The holidays are here again, and with them all the usual trappings: joy, good cheer, and the crippling fear that someone might be harboring explosives in his or her nether regions. But don’t let the TSA bogart all the intrusive holiday fun; you can build your own handheld microwave body scanner at home, ensuring the safety of your holiday guests. All you need is a feedhorn for a satellite dish, an optical mouse, and a handful of other low-cost parts.
1. Buy a mount for a Garmin nüvi GPS unit and a hard case for your phone. (There are cheap versions of both on eBay.)
2. Carefully cut away the clip ends on the mount's attachment bracket. This allows you to stick the bracket flush to the back of your phone's hard case.
3. Affix sticky pads to the bracket. Align the bracket on the back of the hard case and attach it firmly.
You remember the Chumby--it's that cute little Wi-Fi device designed to constantly stream a greatest-hits lineup of your favorite Web apps to places where your laptop, netbook, or smartphone can’t go. The Chumby on its own makes for a cute alarm clock, but this DIY upgrade for the tiny media display is really going places. (Ha!)
I love Maker Faire. I've had a blast with makers and their wild creations in San Francisco and in Austin, but this past weekend, Make's traveling DIY circus came right to my backyard here in NYC. It's a circus that happens to include a pulse-jet-powered merry-go-round, seen here, among other delights. Which is the right kind of circus.
Every now and then a DIY project surfaces on the Internet that’s so cool we have to share it, especially those we should probably recommend you not try at home. YouTube user Larsplatoon’s 1.25 kilojoule coilgun is exactly this kind of project. We’re not even sure where this battery-powered projectile slinger falls with respect to your state’s gun laws, but perhaps the best advice we can offer is what’s plastered to the side of the coilgun’s receiver: “Danger. High Voltage.
A few years ago, R. Bruce McDonald figured it was time to do something unique with his 1966 Cub Cadet. The obvious solution was of course to remove the stock 12 HP Kohler engine and replace it with a Garrett GTP 30-67 gas turbine.
Our collegiate scholars hold our future in their hands, so it’s always good to see them apply themselves to projects like WiDrive, a remote-controlled, camera-mounted car that can be driven in the first person using an iPhone and a pair of VR glasses.
Tired of waking up in the morning only to find yourself in the same lame place you woke up in yesterday (and the day before that)? Winscape is a DIY project for you: install two HD plasmas in faux window frames that display whatever scene you’d rather see out your window. Using a Wiimote, the setup even detects your position in the room and shifts the perspective screens' high-resolution video to create the illusion of looking out a real window.
Since we launched our archive viewer last week, it's been a thrill to read emails with everyone's kind words and impressions. Particularly great was reader Michael Dixon's story involving salvaged scrap wood from ships arriving at the Port of Houston, a suburban backyard and the October 1969 issue of Popular Science.
