Re: AS3935 Lightning Detector unable to initialize

@TS-Chris and @TS-John, I sent my boards back to you for checking. One thing I noticed one my last tries before I sent them back is that I think the library from PWFusion_AS3935_I2C seemed to communicate with the device. It makes me think there is some timing issue with the I2C library being used. W...

I tried the "I2C Scanner" sketch (from both the SFE GitHub and ArduinoCC) and got the device's I2C recognized. Result follows: I2C Scanner Scanning... I2C device found at address 0x03 ! done I then tried the AS3935 SFE sketch again with the same results. See below: AS3935 Franklin Lightning Detector...

I have an AS3935 Lightning Detector board (SPX-15057) connected to the BlackBoard C (SPX-15098) but it doesn't go past the "Lightning Detector did not start up, freezing!" prompt. I have the same Blackboard talking to a QWIIC OpenLog and that communication seems to be fine so I don't think the issue...

Re: ESP8266 Thing - Dev Board

The technical info for the ESP8266 suggests the lone ADC input is rated at 0-3.3V. You may want to contact SFE directly as to why they recommend +1V max. Scratch that - their latest datasheet says " The input voltage range is 0 to 1.0V when TOUT is connected to external circuit ". So you are lookin...

Re: HX711 and 50kg load cells - unstable values

Not sure why you think the SFE guide indicated to connect black wire to white one. The following seems pretty explicit: The four wires coming out from the wheatstone bridge on the load cell are usually: •Excitation+ (E+) or VCC is red •Excitation- (E-) or ground is black. •Output+ (O+), Signal+ (S+)...

Alexa Spot and "Drop-In" function?

If you want to go DIY route, ultrasonic (HC-SR04) with ESP Thing. If you want easier quick connect stuff, maybe look into QWIIC (e.g. HC-SR04 and ESP32).

+1 to what was said on eevblog The comment about gluing two 2-sided PBs together is circa 1970. The 3rd layer is for sure "light" and could easily take copper pours. Since the 4th layer looks mostly to be control lines I would add ground pours on layer 3 without much hesitation (since the microstrip...

The code on the electro-tech tutorial invokes averaging from the "HX711.h" driver, to provide more stable readings, which could limit the update rate. If you load the code from the electro-tech tutorial as-is; does the OpenScale work? The averaging function is "mentioned" on SFE's Hookup Guide: "Ave...

Via ground fencing -> a cheaper version to edge plating. It could be to prevent unwanted energy from radiating out of the board edges. Or it could be to provide ground connection for some sort of edge connector (e.g. PCI slot mount).

It should work. I had it working from +5V to +28V (I was using very low speed .. only because I was using it to switch a high voltage on/off with an Arduino).
