Microchip Technology has announced a free C++ compiler with unlimited code generation capabilities: MPLAB XC32++ Compiler (Free version), which supports all their 32-bit PIC32 microcontrollers. The compiler enables designers to develop and re-use C++ or mixed C/C++ projects in the MPLAB XC32 environment and makes all of Microchip’s C language extensions available.

The APDuino project is for those want to use an Arduino to run a custom sensor monitoring and automation projects (such as aquaponics, greenhouse, gardening DIY automation) without having to program any code. [ via ] Main features and characteristics: free, ready-to-flash software for Arduino Mega 2560 + W5100 EtherShield hardware combo supports a number of analog and digital Sensor and Control components in any custom (electronically valid) layout on the Arduino pins,  allowing building Your Own Automation System custom Rules for automation, allowing Sensor and Control data access, scheduler, timers and more,  allowing Your Custom Program to be created, without programming data logging on SD card and online sinks (cosm, thingspeak, apduino online),  allowing to Hook Your Automation System to the Internet-Of-Things and Web 2.0 services, eg.

BUT FIRST AN IMPORTANT NOTE: This project uses lethal voltages.  If you are not experienced in working with lethal voltages, read this project, but don’t build it. You only have one life, and AC power can take it from you very quickly, or leave you with terrible injuries. When working on high voltages, remember: • […]

Photo. This is the test circuit -the basic driver is only two transistors, two resistors, the circuit was evaluated using a white LED, but when it was time to button it up and archive it, I replaced the expensive white LED with a cheap green one. Othere LED Driver Circuits on this site: White LED […]

What it is The circuit allows a precision regulated drive current to be set to drive an LED, and in response to a TTL level signal, the LED is switched on and off with rise and fall times of less than 500 nanoseconds and less than 7% overshoot. This was designed for biological experiments to […]

Three inductor-free circuits that allow a white LED or UV LED to be driven from one (1.5 volt) or two flashlight cells (3 volts total) are described. The circuits on this page are: The two cell (3 volt) circuit four transistors. The simple single cell (1.5 volt) circuit requires six transistors, but it isn’t as […]

Download FreePC project file, gerber and png copper and silk-screen: 1wattledbuck.zip Introduction I have some 1 watt warm white LEDs left over from a project and the application for them was obvious: A better battery operated lamp for use when the power fails, which it does frequently, especially during the rainy season. And this one should […]

Overview The circuit shown in Figure 1 is capable of driving an LED array requiring up to several amps with a burst of flashes before coming on until power is removed. It is intended to be used as an auxiliary warning light driver. The initial burst of flashes is meant to enhance visual detection of […]

(Phys.org)—Research seeking to improve the features and functions of robots has made impressive gains with prototypes of robots that can help out in settings that range from assistive living, to hospital care, to inventory-taking retail stores. One area of robot technology receiving special attention at Honda is “robot audition.” How effectively can scientists fashion robots that can hear?
