Awesome DIY Electric Bikes Defy Laws, Good Sense

Firefly Edison


Building your own electric bike has many advantages over buying one. It’s cheaper: you can pick up parts from scrapyards or buy cheap off-the-shelf motors, and even a purpose-made conversion kit can be had for $400, a lot less than buying a new electric bike.

A home-made bike is also easier to maintain. Because you built it yourself, you know how to fix it.

But best of all is speed. To still qualify legally as a bicycle and not a motor vehicle, top speeds are typically limited to something around 15 mph, less than you can achieve with a good pair of legs. Strap an old truck starter motor to a beater mountain bike, though, and you can hit much more dangerous speeds.

Firefly Edison

The Firefly and Edison Trailer from Bryce Tugwell comes in at the classy end of the range. The bike itself is a simple conversion: a Bianchi Milano Citta, fitted with a 36-volt 700-watt brushless electric hub and powered by batteries kept in a beautiful hand-built box. But what really gets us excited is the Edison Trailer in the back. Made from the same wood as the battery-box, the trailer features a “drop-in Martini bar (vodka, gin, vermouth, shaker, ice bucket, lemons, limes, olives and 4 martini glasses).” I’ll take mine with gin, stirred.

Johnny Chung Lee makes DIY telepresence bot out of an iRobot Create and a netbook

Most of us don’t have $15,000 to drop on an Anybot, even though having one around would be nice in the event we don’t feel like leaving the house to get some coffee. To help those of us with more humble means, our old friend Johnny Chung Lee (of Wiimote hacking and Kinect dev team fame) has utilized his prodigious DIY talents to create a video chat robot for the relatively paltry sum of $500. Using an iRobot Create ($250), a netbook with Skype ($250), a cable to connect the two, and some control software he wrote himself, Mr. Lee built a digital surrogate on the cheap. Johnny isn’t the first person to so leverage iRobot’s hacking platform, but he added a stand on top of the robot to get the PC closer to human height, attached a fish-eye lens to the webcam for better remote viewing, and even did some re-wiring to allow the netbook to charge via the Create’s base station. The code and how-to instructions are up on his blog, so hit the source link if you’re feeling up to making one yourself. Seems like Johnny Lee’s putting that Google 20 percent time to good use thus far — keep ’em coming. Check the video of this latest creation after the break.

Lego shutter release for Sony NEX-5 lets Pikachu take your pictures

Need something to go with your colorful new NEX-5 Lego viewfinder? How about a Lego shutter release? It’s the next project by the same dude, who goes by the appropriate handle “cubie” over at the Digital Photography Review forums. This one requires a bit more work, soldering a couple of IR LEDs to a headphone jack and positioning them to sit atop the camera’s IR sensor. Then, by playing the right sound through an audio patch cable, pictures can be taken. Overly complicated? Yes. Love it? Pika!

[Thanks, Marc]

Pac Machina displays a trivial love of the needlessly complex

Now, you may look at this little project and ask yourself, “what is the point of this thing?” but that would, in fact, be the wrong question. The Pac Man-loving creator of Pac Machina needs no reasons, and honestly, neither do we. While we wouldn’t necessarily want one of these clock-like Pac Men in our drawing room, we admire the creativity and time put into what was surely a somewhat tedious project. We are huge fans of tedium, after all. Video is after the break.

Star Wars Fan Builds an AT-AT from Old Computer Parts

Welded AT-AT

If you have a pile of old computer parts in the garage or in a corner of your home office that’s been growing because you just keep “meaning to go to the recycling center,” but just haven’t gotten around to it, here’s the DIY project for you. Sage Werbock, a sculptor and Star Wars fan, has taken a bunch of old computer parts from his own collection and that of his friends and put together an incredibly realistic-looking AT-AT that’s over a foot high and weighs less than 15 pounds. 
All of the computer components used have been welded together, so this isn’t some heap of steel and aluminum held together by duct tape and twine. Werbock even welded some burn-marks and weapons scars onto the AT-AT to make it look a little more battle-hardened. If you want one yourself, you can head over to his Etsy page to find out how he made it: if you want this one, it can be yours for $450 list.

