Last weekend we visited the Ars Electronica Museum in Linz, Austria. It’s not a museum showing things that were common centuries or decades ago. They show present and future technologies and try to raise awarenes for possible problems and opportunities. Two parts of the exhibition were particullary interessting for me: […]

A visit of the Ars Electronica Museum, Linz – Austria

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 […]

Arduino: measuring current: use a current shunt monitor

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: […]

Upgrade: Solar-USB-Charger

I have a couple of new pcbs in development. Firstly there is the lightning-sensor-shield. It uses a AS3935 sensor from AMS to detect lightning. I’m pretty excited to get this one running. Then we have a power LED nano shield. You plug it onto an Arduino Nano. It’s possible to […]
