arrow back stop

Anybody have any ideas about inexpensive fabrics that might stop arrows? i have seen arrow back stop netting online but it is prohibitively expensive. i am a back yard archer living in a city and i think my neighbors would feel safer in their yards if they thought my net might stop an arrow.

do it yourself 4 wheel adult sized pedal bike car

In spring I got idea to build a 4 wheel pedal car for my son. To use wheels from old bicycles, to make it as small and light and simple as possible and to make it possible to fit even an adult person. I was really disapointed surfing internet, as I found almost no free ideas, plans or experiences how to do it. It is no nuclear science, people would invest millions in their know-how, so they would need to hide it! Now it's autumn now and our car is done. I decided to share my experiences and detailed photos as free plans with other people, interested in self buliding pedal car of that kind. I wanted my 9 years old son to learn basics of construction and working with metal and wood. He did almost all hand works by himself and he is very proud on it. It is a very good way to move your child from TV and computer games! It is all on our 4 wheel pedal bike car web site

suggestions for retrofitting a late1970's portble cassette player/radio

Hi, I was given a late1970's portble cassette player/radio. the electronics are dead. but the body is in very good condition. It would be cool to retrofit it as a portable amp to connect to my phone or mp3 player I want to disembowel the machine and then fill it with an amp and lithium ion battery pack. it's a bit larger than a 6 pack of beer can any point me in the direction of some instructables or sites with some info?

123D Design tutorial for technical parts with accurate dimensions?

I'm an engineer with ~7 years of experience using Solidworks (professional CAD software). After hearing about Autodesk 123D Design here on Instructables, I tried to start using it to design and print things with my home 3D printer. However, I'm initially finding it very frustrating to use (more detail on that in a minute) - and I'm not sure if this is just because I'm stuck in my ways with the software I'm used to, or if I'm just trying to use 123D for something it wasn't really intended for. To try and give some concrete examples - I understand that you can create 3D shape primitives (rectangular prisms, cylinders etc) and assign them dimensions when you create them. I also understand that you can create 2D sketch objects and define their dimensions. What I don't find intuitive at all is how you can assign the dimensions of objects relative to each other. For example, say I want to make a 10x10x1mm bracket, with two 2mm diameter circular holes that have their positions on the face defined by the distance from their centers to the edge of the bracket. In a parametric CAD program, that is very easy to do in a 2D sketch and then extrude to a 3D solid. In 123D, I understand that I can create a rectangle primitive and then put holes in it using cylinder primitives - but it seems impossible to define the exact location of those cylinders relative to the edges of the rectangle; also impossible to create a sketch with two circles in it and a dimension defining the distance between their centers. To give another concrete example: at the 4:20 mark in this video (from this Instructable), he draws a circle on top of an existing rectangular part, and then "centers" it by just dragging it around freehand and eyeballing it. Would it be possible to define the center of that circle relative to an edge, corner, or center of that existing rectangle? Or can 123D just not do that? What I'd like to see, if anyone is up for it, is a step-by-step tutorial (preferably in video format) for making some sort of "technical" part where the dimensions matter and it isn't sufficient to just eyeball it and drag things around. e.g. a bracket like this (exact dimensions don't have to be what I drew here, but you get the idea). All of the tutorials I've seen so far - including the official Autodesk ones - seem to just focus on eyeballing it/free-handing dragging parts around.

Batteries Are Expensive, Who is using both Solar and hydro/ wind turbines at same time?

Hello, Let us use "Solar, Wind, and Hydro" all at same time. I am working on development projects in Togo, West Africa, I have a room there by the year in two locations. The solar panels are cheap enough, but for the cost of one good size battery I could build a wind or hydro generator. I do not see many setups where solar during the day, coupled with water and / or wind at night. Obviously harnessing the water from a river is the most stable. If seems sort of short sighted to only use solar, why not do all three, Solar, Wind, and Hydro at the same time, and slow the need to store electricity, because in my opinion, the batteries are the problem, the big problem.

Is the Makerspace Contest Effecting 'Ible Featured Times?

