Automated shooting range

targets

[Steve] was discussing airsoft with a friend when he came up with this idea. His friend was lamenting the lack of “action” style targets for their airsoft hobby. [Steve] took this as an opportunity to make his own automated target system. The targets themselves are made from Construx, a paper target and a piece of cloth to stop the airsoft pellets. Controlled by an Arduino and an ioBridge module, it has a web interface so he can switch programs from up range. You can see a video example of him shooting some targets after the break. Next,he should make it twitter where each target was hit.

Refillable CO2 cartridges

co2

For those who use these little cartridges, you know how quickly the price can add up.  [steve] takes us through the process of adding a valve to a spent cartridge so it can be refilled. Over all, it doesn’t seem too difficult, and [steve] offers lots of tips to increase longevity and reliability. It isn’t very often that we show a hack here that doesn’t involve some kind of electronics, so take a break from the resistors and microprocessors for a moment and enjoy.

Gears embedded in business cards

In [Bre Pettis]’s latest “things” video, he talks with [Adam Mayer] about his geared business cards. [Adam] has designed several versions of these cards that have functional gear systems in them. There appears to be a simple two gear one and a more complicated planetary gear set up. The designs have been uploaded to Thingiverse, so you can download and build your own.

WEEE Man

weee

WEEE Man is an art display that has been roving around England. No, he doesn’t walk or talk. He is here to remind us of how wasteful we can be. Hackers rejoice, we’re part of the solution. It also doesn’t hurt that he is Seven Meters tall and over three tons. WEEE Man looks awesome, but are we the only ones that spotted stuff and thought “ooh, I could have used that for a cool project.”?

Rocket camera

[Jordan] sent us his Rocket Camera project. It really isn’t much that we haven’t seen before, but we thought many of you would be feeling the effects of gravity a little harder today. So when your belly is stretched to its limits with Turbaconducken and you don’t think you can stand, take a little flight with [jordan]. Careful you don’t lose your lunch on the way back down though.

Red Bull Flugtag Portland


Off all the competitions for poorly performing human powered flying machines, the Red Bull Flugtag is one of our favorites. Honestly, it’s the only one we can think of, but that doesn’t mean we’re any less enthusiastic about giving flight to half baked ideas. Today was the Portland round of the international event. Teams have to submit an application for their craft in advance. The vehicle can have a maximum wingspan of 30 feet and a weight with pilot of 450 pounds or less. Power is from muscle or simply gravity. The vehicle also has to be easily retreivable so they can get it out of the water. Judging isn’t just for distance, but for creativity, too.

Flickr users [pdx-kate] and [Jabin] have uploaded images and video from the day: The winner was Team Yakima’s big wheel that flew 62 feet. Second place went to Greased Lightning at 55 feet. Third was the FreeBallin sneaker which you can see in flight here. The People’s Choice award went to the Space Balls Winnebago, which we unfortunately can’t find a very good picture of. You can read more about each individual entry on the results page.

Embedded below is the video of the current US record holder: a banjo that went 155 feet in Nashville. The next US event will be September 6th in Chicago.
