Scribbling Machines Some of the many uses of strawberry baskets: structural support for scribbling machines! An offset weight on a motor, a power source, a supporting structure, and a writing implement: the prototypical scribbling machine. Troubleshooting a top-heavy contraption. A clever switch to turn the contraption on and off! Typically, we arrange participants around a communal table to encourage sharing of ideas. Facilitation is crucial: both with Tinkering Studio staff, and between parents and children.
LED Throwies LED throwies consist of only a few inexpensive parts and can be made for ~$1.00 per Throwie. You can reference the parts list below or download the attached spreadsheet for more info on parts, part's numbers, vendors and application notes. Part: 10mm Diffused LED Vendor: HB Electronic Components Average cost: $0.20 avg per LED Notes: Cost reductions for larger quantities. Comes in red, blue, amber, white in both diffused and clear. Diffused works better than water clear for the Throwie application.
Soda Bottle Rocket LED Fireworks Originating in China, fireworks have been around since before the 16th Century and have been making people look to the night sky with delight. Firework formulas are closely guarded secrets handed down from generation to generation and the overall concept has not changed much over the centuries. Mix chemicals compounds, place them in a delivery device, light a fuse, and watch the fun. Circuit Boards The first success is often figuring out how to make a simple lightbulb turn on. A simple circuit: a power source, a switch, and a lightbulb. Adding a switch can be a frustrating challenge but very satisfying when accomplished. From there, the path is open to a wide range of exploration.
TRS Drawbot Once you get the hang of using TRS Drawbot, experiment with the different effects you can create by changing pens, substituting in other marking tools like pencils or crayons, working on different types of paper, adjusting the hardware, and tweaking the WAVE synthesizer parameters. Pens that "bleed" into the paper can create interesting effects at slower drawing speeds. For instance, dramatically increasing the endpoint "dwell" time in the WAVE Synthesizer code to a second or longer causes an interesting "connect-the-dots" effect with a felt-tip marker. Likewise, the amount of sliding friction under the forearm will affect line quality. If the forearm does not make contact with the page surface at all, and is resting only lightly on the pen tip, the pen's movements will be faster but less stable; sometimes a "shaking" phenomenon occurs that creates an interesting sketch-like effect.
Building a Simple Arduino Robot Step #1: Making the Chassis Place the battery pack face down and orient it so that its cable is facing you.Take two pieces of double sided tape and adhere them on the long sides of each servo. Ensure servo alignment at the bottom. Peel the backing off the tape and firmly press the servos onto the battery pack. Marble Machines Multiple paths are possible and encouraged! Catching marbles at precise points in the path becomes a great challenge Getting a marble out of a stuck position might require a little ingenuity… Discussing possible solutions and approach is part of the collaborative nature of tinkering Using a spring as a track for the marble Visitors building Marble Machines in our dedicated space at the Exploratorium

Bubble Machine Making your own bubble machine is a really easy and fun project. It can be made from almost anything, glued and screwed together with an end result which will keep kids (and adults!) amused for hours. With basic electronics of just a fan and a motor, a bubble machine is also a really easy first electronics project. This one I threw together with spare minutes here and there across the period of a week. The longest part was waiting for the centrifugal fan to arrive from Amazon, the best part was making a lot of mess in the Instructables office before realising that the shower would be a better place to blow bubbles while testing.
Wind Tubes Strawberry baskets, craft sticks, ping pong balls, pieces of foam, all transform into aerial performers once they enter the tube. Theories and intuitions about how an object would respond are challenged, and soon enough participants start making modifications to their designs to meet their own goals: some try to make an object that will shoot as high as possible, others try to get something to hover at a fixed height for as long as possible. It’s a playful and inventive approach to learning about the effects of moving air

Paper Circuits A more intricate project: a light-up model of the Bay Bridge Another more complex project: a folded origami swan with LED eyes LED lights make this fastball really fly! At the touch of a switch the girl blushes through the paper A classic interpretation of a birthday cake spiced up with some LEDs PROJECTS Sew Electric Sew Electric is a book of hands-on LilyPad Arduino tutorials that bring together craft, electronics, and programming. The book walks you through the process of designing and making a series of quirky customizable projects including a sparkling bracelet, a glow in the dark bookmark, a fabric piano, and a monster that sings when you hold […] Circuit Stickers Circuit stickers are a new medium for making electronics. These thin, lightweight, flexible and sticky circuit boards allow us to craft electronic interactivity onto new spaces and interfaces such as books, clothing, walls, and even our bodies.
Jonathan M Projects / Briefcase Boombox I wanted to make a personal soundsystem to be able to walk around with. I decided the briefcase was the perfect starting point for a boombox project. I began designing the briefcase boombox by making rough sketches on the back of a scrap piece of wood. I began by gutting the briefcase to allow for more usable space. Next I made a paneling system to line the inside of the briefcase with quarter inch aspen. I made the aspen lining in such a way that it all snapped together without screws or other fasteners.