I was just curious if the Makerspace contest is effecting the time it takes to get your 'ible featured? And if so, by how many days? For example, my last featured 'ible wasn't featured for a few days after posting (and I didn't post it over a weekend or holiday or anything). Usually, the featuring (if it happens) happens much sooner. But I was just thinking maybe the Makerspace contest is effecting the times because there are so many more instructables getting published right now (some of the prizes in the contest are for highest number of instructables published and highest number of featured 'ibles).  Your thoughts? Has anyone else experienced this, too? Thanks!

quick release tripod plates

So for a few years now i've been using a small speaker setup strapped onto the tail of a longboard skateboard to provide music at skate meets and fun bike rides etc, and it's worked well enough, however at 13kg on the highest point of the board it has a tendancy to flop into corners and mess with the handling. Recently the amplifier broke so i want to use this opportunity to redesign the whole setup... for a start im hoping to reduce the weight by about 5kg i found this video (https://www.youtube.com/watch?v=QAI5W6AgSYg) on youtube of a skateboard sidecar for a child which i intend to modify for the speakers but i don't want it permanently attached to my board, would 1 or 2 quick release tripod plates have the strength to keep the mechanism attached to the board until i wished to remove it? i know you can get plates to support some particularly heavy cameras so would there be one that would be up to my task?

Giant Slip 'n' Slide?

Hey Guys     I'm graduating high school in two weeks and my friend and I were talking about something to do the day after finals. I brought up doing a Slip n Slide down a nearby sledding hill. I found a site that has some basic information on the hill. It's 200-300 feet long and has a 60 degree slope. Yeah pretty steep haha. So here's what I need to know: What is a good material for this slide that will hold together but is still relatively cheap? Tarps were the original idea but I was told menards may have large rolls of plastic you can roll down a hill. What is the best combination to get the slide slippery? We dont have access to water so we'll be bringing just enough in garbage cans to wet it down. So what kind of soap or lubricant is best for the slide? It would help if it didn't burn afterwards! Thanks for the help in advance. Picture of the hill in winter  3.bp.blogspot.com/_ymkfNB3shbw/R1sBuKwdScI/AAAAAAAAAUU/JD8auciBxMM/s400/sled22.jpg

Fuel economy of the world's longest in-service ship

The Emma Maersk is the second longest ship in the world, and the longest currently in service. It's so large, it looks photoshopped into any picture it appears. Driving such a large ship requires a lot of power. From Wikipedia:The Emma Maersk is powered by a Wartsila-Sulzer 14RTFLEX96-C engine, currently the world's largest single diesel unit, weighing 2,300 tons and capable of 109,000 horsepower (82 MW). The ship has several features to protect the environment. This includes recycling the exhaust, mixed with fresh air, back into the engine for reuse. This not only increases efficiency by as much as 12% but also reduces engine emissions. Instead of biocides, used by much of the industry to keep barnacles off of the hull, a special silicone-based paint is used. This increases the ship's efficiency by reducing drag while also protecting the ocean from biocides that may leak. The silicone paint covering the part of the hull below the waterline is credited for lowering the water drag enough to save 1200 tons of fuel per year.We started talking about energy consumption after watching a practice version of Saul's upcoming E-Tech Keynote, Energy Literacy, and Dave Culp of Kiteship and Speed Sailing did a back-of-the-envelope MPG calculation for this ship:A few more facts about Emma Maersk:Running at her rated 80 Mw, her main engines burn 14 tons of residual fuel each hour. Annually, that's 97,400 tons of fuel. Her auxiliaries, delivering their full 30 Mw, burn an additional 6.6 tons/hour, for a total fuel burn of 20.6 tons/hour. Given 290 steaming days/year (80% capacity factor, which is conservative), this yields a total annual usage of 143,400 tons or about $64.5 million in annual fuel costs.Burning 20.6 tons/hour = 6724 gals/hour. At 31 kts/hour, this equals .0046 nautical miles/gallon. At 6076 ft/nautical mile, that's 28 feet/gallon of fuel burned.The 1200 tons saved by her "revolutionary" bottom paint represents a bit less than 1% of this cost, so increases her fuel mileage to 28.2 feet/gallon.Dave concludes:You gotta haul a lot of containers full of $7 tee shirts to make this profitable.28 feet/gallon!Images from jtashipphoto.dk and Wikipedia.

