@benbrown depends on your workflow.

You can even use a #RaspberryPi with the #HDMI2CSI adapter board.

  • OFC you propably need a splitter so the sending device gets a proper #EDID and doesn't negotiate the wron resolution.

Don't forget that cracking #HDCP is a legal no-no, but there's no way for anyone to find out...

@Laberpferd @cmdrmoto Which is why people need to really read the SDS before buying, installing and using.

  • After all, the non-skin-penetrating variant also doesn't work for desinfection of entire rooms!

I only had to deal with #UVC lampts that explicitly were not at that window because they were setup as a "#biocide filter" in a water system to kill all fungi, bacteria, viruses and small single/multi-cell organisms that pass through the tube segment they were installed in.

  • In fact, almost all #UV-C Lamps I saw on sale were with a RF remote so they don't get flicked on with a lightswitch, but specifically from outside the room without any occupants in it to prevent exposure (like an X-ray machine at a doctors' office)!

Precise wavelenght filtering is extremely expensive and bulky so unless it's very specific unit designed for that I'd NEVER assume it's safe for any living being whilst in use!

@cmdrmoto I'd still don't consider #UVC harmless for humans.

  • It works well for surface desinfections and to sterilize objects that can't be chemically or heat/cold-treated.

  • #SafetyDatasheets say it's unsafe for humans in the vicinity.

Regardless, her affordable & effective #PPE designs are really awesome, combining form, function and ingenuity whilst allowing the use of cheap COTS parts and using #3Dprinting sparingly to get like mountings and other parts done that most people can't fabricate cheaply due to lack of spechalized tooling...

Whatever happened to studies around using far #uvc light against viruses bound in aerosols?

See e.g.here nature.com/articles/s41598-020

NatureFar-UVC light (222 nm) efficiently and safely inactivates airborne human coronaviruses - Scientific ReportsA direct approach to limit airborne viral transmissions is to inactivate them within a short time of their production. Germicidal ultraviolet light, typically at 254 nm, is effective in this context but, used directly, can be a health hazard to skin and eyes. By contrast, far-UVC light (207–222 nm) efficiently kills pathogens potentially without harm to exposed human tissues. We previously demonstrated that 222-nm far-UVC light efficiently kills airborne influenza virus and we extend those studies to explore far-UVC efficacy against airborne human coronaviruses alpha HCoV-229E and beta HCoV-OC43. Low doses of 1.7 and 1.2 mJ/cm2 inactivated 99.9% of aerosolized coronavirus 229E and OC43, respectively. As all human coronaviruses have similar genomic sizes, far-UVC light would be expected to show similar inactivation efficiency against other human coronaviruses including SARS-CoV-2. Based on the beta-HCoV-OC43 results, continuous far-UVC exposure in occupied public locations at the current regulatory exposure limit (~3 mJ/cm2/hour) would result in ~90% viral inactivation in ~8 minutes, 95% in ~11 minutes, 99% in ~16 minutes and 99.9% inactivation in ~25 minutes. Thus while staying within current regulatory dose limits, low-dose-rate far-UVC exposure can potentially safely provide a major reduction in the ambient level of airborne coronaviruses in occupied public locations.

In educational institutions:
* #HEPA cleaners and #UVC lights are effective, especially when properly sized and positioned relative to the infected and susceptible persons.
* HEPA cleaners could reduce #aerosol particle load by 85-95% within less than 20 minutes of operation.
* Implementing proper #ventilation and air cleaning strategies can create safer environments for students and staff, reducing absenteeism and promoting better learning conditions.
