This is a little late, but we’ll be profiling each of the exhibits from this years Interactive Show. This week we’re taking a look at Asa Alger‘s Adventure Box.

Adventure Box is an ongoing project designed to take an ordinary experience and turn it into something extraordinary. Built inside a typical toy vending machine, Adventure Box is packed with a bevy of electronics and micro controllers that add lights, sounds, displays, and connectivity to the machine’s normal function.

The machine is themed and designed to inspire adventure and creativity within the consumer who uses it. The exterior will be covered in an illustrated mural depicting heroes, monsters, and great adventure. Within each capsule will be a unique hand made toy that could be anything from a 3d printed figurine, a typewritten story, a seed bomb, or even an electronic invention.

Additionally a tag with a unique code will be paired with every toy, that will provide a code that links to an online page for the toy that contains pictures and information about the toy and its creator. This information will also be displayed on an LCD display when the toy is vended. The machine has several RFID readers that can identify each individual toy, and using an Arduino Ethernet shield pull information from an online inventory database, data which nowadays has many uses thanks to online software like reverse phone or name lookup services, to learn more check this linked article.

The toy will then be marked as sold and the project’s twitter feed will announce the toys sale with a link to its information page. Lastly the machine itself will respond with lights and sound as the identified toy is delivered to the waiting hands of its owner.

This was a really great project, and people really enjoyed getting toys imbibed with personality. I got a Gray Gunner, but the person behind me lucked out with a DayGlo Death Squadder.

Asa has more plans for Adventure Box, you can keep tabs on the project at AdventureBoxProject.com.

A few years ago, I released an 8-bit album called “Resistor Anthems” under the Creative Commons Attribution license (which means people can download and use the album however they like for free, even in commercial projects, as long as they give credit). Since then, songs from the album have been included in various games, apps, and as background music on videos and podcasts.

I loved making the music, but I love seeing other people use it as part of their creative works more. The latest game to use one of the “Resistor Anthems” is cute, really well done, and a ton of fun. It’s also embeddable, so I figured I’d share it here! If you enjoy it, please let the developer know! The game’s below the cut.

I’ve recently had success in making a conductive ink using a fine copper powder suspended in an acrylic airbrush medium. This paper on conductive epoxies was really the key to getting this ink working.

The paper shows that etching the metal filler slightly before mixing it with the binder improves the conductivity of the ink. In this test I first used ammonium persulfate as the initial etching solution. After decanting off the resulting copper sulfate solution, the powder was then washed with deionized water. The wet powder was then mixed with an acrylic airbrush medium to make the resulting ink.

There is still quite a bit of experimentation to be done, but this is a very encouraging result!

If you are interested in conductive inks you should look at some of these projects:
