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!

Hello, I wanted to know if there was a way to build a laser height (measurement) gauge that can measure to .001 or .0001?

Hi, Is there a way to control the height of the quadcopter using the MPU 6050. I know that the sensors i.e. accelerometers and gyroscope measure the orientation of the copter and stabilizes them but how would u measure or like control the height of the copter? Is the controlling of height depends on the IMU unit of completely on the throtle provided to the motors?

 Ive been interested in building a spring pole lathe and have noticed many are about 8 feet tall. Im planning on using a bungee cord as the spring so as long as theres room for the spring to stretch would 6 feet work as well. Thanks

Going there tommarow so hurry up if you can answer this one

I want some ideas that you may have for a carrier. background: I want to bring my Dog on an airplane but he can't ride in cargo because there is a summer ban on dogs during hot months. I must fly before the end of the ban. The airline will allow a dog in the cabin in a soft carrier, if the dog and carrier are less than 10kg. My dog is 7kg so the carrier can be up to 3kg. It must be 27cm high 40cm wide and 55 cm long or smaller problems: the foot print is fine for my dogs they could lay down comfortably, but the height is small. I want to make a telescoping carrier so it can fit under the seat on the plane, but can open up for comfort in the airport and when moving. Any ideas are welcome and I'll post it as my first instructable once I make it thanks http://www.aircanada.com/en/travelinfo/airport/baggage/pets.html

How long does a pendulum need to be for its time period to be equal to the time it takes for a falling body to drop from a distance equal to the pendulum's length? A general equation as well as a specific solution for Earth surface gravity would be appreciated. With this, I would be able to establish standard time and distance units even if trapped on an island without any instruments other than what I can make from available materials. I'm sure I'm the only one tired that happening so often. Of course, I'd still need a way to establish the gravitatoinal constant if stranded on another planet...

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 people._BGvia:boingboing.net and http://men.style.com/details/features/landing?id=content_6838

This is the closest thing I've found yet: http://www.ergospec.com/products/retro_lift_systems/retrofit.html I have been tinkering with a crank/cable idea, maybe counter-weighted; nothing good yet.  It has to raise/lower about 18 inches smoothly and with good stability.  Manual cranking is preferred - electric motors or hydraulics seem too complex/expensive.  Thanks! Just uploaded a photo of the desk. One more note - if I were stating from scratch, I might look at one of these: http://www.geekdesk.com/.  But I like this desk, just want a bit more flexibility (maybe even slide a treadmill under one day if I can raise it even further)

Is there a way that I can control the height of the quadcopeter using the MPU 6050? I know that the accelerometer and the gyroscope are used to measure the angular acceleration and the orientations respectively and stabilise the flight. But how would you measure the height of the quadcopter?

 I would like to make a height adjustable wash basin for someone in a wheelchair. It needs to be capable of being adjusted with one hand and must be able to lock in position. I already have the flexible plumbing supplies and waste fittings. I know that it can be done with electrics but am looking for a cheap alternative. Thanks.

I want to raise the height of my office chair, about 4" or so, but I don't know how to do it. The piston is already maxed and its still too short. Does anyone have any ideas on how I could accomplish this?

Seeking a DIY solution for building a height-adjustable table. How best to motorize/mechanize/hydraulicize the lift apparatus? I'd like to do this with a 2'x4' (or larger) writing/work surface. I'd also like to do it with a folding triangular IKEA "Lokka" table.  I.e., shorten the legs to make it coffee table size, but lift it back up to regular height.

I want catalog my collection of inkwells, including the dimensions of each object (length, width, height, diameter). The largest size is 50 cm. I wonder if there is a device that measures all the dimensions in one time, whether or not electronically. If not, do you have suggestions so I can make it myself? All ideas are welcome.

Hello everybody, my name is Susanne. I recently moved into a very small but very high apartment in Barcelona. The ceilings in the entire apartment still have the original beams and are approx. 4.50-4.75 m. I am looking for suggestions/advice/help on how high to build. I have been doing a lot of research online already and have been unable to find any loft bed at a height of more than 2.00 m but would love to hear from anybody who has ever had a similar project or can think of a good way to work with height as oppose to space. In addition, I cannot seem to be able to find pictures let alone plans of platforms large enough for a king mattress and then some. I am really looking forward to any suggestions you might have!!!!All the best from beautiful Barcelona, Susanne

I need to climb my wind gen tower a couple times a year,(about 55 feet) my knees get wobbly after 25-30 feet. Then I cant let go to do any work.

