When recording from multiple devices simultaneously (e.g., Vicon motion capture, EEG, eye tracking), each device has its own clock. By feeding the same pseudo-random sync signal into all devices, you ...
In this video, I'm exploring the use of Mini PIR Sensors with ESP32 with both Arduino-based projects as well as making a movement sensor for Home Assistant by using ESPHome. The sensor is quite ...
In this video I'm building an Arduino Heart Rate Monitor that is housed in a toy handle in the style of the Star Trek Tricoder. The device uses the PulseSensor with an Arduino Pro Mini and an OLED ...
For spectrum analyzers lacking a tracking generator, this broadband RF noise source is affordable and will help measure a ...
There have been many questions about what direction Arduino would take after being bought by Qualcomm. Now it would seem that we’re getting a clearer picture. Perhaps unsurprisingly the answer appears ...
Atek Midas, a Turkish company, has launched DSG-22.6 GHz, a high-performance, open-source RF signal generator designed to provide professional-grade ...
Who among us does not have a plethora of mains-powered devices on their workbench, and a consequent mess of power strips to run them all? [Jeroen Brinkman] made his more controllable with a ...
Abstract: An experiment in transmitting speech by Pulse Code Modulation, or PCM, is described in this paper. Each sample amplitude of a pulse amplitude modulation or PAM signal is transmitted by a ...
