    To see the raw values in the serial monitor, you need to change this line of code in the ADXL362.cpp line 20

    const bool debugSerial = 0; 
    

    to

    const bool debugSerial = 1; 
    

    save ADXL362.cpp and recompile

    guys, this is NOT your typical 8Ω Ohm speaker! You can not just use a normal amplifier, you need their specific circuit and PCB.

    I think it’s a high voltage speaker. That big box is a transformer. The same concept of the electroluminescent circuit. They run at ~100V.

    The show floor is just a fraction of what is really CES. The real magic is in those very private show room and hotel suites around town. This is where you get the latest and newest stuff from big and small companies. It takes years to get contacts and invitation to those private demos. Even if you work for a big company, you can still get refuse to those demos!! Yep!

    I was once invited to a TI demo and the stuff was so new that they did not even have a dedicated webpage on their website!! “We just finish that thing 2 days ago!” Or this guys that after talking to him for 30 min that he finally get this prototype out of his pocket!

    You made a mistake @3:02 explaining the gear ratio. Listing again. You say for every 1 turn of the brass gear you get 5 turn of the aluminium gear. It’s the opposite. :)

    I think that one CPU is dedicated to one single task: Detect fire! The other CPU are for other non safety related task like there voice speech, the motion detection, the wireless communications, etc.

    That light sensor is probably use for there build in night light. They could also use that sensor to detect fire. For example, I remember reading something like this. There is different type of fires. For example, one of them can start in a couch and give out this thick smoke that is hard to be recognize by the standard smoke detector. To detect this type of fire, they can use a infrared/light sensor to see is the light beam is block by that specific smoke. Like a optocoupler. Imagine a IR LED at the end of a 1 inch straw. At the other end you have the receiver. It air tight. This becomes your “reference” measurement that is not affect by the smoke but only the light intensity. You then have other straw but with hole in the straw to let the smoke in. You use a other set of the same sensors. The smoke can now block the light beam and the system can compare that to the reference and trigger the alarm.
