Make: Kit Reviews

This kit is amazingly cool and easy to use. POV (persistence of vision) displays show words or patterns that seem to float in mid-air; if you’ve ever seen one, you know what a great effect it is. A line of LEDs flashes the Y component of what you’re displaying, and you provide the X by […]

The Phlatformer is a hobby vacuum- forming machine that quick-melts 10″ square plastic sheets into form-hugging shapes. Originally built for R/C modelers to make identical, lightweight body parts, it has many uses; for example, I plan to form custom holders to display my raygun collection. The kit’s parts and thoughtful extras never skimp on quality, […]

People my age remember red plastic toy rockets from childhood that you filled with water, pumped with air, and watched as they leaped dozens of feet into the air. Well, things have gotten far more serious in the world of water-powered model rocketry, and hobbyists are reaching heights upwards of 800′ using plastic soda bottles, thin […]

This kit gets top marks for ease of assembly and low price, and because it’s preprogrammed to do all the heavy lifting, all you need to do is solder it together and attach it to the device of your choice. It’ll take an average-skilled solderer 1½ hours to assemble, and from there the possibilities are […]

Open the cool aluminum briefcase and remove your weapon of choice. Charge the pistol grip with a 16-gram CO2 cartridge. Fill the lower shaker chamber with gin, maraschino liqueur, lemon juice, Creme de Violette, and ice. Thread the shaker top and valve onto the lower chamber. Inject CO2 into the shaker. Shake. Settle. Open. Pour. […]

I was reading Boing Boing one day and saw a link to this bicycle motor kit, consisting of a 66cc two-cycle engine, drive mechanism, gas tank, muffler, and controls. The ad brought back kid-time memories for me, as I had dreamed of one day owning a Whizzer, the classic motorized bicycle. It was the only vehicle you could […]

Indie makers RLT Industries of New Braunfels, Texas, sells this lovely wooden model kit of the classic “south-pointing chariot” mechanism. Set the chariot down with the vane pointing in an arbitrary direction — south, north, whatever — and a geared differential connected to the wheels will keep it pointing the same direction regardless of which […]

MAKE contributor John Iovine has been designing and improving affordable Geiger counters for decades. After Japan’s nuclear crisis last spring, his company was swamped with orders. Now they’re working on even better designs and DIY kits. This analog counter detects beta radiation above 36 kilo-electron volts (keV) and gamma above 7keV, signaling each radioactive particle detected with an […]

Nixie tubes, beautiful relics of early computing, display their numerals with a quivery orange glow. Peter J. Jensen makes Nixie tube clock kits, and it was a joy to put one of them together, thanks to the clear step-by-step instructions and parts envelopes labeled with corresponding numbers. Jensen designed the clock and circuit board himself, […]

Alternative time-telling devices are compelling, but only if they’re easy to read. Building a kit can be satisfying, but only if it leaves room for creativity. The Chronulator clock kit fits the bill on both counts. Solder it together, and you’ve got a microcontroller-based clock that converts time to current, displaying hours and minutes on […]
