Ultimarc U360 Mod to add rotary function&Top-fire/LED

<< < (8/21) > >>

Bender:
What are you using to control the LED's? Ultimarc's pac drive or GGG's led wiz?

Franco,
thanks so much for the offer, it's much appreciated

Seems like GGG has different single colored ones for .49 apiece
I think I'll grab a few from them to test out

I have a 3 conductor plug, I don't see why I couldn't share the ground between the button and the LED,
but I'm no electrician, so I could be wrong
Getting those to work together and fit in the ball top
That's a whole another issue I think it can be done, but it will take sacrificing a 2nd ball top
speaking of that does anyone know where to get a brass insert that will fit the JLW shaft?
I think I'll have to drill out the old one to get the a button in there

Yeah you would need a four conductor plug for RGB, so far I have only used one of the colour annodes and the cathode in each shaft for a red, green or blue shaft.

You may struggle to fit four LED legs and wires down the bore but it may just about be possible. I countersink my shafts at 60 degrees almost to the thread diameter to give a little more room to get the legs in.

For RGB and a top fire wouldnt you need a 5 conductor plug (if there is such thing) even with a single ground? (Red, Blue, Green, 'Fire' and ground)

Im no electritian either but I wouldnt have thought you would have been able to share the grounds between the encoder and the LED ground seeing as the encoders dont handle much current?

As for LED controllers im using three LED Wiz's and a Pac Drive.

If you are just driving LEDs I would recommend the LED Wiz as you can control the 48 levels of intensity (needed for fading lights etc). The Pac Drive only works as On/Off.

However if you want to run 12v (or even other higher voltages with an external power source) you will need a Pac Drive as the LED Wiz only handles 5v devices.

The LED Wiz is more expensive than the Pac Drive but it has double the number of outputs (32 vs 16). If you only wanted to use a few LEDs/outputs and wanted to keep the cost down you could use the GGG LED Wiz+GP which is basically a 16 port LED/device controller combined with a 16 input encoder.

What are the brass inserts you are talking about? If you stuggle to find some im sure some could be made ;)

I am testing with an LED wiz. Only way to go, I will most likely have 4 of them because each only will handle only 10 RGBs.

I was thinking about a wacky idea, using the steel shaft as the ground. It would save a wire. Anyone think I'm nuts?

As long as all the other leads are insulated with no exposed connections that could touch the shaft, you'll be fine. It's a good idea considering your limited wiring conduit.

Good thinking Batman  :)
