@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
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.

Finally I am starting to do a little electronics again.. First thing is a prototype assembly of RASLE (Rpi Arcade Sound and Light Extension). It's a custom made arduino "coprocessor" for a raspberry pi, built into retropie arcade cabinets. It's a joint project with a couple of friends that are building arcade cabinets (I built mine a couple of years ago, I think that there is pictures earlier in this thread).
Features:
stereo 3W class-d amplifier
atmega328p
3 pwm channels for LED strips
a port for WS2812 type led strips
pwm channel for fan
output for a relay to control mains input for the box (let the rpi shutdown cleanly, before disconnecting power)
5 button inputs (shared between rpi and atmega)
@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.

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
