HOW TO - time lapse video with a graphing calculator
Instructables user yonderknight writes:
I've always wanted to make time lapse videos, but I don't have a camera with an intervalometer feature built in. In fact, I don't think very many cameras come with such a feature (especially not SLR cameras). So what do you want to do if you want to make time-lapse videos? You can buy a commercial intervalometer (yeah, right). You can check out some instructables and make one yourself out of electronic components, but what if you don't have the time/skills necessary to build one? You just want something quick and cheap. Well, you can actually use a common TI graphing calculator (I don't know of any high school student without one of these) and hook it up to any camera with a remote shutter release socket. It's quite easy, and depending on your camera can require no electronic work at all.

Homemade capacitor (Leyden jar)
Here's a 2 liter plastic soda bottle leyden jar, can be shocking, even dangerous, don't do this unless you know what you're doing (here's what they're all about, Wikipedia)...
The Leyden jar is an early device for storing electric charge invented in 1745 by Pieter van Musschenbroek (1700-1748). It was the first capacitor. Leyden jars were used to conduct many early experiments in electricity.Homemade capacitor (Leyden jar) - Link.A typical design consists of a top electrode electrically connected by some means (usually a chain) to a metal foil coating part of the inner surface of a glass jar. A conducting foil is wrapped around the outside of the jar, matching the internal coated area. The jar is charged by an electrostatic generator connected to the inner electrode while the outer plate is grounded. The inner and outer surfaces of the jar store equal but opposite charges.

HOW TO - Use a Parallax Basic Stamp II to ring a doorbell remotely
Jdege writes -
The problem? A dog that gets way too excited when the doorbell rings.HOW TO - Use a Parallax Basic Stamp II to ring a doorbell remotely - Link.The solution? Ring the doorbell at random times when no one is there, and nobody answers it, so as to counter-condition the dog - to break the association that a ringing doorbell equals excitement.
The technology? A Parallax 418 MHz RF Keychain Transmitter, Receiver, and a Basic Stamp 2.

Technojunk salvage tips
Here are some useful tips on salvaging components from old electronics. I especially like the idea of using the bottoms of water bottles to create clear, stackable parts bins.

Making flexible circuits with an inkjet printer
Here's a how-to on using an inkjet printer to assist in the creation of flexible conductive circuits. The printer is only used to transfer the circuit image onto the conductive fabric. You still have to paint the resist on by hand.

Roll your own back issue boxes
This one made me smile. Back in the late '70s, a friend of mine, a machinist, gave me a sheet metal version of a back issue box template as a gift, the same basic one used here. I went nuts, cutting and folding dozens (and dozens) of boxes for my large magazine, small press, and zine collection. These handmade boxes still grace my shelves, and like this Instructable author, I get a special charge out of the boxes I made myself over the commercial ones. Sometimes, simple projects stick with you, have an impact far greater than your expectations and time invested. This box template represents one such memory for me.

DIY TO-92 heatsink
All out of TO-220's? Thinking maybe you can eke enough performance out of a smaller transistor?
Want to squeeze a bit more current through those inexpensive TO-92 package transistors? Then add a small metal heatsink. I made this for a PWM DC motor driver, as some 2N2222 bi-polar transistors were handy.Of course, we should only operate components within their factory spec, but it's good to know this type of desperation has been previously explored - just in case. -Link

HOW TO - Make a soft-circuit LED bracelet
REACTIVEFashion shows you how to make a soft-circuit LED bracelet -
Do you like crafting or sewing? Do you love LEDs? Well, why not combine your passions with this 'wire-free' LED bracelet!HOW TO - Make a soft-circuit LED bracelet - Link.Here's a quick and relatively easy soft-circuit project we led a workshop on in April 2007. Have a little fun with conductive thread and 'sewing' circuits and make a cool battery-powered LED cuff to wear out and about. It is only powered while you are wearing it because the fastener acts as a switch. No soldering/wiring required!

HOW TO - Make a binary marble clock
Mats writes -
This is a simple clock that shows the time (hours/minutes) in binary using leds hidden beneath glass marbles.HOW TO - Make a binary marble clock - Link.For an average person it looks just like a bunch of lights, but you will be able to tell the time by just a quick glance at this clock. It might take you a couple of days to get up to speed on the esoteric art of fast binary counting, but you'll be able to tell the time right away, just a bit slower in the beginning.

Electronic graffiti artists win laser cutter contest
The fine folks at Graffiti Research Labs have won the Instrucatbles Laser Cutter Contest. I was honored to be one of the judges in the contest. It was an amazing group of finalists, with both impressive projects and equally impressive Instructables. The winning project was a low-budget camera special F/X rig GRL used in a rap video to recreate the "bullet time" effect from The Matrix.
"This will be the cornerstone of our new lab space," said GRL member fi5e. "A whole crew of creative people are really excited to put this thing to use! Thanks for helping us bring the VersaLaser to Brooklyn."

The Looty eye-gazing box
Here's an intriguing device on Instructables- The Looty was created by artist Jim Woodring to allow the users left eye to stare directly at the right and vice-versa.
Jim made and sold these devices for a time, but eventually discontinued the item. In an interview over at Hour.ca he spoke regarding the projects demise -
"It's a bad invention... I made a few to sell and then stopped because the effect is unnatural and probably harmful."
All the same, it's an interesting example of invention for self-exploration. If you do decide to build the Looty, do be mindful of any possible strain on the eyeballs - they're hard to replace!

Knit a Steve Zissou hat
Von Klaus wrote up an instructable on how to achieve this unique look -
I am a huge Wes Anderson fan, and his movie The Life Aquatic: with Steve Zissou is one of my favorites. The first time I watched it, I yearned (get it yearned) to have a hat like his (for Jacques Cousteau buffs, I know it was his hat first). To tell you the truth, the only reason why I wanted to learn how to knit was to make a Zissou hat. And yes, I am a boy which doesn't mean that I am girly for whatever. Knitting is for everybody!!!
Darn right knitting is for everyone - break that stereotype!

Start a fire with air
Here is a great little project to try out, it's called a fire-piston. It certainly isn't as easy as a piece of flint, matches or a lighter, but none of them are nearly as impressive. This will be high on my list of things to MAKE.
The principle of increasing temperature by method of compressing air is explained by the adiabatic process in which the internal energy of a gas must increase when a mass of air is rapidly compressed or the volume of a mass of air is rapidly decreased. The resulting increase in internal energy results in a temperature rise sufficient to light an ember, just like the pressure produced by an ice skater's blade is sufficient to increase the internal energy of the ice which turns ice under the blade into water.Make your own fire-piston - Link
