General Here is a prototype of my new USB powered high power LED lamp. This design is based on an Arduino Nano and one 1W Olson LED from Osram (LCW_CQ7P.EC). Next to that it has some cool features: -a 3D printed case -laser-cutted front glas -touch sensor I designed a […]

Measuring current with an Arduino or any other microcontroller is not as simple as measuring voltages directly with the Arduinos/microcontrollers ADC. In most cases a designer would use a current shunt amplifier/monitor. At first I started with the MAX9634F current shunt amplifier (CSA) in my design. The company Touchstone Semiconductor […]

Introduction During the last weeks I upgraded my solar-usb-charger system. Here you can find the original design: http://www.zipfelmaus.com/bau-dir-ein-apple-solar-ladegerat/ (german article). What the old design basically did was converting the 12V DC from the solar powered battery system to USB friendly 5V DC. New Features I added a couple of features: […]
