Sandbox Game In A Sandbox

July 3, 2011 by Brian Benchoff 21 Comments

The team at Monobanda have been working on a sandbox game called Mimicry that uses a Kinect to read the terrain of a sandbox.

From the teaser video and press release, the eventual goal appears to be controlling both a character in the game and the environment simultaneously. By reading the terrain of the sandbox with a Kinect, the team was able to import that into the game world. The team says the game world is inhabited by tiny virtual characters that, “roll around, jump and glide through the Mimicry world.” Anyone playing Mimicry can create obstacles for these little creatures or build them a race track. The Monobandia team says the point of this game is, “to create your own games.” With a fully editable world and its ‘rolling ball’ inhabitants, we can’t wait to make our own custom Beyblade arena.

Since the release of the Kinect SDK a few weeks ago, we’ve been seeing some really amazing projects that should have been day-1 demos from Microsoft. We’ve been impressed with the projects we’ve seen so far, and can’t wait to see what others come up with next. If you have a neat build, be sure to send it into the tip line.

Check out a video testing the game mechanics after the break.

Enhancing Simple Circuit Kits With Microcontrollers

June 24, 2011 by Mike Nathan 12 Comments

[manuka], aka [Stan Swan] is a teacher in New Zealand who enjoys enlightening his students on the wonders of electrical circuits. He primarily uses “snap connector” circuit kits, sold under the BrainBox name in NZ, for his interactive labs as they can be easily manipulated by pupils of all ages.

While the kits are great, he says that the range of experiments they provide can be a bit limited, so he decided to swap out the kit’s sound module for something far more useful – a PICAXE-08M. The space left by removing the sound module was pretty small, but [Stan] got everything to fit without too much hassle. His modification allows his students to program the PICAXE, as well as utilize four of the uC’s output pins.

Needless to say, the addition of the PICAXE module was a huge hit with his students, allowing them to create far more exciting circuits. [Stan] has been revising his system over the years, adding extra output pins, enabling lamp and motor control, as well as tweaking his setup to respond to IR commands.

We think [Stan’s] work is pretty awesome, and we’re still wondering how this flew under our radar for so long. He says that his students vary from preschool kids to centenarians, so if you’ve got someone that you would like to introduce to the fun world of electronics, we suggest picking up one of these kits and getting to work.

Slot Car Lap Timer/counter

June 17, 2011 by Mike Szczys 4 Comments

For his first project using the TI Launchpad [VOJT4] built a lap timer and counter for slot cars. For us it’s always hardest to come up with the idea of what to build and we think he found a great one here.

Each time a car passes the finish line of the track it trips a reed switch that was hot glued to the underside of the track segment. Both reed switches have a capacitor to smooth out the inputs (is this acting as a hardware debounce?). The time and lap number are then pushed to a graphic LCD by the MSP430G2553.

You must be logged into the forum where [VOJT4] posted the project in order to see the images. Because of this, we’ve embedded them (including the schematic) after the break along with a demo video. But do take a look at his project thread to hear his thoughts and peruse the code he wrote.

Blox That Play Back

June 14, 2011 by Nick Schulze 3 Comments

I’m sure most of us remember playing with blocks when we were kids, well now this age old children’s toy has been crammed full of electrical goodness by a team of Electrical Engineers from the University of Texas. The Blox, which are about the size of a standard Rubiks Cube each contain 16 IR sensors, 4 touch panels, a 3-axis accelerometer, a ZigBee Wireless Module, a 2″ OLED display and a battery, all controlled using an ARM Cortex processor.

The Blox show their full potential when used together as an interactive distributed computing system. Blox is an open source project so all of the build details, schematics and code can be found on the website. For an overview and demonstration of the Blox check out the video after the break.

An Autonomous Car Using A “Webcam”

June 13, 2011 by Jeremy Cook 8 Comments

This autonomous remote control-style car from Cornell students was designed for a senior level engineering course there. It’s main “sensor” is a low-res webcam style camera. As shown in the video after the break, this car does quite well staying within two black lines on a white surface using it’s vision processing. It also has an IR sensor to detect objects in front of the car and stop without crashing.

All “vision” computations are handled by an Atmel Mega644 MCU, an 8-bit processor. Because of the processing limits of this chip, much work had to be done to make this process computationally efficient. These students go through an incredibly detailed account of their project, focusing on the code and electrical design. Check out the video of their car in action after the break.

Tablet-controlled Disco Droid

We have seen a few neat Google ADK projects pop up since its announcement a few weeks back, and this one is already on the list of our favorites.

YouTube user [chrisjrelliot] has put together a great hack demonstrating the ADK’s power and how easy it can be to control devices in real time with an Android-powered device.

He hacked apart an Android figure (naturally) and fitted it with some LED eyes as well as four servos. The servos are used to rotate the head, body, and arms of his Disco Droid, all of which can be controlled via his Android-powered tablet. As you can see in the video below, he is able to control the Droid’s actions in real time with a few simple swipes of his finger. One thing we did notice is that his tablet is not connected to anything via wires, so we are assuming that there’s a Bluetooth module hidden away somewhere in the mix.

While the video is a bit short on details, [Chris] promises that source code and build plans will be published in short order.

Electro-static See-saw

May 17, 2011 by Caleb Kraft 3 Comments

Many of you may have seen these fun little toys in museums or possibly even in school. Instructibles user [brazilero2008] takes us through the process of constructing one on our own.

Most of this toy are constructed from fairly household materials like foil, paper, straws etc. The fun part comes when you find the power supply. [brazilero2008] is using an air ionizer that he found at a rummage sale, though any high voltage DC source should work. He shares some tips on how to save time and effort creating the balls on the end by telling us how he did it the difficult way.

We admit this isn’t the most attention grabbing project, but we think it would be a fun educational weekend project.
