Seems to be a good plan Well it seems to be a pretty sturdy design. My only question is, where are the pipes for the WC going to go? you going to run them through the other boxes, straight up and into the bottom of the "foot"? Otherwise, I would say get some measurements, whip out the dremel, and get to work.
What should I use to lift the top cover?? I guess I will need something that can lift around 2-3 kg. And electrical motor would be perfect. Anyone know where I can get something like that.
What about an electic motor that just spins in two directions (slow) What about an electic motor that just spins in two directions (slow), with a wheel with spikes (sorry doesn`t know the name for that) And a list with spikes to "walk" on. Where can I get this??
I really need some help to find a suitable device. I really need some help to find a suitable device to lift my case top. After some calculation, have I found out that the to weighs (1m * 1m * 1 cm = 2.71 kg Aluminium plate) So my top will weigh max 4 kg. An electrical drill is to big and to expesive. What do Bang Olufsen use to open their doors on the soundsystems (I know they will be to small, but it would be help full to understand how it works.)
i would be using servo motors to move that, like in mashies Y2K Bug, you can get some really powerful ones that should be able to life about 5kg
Servo motor sounds good. Where can I get servoes? Any Idea on how to make the lift system, with a servo?
most electronic stores sell them, if you cant find them there, try hobbie shops that have rc cars or planes, they use them for the steering and throttle do you have msn messenger
I have found the solution to my problem Ok and update on my drawings. Big picture This picture displays: - The case open. - Then u can access two 5.25" bays for cd/dvd rom use. - The case closed. - Case number 2( the one on the buttom): - Is the watercooling part. - Two 2*5,25" bays - Will be used by these to objects: - Water tank - Control unit After some thinking I found out that it is easier and cost effective to join the "watercooling part and the control part to one singel case as u can see. For my main problem, How to lift the top of to reveal the 5.25" bay for CD-Rom. The solution will be: - To modify a servo like this : Modify Servo or this one - When modifying the servo it can be used to pull the ropes/cables up as shown on this drawing. What I may need some help with would be how to place the two weels for the ropes on a 3 mm aluminium plate. And where I can get those type of weels. There is a big hole 15 mm radius for the power button to the computer and a small one for the reset button. That will be made of acryl, but I haven found anyone that sells acryl sylinders with those dimenssions. Anyone know where I can get them in UK?
I would favour stepper motors; they're quiet and powerful although they need some simple electronics to drive them. You'd assist them with some gas-filled pistons like the ones that keep the bonnet or tailgate of your car open, the idea being that they are just strong enough to _almost_ push up the case, thus counterbalancing its weight so the motors have only little work to do to lift it and hold it in position once up. As the pistons _almost_ but not quite push up the case, going down would simply be a matter of motors and gravity working together. Basically the pistons are like a counterweight, geddit? Better, but more expensive would be hydraulic pistons or electric actuators (sort of look like pistons but with an electric motor on worm drive built in; designed to do some heavy lifting!). You need to look at some robot building sites on the internet; else look at industrial part specialists or electric wheelchair manufacturers (not the simple ones you see in the NHS but the real high-tech ones you only get privately). BTW I believe B&O use actuators of some sort in some cases, motors with rubber friction drives in others.
yeh pneumatics or hydrolics or even liniar rams. if its only a couple of inches how about this: robart great fun and very stylish
I think using something like an electric motor attached to a long threaded rod that spun to lift the case would work really well like Nexxo said. Although you would probably need to maybe make a hole in the middle of the cases to allow it to fit. I also think it would be able to lift the weight really easily. Making one would be pretty easy. All you would need would be a motor that attached to the threaded rod. Then attach a nut on the rod and place a pipe over the nut (kind of will look like a piston when done, the screw part would be the piston ) and then attach the pipe to the case to be lifted. I built a very small one once just for fun but never used it on anything. Just something to consider.
Cut a rough circle out of a normal sheet of acrylic, mount it to a drill or dremel, spin it and use a file and sandpaper to shape it. I've tried the threaded rod approach on a project of mine and failed miserably. The problem was that the rod came from Home Depot and its threads were not perfectly shaped. The weight of what I was trying to move was heavy enough that the nut would bind on the threads, overloading the motor. It takes a special type of rod to do this type of project.
prankster has the right idea for a cheap solution. its called a worm drive. damn easy to make and very very robust. just takes a little time, but can do super heavy workloads--ive seen 4 little inch-long motors (from little race cars or something) lift up a person, as part of a science class thing. rack and pinion is the one that you had the drawing of... info: HowStuffWorks
