  • Rant: Tricking people into “Liking” your stuff on Facebook

    The whole Facebook "Like" button is getting out of control. I don't really mind sharing the "like" information with websites, but I do mind websites that try to trick you into liking something. It's the same lowball approach the sites that have invisible ad click areas in the whitespace to the left and right of the page. They aren't accurately capturing intent.

  • Update to .NET Gadgeteer Larson Scanner

    So, I got to thinking (with the help of some friends) about the current sourcing capabilities of the pins on the Gadgeteer main board. Modern microprocessors generally aren't set up to be able to provide much current to things like LEDs. I  saw a fair bit of that with the results I was getting with the scanner. So, what about wiring in reverse? LEDs can be wired in two differen...

You can use them as speakers as well as microphones and sensors. In fact, I beli...

    Happy 11/11/11! For those of us who grew up in the 80s, the back-and-forth red lights on the front of KITT and the Cylons was considered a really awesome effect. It's still popular today, and is even named after Gary Larson, the person responsible for those shows. Now, a good Larson scanner uses some PWM to modify the intensity of the LEDs trailing the leading light. With th...