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

How many of you are willing to climb to a transmitter tower? Are you brave enough? Watch the video and share your thoughts.

Ok, I am only a freshman in high-school so I have know idea how to determine how high an object will travel at a given weight and size.  Does anybody know what this math is called and were I can learn it.

Don't know if anyone actually has similar problems or if it is just me again...Anyway... :I had a bad block in one of my nozzles and no trick was able to free it.Only option left was a full teardown, burning out the nozzle and cleaning it all before assembling.But of course what followed next can also happen if you just took or a nozzle off or replaced it for a different diameter.I did the bed leveling and noticed that suddenly the cleaned nozzle was slightly lower than the other nozzle.And I did not even tighten it up yet as I was waiting for heating up to finnish.Wasn't much of a difference, just enough to be noticable during the leveling.Printed fine until I tried a lower layer height :(Printing with the lower nozzle was fine.Printing with the higher nozzle and the lower one would in some places bump into the printed layer.If you had this happen to you then you know it only gets worse from there.Won't bother you with the long story of failed attempts to get both nozzle really at the same height...I cleaned the outside of bothe nozzles, heated them up and retracted the filament so there won't be any oozing onto the clean nozzles.Once cooled down I used a sheet of fine (1000 grit) sandpaper for the "leveling".With just a tiny bit pof pressure (adjusting the bed screws) I started to sand down the lower nozzle.Once the paper started to touch the higher one I had a look and continued until I had a clean and flat finnish on both nozzles.A it of polishing compound onto a business card and as before I used it to polish the nozzles during a fake bed level operation.Why didn't I do this earlier?The prints come out now with a surface finnish better than ever before.And how would have though that 20 odd kg of filament would take a toll on a nozzle? ;)

Also, how do you completely REMOVE your profile picture?

When I was working in tech support many moons ago, the office had these great adjustable desks. If you wanted to stand up while working you could raise the keyboard and monitor up to a standing height and if you got tired of standing, they would lower down. There was a motor that did the raising and lowering on those desks. I'd like to make something similar in the simplest way possible. Bonus points if the solution can be placed on top of an existing desk and still work.

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.

... Does anyone know a sensor that detects the height of your hand above a given point? ... ... Or does anyone know a laser device that can detect the position of the hand above it? ... >.. I want to apply it on my Laser Harp idea, to control the Volume of the speaker. Mainly the idea is, the position of the hand above the device that produces a laser line will control the volume; if in high position high volume, if in low position low volume, etc. >. Tnx if you guys can comment, suggest, advice. XD

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  

I want to make a loft type bed for my daughter, with a desk / dressing table underneath. However, she is still quite young, so I dont want the loft bed too high at night. I want to be able to move the bed platform up and down to a high 'out of the way' position for use in the day and a low position for sleeping (sort of  'just above the desk top position') But I obvioulsy need to be able to move the bed up and down on a daily basis, so I need something to achieve this. I am looking at what mechanisms people might think suitable - tracks with linear actuator or gas struts perhaps? with obviously some sort of locking device. Any ideas guys?

I have this aquarium 60x30x30 cm. I wish to setup a waterfall in the aquarium. Now the depth of water in the aquarium is to be approx. 2cm and the height of waterfall is to be approx 10cm.  I am looking for a pump design which could work comfortably in that water depth.

I have a 3 month old Pharaoh Hound who can (when she's an adult) jump up to 6' high. We live in a wooded area with lots of little animals like squirrels and rabbits. I'm afraid she'll catch sight of something and hop over the fence and take off into the woods. I don't really want to do an electric fence unless it's a last resort. She doesn't stay out for long periods, mostly just to go to the bathroom and when we're hanging out. Bushes are also not an option because A) I don't have the money to buy ones that are tall enough and fill the entire length (about 120') and B) There's gravel around the fence and not good for planting. What do you think?

