UV LED disinfection product prototype now done
Several Gulchers are going to be a Zoom call with me about this on Sunday, 4/25/21 at https://fit.zoom.us/j/4725447207 at 3 PM Eastern, 2 PM Central. All Gulchers are welcome to join.
Some of you know that I have been starting an ultraviolet LED disinfection product we call the VersaTILE to be sold through http://www.chem-freesolutions.com. See https://www.floridatechvirtualshowroo... first for more detail than the company web site has on our current status.
It uses LED's at six different wavelengths to ensure that proteins and DNA are disrupted for all types of pathogens and microorganisms. While you could use it at home, it really is not price competitive with some competitor's UV lamp technology (like PhoneSoap). I look it at step one in a multi-step process.
1) Build a disinfection product.
2) Put it into HVAC systems as a replacement for your UV lamp and eventually modify it so that it can be integrated into a self-disinfecting HVAC filter.
3) Put it in sterilizer boxes of various sizes, such as lots of items touched by students or customers for cleaning lots of items simultaneously.
4) Build a UV photography and photogrammetry system so that we can "visually" document that items are not sterile prior to disinfection and are afterwards.
5) Develop a process in conjunction with partners to reflect enough UV light such that sufficient light gets into the "nooks and crannies" of porous materials (like clothing).
There are a lot more applications for this than are currently on our web site. If interested, contact me at jbrenner@fit.edu.
The video linked in the URL is a senior design video by my Florida Tech students (also Chem-Free Solutions employees). Ultimately this came out of my Basics of Making class. If you have any future John Galts who want to be properly trained, I am kind of like Quentin Daniels (the Utah Institute of Technology professor in Atlas Shrugged). If interested in either my nanotechnology minor or chemical, biomedical, mechanical or aerospace engineering, contact me at jbrenner@fit.edu. I can address the electrical/computer engineers and computer science people, too, but not as well.

I think this looks like a great product.
I put the rated power through the LEDs, and the FR-4 started smoking within less than a minute. The vias had too much thermal resistance.
The good thing is Al PCBs are inexpensive now.
How could you document things that were not sterilized prior to disinfection?
Here's a quote from Wikipedia: "Sources where temperatures allow the bacteria to thrive include hot water tanks, cooling towers, and evaporative condensers of large air conditioning systems, such as those commonly found in hotels and large office buildings.[24] Though the first known outbreak was in Philadelphia, cases of legionellosis have occurred throughout the world.
Take care.
My point, in the past year+ I have not witnessed a sick person, anyone, including patients, with flu like symptoms out of 1000s of people per month...not even in the town where I live,
You'd think with a pretty high rate of supposed covid, I would have witnessed the disease.
