There have been some great wrap up posts from the Houston Quilt Market floating around the craft blog circuit. One of my favorites, though, is this behind the scenes look at the production of the Michael Miller booth, which took home the Creativity Booth Award. It’s an interesting look into how they went from concept […]
The first presenter at last Thursday’s Dorkbot Austin was a gentleman named Mikal Hart, who described his “Reverse Geocaching Puzzle.” Designed and built as a wedding gift for an old friend moving to France, the box incorporates an Arduino with a custom shield. A prominent button on the lid, when pressed, returns a distance, in kilometers, on the LCD display (if a GPS signal can be acquired), and counts button-presses up to 50 atttempts. No directional information is provided, so the box must be moved about in order to triangulate the location it wants. Mikal also included a cunningly-disguised back door to allow it to be opened in the event of battery failures or bugs.
From the MAKE Flickr pool Matt the modulator picked this rather sweet 80’s Maplin Harmony Generator kit on ebay. Though nonfunctional after the initial assembly, a bit of rewiring got things up and running for the above-seen demo processing a Gameboy/LSDJ sequence. He was also kind enough to post the relevant schematics/article for those interested.

These industrial robots move at inhuman speed while deftly maneuvering in unison and maintaining a sub millimeter tolerance.
Netbook hacker Rob928 created this excellent tablet mod by tearing apart his Dell Vostro A90 netbook, adding a Hoda Technology solderless touchscreen kit, and filling in the gaps with plastic epoxy.

Though some of the fuller featured multimeters offer similar abilities, this ATMega8-based transistor tester project, identifies pins, measures gain, plus resistance and capacitance. Looks like a welcome addition to the workbench – schematic + source code can be found here [via Electronics-Lab]