Hi there I'm looking to come up with a solution for the boot of my car so any suggestions you can come up with are welcome!  http://www.rica.org.uk/sites/default/files/cars/Boot/5035.jpg  I have a Labrador and would like to have a divider/container for him in this boot, so effectively one side of it would be 'his'.  I would like to have the parcel shelf/cover able to be down as per the photo so that anything in the other section can be hidden from prying eyes.  The crate we have at home is too tall (26") and to get a crate with the right height (20") the crate would be much smaller in length and width and wouldn't be suitable for the dog especially when travelling long distances. We had a pen for the garden when he was a pup but it's too tall also. the dividers you can buy require a backseat grill effectively to be purchased alongside it so it attaches properly - adding cost and also losing my parcel shelf/cover capability. Any suggestions folks? Thanks in advance!  

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.

I need help on building a small 6 x 6 in lifting base. I'm trying to build a small lifting base to lift up a network camera to a certain height and then turn off once it reaches the desired height. If someone can help me I would be very grateful. Thanks Ecusta

I'm trying to design a sobwoofer box. I have a single sheet of plywood (and some smaller wood for a skeletal structure) and want to utilize as much of the wood as I can. By my estimate a single sheet cannot create enough volume for my speakers (believed to need 0.6 cu/ft to 1.25 cu/ft according to Alpine but online sub box calculators say it should be 7.9 cu/ft.

        The stratosphere (STRAT  uh sfihr) lies above the troposphere. It extends from about 11km to 50km above the earth. In the lower part of the stratosphere, the temperature does not change with height. But, in the upper part , temperature increases with height.  At 50km, the temperature is about 7o/c.          Air in the stratosphere is dry and thin, and there are very few or no clouds.

Hello my friends my name Mohamedi need sime help to my arduino project.itcontains an arduino,keypad and lcd.its about IMC(indice de masse corporelle)to input the weeight then height and mesure the IMC.which IMC=weight/height*height.actually everything was fine.i can input nulbers with the keyoad for the height and weight but when i d like to see the result i mean imc value it showd on the lcd ilc=-1.00 its like don t use the value what i put with keyoaf.plz i need help and i will send u later my arduino code that i made it by myself.thank u friends .

Hey, could someone please make an instrucable which enables your average person to make a tripod which can fit in ones pocket but expand to full standard tripod height when pulled out? Large tripods are too bulky to carry around, but small tripods aren't very practical for taking pictures from the right height.

Molds, iron/wire gauge, how deep I must sink them in the dirt (semi-soft soil) and how it is supposed to be the foundation. Also the "specifications" for the concrete like which and how much sand and gravel to use with the cement note: they must have out side the ground 3 to 3,5 meters in height, that is about 10 to 12 feet in height

I want to know how these camera pedestals work, see example here: http://www.vinten.com/product/quartz-one-pedestal Has anyone tried to build something similar? What I would like to achieve, is simply a tripod system where the camera can stay level at the height I choose, and it should be easy to change the height without loking the center column. Is this a very hard thing to do?

   I have one of those hairdressing chairs that pump up with your foot.  I was thinking of making the chair "Haunted"... as in having some kind of mechanical machine that (When turned on...)  moves the height adjustment foot lever up and down... causing the chair (And anyone sitting on it) to go up, up, up in height.  What parts do I need to make this fun project?

I'm not quite sure what's brought me to asking y'all how tall you are, and I'm not sure why I care this much, but how tall are you? I'm 13 years old, and 6 foot tall, without shoes. I'm taller than most of my teachers, and only a few other kids are my height or taller. People literally look up to me. So, if y'all could post your heights, I'd sure like to know!

For a future instructable, I need to know; What is the size of Hotwheels track. ie the inside wideh and the height of the side walls? Any help appreciated.

I would like to fix this lamp in my ceiling. when you touch the switch it lights on the lamp and when you rotate your finger on the switch it changes colors and when you keep pressing for a while it changes colors automatically . can the switch be modified so that i i can have all these features working at a reasonable height normally the height for a switch in a room.or why not a remote control?
