Here is another guide from David Johnson-Davies @ technoblogy.com explaining how to program an ATmega328 on a breadboard using the Arduino IDE. The guide is focused on how to use the internal clock of the microcontroller and how to achieve this using the Arduino environment. By default...

Project provides 1.2 to 20V DC output with current limiter adjustable to 0-5A. I have tested the circuit with 250mA output without a heat sink. Project is capable to drive 3A continues load and 5A peak, large size heat sink required for full load. The tiny power supply based on low cost...

It all started a few years ago with Component Organizer, than BOMER and it's now called BOMIST. The software runs locally, so no server nor setup required and you can have as many databases as you want (just run as many instances of BOMIST as you want). Additionally, it is integrated...

David Johnson-Davies @ technoblogy.com build a breadboard friendly power supply to power your Arduino or other low power electronics. The power supply is able to deliver 0V to 5.5V at up to 0.5A and it's powered from two Li-Ion rechargeable batteries. The output can be adjusted using...

72 channels Serial (SPI) to parallel driver board has been designed for various applications. This project can be used as multi Solenoid driver, large size 7 segment display driver, bar graph driver, and LED driver. The project works with 5V logic levels. Output load supply 12V-48V DC...

With LCR-, ESR-meter, AC/DC Voltage/Current meter, Oscilloscope and Signal Generator this device covers all needs for low frequency PCB debugging. LCR-Reader-MP recently released by Siborg Systems Inc. which joins the LCR-Reader family of handheld LCR- and ESR-meters, offers users...

FastCAP Systems has launched its latest product – a board mountable chip ultracapacitor. This new product offering is the first low ESR, thin-profile, reflowable ultracapacitor on the market and is now available for purchase in FastCAP’s online store. This chip ultracap has the...

Sinovoip had announced its new board Banana Pi M2 Magic. At first, it is an ARM SoC development board that features a high computing performance in a 51mm square portable design. In addition to onboard WiFi and Bluetooth, M2 Magic offers 8GB eMMc storage and DDR3 SDRAM of 512 MB. There...
