The Ohaus Scout SPX is a portable electronic balance that has a peripheral interface connector. This connection supports many different proprietary peripherals such as printers, displays, ethernet, Bluetooth, and so on. Each of these peripherals use this same 6-position mini DIN connector. This article will discuss how this interface works and how to enable the serial port capability for just a few dollars worth of materials. [Read More]

In this article we explore some high level concept of a series topology linear voltage regulator with some SPICE simulations and mathematical analysis. [Read More]

In this article we explore the fundamentals of the Decibel units and how to derive them using only power and resistance. We then provide an example of how these calculations appear in the time domain such as on an oscilloscope. [Read More]

The Fluke 376FC is a Bluetooth wireless AC/DC clamp meter which communicates over the BLE protocol using a proprietary mobile application interface. As of writing this article there is no known desktop application or API for interfacing to this unit. Therefore the goal is to produce a working interface which connects to the unit and allows a user to interface to the device remotely from a PC. [Read More]
