Rotary encoder based cooking timer |

 Continuing my experimentations with cooking timer user interfaces, I stumbled upon a cute little rotary encoder on Sparkfun. It immediately looked like a good match for the project. The thing is that all cooking timers I’ve seen have either a simplistic interface requiring many clicks to set the time (like clicking the “minutes” button 50 times) or a complex keypad with way too many buttons.
At first I thought I'd need 2 axes (axis 1 would increment by 1 minute and the other axis by 15 minutes) but fiddling around with the trackball showed me that it was not necessary; that I'd just need one axis with tactile feedback (that is, a clicky switch rather than a smooth flowing motion of the controller) and some selection mechanism to switch between 1 and 15 minutes.

Review: Dremel 220-01 stand vs. Proxxon Micromot MB 140/S |

Started fabricating PCBs at home using the toner transfer method and needed to find a way to drill them, as I am still mostly using through hole parts. Since I was pleased with my Dad's dremel 300, I thought it would be a good idea to get one for myself along with a Dremel 220-01 (220) drill stand. It took me a few minutes of painful work with the stand to realize just how bad it is for the job - it flexes, it's plasticy and it's an insult to Dremel users.

Switched to JComment from yvComment (will restore old comments soon). I thought I could finally get rid of that annoying CAPTCHA, but it turns out I had started receiving junk comments within minutes of disabling it. The internet is such an evil place. |

I recently purchased an ATI radeon 5850 and could not get it to work on my Windows Server 2003 R2 machine. The Catalyst drivers simply aborted the installation claiming incompatible OS and such.

Threw out the article index on the front page, added a news section. Kind of made more sense. |
