The Glass Recycling Game

bottle-bank-arcade

Operating under the premise that glass bottles were not being recycled as much as plastic or aluminum because there’s no payment for the effort, the team at The Fun Theory set out to add a non-monetary incentive. Here is the fruit of their efforts, the Bottle Bank Arcade. Now recycling glass bottles comes with a bit of a game.

A light flashes above one of the holes in the recycling bin and then rewards points if a bottle is inserted there quickly enough. This Simon says type concept proved incredibly popular in the video embedded after the break. We would image some of the kids in the video made their parents haul them home and back with some empties so they could play.

In one evening, this modified bottle bank was used over 100 times, while a nearby low-tech repository was used just twice. This is a great way to use some tech knowledge, a love of hacking, and desire to spread joy in order to make the neighborhood more fun and help increase the amount of trash that ends up being recycled. This is the same team that put together the musical subway steps, we hope they keep this trend going!

Polycarbonate Fish Uses Three Servos To Swim

polycarbonate-fish

[Amnon] is learning the hard way that water and electronics don’t always like to play nicely together. He’s been working on creating a swimming fish that uses three servos to flex a sheet of fish-shaped polycarbonate. This photo doesn’t really do the project justice but you can get a better idea of what he’s accomplished by watching the videos after the break.

The three servos along with some distance sensors for obstacle avoidance are all controlled by a PIC 16F877A microcontroller. [Amnon] tried out three different waterproofing methods; coating the device in varnish, dipping it in hot glue, and dipping it in epoxy. The first two resulted in water damage to the electronics, but the third managed to work. It kept the water out, but also prevents reprogramming of the controller.

Although not successful, we would have loved to see the process of dipping the fish in a churning vat of molten glue. Once perfected, this may be the perfect platform for carrying our weapons of doom.

Easy Touch Capacitance

[Humberto] from NerdKits is one of our favorite tipsters. We like how he can take a concept that seems so extremely complicated, in this case touch capacitance sensing, and present it in a clear and concise manner thats impossible to not love. As previously mentioned the most recent NerdKits hack is on touch capacitance; by using a resistor capacitor pair and some clever switch timing, anyone is able to detect the presence of a human limb. Now who’s going to be the first to adapt this concept further in their own hack?

Tying The Knot With MakerBot

makerbot-ring

De Beers would have you believe that only diamonds will do, but hackers are hardly ones to follow convention. How better to say “I love you” than with a MakerBot-extruded black ABS engagement ring? [Adam Elkins] did just that, creating the design with a combination of GIMP, SketchUp and Blender, then producing the final output on a MakerBot at Philadelpha hacker space Hive.

From the steampunk wedding at the 2008 Maker Faire, to the science-meets-romance web comic xkcd, hackers certainly have some unique ways of expressing their devotion. What are some of the wildest or most charming that you’ve seen? Comments are open…speak now or forever hold your peace.

Oh, and the engagement ring? She accepted. Congratulations to the lucky couple!

Mouse Runs Through VR Maze

vr_mouse_setup

In an effort to determine the brain of animals during movement, scientists have built this contraption. It is a VR pod for a mouse. While we’re pretty sure/hopeful that none of you need a mouse VR system, we think the rig is interesting enough to stand on its own. It appears to be a convex mirror setup, projected in a dome. The controller is interesting in that it looks like a giant trackball hack. They’re using an optical mouse rigged to a ball floating on a cushion of air. This makes it much easier for the mouse to move. There’s a video of the whole thing in action after the break.

Skittles, The Robotic Blimp

Blimp 4_0

Funky Shiitake Mushrooms, a high school design team from Fremont, CA, have created a low cost airship they call Skittles the Second. Skittles is a remote control robotic blimp, complete with 4 reversible propellers, wireless video, and 2.4 a GHz remote control. Somewhere between a regular RC  blimp and a Predator Drone, Skittles and FSM have managed to gain a large number of awards including winning the Digital Open grand prize. The ship performs amazingly, and can perform a full 360 in just over one second. There is a video after the break.

For the future, the group plans to give the ship autonomous capabilities, in order to avoid losing another drone in strong wind. Fortunately, after that happened to Skittles the first, they were able to hunt it down after it had floated 3 miles down the road. Since they are all high school students under 17, we would say they have a lot of potential. I, for one, welcome our new robotic blimp overlords.

RFID-enabled Robot…mood…tail…thingy.

moodtail

Furries: is there nothing they cannot do? Well okay, “shower” remains an elusive concept, but wearable technology seems to be in, as evidenced by this robotic mood tail. [Wei-Chieh Tseng]’s adorable Arduino-driven fashion accessory operates either via Wii Nunchuk or a set of RFID cards tagged with specific emotions to depict.

Details are scant. It appears to have been a project for a physical computing or design class. One thing’s for certain: Halloween is going to be awesome.
