To our customers, The past year has been challenging. In addition to continued uncertainty due to SARS-CoV-2, we are in the middle of a historic semiconductor shortage, which started becoming critical in early 2021. The shortage shows little signs of...
Software Architecture and State
In this blog post, we examine our recent work with the Joulescope User Interface (UI). We step back from current and voltage measurements to discuss our challenges and how we improved the software architecture for future success. Software architecture is how software...

Electrical current is the flow of electric charge from positive voltage to negative voltage. We now know that electrons move through conductors from negative voltages to positive voltage. We had a 50⁄50 chance of guessing “right”, so, yeah. Electrical current is the...
This video demonstrates the Joulescope User Interface running on a Windows® 10 PC. The Joulescope User Interface software is open-source. You can find the source code on github: pyjoulescope_ui pyjoulescope The target is the Arduino Pro Mini 3.3V (SparkFun, Adafruit)...
This video introduces Joulescope, a new low-cost energy analyzer, which measures current and voltage, then computes power and energy. The video includes two demos. The first demo is a static measurement. The second demo uses an Arduino Pro Mini to...
Challenges measuring energy consumption with a multimeter
Multimeters are a necessary tool for developing electronic devices. In this article, we will explore the challenges of using a multimeter to estimate the energy consumption of an example device: a microcontroller-based wireless sensor. Current measurement is performed using an...
