Motorcycle Throttle Bodies For Your Car


[Dem_z] modded his Honda VTEC engine to use a set of individual throttle bodies from a 2001 Suzuki GSX-R motorcycle. The fuel injection bungs on the throttle bodies were epoxied shut and the bodies were only used to provide individual butterflies for each cylinder. This one doesn’t quite make our to do list, but it’s definitely a hack.

[bender386] caught my blunder first, so I’ll be sending him a bit of Hack-A-Day swag. In the meantime, here’s a little bonus: Check out this home built anamorphic lens. Native 2.35:1 projectors have started showing up, but they’re insanely expensive. By adding some image processing and a lens to stretch the projected image, you can get full width projection and use all the pixels on the projector.

Evil Mad Scientist Laboratories Turns 2


Evil Mad Scientist Laboratories is celebrating their second anniversary. They say they’re now 20 millicenturies old. To celebrate, they put together their greatest hits from the last year. We enjoyed their bristlebots, candyfabbing, and AVR business cards and hope to see their work for many more years to come.

Turn Signal Jacket How-to


[Leah Buechley], whose work we’ve been covering since way back when, has built this lovely turn signal jacket. The project photos were posted in March, but she’s just added a well illustrated project guide. The jacket is based around a LilyPad Arduino, a lightweight Arduino board with radial pads designed to be used in wearable projects. You make your connections by sewing conductive thread through the pads. The how-to covers attaching the LilyPad parts properly and then insulating the wires with fabric paint after you’ve verified they work.

The guide has an interesting discussion about placing the power supply. The 4-ply silver coated thread used has a resistance of approximately 14ohms/foot. So, if you place the power supply one foot from the LilyPad, the two wires combine for 28ohms, causing a 1.4V drop. The power supply is only 5V, which means the LilyPad will be 3.6V. A voltage of 3.3V will cause the Arduino to reset. If your resistance is too high, you’ll have to add more thread.

The power supply on this jacket is under the collar. Each cuff has a single button plus an LED. The button will make the jacket flash the direction for 15 seconds (also indicated on the sleeve LED). If you press both buttons at the same time, it switches to night mode by flashing both directions at the same time to make you more visible.

Confessions Of A Wi-Fi Thief


A wry editorial on Time Magazine’s site about tapping into your neighbors’ Wi-Fi tells of how the author [Lev Grossman] stole internet access from his neighbors’ open networks for years. He finally decided to pay for his own connection, which he fittingly leaves on an open network. He makes the point that leaving it open is a violation of his TOS agreement, but he doesn’t seem particularly bothered by the notion of people tapping into his network.

[Bruce Schneier] takes an even stronger stance on the issue, suggesting that it is not only safe to leave your network open, but a matter of politeness toward your guests, similar to providing them with basic amenities. He also mentions that if your computers are not adequately secured, network security won’t make much of a difference. We tend to agree with [Schneier] on this: we also leave our network completely open.

That’s not to say [Grossman] doesn’t have a point about the unreliability of pilfered internet access, noting “I always seemed to lose connectivity just when I was about to send a crucial e-mail.” Sure, we leave our network open, but we have to pay for our internet access. We really can’t afford not to. One thing [Grossman] didn’t mention (neither did [Schneier], but he wrote his article before this happened), is that a Maryland bill that would criminalize leeching Wi-Fi has been shot down. The first legislation of its kind, the defeat of the bill mean citizens of Maryland are free to leech from open networks without fear of prosecution, but it sets a precedent that may influence future rulings.

HMD Try Out For Gizmodo Commenters


We had a decent response to our HMD post, but $400 might be a little too steep a price to pay for the Zeiss Cinemiser glasses. Luckily, Zeiss is offering registered Gizmodo readers the chance to try them out free for two weeks. All you have to do is comment on the Gizmodo post announcing the offer with a registered Gizmodo account, then fill out some information on a form Ziess has set up for this offer. Of course, you have to provide them with credit card information (just in case you break the glasses) and a great deal of feedback from the experience, but it’s far more preferable than shelling out $400 to find out you don’t like the glasses.
