Cutting Rope at a height

Hey guys, I need to cut down a banner on the second story on a side of a building. The banner is held by 4 string/ropes at each corner and I do not have access to a ladder. What would you suggest is the best way to do this? I thought of putting a scissors on the end of a long stick and devising a string pulley system to operate the scissors from the bottom. Like have the scissors open and position them with the rope between the shears. Then I would just pull on the string to snap them shut. What do you think? Any better ideas?? Thanks!

3 inches of pain

Does anyone remember Gattaca? Well that movie explored the possibility of limb extensions in a fantastic manner. Apparently there's a vanity medical procedure to do this called Limb Lengthening. I'm not sure if anyone in the US does it, but for 100,000+ dollars you can add a few painful inches to your legs in Cairo.This procedure seems reasonable for midgets, or other deformities but for people 5'6" you'd think that this surgery is pure vanity. But that may not be true, a survey of CEO's of fortune 500 companies shows that they are on average ~6' tall. Another research study that followed thousands of people from birth to adulthood shows that an inch of height above the average of 5' 9" is approximately equal to a salary increase of $789 a year.What do you think? Is this vain, or a good way to get around prejudice against average/short and

When Toast Flies

It is not often that I find something so useless so awesome. Freddie Yauner's toaster pops your toasted bread way up into the air with high-pressure carbon dioxide. He is going to try to break his own world record of the highest toaster pop, which currently stands merely at the height of his ceiling. An added bonus of this: if he pops it to the right height, he may be able to avoid the curse of the toast always falling butter-side down.Link

Building a taller lift for my chair

So, I own an  adjustable bar-height stool with min-height of 24" and max-height of 33" and I wonder if it is possible to either   1) retrofit the existing hydraulic lift so I can get 10" more in height  2) Or completely build from scratch a similar hydraulic lift as the one I currently have installed except the new one would provide a max height of about 45"   I would appreciate any tips in accomplishing either of the above listed options please.

Variable height desk: replace hand-crank with some kind of electrical motor

Hi, First time poster here, sorry if I'm misplacing this. I have near zero knowledge of engines, though I understand physics, at least from my civil engineering college years. I bought a variable height desk from IKEA (Skarsta model), which has a 12cm radius hand crank (see photos) that ends in a hexagon shape, h=6mm (so diameter around 6,93mm). This hand crank works fairly easily, needing little effort to crank the table up, with ~45kg of weight on it (it's supposed to go up to 50kg). So basically I was thinking if there was a easy, cheap and safe way of automating this with some sort of electric motor (I even looked up those Lego Technic motors!). Any suggestions? Thanks

Leveling a tree stump

Hi there everyone. So I have a bit of a dilemma. There's 3 or 4 beautiful knotted and dried tree stumps that I pass everyday and I've finally decided I want to drag them back home with me (which is another problem entirely) and use at least one to give my rain barrel some height. It's about a foot and a half in height, and just about thick enough to handle it. My problem is that the top is completely uneven and has been hacked with a chainsaw. I'd need to level the whole thing on top and bottom to make it useable. I just have no idea how I can go about doing this WITHOUT using a chainsaw. Thanks in advance everyone. I'll post photos soonish.

How to avoid CNC crashes

Hey.I am wondering if it is possible to define particular areas on the bed of my CNC machine which I do not want the toolhead to pass over. My setup is an Arduino powered CNC pen plotter running GRBL. I am generating GCode in inkscape. I know I can set a safe height for the tool to pass over work safely but what if that height doesn't suffice. Can I define an area that the tool must not pass through?As a simple example:Before running a file the tool is at the origin. On sending the file the tool will take the most direct path to the first line to cut/draw. Imagine there is an obstacle that would cause a collision if the tool takes this direct path. Can I do something to ensure the tool navigates around that obstacle?I hope that makes some sort of sense :)Any ideas appreciated

Vertically Adjustable TV Wall Mount

I am in need of a vertically adjustable wall mount that would hold a 32" LCD TV and raise/lower the tv with 12-24" of travel. I live in an apartment and am on a tight tight tight budget, so I am trying to dual purpose a TV to be both computer monitor and bedroom television. My problem is that when the TV is sitting on the desk, I have to look between my feet to see it from the bed. It just isn't comfortable viewing. If I were to mount it at proper viewing height from the bed, I would be craning my neck to see it. I have scoured the internet and the only mounts they make like this are as expensive as another TV.  I am a novice at this kind of thing, so the simpler and cheaper the better. If I could mount some sort of track to the wall and use a heavy pin to set the height or something like that, that would be an idea. Any help would be much appreciated! Thank you,  Sean

