A big thing not often spoken about with eye strain is dry eye caused by the lack of blinking due to focusing on screens too close to our face. This is an evolutionary phenomenon--close dangers cause extreme focus without blinking. Extreme focus on close items reduces our blinks. Our eye lids have glands in them that release oils on your eye with each blink. These oils help prevent the watery part of your tears from e…

How do you source lightbulbs? I have yet to find a reliable LED bulb that doesn't hum or flicker on a dimmer despite being advertised as "dimmable" . . .
Buy Lutron Diva dimmers and dimmable LED lamps (you probably call them ‘bulbs’), problem solved. For the Lutron Diva, you probably want this one: https://www.homedepot.com/p/Lutron-Diva-LED-Dimmer-Switch-fo... Philips sells dimmable LED lamps that work well. I sell electrical work for a living and this is what I use on my own home. If you want higher grade, commercial LED fixtures have built in drivers with heat sink…

How do you feel about LED headlights (assuming your car has them)? Great for safety or too bright and tiring?
Not OP but I think it can be either. Great for the safety of one driver who can see the road perfectly can be awful for the safety of another who is blinded. LED bulbs exacerbate an already existing problem caused by vehicle noses being too tall such that the headlight is exactly eye-height for other drivers. Sometimes they're poorly calibrated too, aiming too high. Many drivers also retrofit super bright LED lights…

Nature bathing is great. But it turns out that people in hospital beds facing windows recover faster when they face nature. And, in fact, it's not the nature at all! It can be fake and just as effective. In the end, basically, it's the green. Color therapy or chromotherapy is incorporating specific colors into your environment to evoke desired emotional states. It blows my mind how well this works, and that's why you…
How do you accomplish silver colored lighting?

I happened to find someone on a German forum (cars a VW) that had taken his overheads apart to do the same thing who posted a p/n or rather an industry size. I had never dealt with replacing SMD LEDs before but it seems there is an industry standard sizing that most adhere to. Just ordered a few in that size from Amazon and they worked. From what I remember most in that size were rated for similar voltages so seemed…
Desoldering / resoldering is not pain if you have proper tools to do it and know the correct technique. Trying to do it with an iron is making things very hard or even impossible (especially for smds with contacts below not at the sides). Using hot air rework station + preheater and low melt solder paste is the way to go - and it’s a piece of cake then. And you can do the whole board at once in a few minutes. I modde…
Do you by chance have any resources (videos or tutorials) to recommend that show how this is best done?
Is no lighting considered too little? I like to sit in the dark with nothing but a computer monitor for light. I have noticed this greatly reduces eye-strain and distractions, but perhaps that is just me.
You're an exception. For most people, sitting in the dark with only their monitor giving off light massively increases eye-strain.

I'm about to order a bunch of PCBs to substitute overhead lights on my car and some of my friends for something around 3000K and high CRI. Not only the color temperature is so cold, but usually the spectrum is terrible, and the quality of the light is awful. I just have to finish choosing the led driver :P
> some of my friends Lucky friends! Maybe repair shops could offer customized interior lighting as an aftermarket service.
Truth is, aftermarket lights for cars (typical AliExpress or Amazon stuff) always focus on brightness, but never on quality. It's usual for taxi drivers to have aftermarket lights in the vehicle, so you can find your money or credit card more easily, but the light quality is always terrible. :P

The bad LEDs can also be improved with yellow or amber film, which is more accessible to most people than desoldering. I found a German company that sent me a free sample of their amber film. As I recall their market was semiconductor manufacturing, but I can’t find them again. Amazon has a variety of films that should work.
Absolutely! That was my initial idea as well. Glad to know it’s an option
A sheet of Rosco 3408 takes you from about 5500K to 3800K so a much warmer colour. A small sheet which should be enough goes for about £7 https://shopwl.com/rosco-roscolux-3408-roscosun-1-2-cto/ you can probably find it cheaper just by searching Rosco 3408

I know it's a prototype, but in case you're interested in feature requests: if I have multiple webcams, it seems to just choose the first one without a way to select another.
