ITSMOKED, I can appreciate your frustration at my dribbling out info, but it's not because I have a great idea, it's because what I'm trying to do is not S.O.P., so when I tell people what it's really for, I get a very MUTED response, if any response at all! So, PLEASE, forgive me for dribbling...

FLOL!!! Sorry for the sea of questions from me; I really like your "Scotty" remark! Skogs, the system will have the actuators moving back and forth constantly, but after an initial engagement of full throw and relatively static positioning(approx 450 N), the units will move back and forth only...

controlling panel movement.

Here's the basic specs on the Linak actuators: Max. thrust: 750 N Max. Speed: 50 mm/s 12V or 28VDC I only need these units to have a maximum 'throw' of two inches fully retracted to fully extended. Does this info help, or do I need to find out more? Thanks!

I'll take the more expensive, but easier route of one power supply per. The electronics hooking up to the actual power supply still boggles me, though. Ah well, a searching and a studyin' I go!

I'm thinking one power supply for each actuator mounted closely to each unit would be best, but.......what is the overall controller to which the stick inputs to? Do I run a standard PC board with a subroutine that simply maps the stick's patterning? Should I switch over to a computer forum to...

OK...I'll get the Linak units with the installed pots, but now, this power supply issue.........LOL!

Can you elaborate on "hefty supply"? Are we talking power, physical size, both?

As opposed to their description of the potentiometer they offer: "The potentiometer is used where the absolute position of the actuator is needed." So, which do you folks think would work best? They also offer a controller board which can work two actuators at once......is it possible to link...

Here's their description of an optical encoder that can be rigged for the actuators: "The optical encoder is used for positioning and servo control of an actuator."

I'll go back to the Linak site, and see what they recommend for accurate feedback control...mayhaps they have units with such controls already installed. The unit I have for testing does not. I'll report back with the info they give me to bounce it off of you folks.

I can order the Linaks with pots built in, but I'm not sure that is what is needed for accurate feedback. The application is relatively high-volume with numerous continuous position changes, but very little structural load. Not sure what you mean by non-volatile load; my only concern is that...

The units are Linak medical bed actuators, run on 12 or 28V, usually run by a hand-controller and usually without installed potentiometers. What I would like to do is operate four of these units with some sort of controller/power board and a standard PC control-stick so that they mimic the...

I'm working on that form on my model now, thank you.

I wish I could find one of the bellcrank configs. I must be looking in the wrong places. I just keep finding the same sliding tray units. I will, however, try to rig up the method you just stated on my model......might work just peachy! Thanks!

Been there, done that...they all have sliding servo trays which, at least to my eye, are not applicable to a scaled up, true mechanical version since my ship would not have servos. But, I'm still open to thoughts, if you'd like to eaborate further.

On my experimental tailless biplanar aircraft, I am getting ready to affix the elevators, drag rudders and ailerons with standard cabling and control stick, but not by choice! Now, initially, I wanted to make use of a computer-controlled/actuatored elevon system, just like on an R/C flying...

Here's the skinny...... 13B rotary racing boat engine turns at 5252RPM ONLY!!! Power is adjusted by mapping turbo boost. Need inline(reversible rotation, OK)2:1 speed reduction unit design that can handle 400-500HP@5252RPM. Current units available can only handle about 300HP at the...
