  • Product SEN-12705 | about a month ago

    Looks like the spectral response of this sensor may be too high for use as a flame detector. I understand that flame detectors in use now detect wavelengths lower than 300nm (http://en.wikipedia.org/wiki/Flame_detector). Don’t know if this value is from precedence (what already being used) or from practical (what is best). Oh well, like the datasheet says, I could always use it for bicycle navigation (huh?)

  • Product TOL-11704 | about a year ago

    Why not just make 10 hotter and make 10 be the top number and make that a little hotter?

    I think you have the speaker polarity switched. Rush Limbaugh sounded like he was 180-deg out of phase.

    That mohawk makes you look udder'ly ridiculous.

  • News - A Few Upcoming Classes | about 3 years ago

    Most of the times I use alcohol. But if I have a sensitive circuit or I want it to look real good I use Windex. The small amount of ammonia in it cuts the flux like no other and is safe on other components and yourself. I’ve used this very successfully on high impedance crystal circuits that wouldn’t start. Some fluxes, which are pretty high impedance themselves, are sometimes enough to affect their operation. Most cleaners I’ve found smear the flux around and after a rinse leave “snail trails”. Use with toothbrush or cut-down acid brush with the Windex and follow by very hot water rinse, dab with paper towels to dry.

    with a little more software you could make it a Rock, Paper, Scissor, Lizard, Spock playing glove.
