Dear list,
I want to build a dimmer of 7 lamps which is controlled from pure data. Basically, I need to control AC power from 0V to 220.
Is there any hint how to start it building, what I need for it?
Thanks in advance: Popesz
hello,
the keyword to look at is "DMX"
you can buy/use/build usb to DMX interface, and a DMX dimmer.

Sometimes there are even very basic dimmers that even take MIDI as control signal.

I have found this one:

I guess it does the job.

It will only switch things on and off, not dim them. For that you want something with triacs or scrs like this: https://www.quasarelectronics.co.uk/Item/velleman-k8064-dc- controlled-dimmer-kit or

Looks good. You could control it with an arduino via Pd's [comport].
The raspi's GPIO is not enough? Is the arduino still needed?

One or the other should work. If you can run Pd on the pi it would be even
better.

I do think so, because precise interrupt handling is needed. Also (even with an arduino) don't expect a very fine dimming: 100 different values, linearly spaced between 0 and 100%, reading the firmware they provide, sketch #4 ; better firmware is possible though, but quite a hard work...

What kind of load do you need? The Krida you linked to one has 2A per channel. http://www.inmojo.com/store/krida-electronics/item/8-channel-ac-light-dimmer...
If you need more, this one has 4A per channel, but you need two of it to reach 7 channels. More expensive, but no high voltage work required. https://www.thomann.de/de/botex_mpx405v.htm

If you go "future" and will dimm LED lights, then use a PWM dimmer like this one: http://www.digitallighting.com/animationfolder/PWM%20Dimmer%20repeater.htm

I plan to control neon flex, max length 28 meter. It is LED based light source with 220V power changed to 24V DC. I just asked the producer about the amper it can have on such a length. Soon I am back.
Thanks for the hints anyway.
