  • I’ve been happy with the GE Enbrighten series, though they do require a neutral wire. I use the Z-Wave models, but I can’t imagine the ZigBee models would work any differently.

    Neat feature of the Enbrighten line is they recognize several gestures including short tap, long press, double tap, and I think even triple tap. I configured mine so that short taps on/off toggle the lights between off and 100% on, long press on/off brightens/dims, and double tap on activates the preferred evening lighting scene.

    I think Minoston are also a GE product line? Again, Z-Wave, but rated for higher wattage in my case. They also require a neutral wire.

    I had a pair of no-neutral ZigBee switches sold as ‘Martin Jerry’ brand, but they were super dodgy. Terrible feel to them, and they made a sort of electrical whine when the fixture was on. I pulled them right out and sent them back.





  • You could source a pair of gigabit media converters and a length of fiber on Amazon for about $100. Just use the media converters to extend the Ethernet port from where the Internet hands off in your house over to your office. You can affix the fiber along baseboards and up over door frames with adhesive cleats and zip ties, or those nylon staples on a nail they use to tack down coax cable.

    If you’re willing to spend a little more on the fiber for a custom color, you can probably even order the fiber in a more neutral color than SMF yellow to blend into the trim better.

    The rankness of a fart can be expressed in decibel-Farts (dBF), a logarithmic scale where dBF = 10 log10(F1/F2).

    Characterizing F in standard units is a bit of a chore, but broadly speaking the resolution concentration of hydrogen sulfide (H2S) in air for humans-- the concentration at which 50% of people can detect its odor-- is about 4.73ppb, or 4.73 x 10^-9.

    A cubic meter of air at sea level (1 atm or 760mmHg) at 15°C contains about 2.53 x 10^25 molecules of mixed gasses. Scaling to a cubic meter, the volume for detection of H2S for humans would be about 1.19 x 10^17 H2S molecules per cubic meter. This value is your F2, our reference intensity for detecting farts.

    A typical human fart has a concentration of anywhere between .001ppm and 1ppm of H2S concentration, or between 1x10^-9 and 1x10^-6, or scaled to between 2.53x10^19 and 2.53x10^22 H2S molecules in a cubic meter of air.

    Therefore the rankness of a typical fart could be expressed as a decibel ratio vs the resolution density falling somewhere between 23dBF and 53dBF.

    This is a useful expression of rankness for modeling attenuation over time, accounting for dispersion, wind drift, and distance from the zero point.
