A photoresistor can sense the subtle changes in light intensity caused by your blood to detect your heartbeat!
Simple data logger that stores electrical data (voltage, current, power, energy, etc.) in an SD card, with timestamp for later analysis.
The ability to process, manipulate and otherwise work with audio signals is a key feature of DSP in FPGA. Here's a look at how we do this!
Exploring the signals behind Arduino's Servo library, and characterizing a servo's response to pulse width.
How to build an humidity and temperature meter with time display from an old voltage meter casing.
I wasn't happy with the way the square waves sound, so I explored using other methods of generating sound waves with Arduino.
It's a Morse code receiver base on processing the light signals.
This getting started guide teaches you how to program Python on Digilent Arty Z7-20, the Xilinx Zynq Z7020 SoC platform.
A discussion about digital sound synthesis.
Monitoring and controlling my UPS from Cayenne with SparkFun ESP8266 Thing Dev Board.
Learn about photoresistors and the process of characterizing their response to light intensity.
Imagine 120V, coming out of 2 controllable outlets. All coming from a (wireless) box with WiFi. Yeah, that's what we're talking about.
I have revamped the control system of this 20-year-old 5DOF articulated robotic arm with TP controls and programming interface integrated.
A robot capable of motion in response to our gestures.
Find the location of a device, using multiple DWM1000-ESP8266 pairs, and an FPGA.
The HDrive is an easy to use IoT-enabled servo drive, both for the inexperienced and for professionals.
Project with a social purpose to aid the visually impaired. The glasses can detect obstacles up to 4m away and are readjustable.
Part one of a project that will demonstrate the building of an FPGA/SoC-based hexapod robot.
Ever care about the place you may spend one third of a day? enVMon captures noise level, air quality, UV level, temperature and humidity.
A simple and cheap three wheeled time waster for almost any skill level. Basic stats are Arduino Mini Pro, Sonic distance, and a Gyro.
How to make a homemade electrocardiograph (ECG).
I built the right and left mouse buttons with wall switches.
Using the Arm DesignStart FPGA Cortex-M3 to control a simple wheeled robot. Also known as getting started with DesignStart FPGA & Cortex-M3.
Remember the days when you would sit listening to WWV time signals on your shortwave radio (tick, tick, tick…At the tone, the time will be…)
