This ible is for the building of my small, almost matchbox size, arduino compatable board. As seen in this ible.. http://www.instructables.com/id/Pocket-Ardiuno-kit/ I experemented with the one in this ible to see how it can be impreoved, but the consept is the same and so is the build to a degree. Origonally made as a pocket […]

A synchronous PWM controller for negative-to-negative or negative-to-positive DC/DC conversion, the LT8709 from Linear Technology is easily configured for buck, boost, buck-boost, and inverting topologies to accommodate a wide range of power-supply designs. The device’s synchronous operation means that the output diode is replaced with a high-efficiency P-channel MOSFET, increasing efficiency and allowing for higher […]

Hello, I have plans to build myself a solar powered wireless Geiger counter using a RH Electronics Arduino IDE Geiger counter connected via a serial connection through a logic level converter to a 3.3V ATmega328P-AU Pro MCU with an ESP8266 serial WiFi tranceiver to send the readings from the Geiger counter to radmon.org.I intend to […]

There is a new addition to the popular WS2812 family of RGB LEDs with integrated controller: A 8mm through hole version. Right now they seem to be in pilot production stage. The only place that has them is Soldering Sunday where they are called PixelBits. My understanding is that they will also be available at […]

As mentioned on the Contents page, two different hardware platforms have been successfully used to support Mk2 PV Routers. [Update at 7/3/14:  Since writing this article, I have developed a new hardware platform which has been specifically designed  for this product.  The main board has an integral power supply and RF module, and there is […]

We are eager to announce the launch of the official Arduino Starter Kit! We have been working hard together in developing a complete selection of 15 projects that will let you become a true arduino tinkerer! But that’s more: read through for the whole components and projects list We are aware this kit will let a […]

The idea for this project came to me on the way to the trash. I was tasked with throwing away a box that has just been emptied of its original Ferrero Rocher sweetness content by my dear wife. This was shortly after the Valentine’s Day. So, I got to spend 10 seconds alone with this […]

In this tutorial you will learn how to communicate with a computer using a MAX3323 single channel RS-232 driver/receiver and a software serial connection on the Arduino. A general purpose software serial tutorial can be found here. Materials needed: Computer with a terminal program installed (ie. HyperTerminal or RealTerm on the PC, Zterm on Mac) […]

I just brought a new lamp and after a week, I’m tired of looking at it randomly change colours between red, blue, green. What can you expect from a cheap lamp brought at 5$ . Looking at the lamp I realized that I could make a Gmail lamp, that shines green every time I got […]

KORG INC and Noritake Co., Limited are proud to announce the successful development of the ground breaking technology, Nutube, a new miniaturized and high performance tube. In cooperation with Noritake Itron Corporation, KORG INC. has developed the Nutube to offer incredible reliability and efficiency while still generating the same rich harmonics which vacuum tubes are […]
