Well-written and valuable for insight whether you have similar personal experience or not. As someone who does hardware and software as well, I relate to the challenges of making something you can hold; it's very easy to underestimate the challenge difference between the two. Your Murphy's law references are spot on; I feel comforted reading I'm not the only one this happens to! Misery does love company, and it's imp…

When I read the "I had no prior experience in hardware; I was counting on being able to pick it up quickly with the help of a couple of mechanical/electrical/firmware engineers" I was ready to curl up into a foetal position... the fact that the author actually got something like this manufactured and shipped is nothing short of miraculous, it's not just a board off JLPCB and a plastic case, this involves custom manuf…

Looking back I agree it was miraculous lol, I don't know if I'd do it again...

Earlier quoted context omitted.

The controls weren't working because we had wired them up according to the labels which were wrong (which is also why the measurements didn't make sense to us).

Ah. A lesson from somebody who's built hardware that I'm sure you've now learned: make sure connectors can't plug into eachother unless they're supposed to. Even if they're different connectors, different keying, whatever, sometimes they can still be forced together.

I built a lot of Ikea last month. And I was just marveling how cleverly designed everything was so that it was quite difficult to put two wrong pieces together. Mostly, the only warnings in the manuals were to rotate a piece correctly.

Very interesting. I would like something like this, but not with LEDs.

Hydrargyrum medium-src iodide lamps are an alternative (artificial sun lights for movie sets), but you'll want a good AC unit in your office

I thought hydragyrum was a made-up word, but it's the Latin word for mercury, which explains the Hg chemical symbol. (Just in case anyone finds this interesting.)

50k lm is quite high. What electric power consumption does it have ? I estimate around 500 Watt, am I right ?

It's 60k lumens now, and it draws 580W off the wall

Whats the expected life for the leds at that power draw level?