I need an idea of what could be made from two curved glass deli cabinet doors.

Along with a few flat glass shelves, I was given two large curved glass deli cabinet doors as shown in the image below. They still have the aluminum bars attached to the long ends. One the top side that was formerly attached to a hinge mechanism and one being the lower side that formerly held a rubber seal. I only have the doors, as the rest of the cabinet was used for another purpose or recycled by the previous owners. I'm trying to come up with a project to repurpose them for, but I'm drawing a blank. They are about 4 feet long and 2 feet wide with no cracks.  They appear to be tempered glass and are very heavy. Here are some ideas: -  large vertical display cabinets made from wood with the glass doors on the front of them might work by using the short ends as the top and bottom. - large horizontal display cases made from wood with the glass doors as the top or front and access to the rear. - Some sort of greenhouse window. - I eventually would like to build a house out of shipping containers. Incorporating these into the plans as windows would be cool as long as I can figure out how to frame them out to give a good seal. perhaps as a skylight? (Of course, not being double paned, they wouldn't have much of an R-value). - Something artistic that can utilize the glass panes and be hung on a wall or used as a display. I have access to a Hackerspace in St. Louis, Missouri with plenty of tools and other raw materials. The pieces are so large that I'd have to work on the project and clean up each day rather than leave the project out. It's a shared space, so I don't want my stuff to be in the way of others. Any input from the Instructables community would be helpful.

Potentiometer/Variable resistor with AC advice

I'm a computer store tech who knows how to solder some(but DC stuff only) and who also enjoys cooking, so my ? is: What's the best choice of pot. for use with US household current to actually control the cooking temp of my hotplate? End result is to eliminate the annoying "heat spikes" you get due to lack of a pot. in the design, IE literally everything sold these days turns on at full current/temp until it reaches X temp, basically it's just temporally defined by how far you turn the knob, and your pancakes wind up crispy black around the edges and gooey in the middle  instead of golden brown and amazing all over. I want it to turn on at X current until X temp (like electric frypans/burners did if you're old enough to remember.) All I need to do ( I think) is add a pot/VR into my burner's element  "line" the right way, it already shuts off at X temp just fine. Incidentally, that's the "click" you hear when any home electric cooking device (sold in North America, at least) hits temp or turns on, the temp. control switch thingee connecting. It's NOT a VR/pot, just a pair of electrodes JUST barely touching strapped very tightly to some ceramic discs. It uses thermal expansion of the discs/electrodes to make things just a tiny bit bigger and separate the tiny little electrode spoons  But all that boring geekspeek affects in this configuration as basically just temporal heating, IE no reduction of the amount of heat in my frypan, just the cooking time. Science says if I reduce the amount of electrons flowing thru it just slightly as well,  it'll be colder but still hot and still shut off when it's hot enough. A pot/VR wired in the right way will do exactly that, won't it? After some research I'm thinking something like a 30-50K "B"-taper pot. wired with 2 of 3 traces (https://www.instructables.com/id/Wire-a-Potentiometer-as-a-Variable-Resistor/), I'm looking for a "broad" response range while turning with a tight  "pinch" effect at low end for amazing banana-brown-sugar-pinch-of-nutmeg pancakes with coffee on the tiny balcony/fire escape in the morning but I have no idea how the numbers work for AC currents. Does 120vAC mean a different pot or a diff config/approach altogether? Or should I be looking into AC variable resistors, instead? I know an awful lot about "base" science, enough to get me this far, right, but AC throws me for a loop a lot, and there's a gap in my knowledge/experience, between the basic stuff and how it applies to stuff like my application, I don't get a lot of the numbers/formulas and how to use them.  A VR would the ideal tool here, but they are hard to get in the right form with the electrical qualities I need, whereas pots are usually "turning switches", right?

RIR Sensor with ~3ft detection capability?

