hardware with software


hey, i have a question. i work at this radio station and we have a transmitter (obvoiusly). i am curious to know if there is any way to be able to monitor if the transmitter is on. i specifically want to know if it is possible, and if so, how would i go about learning how to do this, to be able to have a website display "transmitter on" if its on and "transmitter off" if its off. i bet there is a way to do this i just don't know how

im not an electronics expert but basically you want a relay triggered by the transmitter control control circuit which is connected to a serial/parallel/game port. you can then read a byte from the port to see if if the transmitter is live or not. once you have the hardware hooked up its a simple server side script to read a byte from the port and generate approprite html.

i think both of these deal with output but im sure redesigning the circuit for input is not hard, you can find the specs of the various ports here: http://www.nondot.org/sabre/os/artic...cationDevices/

/me goes for the obvious...

how about tune the radio receiver to the station and listen? Static == not broadcasting.

But seriously, if it's an FM transmitter you could probably get a tuner card and get some useful info from it via some funky probing...

lol, unfortunately i go back to my non-internet-connected house at uni at the end of september.

ive promised myself im gonna work this year, i only just scraped a first at the end of last year(72%) and im determined to get over 80% this year, im gonna need it cos in my 4th year they hit me with an evil double module 200 page project thingy and i am useless at stuff like that, im one of those guys who spends his degree in the pool hall then walks into the exam and passes but me and coursework dont go very well together.

i'll still be around on occasion though.

heheh i am the same way. and how can you have a non-internet connected house when you're at school? every house off campus here (university of maryland) has cable. i don't think anyone would move into a house off campus without the internet.

i guess the uk is a lot differernt to the states, its only in the the last year or so that people have started to move off dialup. it will be a long time yet before student houses get cable or dsl, most of my friends dont even have phones in their uni houses.