Question: Best materials to build a meter height elevator (3 floors)

I have a challenge, and that is, to build a 3 floor elevator. The main frame was built using 2mm carbon steel sheet and rivets, and painted blue. The frame, 950mm height, 250mm width. I thought of using doors (two halfs, opening to opposite sides). What I'm lacking is: • the motors to open the doors (already have one for the cabin, which is more sheet); how strong they need to be• the doors; more sheet? They will be on the main frame. And, should the doors slide on a U like tube to prevent them from woobling? or use gear racks weld to the lower part of the door? And, how would I join the doors with the motors, pulleys and belts?. I'm having stupid amounts of difficulty to view how I am to make the doors work. This will run on grafcet, already done too. Just really only need to assemble the doors and its motors.

Rainbow Play Systems - Tube Slide Instuctions/Help Needed!

Hi all, I recently acquired a used 360 corkscrew tube slide that was a part of a Rainbow Play Systems playset. I'm planning on building a fort/play/swingset for the kids, and attaching this slide, but would like to find the original instructions so I know the proper deck height for the installation. Also, it seems like each of the slides 6 sections have the bolt holes labeled (A, B, C, D, etc.), and I assume that they should all be aligned (A with A, etc.), but this isn't the case for each section. Perhaps the previous owner put it together wrong, or perhaps there are different alignment configurations based on the deck height where the slide will be installed and/or how extreme the drop in the slide should be. If someone has one of these sets and slides, and can either share the instructions, or even just look at your slide to see how the letters are aligned, it would be greatly appreciated. Thanks! PS - Here's a link to the slide: Option 19F - 360 Tube Slide

I have a big outdoor plastic closet with shelfs in my garden. i want to place a pc with crt screen inside heating the space in which the pc and screen are to be located is 1/4 m3 (1 m wide x 1/2 m deep x 1/2 m height between the shelfs) or 1/2 m3 (1 m height) but with other objects sharing the space the computer is a pentium 1 (~40 W power). it is intended to be on for long periods with the door closed. the closet stands in a shaded place but air temperature outside can get to 35 C + sometimes. i dont want to cut vent holes in the closet the monitor (15 crt) is off when the door is closed. though i may switch it off and close the door while it is still hot how to prevent overheating ? is a water tank thermostat set to 45 C in the air near the pc (with the 240 V to the pc going thru it) good enough thermal protection ? insects we have lots of ants. how to protect the pc from them ? will the hot air in the closet be enough to distract them ?

(newbie) materials to build a sliding &quot;inverted-L&quot; stand / pole

Hi folks!Just discovered this fantastic website! I have this very cool idea for a 'ible I am working on and cannot wait to put it on the site. For now and as a first step (sorry, I am a newbie!), I am simply trying to build a simple stand with the following "inverted L" shape:- - - - - - - - - - - - - -||||(floor)Think of tje coat hanger in the picture below, only sturdier and with a single vertical pole (and without the wheels/mesh at the bottom). Also, the vertical pole does not need to be telescopic: as long as I can adjust the height of the horizontal pole I am happy. This could be done eg by mounting the horizontal pole on a "tee" fitting; but then how do I make it fix into a given position/height on the vertical pole (and still be adjustable)? (I had a look at this 'ible -- -- , but I don't understand how the tee fitting gets fixed into position: welding?)I am thinking of using pipes or PVC from a hardware store. My big question is: how can I get the vertical adjustment feature using such readymade materials? Thank in advance for any help!James KirinPasadena, CA

Tire Tee

I want to make a tire tee for my softball-loving daughter. I saw the one in the link below and thought it would be an easy (and cheap) DIY. I'd want it to be portable, as her team is talking about practicing inside a school gym when it gets cold and this would be an excellent tool for hitting inside. My thought was to fill a bucket with concrete and stick the pole in it which would be my base. It looks like there's some PVC slipped over the pole with a pin/screw/bolt holding it at the height. If I want to get really fancy, I can drill multiple holes and adjust the height for each girl. The weight of the tire should provide enough resistance on its own. I want to limit any extra resistance from the tee as much as possible. The question I have is about the pivoting tire. What's the best way to set that up? I could have two pieces of PVC connected by a coupler and the tire would rest on the coupler. Or I could secure the the tire to the PVC in some way and when the batter hits it, the tire AND PVC rotates around the base pole. Any suggestions about this? I appreciate any insight! Thanks!
