’s EYESY video synth using a Raspberry Pi 4. (PIESY? DIYesy?) It’s the same OS, so all the functionality of the original should be there. Just needs a PiSound hat for audio input and a midi controller for adjusting parameters.
The EYESY’s always been something I’ve wanted to get my hands on but haven’t been able to afford, so this should be a fun build. I think many people here would dig knowing that this info is out there:

Here’s another guide for the PIESY build which features a much cheaper AudioInjector sound module instead of the PiSound (~$23 vs ~$100). Probably the way to go for the most affordable EYESY.

I should see about getting this running with a HifiBerry DAC+ADC, since that’s what I have. The raw output of the Eyesy has always looked kind of samey and uninspiring to me, TBH (and I’m sure there’s plenty of potential for more interesting stuff, I’m jsut talking about the demos I’ve seen), but it would be useful as an input source into the whole network of parallel feedback loops and things my setup’s built around.

Would also be interested in this potential compatibility, as well as if there’s any performance differences of running EYESY OS on a Pi3 versus a 4, since I’ve got a spare VSERPI unit with a HiFiberry hat already on it and would save me from buying an audio hat for my 4. Shame that it’s still such a pain to find new Pis in general, gotta make some decisions about how to best use the handful I’ve got. Agreed that the EYESY on it’s own isn’t that impressive from the demos, but as a tool for mixing in audio reactive shapes and patterns and stuff, it has cool utility for holding down some dynamic elements during live shows while part of a larger chain.
Hopefully the lower barrier to entry with DIY builds will enable a more active community of people sharing custom patches and stuff. That’s honestly the most exciting part about the EYESY to me.
I think the Hifiberry hat should work on the Pi4. That’s my plan for now, anyway - take it off of the Pi3 that I was running AutoWaaave on (I’m probably going to use a different VSERPI program on it for a while, and if I reallyneed audio reactivity the audio input on the capture dongle works well enough even if it’s noticeably less responsive than when I use the Hifiberry) and the Pi 4 is going to be a multi-use thing that I can swap cards on depending on what I need it for.
I don’t see any reason why the Hifiberry WOULDN’T work, as far as I can tell from skimming the links above, the audio interface part of it just boils down to “set up your interface according to the manufacturer’s instructions, and then disable the Pi’s onboard audio and make usre your interface is the default.” I’ve got a buch of stuff to get out of the way before I have time for that, but hopefully in 2 or 3 weeks I’ll sit down and see what I can do. If I like it enough, maybe I’ll track down an Arduino Nano and make a little USB controlelr that copies the layout of the official Eyesy, rather than using a Nanokontrol where 75% of the controls aren’t even necessary.

Also trying to think of adequate solutions for a midi controller that doesn’t use more space than it needs to. Was thinking about trying my hand at remapping the knobs on a Korg Kaoss DJ that I don’t use much anymore. Haven’t ever tried going in there and messing with MIDI CCs on any device except a NanoKontrol 2 so not sure if it’d actually work but here’s to hoping that the kaoss pad on it might be useful for implementing some crazy fx with a PIESY, at the very least on the audio reactive end if it’s too much of a pain to automate the kaoss touchpad presets to send MIDI out commands.
I always used a 16n for midi control with Eyesy on my fates. Easy to remap, big ol faders, easy to remember what’s assigned where.
I’ve got some Nanokontrols and a Livid Code 2, and both are way more than it needs (plus the Livid is very nicely built but the encoders are stepped, and it’s something like 24 or 36 very obvious steps per rotation, so it’s not really that great for performance, it’s more for tweaking things accurately and carefully.
I like the idea of a box with the same basic form factor of the commercial Eyesy, except it’s just a USB controller. But in the medium term I’m not going to get around to it any time soon and I’ll probably just use a Nanokontrol until I’m so used to it I don’t care.
Maybe the forthcoming 8Mu device from Music Thing Modular: Bogdan Raczynski on Instagram: "This is the 8Mu midi controller by Music Thing Modular, aka @tomwhitwell. It's smaller than a cookie. There are 8 faders, 8 gestures, and 4 buttons, which is a lot of control! It has a perfect weight to it, solid but not too heavy. Learn more at https://www.musicthing.co.uk/8mu How would you use it? #eurorack #modularsynth #electronicmusicproducer #iphone13promax"
(the link has a video that shows it a little bit, btw)
Despite it being from MTM it’s not a synth module, just standalone, I think. It doesn’t have 1-to-1 controls for the Eyesy, but maybe it’s close enough? (And it’s so tiny and cute!)

Seems pretty cool but also does a lot more than I would need, if I actually do this I’ll just take one of the existing basic Arduino MIDI controller projects and stick it in a case with a few buttons and pots.
When did bzzzbz get added to the list? I just don’t remember it when originally going through this thread. Has anyone had a chance to try it?
Is this wiki only for open source hardware? If not I came across these two projects recently:
