[Rob] lives in a 100-year-old house, and with these antique lath and plaster walls and old window frames comes a terrible amount of drafts. The usual way to combat this energy inefficiency is with a thermal imaging camera, a device that overlays the temperature of an object with a video image. These cameras are hideously [...]

Whether inspired by the vaults of Fallout or the mysterious wrist device worn by [Turanga Leela], we’re just glad to see someone finally made a wrist-worn cellphone, The Ultimate Wrist Watch, as the creator [Rob] calls it, is based on his Motorola Defy smart phone, tucked inside a neatly modified iPod wrist band meant to hold a [...]

The Hoboken hackerspace, MakerBar, recently hosted a very special guest – [Rob Bishop] from the Raspberry Pi Foundation. Wanting to impress [Rob], [Zach] and a few others from MakerBar put together a wearable computer based on the Raspberry Pi in just a few hours. Putting a Raspi, small Bluetooth keyboard and mouse combo, and a USB charger [...]

We discussed [Rob]‘s Tesla Gun in the past. At that time, the build looked very impressive, but had not been fired yet. Fortunately, [Rob] got the device working and brought it to Toorcamp. He took the gun out every night and demoed the handheld Tesla Coil by having volunteers catch the streamers with a knife. The [...]

[Rob] has been hard at work designing and building this LED suit which he can wear to parties. He’s got it working, although right now it’s just a pair of pants. It reacts to sound, and has the potential to be controlled from a smartphone via Bluetooth. You’ll find a video description of the build embedded [...]

[Rob Hemsley] sent in an update to an RFID-based door lock. Previously, if you wanted to enter the MIT media lab, a RFID-enabled card was required to get in. Now, with [Rob]‘s update, you only need to tap the door handle in a ‘secret’ pattern. The earlier RFID-enabled build used about $80 in hardware, not [...]

The Dark Knight Rises is out now, and [Christian] over at MakeIt Labs decided to show up everyone at this year’s Halloween party with these custom made Batarangs. After the Batarangs were plasma cut out of 11-gauge steel, [Rob] beveled the trailing edges of the wing, powder coated them, and sharpened them with a grinder and [...]

Hot off the heels of his web server for the TI MSP430, [Rob] shared a MIDI booster pack for the MSP430 LaunchPad, an exceedingly inexpensive and ever more capable microcontroller that is getting somewhat of a cult following. [Rob]‘s MIDI booster pack contains a MIDI in and out port as well as just about whatever MIDI [...]

Need a tiny web server? [Rob] over on the 43oh forums made an Ethernet booster pack for the very popular TI MSP430 microcontroller. If that’s not enough, [Rob] also put together an all-in-one solution with a MSP430 and Ethernet controller that can be powered by a battery. Along with the web server that fits in [...]

After reading The Five Fists of Science, a retelling of ‘war of the currents’ between [Tesla] and [Edison], [Rob] knew he needed a Tesla gun, the sidearm of the story’s protagonist. Since nothing as stupidly awesome and dangerous as a portable Tesla coil has ever been made, [Rob] needed to make his own. [Rob] started his build [...]

We don’t recall having heard the term ‘collimated display’ before, but we’ve seem them in action. These are mirrored projection display that give the viewer a true peripheral vision experience thanks to well-designed optics. Here is a project that [Rob] and [Wayne] have put a ton of time into. It’s their own version of a [...]

Free-form Christmas ornament Here’s [Rob]‘s free form circuit that’s a Christmas ornament for geeks. It looks great, but sadly isn’t powered through a Christmas light strand. It’s just as cool as the skeletal Arduino we saw. Prototyping with flowers Well this is interesting: protoboard that’s specifically made to make SMD soldering easier. The guys at elecfreaks [...]

Does a yo-yo work in zero-g? How about a paper airplane? These questions were answered in 1985 on the Space Shuttle Discovery, but reproduction of results is the cornerstone of the scientific method. [Rob] is about to reproduce some of the awesome zero-g pictures by riding on a vomit comet and taking a few pictures of [...]

[Rob] has been working on his drum trigger build, and he’s finally decided to share it with us. His drum heads and triggers don’t look like anything we’ve ever seen, but he’s pretty confident he has a good kit in the works. The first unconventional of the build is the drum triggers. The triggers are [...]

[McKGyver] needed a few parts manufactured. Instead of going the normal route – finding friends with machine tools or paying a machine shop, he improvised a rudimentary metal lathe. As much as we love 3D printers, they’re not the be-all, end-all solution for everything. Sometimes, you need to get a little dirty and do it [...]

Sometimes, not all our builds work out the way we hoped. That’s what happened to [Rob] and his attempt at a Delta robot that does stereo lithography. A Delta robot is capable of very fast and precise movements, so [Rob] slapped a laser module on the end of the arms. After putting some UV curing [...]

Kids love games of exclusion. This usually manifests itself in games of ‘keep away,’ having someone ‘catch cooties,’ or the ever-popular ‘No Brian club.’ [Rob] wrote in to tell us about the digital cootie detector he built. The cootie detector operates on galvanic skin response. It’s actually very similar to an E-Meter, although instead of Thetans this [...]

  [Rob] built this hexapod one day when he had some free time after work. Just like the last hexapod we saw, he based the build on the Pololu design which uses three servo motors for surprisingly reliable movement. The hardware is very straight forward. A Dorkboard serves as the brain. It’s a PCB that is wider [...]

  [Rob] Was cleaning out his car hole when he stumbled across a servo, a PC cooling fan, an Arduino and apparently a whole lot of bubble mixture. With all of this, some scrap timber and a few trips to the dollar store, he was able to whip up this bubble blowing bot to entertain his [...]

Creativity abounds in putting together this pair of Super Mario Bros. costumes. [Rob] and his wife didn’t stop with a well-assembled troupe of familiar wardrobe items, but decided to go for authentic sound effects as well. It started by finding a few of his favorite Mario sounds on the Internet. From there he grabbed a [...]

[Rob] just finished reinforcing a cheap drill motor. He picked up the tool at Harbor Freight and ditched the case. The plastic retaining ring was replaced with a thick metal washer which he machine The washer uses three bolts to attach to the mounting plate that he welded together. We’re not exactly sure what he’s got [...]

[Rob] has made an astounding contribution in the effort to keep our libations chilled. Not content with merely refrigerating his cold ones, or even putting them in a cooler full of ice, he has built a beer caddy out of solid ice. Though it may look simple initially, you can see from his writeup that [...]

[Rob] sent us some information on how he converted his flux-cored welder to a metal inert gas welder. He used a piece of DOM tubing as a collet with a side inlet tube that he uses to inject carbon dioxide. The gas is sourced from a 12 ounce paint ball CO2 tank and it looks [...]

Find yourself an old record player, a laser level, and a digital scanner and you can build a 3D scanner. That’s what [Rob] did. The camera and laser level are mounted on the turntable for steady rotation. The camera captures the vertical laser line traveling around the room by recording 30 fps at a resolution [...]