Question for you sensor experts... I'm looking to do a project that would involve detecting when an item passes through a doorway near ground level (~6 inches above ground level).  Doing a bit of research it looks like a reflective infrared sensor would do the trick ... only issue I have come across is that there seem to be a slew of these sensors with detection capability of about 15mm max and then another class of these (home security grade) that have detection capability for several 10's of feet. Any ideas on a RIR sensor (links appreciated!) that has capability ~2-3 feet?  Another caveat is I'd like to string up multiple of these sensors in a close proximity, each with the sensor observing a 2-3 ft area right in front of it.

DIY Steering Wheel

Hello, I'm new here. So, lately, I've been thinking about making a steering wheel for my PC, with a simple up-and-down gear box and 2 pedals for acceleration and brake. Steering Wheel. I'm using a polystyrene sheet, to cut out a wheel from it, and in the center, there's space for installing a phone holder. I'm planning to use my phone's gyroscope and simulate it to the PC. Pedals. I've figured by using foams underneath, we can place a nail and a foil separated and when we press the pedal, the foil touches the nail and circuit gets completed. I've a general idea, but I'm stuck on how to give that signal to PC as to simulate as a button (say for acceleration and brakes.) Gearbox.

Give me detailed instructions I could do it, but I'm more at home with working out how to wind the detector coil than what to do with it. The reason is this My sister has a problem, she is in danger of becoming a cat lady, or at least over run with strays or other peoples cats. Her current plan other than catching the visitors that are clearly street cats and delivering them to the local shelter, is setting a camera trap aimed at her cat flap and posting the visitor photos on the local area FB page with is this your lost cat under it.  couple of the poor conditioned strays she has managed to get to the shelter have been chipped it is  reasonable to assume that some of the others must be to, and they would be easier to catch possibly if their  owners were trying to do it. Even a simpler system that just connected chipped cat with photo, and there by identified which cats aren't chipped so presumably are true strays not just nominally owned would b of help those could then be targeted for capture and re homing first.

Mac G3 password hacking?

I got a second-hand mac G3 for Christmas, from the sysadmin at my dad's office. Unfortunately, the sysadmin neglected to remove his accounts (and passwords), so as of yet it's impossible to get past the boot screen. Does anyone have any ideas about how I may crack the password or hack into the account... (changing the root password in single user mode doesn't work...) Oh, and by the way, it's running OS X of some sort, but since we can't log in, it's hard to know what cat it is. Help please!UPDATE:With the help of this site, we made an administrator account. We still don't know the master password, and there are a few untouchable files, but we can basically do whatever we want. The next challenge is to connect it to the internet...If you want to know how we got in, here's what we did:(1) we held down command (the propeller) and S as it booted --> this opened single-user mode, a command-line interface with root priveleges(2) instead of "rm"ing (removing), like the web site suggested, we "mv"ed (moved) /var/db/.AppleSetupDone to /var/db/.AppleSetupDone.old(3) we rebooted, and followed the instructions on the screenWhat did this do? It moved the file that told the computer that the computer was set up, so the computer ran the setup "wizard" like it was the first time the computer had ever been booted. After that, all we had to do was follow the instructions on the screen to set up an administrator (root) account. We also learned that the cat is panther, so we might be updating it to a newer version.Thanks for the help!

Did you see a UFO or not?

