Thank you for the nice compliments, but I'm not an expert, I just know something, and listen to our technicians at work. I work for a hearing aid company, in our PCB manufacturing plant
Yes hydrophobic coating, the machine is quite expensive, so a now retired technican made the machine himself, (He is also a quite bright guy), anyway a similar machine can be bought from Europlasma https://www.europlasma.net/products.html
as I understand the gas (teflon I think is used as gas) is sprayed inside a vacuum chamber, and then the hearing aids with electronics are rotating (Like a slow tumblking washingmachine),
and then after a while not sure but about 20-25min the process is finished.
@Sebex said in Next generation dust sensor for MySensors:
@NeverDie could you share your Honeywell code, I have trouble getting it to work. An example will help me a lot t learn from!
I made a library for that, I'm updating it to autodetect some various PM, CO2, Formaldehyde UART sensors but I'll find the old version for Honeywell only tomorrow if you want. If I forget, harass me by MP
@bjacobse thanks, hope so too.
Just looked back into the thread, I posted a picture of my old workshop back in 2016, still the same tools around, just a smaller desk to work on.

There is actually two "products" that are sold.. Not complete with plastic box etc. And you have to solder a socket for the radio, and add the radio yourself, as well as do a bit of programming, but the SMD parts are already mounted. I think that this is the closest that you come to a pre-assembled unit these days.

@NeverDie said in Coronavirus (way, way, off topic):
I'm not sure how much the hospitals can actually do that makes a difference.
Specialist ICUs can save some of those who are develop viral pneumonia, the reality is that some will die but there is no telling which is which until they succumb. The dilemma is that once ICUs are overloaded the fatality rate climbs due to prioritisation, so the trick is to avoid overwhelming the facilities or accept a higher death rate than may otherwise be the case.
The easiest way to look at this much is as a flu outbreak, but with the added feature of 10 times the infectivity. For flu there are shots which can provide greater but not complete protection for the more prone, an annual mutation which the manufacturers refine on each cycle.
In the COVID case there is as yet no vaccine nor natural immunity, but crucially it is infectivity which is the danger as it presents a deluge of critical cases rather than spread over say many months.
Social distancing and isolation measures can slow the rapid spread, testing vigorously and isolating as in the Singapore and Korean etc models is another successful technique.
The rest is a political decision...
This post I thought entirely apt...
Quite a large number of inexpensive nRF51/nRF52832 watches which appear to have already been hacked, documented, and made available for others to now hack too: https://github.com/curtpw/nRF5x-device-reverse-engineering
