App note: Precision signal conditioning for high resolution industrial applications

App note from Analog Devices on robust precision signal conditioning. Link here (PDF)

Industrial measurement and control systems often need to interface to sensors while operating in noisy environments. Because sensors typically generate very small electrical signals, extracting their output from the noise can be challenging. Applying signal conditioning techniques, such as amplification and filtering, can aid in the extraction of the signal because these techniques increase the sensitivity of the system. The signal can then be scaled and shifted to take full advantage of high performance ADCs.

4pin hall sensor adapter board

Davide Gironi published a new build:

Hall Sensor are pretty common components. Most of the time one will find 3 pin Hall Sensor. But there are time that one can find a 4 pin hall sensor. Those kind of sensor is called dual-channel.

SI5351 signal generator test gadget

DuWayne published a new build:

I have been spending way too much time playing with the new 3D printer, so have to get back to some electronics.  Since the next CWTD.ORG episode is coming up, I decided to build another ‘Test Gadget’.  This time it is a Signal Generator based on the SI5351 clock generator.  I had purchased a couple Chinese versions of the Adafruit 5351 module when I was working on the ‘Sweeperino Jr. ‘ and wanted to see how  well they worked.

PopCom – Identify your COM ports

popcom

avishorp has written a small program that pops up a message whenever a serial port over USB device is plugged in, that is available on GitHub (code) and (installer)

PopCom is a COM port plug-in/plug-out notifier. Whenever a USB device that emulates a COM port is connected to the computer, a pop-up will be displayed, describing the device that has been plugged in and the COM number assigned to it. This pop-up helps determining the COM number assigned to each device, a number that is required for communicating with it.