I could not sleep so I went for a little bike ride to get some fresh air and burn unwanted kalories. To my surprise one really bright "star" began to move and because it was night my conclusion was a plane at low altitude or making a turn. After a while however it looked more like this "light" is still coming towards me and if you know planes this would mean it should have crashed already - which it did not. But it definately came closer and once almost over me I also realise it does not move in a straight line, more in a slight zick-zack movement. Biggest surprise was the shape I could make out, definately no plane that I know of! To me it looked like a cigar shape which was much wider in diameter on one end. Can't say front or back as the flight patter did not incate anything like this. Any directional changes happened without the shape changing direction, if it moved to the right than without turning - it just "slided" while the long shape kept pointing in the same direction as before. Took about 10 pics on my phone but even after checking on the computer there is only black on a black background, not even a single star visible :( Just to get me right here - I do believe in other planets out there having intelligent live but I do not think intelligent "creatures" from outer space would come to visit us. The term UFO means unidentified flying object and nothing else was there that I saw - just something that makes no sense in terms of following known laws of physics flying through the night sky. Would not even bother to write about it if any of what I saw would make sense to me. There was no sound, which was really strange. IMHO the craft was at an altitude between 1000 and 3000m not higher. It also seemed the light I thought came from a plane was coming directly from the fuselage or hull and not a lamp, looked like the outer surface was glowing. But seeing something moving quite fast over your head with no sound at all is just weird.... The zick zack movement was strange too but when the craft took off to disappear into the night it was like instand accelleration. Within an instand the light went really bright and was gone over the horizon - never seen anything move that fast! I know there are lots of secret military aircrafts out there, same for people playing with drones but this was much bigger, would say at least 400m long. Even if the altitude would have been much lower in reality than what I thought it would have been huge - and totally silent. Spent the last hour or so checking some videos on Youtube but nothing really matched what I saw. So my question(s): Did you ever see something moving with impossible speeds, making impossible turns or accelerating like no tomorrow in the sky? And if so: Did it look like an oversized cigar, bigger on one end and with a "glowing body"? Do you know of any prototype craft being the size of at least two Airbusses in lenght that can fly without making any noise at all? Disclaimer: I do realise what sort of "crap" I am writing here. I also acknowledge that I don't know everything that can fly. I do not think that I saw an UFO in terms of being "out of this world". Yes, I know my level of insanity ;) I do not claim to have seen or being abducted by aliens either ;) And no, I have neither been blind drunk nor on drugs when I saw this ;)

While they don't even show In SRWare Iron or SlimBrowser,  in Firefox the video window is visible and sets up ready to play, but when moused over it displays a meaningless error ("Curses!", "Aw fiddlesticks!", etc.) claiming "This video can't be played with your current setup". "Leg for a wooden table (incredible strength)" is a recent 'ible example. If I go through the process of searching the page source code for the video (https://player.vimeo.com/video/171982493 in the above example), copy and paste the URL, and go to the link directly, the video plays perfectly, so it's not some browser or other setting that's blocking Vimeo. (Even tried with all browser add-ons disabled - no joy.) I'm not competent enough to troubleshoot the issue, but it's frustrating to have to dissect the page to play embedded videos in a separate tab. Any work around would be appreciated. Thanks.

painting a lawn flamingo

I am trying to bring back the pink quality of several Yard flamingos.  I know I could buy new ones, but certain people would rather keep for sentimental reasons, so I am trying to restore them.  My problem is when they are painted, after a period of time it chips off, I believe it is because the paint cannot deal with the flamingo plastic swell and shrink of the heat of the day and the coolness of the night.  Any ideas to extend the paint's life, would be appreciated.

Any suggestions on non slip natural material to put on my dogs paws

I'm looking for some suggestions to help my dog who is recovering from disc surgery. I've tried all the usual boots,socks,balloons etc. It is short of a nightmare watching him tread so carefully on slippery floorboards.I'm convinced he's lost muscle mass from not being able to walk normally anymore. Short of covering all my floors in rubber mats, I know there has to be a solution. I'm after something that is non toxic that I can rub on his paws. It has to have a tacky feel..you know like those silicone dots you can buy to stop slipping. Materials like those used in surfboard wax ..I've checked out the feel of surfboard wax and it feels ok but it feels like it's lacking the tacky element. The other thought I had was to buy a mould kit and get an imprint of his paws and make a slip on foot cover in a silicone. I'm not too sure what type of silicone to use for this..would it be like a latex that would be good to grip the floorboards? Any suggestions on what materials to use? Thanks

Remove axles from jogging stroller wheels?

I have a pair of twenty inch wheels from a jogging stroller with "sealed" bearings that I would like to remove the axles from. I've loosened or removed all of the nuts including the locking nuts from both sides but the axles are still firmly seated/connected to something inside. They came from the frame/carcass of a stroller similar to this, but they are not the quick release.

Giving Credit for a Recipe

I have a recipe that I really like and on which I would like to do an instructable.  My question is about giving proper credit.  I looked around at some recipes on here and didn't see anything about giving credit.  So the recipe I want to use is a common basic one, but the one I use, I found on a blog.  So do I reference the blog in my instructable?  Is it different because I'm just teaching how to make the recipe?
