  • Research and shop around for a type of fan called a centrifugal blower or utility blower. These fans are designed specifically for entire space ventilation. They sound like tiny jet engines. The same fans that inflate bouncy fun houses or the fans you sometimes see on a storefront wet floor during a rainy day to blow dry. Output rates of small units 100 to 500cfm (cubic feet per minute) will replace all air inside a 2-car garage space every hour. Mid range blowers 600-900cfm will replace that same air space every 5-10min (approx. 6x per hour). Higher velocity blowers >1000cfm will clear an entire 1-story house (typically for HVAC or factory use) and is more efficient and quieter than the biggest attic fan style unit.

    After you have bought the raw power of air movement, then experiment with positive pressure and negative pressure flow setups (suck vs. blow). And then finally other per room or per window configurations as needed.


  • This is interesting. I use OTA antenna tv everyday, almost exclusively. I almost forgot OTA HDTV still uses the mpeg2-ts, similar to the dvd codec. Newer tv hardwares (>2010-ish) all can decode mpeg4, theoretically, since they utilize internet streaming apps and services.
    I smell a new format war a comin’.
    I say, go right for mpeg4 h.265, or higher. Instead of mixing mpeg2 and mpeg4, like the video demonstrated. Because no way am i going to “buy” a DRM-protected thing for every broadcaster… I’m currently pulling-in 20+ stations.

    And that may be the other format war… to pay or not to pay.












  • Ahh, the beloved VCR! Also while recording, pressing pause to leave out the tv commercials, forgetting to unpause, the station interrupting news breaks, a low-flying airplane messing up the tv reception, someone changing the channel while you went to go to the bathroom. And my all-time favorite… dad placing his big brand new stereo speakers right next to the little videotape shelf!
