Hex Nut LED Flashlight. To attach the switch to the nut I used super glue to glue it in. If you do this, be careful that you don't get any glue on the button itself, or you won't be able to press it in anymore. Then I attached a wire to one lead of the switch, which would go to the positive battery terminal. To make sure that the switch stays, in place, I jammed in a small piece of cork (wood or plastic would work just as well). Duct Tape Speakers. A Vertical Wind Generator from Washing Machine Motor.
Phone Mount on Plane Seat. DIY BioPrinter. We started out by messing around with an old inkjet printer that we literally saved from a sidewalk somewhere. There's already plenty of interesting things you can do with an low-end off-the-shelf inkjet printer, but they do have some limitations, which we'll get into in the next Step (or skip straight to Step 3 for how we built our own bioprinter from scratch, that you can see in the first picture above). Undressing the Printer We disassembled an abandoned HP 5150 inkjet printer for use as a bioprinter. Just rip off all the plastic covers you can find, but make sure you can still operate the reset buttons etc. on the front panel.
There's a little momentary switch that senses whether the cover is open. There's also a momentary switch inside the paper handling mechanism that senses whether paper has been loaded. Once you've got your printer all undressed, and figured out how to activate the cover-closed switch - print something! Cartridges Prep Filling the Cartridges. Geo Data Logger: Arduino+GPS+SD+Accelerometer to log, time-stamp, and geo-tag sensor data. UPDATES Oct 17, 2013: I have published a guide on using your Android phone to accomplish a similar task by leveraging your Android device's built in GPS and sensors. Feb 6, 2013: Featured on GeoAwesomeness Nov 24, 2012: Featured on Hackaday Nov 21, 2012: Featured by John Boxall @ Freetronics Nov 20, 2012: Featured on Dangerous Prototypes INTRODUCTION I thought it would be educational to build a prototype that I can take on the road to log, geo-tag, and time-stamp sensor data to be analyzed later with mapping and/or data analysis applications.
So I figured why not start with a gadget that can log road conditions. This prototype, the Bump-O-Meter, measures road conditions by using an Arduino, a GPS receiver, an SD card, and an accelerometer sensor. This guide is divided into the following sections: Arduino IDE 1.02 MiniGPS 1.4: This is a nifty utility to configure the LS20031 GPS receiver. 8 Hour Mini Recycled Survival Candles in 10 steps! 8 Hour Mini Recycled Survival Candles This Instructable will show you how to make 8 hour survival candles out of everyday items.

Most cameras these days have an automatic white balance setting to control this issue, but everyonce in a while it can be inaccurate. Color shifts are caused by different color temperatures in light, we call these "Kelvin temperatures. " Daylight has a Kelvin temperature of 5000, and is the most neutral you can get your photo to look. Have you ever photographed something in your house under a typical house bulb and the whole photo turned out orange or yellow?
That's because typical household lights have a Kelvin temperature of about 3000, which can look yellow, but because the human brain is so sophistocated, it corrects this to daylight temperature for us. Tungsten and flourescent light bulbs can also have a similar effect, where we don't see the shift, but our cameras do. Tungsten bulbs tend to have a magenta shift to them, while fourescent bulbs can turn a photograph green. Bentwood Rings. This is my first Instructable, so I hope that I do not forget anything. I was commissioned by a close friend to make a set of rings for a surprise engagement and a set for wedding bands. I started off with solid wood blanks and a drill press. After making what I thought be a perfect ring, it broke after a couple weeks of wear. At this point I went back to the drawing board and started to research bentwood rings. This not only solved the issue of strength, but also allowed for the beautiful wood grain to show.
So here are the steps I used to make a set of wedding rings. 1. 2:Making the Ring: Cutting: Start of by selecting the veneer. Origami Crystal Sculpture. 5 minute fish eye mount for compact cameras. How to Make 'Moss Graffiti' Kee Klamp Shelving. My original idea was to simply copy the shelves I'd seen, so I started looking for scaffolding poles and a way to cut them. This lead me to Kee Klamp ( an awesome system of poles and clamps - or Klamps :) - that you can literally build anything with as long as you have an Allen Key. The original design I'd seen had each shelf supporting the next by using the flange bases ( The only problem with this was that I'd need to do a lot of pole cutting and the height between the shelves would be forever fixed.
If I changed the design so that the poles were at the edges of the shelves rather then between them, I could keep the poles as one long length and use the side mounting clamps ( at whatever height the shelves needed to be. DIY Battery: Power an LED Flashlight with Pocket Change! We must prepare the barriers which will sit between the nickels and pennies in our pile. With a sharp knife, like an X-Acto knife, carefully cut some thin cardboard or similar material to the size of a penny. How many wafers you must prepare depends on how many coins you end up needing. This amount may vary due to a number of factors.
