Solved an interesting problem last week using an Arduino UNO.  We needed to sync two IDS Particle Image Velocimetry (PIV) cameras using a hardware trigger. https://en.wikipedia.org/wiki/Particle_image_velocimetry The two cameras were different models and had different connectors.  There are many ways to trigger the system depending on what action you want to capture. https://en.ids-imaging.com/tl_files/downloads/techtip/TechTip_GEV_TriggerCtl_EN.pdf   I could have just conne ...
  Single-Ended Transmission Single-ended signaling is a simple and common way of transmitting electrical signals from a sender to a receiver. The signal is ground referenced (0 Volt) and one conductor (wire) carries the signal and one conductor carries the common reference potential. The current associated with the signal travels from sender to receiver and returns to the power supply through the shared ground connection. If multiple signals are transmitted, the carrier requires one wire ...

Switching power supplies are known for high efficiency. An adjustable voltage/current supply is an interesting tool, which can be used in many applications such as a Lithium-ion/Lead-acid/NiCD-NiMH battery charger or a standalone power supply. In this article, we will learn to build a variable step-down buck converter using the popular LM2576-Adj chip.                           &# ...
On returning home one day recently I was excited to discover a bag from Element14. Element14 boxes and bags are always exciting as they are always unexpected and full of interesting things I don't have. After looking at other comments I have guessed that this bag of gifts is for my comments on the 10 Year Challenge - which I had found interesting as 10 year ago I was still hammering away at my career and trying to open up the potential of my student's minds. Now I'm nearly two years retired and ...

This guide shows you how to use the MATRIX Creator or MATRIX Voice with ODAS, a library for direction of arrival, tracking, and much more.     What is ODAS? ODAS stands for Open embeddeD Audition System. This is a library dedicated to perform sound source localization, tracking, separation and post-filtering. ODAS is coded entirely in C, for more portability, and is optimized to run easily on low-cost embedded hardware. ODAS is free and open source. Find more at: https://github.com/ ...