The Shaving Helmet Trims Your Mane Quickly

Shaving Helmet

I’m a firm believer that if or when my hair starts to recede, I’m just going to shave it all off – I’d rather go bald than look silly with patches of my hair missing from the top of my head, I just don’t think I could pull it off. Hopefully by then these three guys and their DIY head-shaving helmet will have secured the appropriate licensing required to sell their product on late night infomercials. 
The Shaving Helmet, as they call it, isn’t linked anywhere, doesn’t have a product Web site, and doesn’t seem to have the backing of any actual company. This video surfaced on YouTube a couple of days ago and was an instant hit. If the helmet – which promises to shave your head safely and smoothly with four blades in the top of the helmet and a system to automatically dispense shaving cream on your head while they work – is actually real, it could be a great invention.  
At the same time, the video could very well be a viral ad for some new Gillette or Schick product that will be released when the video is at the height of its fame. Until the details become clear, you have to admit: that’s a pretty cool invention. Hit the jump to see the video.
 

8-Bit Memory Turns Nintendo Cartridges into USB Hard Drives

NES Hard Drives

If you’re like me, you have a bunch of old Nintendo and Super Nintendo game cartridges lying around. They’re not good for very much these days, especially if you don’t have your old consoles plugged in to your television. Over at 8-Bit Memory, they decided to do something special with all of those old cartridges: turn them into external USB hard drives. 
The cartridges come in multiple sizes and flavors, and some are even USB 3.0 compatible. Simply select the game cartridge you want attached to your computer for extra storage, and how much space you want in it. For example, the Dr. Mario Nintendo game cartridge will set you back $129.99 retail for a 500GB drive, $149.99 retail for a 750GB drive, or $179.99 for a 1TB drive. 
If you’re not a Dr. Mario fan, you can choose the original Metroid Nintendo game, Excitebike, the original Super Mario Brothers, Killer Instinct for the Super Nintendo, and more. If the game you’d like isn’t listed, you can request it, and 8-Bit Memory will find the game and turn it into an external drive for you.

Flamethrower Gloves Look Awesome, Torch Everything

Flamethrower Gloves

If you think this is some kind of secret military project going on behind the scenes at DARPA, you’d be wrong: these DIY flamethrower gloves are actually the product of the special effects and design team at J&M Special Effects, who were interested in coming up with a system that could shoot real flame from a stage or movie set performer’s hands with very real effect. 
The guys at J&M note that the system is a prototype, and they’re not finished working on it: future iterations will be more compact and the hoses for the propellant will be streamlined and closer to the performer’s body so they can be hidden under clothing or a costume. 
The end result looks amazing, with the flame literally erupting from the palms of the wearer’s hands. Hit the jump to see the full video. 

RFID poker gets DIY kit, automated card counting now available at home (video)

RFID poker gets DIY kit, automated card counting now available at home (video)

When Andrew Milner built himself an RFID-equipped poker table and the automated video overlay system to match, it was certainly a labor of love. Now, like any good poker player, he’s trying to get a little money out of it. He’s selling a DIY kit that includes almost all the hardware and software you need to replicate the video below but do it on your game night with your friends. (You’ll need to supply the webcams, a table with cutouts, and a Windows PC to handle the footage.) This means you can create video replays that look awfully professional even if your ability to calculate odds on the fly and to focus more on the river than the bowl of chips is decidedly amateur. Components can be bought individually, like a deck of RFID cards for $148, or you can get the entire kit for about $1,600 — stakes a bit too high for our game.

Makedo Connects Junk Together. The Best Kid’s Toy Ever?

I have one question for you, God, and I want a straight answer: Why wasn’t the Makedo around when I was a kid? I’m serious. Back then I was like most kids of the 1970s, and the box a toy came in was more exciting than the toy itself (often the toys were the same drab beige as these boxes). The day my parents got a new washing machine was one of the best in my so-far short life.

And with Makedo that day would have been around one zillion times better. Mekedo is a pack of parts to help you to make anything from the scraps plastic and card around the house. There are three different pieces. One tool, which is a saw made from plastic with a spike in the handle to drill holes in card.

The other two are fixings. There’s a two-part pin-and-clip for joining sheets together, which works like a cross between a zip-tie and a rivet. Then there’s a lock-hinge, which is joined to two pieces of card with the pins and does what you think, letting you lock it open at any angle. And that’s it.

But like that washing machine box, which had the potential to become anything, these simple tools and fixings extend the possibilities even further. They let you put in doors, add heads to robots, put (spinning) rotors onto helicopters. I can honestly say that Mekedo would have been the best toy I could have gotten back in the dreary 1970s.

Thanks a lot, God. If time travel is ever invented, I’m going back to my six-year-old self and telling him to skip Sunday-school. Total frikkin’ waste of time.

Kits start from $25.
