I bought a toy foot pedal for $10. I didn't know how to communicate with it, but for some reason that didn't bother me until I had it in my hands and was wondering what to do with it.
Today I received a Microchip ChipKIT wifi shield courtesy of Dangerous Prototypes — and there should be a ChipKIT Uno32 coming along soon, too. I'm looking forward to using this to prototype some kind of web-enabled brewing system. It's good times at the Magic Smoke Brewhouse & Grill!
My flux pen recently bit the dust. Fortunately the raw material was close at hand. Making solder flux from rosin is a snap — and a pine tree near my house was oozing big dollops of gum.
Can't afford a Big Green Egg? You can build a ceramic smoker from a flowerpot in a matter of minutes — Alton Brown showed how on "Good Eats". Here I show how to add temperature control to your flowerpot smoker so that you can "set it and forget it". With automatic heating you can take the fiddling and guesswork out of using your smoker... and still have an excuse to hang out in the garden drinking beer.
