SVS Embedded has built a nice proof of concept. It has a ton of peripherals hanging off the Raspberry PI. The system uses a vibration sensor and accelerometer to determine if an car accident has occurred. An LCD display reads out the information for the user. GPS captures the location of the incident and transmits it to a cell phone using a SMS transmission using the cellular radio.
SomethingUnreal has built a simple system to demonstrate how a PID Motor Speed Controller works. The system is spinning a piece of cardboard on a toy DC motor. The motor is powered by an H Bridge. An optical sensor provides feedback to the system so that it can see the actual speed and adjust the H Bridge accordingly. The software running on the PC is very nice as it allows
FPS Weapons has built this DIY EMP Generator. It uses some off the shelf components to generate some large EMP pulses with the push of a button. The device runs off a rechargeable lithium ion battery, a high voltage converter goes through a spark gap and then through a coil. The coil was made using some varnished wire. Hot glue was used liberally to keep everything in place. Use this device with
Mike Harrison built this interesting LED mall display. For single install design it is quite involved, the system is very flexible allowing for it to be easily programmed and interfaced to. The use of RGB and a white LED is an interesting way to ensure you get a pure white light with no color mixing needed.
Joe Menard had many needs for IOT devices in his life, he is an electrical engineer but needed fill in lots of programming knowledge to get his ideas to come to life. He started at a very low level even building a switch mode power supply, with 170 volts on board trace spacing was something that was very important. For the enclosures he didn’t simply buy something and stuff his
If you are looking for new ways of getting your Arduino gear to become productive why not try programming it as a state machine. Via: Electronics Labs “Did you ever program an Arduino? Have you ever been worried about complex control flows written in pure C? Maybe you have already heard of statecharts and state machines? YAKINDU Statechart Tools for Arduino is based on Eclipse, YAKINDU Statechart Tools, and
