In this project, we are building a programmable single/multi cell lithium battery charger shield for Arduino. The shield provides LCD and button interface which let the user set the battery cut-off voltage from 2V to 10V and charge current from 50mA to 1.1A. The charger also provides the ability to monitor the battery status before

All parts were developed separately. This allowed adjustments in the assembly as well as smaller changes in case the design of one or other part become required. Focus on low cost and use of materials easily accessible in the local market. For more detail: Homemade Plotter (CNC Machine)

Product Description This is a light sensor that I’ve been waiting for, for a long time. If you use photo cells or phototransistors, or other light sensors such as the useful TAOS TSL series, you know that every one leaves something to be desired. In robotics for example, sensors either tend to saturate in dark

Professionals, school laboratories and amateurs can now gain this new, extra affordable digital MSO oscilloscope in a limited offer. Probably you may have noticed, that company Hameg became a member of Rohde&Schwarz group and new oscilloscopes already carry only an R&S logo. However the name of series HMO remains, which represents for several years
Its hard to resist to R&S HMO1002 oscilloscope for 610 Euro Continue Reading
Who is the winner of umodule demoboard from Linear technology? In addition to getting to know the winner, you can also watch the video record from webinar… Linear Technology’s family of DC/DC Module products simplifies your analog design. By integrating the DC/DC controller, power switches, magnetic, and a modest amount of capacitance, uModules power products
When we first released our 3D printer, we tried to use some parts that were already available and tested, in full respect of the open source philosophy. In particular, we decided to use the electronic card Sanguinololu. The “open” firmware we chose, the Marlin firmware by Erik van der Zalm, solved the biggest part of
A new board for the 3Drag: there’s more than Sanguinololu using arduino Continue Reading
