Hello! I am DJCRAZYFEELINGS. I make juke and footwork music. I’ve been experimenting with the “Archer Video Enhancer” schematics I’ve seen floating around on the internet. I’m trying to develop easy to use performance pieces for music, rather than purely exploratory stuff. I was a pretty mediocre electrical engineering student who focused in digital signal processing, but now I’m really enjoying learning the basics of electronics! Wow there sure are a lot of data sheets to read! I have a lot of artist friends who like my little doodads too of course and I enjoy being a conduit to the technical world for them. Nothing of note to share yet, but you can find my music and album art made with some minimal glitching here STILL CRAZY | DJ Crazy Feelings
I have LOTS of questions to ask and hopefully I can help with some basics.
We also just released a super cool video synth app called Chromatose that’s audio-reactive and MIDI enabled… have you heard of it? It comes with a bunch of pre-built patches and HD/4K output that let’s you connect to any screen via HDMI.
Very impressive results, and you can build visuals from scratch, share your patches and remix other people’s creations.
More info on our website www.chromatose.app, and we’re also on Reddit and Discord if that’s your thing
I registered an account ages ago (davidw), but I never got past lurk mode, but often inspired by everyone else’s posts!
My name’s Dave, and I make an app for VJ’ing for iOS (GoVJ, https://govjapp.com). I got into VJ’ing back in 2004, when a very good friend asked me to look after the mixer for a few mins while he went to get drinks at a club night he was running. 45 mins later he returned (“I thought you were only going to be a minute…” - “You looked like you were having fun, I’ll leave you to it for a bit longer!”). Needless to say I was bit, and the bug has never left me since.
I’m based in Wellington, NZ these days. I don’t tend to gig as a VJ, but I still play around for myself and I have a stack of video art ideas and projects I’d like to exhibit at some point.
I work on my app, and some smaller iOS video filtering apps and tools in my spare time, very much a labour of love. I’ve also been putting together a mixer based around the Pi 5 (very much Edirol V4-like), which I’m either going to open source or see if I can support a more established project. I’ve also been trying to pick up a bit of audio, and like noodling around the MC-101.
I love mixing to breakbeat, drum and bass, and anything with a good baseline. I’m somewhat obsessed with playing with video feedback, black and white with strong colours, and luma keying. Very much influenced by the early 2000s and the V4.
Anyway, glad to be here properly - it’s a lovely community!
@bsom at the moment it’s a C++ application, pulling from two camera/video stream inputs using V4L2. It brings each frame into a shader, and from there it can blend them and display full screen.
I started off experimenting with HDMI to CSI converters. I found I just couldn’t get a compressed format out of the adapters, or direct to GPU feed from the drivers, to give me enough FPS.
So I switched to HDMI->USB converters, and found with ones giving an MJPEG feed I could get what I wanted.
It’s rough and ready, no MIDI control (I’ve just been testing with keyboard presses)
yeah i’m probably going to be working some more pi 5 projects starting at the end of this year/beginning of next year, good to see that theres someone having success over there.
hdmi to csi stuff i played with only a little bit, but big headaches trying to get things into a decent gstreamer pipeline for c++ → shaders
was having too many issues with trying to port all my old raspberrypi stuff directly over due to the new graphics stuff in raspbian in the 4 and up eras. which version of GLSL are you using for your shader stuffs?
At the moment, I’ve been running in OpenGL ES 2.0, via SDL… and the shader code for the cross fade is incredibly basic, so I haven’t gone too deep into any of the newer stuff at all. All very much initial first steps!
I’m not a huge fan of the Pi5, after you add all the accessories it’s not particularly cheap. You can get a decent micro PC with an N150 CPU, which has Intel UHD Graphics 730 for $130.

Yup. It’s another reason I’ve been happy to look at HDMI->USB capture dongles for my mixer project. The executable I’ve got should just work on x86 linux installations too… I like the idea of recycling old machines into this purpose!
