UPDATE Oct 1, 2021: I have concluded launching all the roadtests I can prior to our platform migration. No new roadtests will be launch until mid to late November. Greetings. During the month of November, element14 is migrating to a ...
My RoadTest of the MAX77714 EVK just keeps getting more bizarre. Both of the push button switches on my EVK fail to operate. A few weeks ago I was briefly experimenting with the soft power button features and couldn't get it work. Turns out, it i...
I welcome you to this part of my RoadTest review of Bridgetek BT817 evaluation board. In this part I will briefly describe one of my experiments which I have done for gaining experiences with BT817 chip and evaluation board. In this blog post I will ...

Introduction The modulation capability of the instrument virtually turns the instrument into a voltage amplifier with gains of 0.5, 1 or 2. As previously shown in the regulation tests, during modulation the instrument samples the input signal at...
Introduction To explore the regulation capabilities of the SMU I performed a few tests to see how it behaved in voltage priority mode (VPM), current priority mode (CPM), and in the (voltage) modulation mode. Let's briefly explain what all th...
I'm getting ready to launch a roadtest on a 70 W Single-Phase Inverter Using BridgeSwitch for Fan Application. I was sent the board, but I wanted to send a motor with the inverter board. I'd like to get some help in selected a compatible motor....
The Aim-TTi QPX750SP is not a typical bench power supply. A typical bench power supply may have two or three output channels capable of delivering 0 to about 30 VDC at up to say 3 A. For example, my Keysight E36313A is a typical bench sup...
I am thrilled to have been selected to roadtest the BT817 chip and while it has only been 4 days since I received it, I wanted to share some information early on as it may help other people working with the evaluation board.Once I have worked ...
Solar Cell Characterization (Workflow Comparison)Solar or photovoltaic cells are devices that convert light energy into electric energy through the photovoltaic effect. Optimizing power conversion from solar cells is not trivial because of the shape ...
Introduction A Peltier device is a solid-state heat pump that transfers heat from one side to the other. The heat transfer simultaneously reduces the temperature at one side of the device and increases it at the other side, generating in this wa...
Introduction DC-DC converters are devices that convert a source at one DC voltage into another. They can be classified in many ways, such as between linear and switching, step-up and step-down, based on their topology, and so on.Depending on the...
Introduction Properly optimizing energy consumption of battery powered microcontrollers is fundamental to extend the battery life. Questions like when it is better to keep the device idling and when to enter light- or deep-sleep cannot be answer...

The AIM-TTI QPX750SP is a powerful bench power supply, capable of providing a maximum of 750W DC power within a wide voltage range of 0-80 V. It is a profes...
Greetings! I wanted to share with you a fun opportunity that any roadtester who is also a maker and project builder may enjoy. Our agency has started a series called "Movers and Shakers in the Maker Space." The series is broadcasted o...
This page is a collection of snippets for the RoadTest of the MPM54304 <link to final review> In this road test I aim to answer the following 2 questions:(1) How is the MPM54304 programed the first time?(2) How well do the software tools p...
This is the fourth blog post (and the last one) in a series that has covered my on-going roadtesting work of the Rohde & Schwarz NGU401 SMU instrument. I had to post this update as a separate blog because when I tried to append it to the pr...
