Analogue strobe control?

[TomHoward]

Afternoon all

 

I wondered if anyone know if there was a common wiring for analogue strobe control. The strobe in question would be a Stairville PS1500 (el cheapo) - has DMX in, but also has an analogue 1/4" jack input for 'strobe controllers' - there seems to be a standard for these, but I can't find it?

 

I assume it would give me control over intensity & rate.

 

I did a search and found a topic about modifying a non-external control strobe via the 555 but nothing for this.

 

Thanks

Some of the cheaper strobes I used a while ago just used the tip and sleeve and was fired by a low voltage pulse on the tip of the connector. The frequency of the pulse dictated the rate, while the voltage of the pulse controlled the intensity.

So it looks like I might have to put a timer in there - I'll probably just buy a controller then. I had hoped it might have been just a couple of pots for each attribute.

I think it was Anytronics who had an external input as described that needed a pulse, but also a jack that could have a simple pot and switch arrangement to give external control of the internal clock.

this was waaaaaaaaaaaaaaaaaaayyyyyyyy before DMX came along though ;)

That was the one, Anytronics :)

Jack based strobe control: simple 9v battery positive to tip and a push button for a lightning flash (just under the 10v. but does it). Strobe effect: battery/PSU + a 555 timer circuit, but avoid the critical speed (10-15Hz ??) which interferes with brain waves. Use to build them to order for disco rigs (usually to replace the previous one - stolen, stolen, stolen!)