If you end up needing too few to make your battery long enough for the flashlight, simply stack nickels without barriers on the end to fill the space. I chose the backing of an old notepad for my material. If you're young, clumsy, or for any other reason think you might have problems then please do this with supervision or ask for help. FREE EMERGENCY ELECTRICITY!! DIY Batteries with This Penny Power Hack. Brake drum blacksmith forge. This is the basic design. A 2" floor flange was bolted to the underside of the brake drum to which a 2" coupler was used to attach it to a 2" T-connector. A longer coupler was attached to the side to accept the hair dryer and a bottom pipe was attached to the bottom to collect the ash. This is usually capped with a 2" cap so the air can't escape that direction but I didn't want to have to wait until the forge cooled to unscrew the cap and empty the ash and I was concerned the cap would become permanently attached by rust since the forge would be stored outside in the rain.
I'll show you how we handled that part. Note: The brake drum was free but it took visits to several garages to find it because brake drums are harder to find now that disc brakes are becoming more common on the rear wheels of new cars. Filing Cabinet Smoker. Make a working lock and key. Firstly, I'm going to run through the basics you need to keep in mind when preparing a model for 3D printing. If you have already used 3D printers, then feel free to skip on to the next page, or take a quick look at the bold writing to double check the basic rules.
There are several types of 3D printer available, and depending on what one you're using will affect the way you make your model. For example, a printer using photopolymerization uses light to harden a liquid resin in layers, so when completed the model is simply pulled from the liquid, allowing for all types of undercuts/ interlinking items. However, Thermal Extrusion printers heat plastic and print each layer on top of the previous, meaning that it has to create supports to reach any undercuts in the model. As a result, the supports need to be cleared away before the part is ready, so interior or interlinking details are not really viable. So, for thermal extrusion here is what you need to keep in mind. 1. 2. 3. 4. Phew. USB Freeform Arduino. All the parts are about the same as used in it predecessor, "Freeform Arduino" except that I used film canister instead of the antistatic tube, with an addition USB type A connector. Schematic shown below is comprised of the minimum components and could be used FTDI cable to upload the sketch.
On the actual USB Freeform Arduino did not included the 1K resistor and 3mm LED that connected to pin D13 as in the schematic. Parts These are the minimum components to get Arduino up and running.

Combination Lock USB Memory Stick. Smelt Your Own Ring. Nickel Ring / Pendant. Handmade buffalo nickel ring. Create your own ring using nothing more than a buffalo nickel, a hammer, and a lot of patience and time!
Buffalo nickels are nice because they seem to be a little more malleable than the usual nickels you find nowadays. The basic premise of the project is to hammer along the sides of the coin until they flatten out. This instructable adds a variant where you add another coin on the outside so that it can swivel around the main one. This instructable doesn't have the best pictures, but at least it'll get you goin with the knowledge that it *can* be done! Things you'll need: 1) A buffalo nickel 2) A Dremel tool (optional but nice to have) 3) A glove (sometimes drilling the coins can make them really hot) 4) A lot of time (anywhere from 10-20 hours, depending on how much effort you put into it) 5) A hammer. DIY Clawfoot Bathtub Couch. Let me start by saying that this idea is not new. First shown in 1961 in Holly Golightly's apartment in the film "Breakfast at Tiffany's", it was then re-created by Jared and Jill Morrison of Ruff House Art for Phillip Morris of all folks a few years ago.
This was followed by a New York Times article covering the concept of a claw foot bath tub couch (when I first got turned on to the idea) which then prompted several bespoke retailers to try and recreate the work. There is currently a reproduced DIY version on a french blog, however it provides zero instruction, and takes a slightly different design approach by using an elevated seat. There's also a retailer on Etsy called Redux Tubs out of Canada who is selling the couch from $1,100 and up.
Finally, my co-worker Carley has also wanted to build a bathtub couch for some time. History accurate as of publish date September, 2012. Slow smoker. Home made cold smoker. Sand Fire Garden. 55 Gallon Top Bar Barrel Bee Hive. High Powered LED Solar Lighting System. While I love making proof of concept solar projects, or solar projects that I might use if the world comes to an end, I prefer to make solar projects that are useful in my day to day life. (I love my solar FM radio, but I've never had the need to use it in an emergency situation) This past summer my father has been complaining about installing a lighting system for the back of his yard.
The big issue being that he hates running wire 100 yards just to get three lights to turn on at night. Plus, being the over achiever that he is, he decided to bury the wires so that he wouldn't run over them with the lawn mower. I decided to make a high powered solar lighting system so no wires would ever need to be run to the back of the yard.
Oh, and I'm not talking about a few little wussy LEDs inside of a jar, I'm talking some high powered 3 watt LEDs inside real metal lighting enclosures. (If you like my project, vote for it in the Off The Grid Contest here at instructables, I'm the first entry. The "Reverse Joule Thief" Battery Charger. A look at the circuit will tell you this is not a run of the mill JT configuration. Most obvious will be the fact that there is only a single coil involved (the 220uH) - we are using a second transistor (Q2) and C1 to take over the timing requirements. This allows us to use a wider range of coil values, as well as operate over a larger voltage range. Besides reversing the charge / discharge order, this circuit also reverses the location of the driver transistor and the coil, but wait, that's not all!
The transistors all have reversed polarities, and even the output voltage is reversed! No, it isn't an error! Diode D1, the LEDs and the charged battery all have their polarities reversed! That's because this Joule Thief is configured as a voltage inverter. To improve efficiency, the traditional JT relies on a fairly constant battery supply (over a millisecond or so) to give it a boost when it is delivering power.
