"It is okay as long as you remember both green and red are the colors that can not be seen by those with color blindness. And that visual defect occurs more commonly in men.
Do you know if they are adding the color for the front…"
"Good point. The low cost iPhone cameras are also opportunities for teaching moments. It is easy to construct cases in which the user or the camera might produce "incorrect" results because the operator wasn't looking for…"
"The resolution and sensitivity of the kickstarter version -- makes it mostly a novelty. Mu Optics is now nearly seven months behind their original estimated delivery schedule, I'm they will finally deliver a year after their…"
"Probably closer to $70... I've been buying at about $35/tube in singles... The life of LED tubes are about twice as long. Half the lumens... Instant start, no hum, no flicker.
Tubes are still on the watch list. Prices have…"
"Sorry, I couldn't resist ... (PIX below) the bulbs below were collected in my house over a several year period. As the bulbs failed, or took long enough to warm up that it no longer -- was safe. You could walk in and out…"

"The white stuff -- is probably combustion by products. And I might be expected. You would not normally see them on the white sch40 pipe. Sometimes a gentle push on an inspector is more useful... you may see his work again... or he…"
"Sometimes the problems are not with the architects... but with the trades. Sorry guys (and I'm not an architect). But I've seen wires, ducts, and piping placed not where it was recorded on the drawings... but where it was…"

You may want to look at NEST, I believe they…"
