[Upcoming MBHP_MF_NG module]

Is there a spec sheet for motor specifics for the MF_NG module?

I want to build a motorized expression pedal board.

8 motorized expression pedals with preset positions.

Similar to motorfader activity, just moving an expression pedal.

Servo with encoder, Stepper with encoder?

[Remote Control Foot Sutain, Sos and Exression Pedals For Stage]

Hello Midi-Box.

Long time no sea!! That's what newborn children do!! Let that be a warning to the yonger midiboxers out there. It will come to a point of deciding between midibox.org and children.

There are pros and cons to each, but I am afraid that it will have to wait for another discussion.

Anyways. I am sick to death of cables. They are worse than dirty nappies dudes.

So, I was wondering what success anyone may have had with remote control relays to trigger DIN and AIN on a CORE board.

The idea is to put a transmitter in my foot pedals on stage, and have somewhere in the rackmount a receiver/CORE set up that will sort out the midi.

Any suggestion, abuse or general ramblings welcome.

The Keyboard player in my band has a wireless midi Transmitter/reciever system.

It works remarkably well.

Consider that between 2 cores, one in the foot pedal & another in the rack.

If you want specifics on the midi wireless thing I can dig up the info for you.

[Hot LCD backlight Led]

I think the LED was still getting too much current.

I've done some more tests with this display and I think R4 needs to be more like 80K to limit LED current to 25mA.

With around 47K the LED was probably getting 40mA-50mA which will eventually burn out a LED over time.

I'm sorry I suggested the wrong value... I was using 47K myself thinking it was OK, but a real test with a current meter proves this resistor is too small a value.

I have one of these displays with low-power amber LED backlight if you're interested, I can sell it to you VERY cheap. The LED can be replaced with another colour LED, if you prefer white, for example.

I have a similar problem, unknown LCD no datasheet.

LCD works but Backlight trimpot has no effect (full on all the time)

I Like the "adding resistor to calm it down" idea.

It seems like adding the resistor to the side of the LCD light would be easier and I wouldnt be damaging my cores traces.

The back of the LCD LED connectors show "K" and "A" which one would I put the resistor on?

Thanks for any help
