Retractable door screen

Hi, It's just coming on to nice warm weather here in Australia and the flies are pretty bad. We have an odd situation with our front door in that there's this wooden beam supporting part of the roof that comes across low. This makes it impossible to have a screen door that opens outward (the main door opens inward). My son suggested that we get some sort of retractable screen, but they are so $$. Does anyone know of instructions for how to make your own? Perhaps something that retracts on a vertical roller on one side and when open, it seals tight on the other side with a magnet strip. Thanks, ebb_AU

Retractable mount for stepper motor

Idea for a Knex retractable sight

Ok, I had an idea where There would be this gun. The sights are hidden in the top of the gun, but can be exposed by removing a rod from the assembly. The sights would go on top of the barrel, would be powered by springs, and have a stop. The gun would look like it had no sights, but the sights would pop up when you removed a bolt is the idea. Unfortunately, to make such a gun, It would require a lot of parts, and the gun would be very big, but I'm just throwing the idea out there.......

want help with a possible future steampunk instructible

okay, so i want to make a steampunk contraption.  at first it was going to be a spring loaded gun like the derringer thing in sherlock holmes but with a huge gun (i actually have feasible plans in my head for that one.)  but it drifted off to make an even bigger gun.   i thought, and came up with an awesome idea. a retractable Gatling gun arm.  the gun will move forward, and backward, and will spin around. i made a 3d example to show what i mean, if i can figure out how to post it. [URL=;=MyMovie.mp4][IMG][/IMG][/URL] and if that's the wrong code: what do you think?  any suggestions, questions, ect?

How to make solenoid retract when friction applied.

I have a 12V solenoid that was going to be used in a project with a spring loaded door. It was wired into an arduino project and all was going well. That was until I realised that if the bolt had any friction on it that it would not get retracted when power was applied.I wonder therefore whether there is a simple way of making the bolt retract even when friction is being applied?Alternatively, is there a simple mechanism that could be made where friction can be applied to something else that doesn't add friction to the solenoid bolt itself so that when the bolt is retracted the secondary part is free to move and release the sping loaded door.Any help would be appreciated.

Extending Servo Wire

I need to make a servo wire that extends approximately 4 feet and then retracts to a length of 18 inches or less. There is a risk of entanglement, so the less sag and less loose the wire, the better. One option would be to use coiled wire of the appropriate gauge, but a product such as this is expensive. What are some other options?One idea that I had was to build a wire spool mechanism like that of a tape measure. From what I understand, a tape measure uses a constant force spring to somehow apply a retractive force to the actual measuring tape. Can anyone provide a more clear explanation of how a tape measure retracts? Does anyone have any ideas of how to implement this into a wire spool? Other ideas on retracting a very long wire?Thanks

My classroom projector screen will not retract all the way without considerable effort, how can I fix it?

With several attempts, I can assist the retraction spring by lifting the screen into the storage part and have it rolled up enough that I can rest the handle and... bar, for lack of a better term, on top of a bulletin board.  Is there an easy fix or should I just start looking for funds for a new screen?

Ceiling-hung, Retractible Clothes line or rack for use with clothes hanges

I think this would be very popular in smaller rooms (or one in which you don't want a sagging clothesline running through your field of vision). I would like to hang a sturdy, pipe-like structure (so no sagging under light to medium weight) that I could pull down on a retractible cord/pipe/other to hang coat hangers of washed tee shirts to dry and then retract back up out of the way while drying or not in use. When I was a kid in the 60s we had a ceiling lamp above a table that worked like this; when you were working on something you could just pull it down (click click click) to however close to the table you wanted, then back up out of the way when you were done. This idea would be hung from 2 spots on the ceiling with some kind of mechanism that would allow for pull-down access and then push up storage; some type of pipe suitable for holding clothes hangers would be strung up at both ends and mounted to the ceiling. The "pipe" would then hang level when use at an accessible height, and the "push up" to hang level, closer to the ceiling. Ideally this would be not too heavy as I have smashed my dominant-hand wrist and have limited strength as a result. Help me Mr. Robots! Help!

Canon Powershot SD1100. The lense is stuck and won't retract. Any suggestions?

Hi most brilliant community- Unfortunately, I'm very accident prone and dropped my Canon Powershot SD1100. The lense will not retract. When I turn it on you can hear the motor whirring, but it's not taking the lens in. An error message pops up sayin "lense error, restart camera" which I've done. I have also googled this error have been to many sites that tell you to hit it, or push this button while pushing that button but I can't seem to get it to budge. I did open it up to take a look and the lense is, of course fully enclosed. Most replacement lenses are arount $80 w/o labor. I am convinced that this camera can be saved (without mucho dollars) Has anyone ever taken one apart and more importantly, mended a camera such as this? Can a klutzy but resourceful girl (me) fix this on my own? I have a second camera (same type) that i spilled a melted frosty all over and now it wont turn on. I'll leave that situation for another time! Thank you to anyone and everyone who has any suggestions!

Retractable white roof for passive heating /cooling ?? Dual season roofing idea? Answered

Last summer my top floor apartment was over 115 degrees indoors with blinds closed !  In a recent email to my landlord to report a broken mailbox I suggested the possibility of painting the apartment buildings roof white .  In reward for reporting the mailbox he says I could paint the roof but only above my apartment  . Cool . He says that the insulation was not adequate when built . The apartment has also gotten down to 30' in winter so I can only guess how cold it would get in here without the current black roof.               QUESTION ;  Are there any ideas to help solve both seasonal issues ?   I can't re-insulate because I rent .  I was thinking of a retractable white cover for hot summer days that can be removed in autumn . Or maybe even a white paint that would insulate against cold ??   An original idea was something like Bubble foil but I doubt that would stand up to weather.  Any suggestion would be great .

Getting Power Into A Drawer???

Here's a strange question that I hope someone can answer. I've got a project which has a drawer that has line voltage going into it. My goal is to be able to remove the drawer by unplugging the line voltage. My initial thoughts were using a ribbon power cable but I can't seem to find those. Other two options are coil cord or a retractable cord. In other words, the power needs to stay with the drawer as it opens and closes. Any ideas, thoughts or experiences on how to get line voltage easily from where it plugs in in the back of the main housing and keep it connected within a drawer compartment so I can power a few outlets and other things??? Thanks in advance to the geniuses and experts out there.

Is there a way to lengthen the plastic blade of the basic toy lightsabers (about 12 dollars)?

 I like how this particular model retracts all the way into the hilt, but the blade is very short, and in conjunction with my stature it seems even shorter. Holding the toy up to the light I can see that there is a lot of plastic that is behind the other pieces. Is there a way to utilize this and make the blade longer?

Star wars fans look here!

This is it, the most durable knex lightsaber ever imagined. Each piece doubles up the next creating a blade that will not bend nor break, even with high speed collision. The hilt (figure 2) is also quite detailed considering this is made with knex. The only con to this is that the blade doesn't retract. If you like what you see then tell me. I will make it an instructable if asked.
