Kit Complexity: 2
(1=Easy, 5=Difficult) Is the kit easy, moderate, or challenging to build for its most likely target audience? Kits clearly aimed at children would, for example, be rated differently from microcontroller kits.

Laser Voice Transmitter and Receiver

Reviewed: November 8th, 2011
This amazing demo shows how you can transmit sound over a laser beam. The transmitter modulates power to a laser pointer with audio from a headphone jack. The receiver is just an earphone and a solar cell; no power source. I assembled both in minutes, and it was strange (in a good way) to hear music […]
Energy Wiz
Aimed at kids 8 and up, this kit has real heart. Its 48-page workbook and components (solar cell, buzzer, two motors, LED, capacitor, copper rivets, pinwheel, etc.) take you through lessons and fun experiments that teach the basics: What is energy, as distinct from force? What forms does it take? How can it be converted […]
Fire Pit Kit
Blacksmith/sculptor Jon Sarriugarte of Form & Reform makes magical propane-powered fire pits.

Any container that’ll hold water can be the hot tub (metal stock tanks are a great choice). The stove is connected to the tub by two […]
YurtDome Kits
I’ve thought of building a dome for years, and when I was looking for a quick and relatively inexpensive place to put my workshop for the winter, this kit from Shelter Systems seemed like just the ticket. Based in Santa Cruz, Calif., Shelter Systems is still using the same non-puncturing “grip clip” technology they used […]

Its default program includes several different clock modes, but it can also display the date and temperature, or any message. Check out all the different clock faces, including Pong and Pac-Man.
Solder: Time
Solder: Time was a perfect father-daughter project: my 8-year-old assembled the components and I soldered. Afterwards, she had a chunky blue wristwatch that her cousin admired longingly, so we made another one for her. Now their friends are asking for them. I think we’ve started a trend!

Starting with the basic sock-style, this kit empowers kids to create handsome puppets and teaches different construction methods. With simple instructions, pre-marked patterns, pre-sewn parts to stuff, and packaging that becomes a stage, this kit is only two hours from coming to life. The hardest part is waiting for the glue to dry, but that’s the […]
