Title: Interface Strobe Light with PC.. any thoughts??
Post by: JK99 on March 17, 2003, 07:51:26 pm

Hey guys.

I recently built a strobe light from one of those electronic store kits to use with the video/mp3 jukebox side of my cabinet.

I'm wondering if anyone has any thoughts on how I could interface it with a PC and custom write software to control when the strobe is turned on and off.

The jukebox software I use is written in VB.

I was thinking more along the lines of making something that will 'flick' on the power to the strobe when there is a trigger received from the PC. Say via the COM port.

Any help, suggestions, thoughts.. would be very much appreciated.

Cheers guys.

The serial port takes a bit of electronics to decode an output bit stream.  On the other hand the parallel port needs a minimal amount of hardware to interface to.  Here is a link to info on interfacing to the parallel port.  There are many other links re parallel port interfacing if you use a search engine.

Thanks mate

Nice info on the website

In particular this link

http://www.xs4all.nl/~sebdehne/pp_powerSwitch/switch.html

Would do exactly what I need.

I'd be wanting to control the on/off process using VB. Does anyone have methods of controlling the above device using VB?

Cheers

Sweet. I'd be interested to see what ya come up with.

I bought all the bits and have built what I think will work. Yet to test. Still have the 240V side of things to do from the relay, that shouldn't be too hard, assuming I dont fry ---my bottom---.

I also managed to get the necessary stuff to intergrate it with the video jukebox so if all goes well people will be strobing to the doof doof.

If you could figure out a way, via serial or parallel, to control an output (it will involve special wiring and coding), then use a relay or triac circuit to control the light (you will need to use the +5V (or +3.3V) output of the computer, to drive something that can switch higher voltage (probably 120V or more), which powers the strobe.
