Here's a dirty but fun way to get video from oscillators.
A NovaDrone unit has 3 oscillators, each of which go to one leg of a RGB LED.
when you put a phone camera up close to it, or any other CCD camera with a rolling shutter, you get bands of colour.
With AE, it would be simply a matter of putting a resistor in series with each of the R, G and B legs of the RGB LED and getting input from 3 different voltage sources within the AE environment.

There is a big opportunity right now in AE modular and the first person to make it happen is going to make bank!
Analog video synthesisers!
Analog video synthesisers use voltages/signals to affect a composite analog video signal (NTSC/PAL)
Right now the market is incredibly small for these things, you have one one hand the 3TRINSRGB+1C from Gieskes (I own it its awesome) that costs 600$ unless you solder the kit yourself. On the other hand if you go the modular way, there is LZX industries, if you thought the first option was pricy don't dare to look at these prices they're premium prices ;P
(we're talking 1000$CAD just for the case)
Now the 3TRINS uses a mini patchbay like AE modular, which makes me think this is a really good idea for anyone to make "AE format" video synthesisers modules at a much lower cost than all the current product on the market!!

Here's a dirty but fun way to get video from oscillators. Great find, rodney ! Now check this out! I bought a cheap 600TVL FPV CCD camera, running on 5V. One can even unscrew the optics completely (or make it a super-near focusing macro camera with the lens almost unscrewed). I then attached the open sensor to the RGB LED of my Super Warp Generator and played a three-oscillator pulse wave drone with PWM and pitch sequencing through it and watched the video on a small handheld video player with an analog composite video input. Of course the camera is powered by the AE Modular's regular power bus  Here's the Instagram post (click on the arrows to flip through the pictures to the video) http://instagr.am/p/Bzc-8-fIuzy I think I might make this a proper DIY module, with a built in camera glued to an RGB LED - just like a high-tech vactrol! Haha! admin could you maybe move this post and the one before to the video synth thread in the Talk forum? |

wait! that tiny camera actually has a microphone on it as well? for $5... blimey... wonder what crazy uses that might yeald. Indeed! The mic also works simply by plugging the white wire of the camera into the AE Modular. Here's the wiring diagram of the camera:  So yeah ... nothing difficult at all. It just plugs right into the AE Modular and the camera even has a pin header at the end of its cables, so you can plug your AE Modular patch cables in it directly without having to alter anything  edit: More drones! http://instagram.com/p/BzdG4cpozXa |

Those cameras I linked arrived here in Germany in a week. Regarding the ground socket, you can just leave an empty space in your rack and take the ground from the unused bus cable socket. |

Regarding the ground socket, you can just leave an empty space in your rack and take the ground from the unused bus cable socket. there is something untidy about that , that has kept me from doing it up to now... but yr reminder has made me have another little think .... hmmmm, tiny hole in a single u faceplate... short pin cable from the hidden bus socket, through hole and into mini breadboard on the faceplate.. i won’t have to remember/look up which is the ground socket more than once AND i will have 5 ground sockets to play with... i’m guessing this is what you did with yr 2u breadboard faceplate? except maybe with the +5v rail as well? thanks for steering me in the diy direction felix.. |

Tricky, though...video works in a very tight range of 0 - +1V. Feeding an AE signal without voltage rescaling to a video synth module could be rather damaging. I'm not sure if Gieskes' module is expecting 1V signals on its pinpoints, although the fact that it has those is encouraging.

Yes, I put +5V, Ground and Clock on that module's front panel  More drones: http://instagram.com/p/BzfA1kUIQ-u |

Aaaand it’s a module: http://instagr.am/p/Bzflbf_oDxZ Just need to put a front panel on it and mount it in the case. I added an on/off switch because the camera draws 80mA and produces a bit of heat, so I don’t need to have it running all the time in my rack. Here are some pictures: Parts:  Built .. that should fit behind a 1U panel  A little, triple-LED, light gun right onto the open camera sensor!!!  |

That's true, although from my analog video bending experiments, I found that equipment tends to be rather tolerant and overvoltages will usually just overexpose/clip the image. |

And I'm done! NOW it's a module!  I call it "Visual Vactrol", because it really is like a vactrol ... but for video. lol. Front:  There's a cinch socket on top, which can be freely patched from the top left AE socket. Left side inputs: To cinch socket +5V GND (like this I can connect another one of those tiny cameras directly, if I wanted one that is not built in). Red In Green In Blue In Right side outputs: 3x internal camera composite video output 3x internal camera microphone audio output (because why not  ) Back:  In action: http://instagr.am/p/Bzfykp-ohW8 |

Bought a small composite video, car rear-view monitor and mounted it in my case:   I think I could even manage to run it from my +5V AE Modular power bus too, but I might be pushing the power supply to its limits then |

Words fail me! I got carried away in end-of-australian-financial-year retail therapy and added another empty AE rack to sit on the bench silently accusing me until I empty my parts drawer into it, piece by piece!
I love the sharpie pen artwork on your modules too.
