Turn off the projector

December 1, 2008 | 9:56 am

Hello,
I have an interactive sound installation in front of a building. I want it to run from 16:00 till 23:00 at nights, but there is nobody to turn off the projector, in order to save the lamp, energie etc…
Our beamer is not brand new and does not have an network connection and timer. So, what could be the other options for that?
Thank you very much,
Best,

You could always buy a lamp timer, one of the ones you plug the lamp into and then plug that into a power socket so you can set when it turns on and off. This might not work depending on how you choose to power the projector because it will be outside, it might not like being shut down in this way either.

read the manual of the projector. you may kill the lamp like that if
the fan cannot cool it down when you just cut the power.

shutting down a projector without proper cooling will severely shorten its
life. but with current prices for bargain projectors…

cheap+hackish = learn your projector remote sequence for shutdown and pulse
an IR led to simulate your remote. its a common habit (lirc) with diy home
cinema builders.

pricey+pricey = get a projector that has rs-232/network/usb remote control
options. most mid level projectors has this option.

found this Universal Infrared Receiver Transmitter if anyone is
looking to interface a remote controlled something

hmmm, I wonder if you can interface with a usb IRDA and turn it into a remote.

you could then get it to record the signal sent by the remote and replicate it and sent it out when you trigger it in max.

opinions
?

That’s great, thanks for the info–lots of possibilities there. Would be fun to get one and see what comes out of [serial] in Max, I’m assuming it would be pretty straightforward to work with.

yeah, please, i’d love to know any experiences with this thing

I had purchased a power outlet timer when I was growing some plants to turn lights on and off at specific times, you can find them pretty easily at home depot type stores. They are just little timers that plug into an outlet and have jumpers that you put where you want it to turn on and off.

that is not a good idea. projectors in general can’t just be snapped
off. you need to do a soft switch, through IR or serial. if you just
cut power with a power timer, you’re going to kill your lamp.

I did some searching. and I found that it is pretty simple to convert the IR signal transmitted from the remote and re-send it out.
(more info here http://cyli.livejournal.com/33460.html)

Using an infrared Reciever and an IR Transceiver.
both available from radio-shack for under 5 bucks.

if you have max, you can make that $50 device for under ten bucks.
