how would i wire in a delay for an actuator? basically i want to make some move in 2 directions, up and over. i want it to move up first then over. how would i wire up the actuators so that it moves the object up first, then after the actuator fully extends have the other actuator get powered and move the object to the side?
make a tab one the first actuator that will push a button when fully extended to activate the second one.

+1, aka limiter switches.
car audio noob since 1984.
i am sure there are many more ways, but you are talking about bringing circuitry into the task.

something like a module of some sort? like a little circuit board kind of set up?
yeah some type of circut like that would probalby be the proper way
problem with having the first actuater hit a switch that starts the second one is now that switch is constanly on, and when u want to close it you'd most likely want the second actuater to closer first then hav the orginal one closed. if the first actuater is hitting th power switch for the second it be hard to close it back.

you would have to do it manually... ask kardain, he seems to be good with this kind of stuffs
a limit switch or a proxy would be the best way to go about it or you can get a cheap plc and do it.
ive seen some cheapy plcs that can handl this thing for less than $300, but thats overkill.
limit switchs are fine.

you're definitely correct. i do want the second one to close first.
so where would i go about find a 'plc' or some kind of module like what i would need? i'm trying to think of a system in a car that would use this sort of a thing so i could just go to a junkyard and get one but i can't think of anything right now.
the plc lets you program logic into it. basically, you can program the controller not to give power to the second actuator until the first one has traveled.
personally,you are better off with limit switches or proxy sensors. im assuming these are going to be air actuated? if you pick your solenoids properly you can do it. again, its been a while since ive played with cylinders and solenoids, but i think its a 2/1 (or 3/2, can't remember which) that you need. basically, the cylinder moves from A to B when an solenoid is energized. it doesnt move back until another solenoid is energized.
you could do it with a timer, but if the first cylinder doesnt reach its position for what ever reason and the second cylinder goes to move... you may not want that.

Allen Bradley Pico controller
Siemens Logo controller
Moeller Easy PLC
These are very low end PLCs (programmable logic controllers). Actually they are the same controller under different brand names. They are not hard to program, but then again I've been doing programming on higher end PLCs for some time. You could probably find them on Ebay. You'd still have to have some type of limit switches, but the PLC would handle the logic for sequencing or timing. The Allen Bradley programming software is the easiest to use in my opinion, but neither is difficult. Also, any of the controllers can be programmed with the other brands software (since they are essentially the same). You could buy any model and then download your preferred programming software.
the other one that you can use is the schneider / telemecanique zilio controller. im pretty sure its made by the same maker as the pico.
you can program via software or by the softkeys and lcd screen on the controller. i can get the zilio for a good price, but then again we have an acount with them at work. should cost you less than $500 i would think.

Programable timer boards
Something like that aught to do the trick. its the only thing i can think of altho i could swear theres a relay that does the same damn thing. but apparently not. and i am almost certain that there is an alarm out there that has a module you can add that has timed functions. let me do a lil more research
