Re: Will I have severe water damage?

If this sort of thing happens your best bet is powering everything off immediately. Dry your electronic device as quickly as possible with paper towels and place it on a radiator to dry out, or put it in a plastic bag with silica gel packets or you can use rice in an emergency. On no account should ...

Re: Raspberry pi BBC news story

I must add uv-c LEDs at 275nm emit dangerous radiation, but you should be okay if you have wear welding gear, especially the face visor or you are operating them in a light tight container with the lid on. You can test a container for light containment by temporarily using white LEDs instead.

Re: Raspberry pi BBC news story

You shouldn't get ozone from LEDs at 275nm. The older glass discharge tubes for hotel room disinfection give off a spread spectrum of UV rays which contains UV radiation in the shorter wave lengths, which will create ozone gas. I bought 50 uvc leds off Alibaba for £80. As soon as I paid for them the...

Re: Raspberry pi BBC news story

Nope it's a simpler idea than than that. My idea is you just need a spiral air passage way containing between 20 to 50 275nm LEDs attached to a face mask in a light tight container. However a laser diode would be better option of the same length wavelength in a straight tube, due to higher energy de...

Re: Flu Hood For Hospital Beds

I kind of regret this topic is super off topic as well.
I know about negative pressure rooms. The problem is there are not going to be enough of them.
I also know about the stringent safety rules in hospitals.
I will look round for a more suitable forum or make one.
