Heh, this would have been super helpful last summer as were nearing completion on the construction of our new home. We have an elliptical arch in our front portico that the carpenter was having trouble getting right...
Machine Learning Mastery (https://machinelearningmastery.com) provides code examples for many of the popular models. For me, seeing and writing code has been helpful in understanding how things work and makes it easier to put new developments in context.
Highly unlikely. 802.11x lives in the 2.4GHz and 5.8GHz ranges which are outside of the stated range of the tinySA mentioned in the article. Occasionally radios will work outside of the stated range with a bit of hacking, but 950MHz to 2.4GHz is pretty far. Software-defined radios (SDRs) like the HackRF One or BladeRF cover the 2.4GHz and 5.8GHz frequency ranges, but at a higher cost.
[edit: clarify the frequencies of the HackRF and BladeRF]
[edit2: Apparently the tinySA Ultra can cover the higher frequencies in certain configurations]
I recognize urine mycotoxin tests are potentially controversial, but these tests were very diagnostically significant for us and our mold journey. The mycotoxins that were off the charts in our tests matched the mold that was eventually found in our house (after multiple mold inspectors missed it).
This area is definitely more "gray" than implied by your comment. I have tremendous respect for Shoemaker, but there are some gaps in that paper that did not appear to address how our practitioner used those tests for us. Many of the studies mentioned in the meta-review focus on the presence or absence of mycotoxins not the measured amount. Also, our practitioner used the test "backwards" compared to procedure outlines in the review paper. Our practitioner used the test before we had any evidence that we lived in a water-damaged building, whereas the paper is specifically focused on determining cause of illness after exposure to a water-damaged building.
You need to find a functional health practitioner, and be willing to try many different practitioners. It took us several tries to find a practitioner who was willing to test for mold. If you aren't familiar, functional practitioners focus on the root cause of medical issues rather than just symptoms. We found success with a functional nurse practitioner, though they capped out and we have moved on.
You may be able to find ways to get the tests directly (not through a health practitioner) if that ends up being the path you need. They are not cheap and not typically covered by insurance, but we found being mysteriously ill was way more expensive in the long run than paying for tests. May your path to healing be a straight one!
I don't know of anything, but will buy if one exists. Closest thing that is out there are Indoor Air Quality (IAQ) detectors, some of the expensive ones detect particles as small as mold but the IAQ detectors can't tell you that it is mold, only that particulates of a certain size are present.
If you are concerned about mold being a cause, there are couple of urine tests for mycotoxins that were super helpful for us understanding the mysterious illness in our family.
This! One of the best solutions to prevent mold is to improve energy efficiency. There are an increasing number of grant programs and Housing improvement initiatives available, but still those improvements are out of reach for a lot of people. We live in the Southeast US which is incredibly humid and so many houses have issues.
I know, seems crazy from the outside looking in, but nothing was particularly outrageously priced (and we did get several estimates from all sorts of people). To be fair, it wasn't just the foundation. Because of the mold in the basement the rest of the house also became contaminated and needed to be remediated (and my family is now super sensitive). I will also note that this during COVID so prices were somewhat higher than they are now. Believe me we did not set out to tear down our house, but that ended up being the best way to address the issues with the old house.
> Afaik mold is only a big topic because of lawyers seeing a nice liability and the media a spooky story.
Unfortunately, mold is also a growing health concern for a sizable portion of the population. My family got severely ill from a moldy house, and it is taking us years to fully recover. The longer we have been aware the more and more folks we find are dealing with something similar.
The EPA Guide is a great start, but in our experience lacks some situational nuance that might increase its helpfulness. Each person reacts differently mold, some folks are just more sensitive than others. There are no federal standards for mold, either for allowable amounts in your home or guidelines for construction. So depending on your health response you may in fact need to go crazy tearing apart your house to hunt for mold.
After talking with ~30 different mold remediators, inspectors, remodeling contractors, etc. We got ~30 different responses for possible causes for mold in our our home. Ultimately, the cost to fix the true sources of mold in our home (due the sources being related to construction practices around the foundation) was equivalent to new construction. We ended up tearing down the moldy house. We're hoping to move into our new house late next spring!
