I have been wanting to work with stamps for some time now and I believe I have found a few projects that will put them to good use. One idea is a device that will trigger amps on and off. Here is some background;
I work in the A/V industry. I set-up and install home automation systems and whole house audio/video. We build large racks of equipment, many amplifiers.
We use an audio matrix device that has 16 stereo inputs and 32 stereo outputs. So in a house with 32 zones of audio we may have 8 amplifiers, 4 zones each. The zones on the amps are triggered on and off from the audio matrix by a DB9 connection providing +12v.
I need the ability to trigger the zones in different ways depending on the project. Say we have Zone 1 which is the dining room and we have 2 pairs of speakers there. For control purposes we need to maintain it as one zone. The audio matrix when asked to turn on this zone will send +12v across pin 1 of DB9 1. What I do now is build a triggering box in which I set up physical wiring to allow pin one from the matrix to provide +12v to pins 1 and 2 on the first amp. In other words 1 zone on the matrix turns on two zones on the amp. This works well but if zones are changed or speakers are added in the future I need to re-wire the trigger box which is time consuming.
I am wondering what I can do with a stamp that will allow me to do this with programming and not physical wiring. The device I build will have to have 4 DB9 inputs from the matrix and 8 DB9 outputs to go to the amps. There are a lot of connections to deal with here.
What I picture in my mind (keep in mind I am a novice with the stamp) is two 32 pin stamps that use the 4 DB9 outputs from the matrix to trigger relays to send +12v to the appropriate amps inputs.
Does this seems feasible with a stamp?
I appreciate the input.
