VIDEO FACE [AVM-312]

Art that makes images and allows for interactive play…

One of the projects I built for Maker Faire Milwaukee in 2019 was VIDEO FACE [AVM-312] which is a companion piece to AUDIO FACE [APC-320].

This piece came about because my sister gave me a box of old security cameras. Specifically, analog video cameras. I brought them to Brinn Labs and hooked them up to one of my displays, and they worked fine. They just need a 12 volt power supply and they have composite video out. If you mix the two signals from two cameras together into one output you get a garbled and mixed signal, but if you add in a resistor and potentiometer, you have a way to control the amount of signal that the second camera leaks into the stream to mix with the first camera! (It’s an analog video mixer.)

I considered adding resistors and potentiometers to both cameras but for a standalone exhibit that would have allowed people to dial it down too much and the projector that was connected would probably have gotten confused and lost a recognizable signal and just shown “NO SIGNAL”, so I went with one camera full strength and the other variable.

Construction of this was very slapdash, using scrap wood I found at Milwaukee Makerspace one night. As yes, it’s supposed to look like a face, I mean, it’s in the name, it’s got two eyes looking at you, a nose with controls and a mouth, sort of…

During Maker Faire I had it hooked up to a projector that had analog video input. (Yeah, those are probably getting harder to find, but I have some interesting old equipment.) For other events I just used one of the small television sets I have on hand.


I loved doing these quick and dirty interactive projects, back in the old days, you know, before the pandemic.
