in the exhibition space . Is it possible with q light and what kind of hardware should i look for. some kind of sensors that repond to movements would be preffered .

Hello i am working on an art project that is working with light and i am looking for a way to let the visitors in the exhibiton trigger differrent light events
in the exhibition space . Is it possible with q light and what kind of hardware should i look for. some kind of sensors that repond to movements would be preffered .

hi
if you are able to program some arduino sketch you can do something like
sensor -> arduino with firmata firmware -> puredata -> osc odr midi -> qlc+
like this you can program the behavior of the sensor an light in the arduino sketch
for the sensor i can suggest some pir sensor (but you have to use only cold light because the pir is sensible to incandescent light)

Ofc it is possible... Setup QLC+ on Raspberry PI. Problem with this kind of usage is that out of the box qlc doesn't support any kind of advanced logic on I/O before using the result as a scene trigger. What you can do is use Arduino or any kind of uController (prefferably the one that works on 3.3v so it can be compatible with Rpi) to do the I/O logic and computing of the inputs and than have a dadicated signal (result) that is connected to Rpi and activates the Scene.Asbury wrote: ↑Thu Oct 18, 2018 8:58 pm Hello i am working on an art project that is working with light and i am looking for a way to let the visitors in the exhibiton trigger differrent light events

As a sensor I use the relatively cheap pir's used in burglar-alarm installs...
But !! Be carefull with long cable runs ... 3,3V inputs of the arduino / RPi are very sensitive...
Switching on a 1kW Fresnel induces enough to kill the inputs... on long parallel cable runs that is
PS: I had some zener diodes in place to be sure ... and under test conditions that was fine

All electric machines work on smoke... when the smoke escapes... they don't work anymore

This is a late reply, but figured I would add it for anyone searching for stuff in the future.
Might want to check out the X-keys system from P.I. Engineering. It is a small USB box that you can plug in a bunch of switches of various types. I have not used these, but recently came across them. Not low cost, but they look to be pretty robust.
