Earlier in the week, we covered the Boston Globe piece about the Moonbeam, a three-wheel microcar. Bre Pettis pointed me to builder Jory Squibb’s website where he has background info, numerous pics, video and a “How to Build Moonbeam” project journal. How to build Moonbeam, a 100 MPG microcar – Link
To control a lot of components, especially motors, physical devices or bright LEDs, you typically need to accommodate more current than your typical microcontroller can provide. Eric Wolf wrote a nice introduction for using transistors as a current amplifier to solve this common scenario. In regard to current capability, generally speaking, most microcontrollers will only […]
Martha Stewart Kids is now on newsstands, with some cute ideas for summer parties (my birthday was always lost during the Christmas holidays, so I pined for a fun summer party): “From themed birthday parties, to scrumptious cookie cakes and irresistible goody bags, the Summer 2007 special issue of Good Things for Kids is chock […]

Remember when your momma used to tell you: “Wash your hands after touching that money. You don’t know where it’s been!” Well, now you can reply: “I do so! Let’s see: it first showed up in Dayton, Ohio, five years ago, at a Sonic drive-thru, then it headed south, then west, spending a lot of […]
The creator of MacGyver challenges you to retrieve your keys from the bottom of a 15-foot crevice in the desert. The Scenario: Thinking you could use a new hobby to get you off the couch, your significant other gifts you with a metal detector for Christmas. After digging up loose change in your backyard and […]
The latest piece on uC Hobby explains how-to use low-amperage microcontroller signals to control high-current devices. Among other things, it explains how to use transistors to get from the logic of a MCU to the power needs of a motor. uC Meets BJT – [via] Link
