ECG: measure your heartbeat
Its pretty interesting to measure ones heart beat. A lot of fancy analog circuitry is needed for this. But fortunately there is a Arduino shield for this: the SHIELD-EKG-EMG from Olimex. [caption id="attachment_3242" align="alignnone" width="606"] ECG wiring[/caption] Hardware: - EKG/EMG shield (price: ~24€), Manual: [Link] -SHIELD-EKG-EMG-PA - passive electrode for SHIELD-EKG-EMG shield (price: ~12€) -Olimexino-328 ...

Measuring current: use a current shunt monitor
Measuring current with a microcontroller is not as simple as measuring voltages directly with the microcontrollers ADC. In most cases a designer would use a current shunt monitor. At first I started with the MAX9634F CSA in the design. The distributor FutureElectronic offers a pin and specification equivalent alternative from Touchstone ...

Upgrade: Solar-USB-Charger
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: -OLED-I2C-display (from wide.hk) -Arduino Nano -current sense ...

new pcbs: lightning shield, current shunt monitor, …
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 dim ...

Arduino: OLED I2C display and Lightning Shield
Currently I'm working on two Arduino projects, both will upgrade my weather station. OLED I2C display The OLED is connected to an Arduino Nano via I2C and it measures the current voltage of the solar powered batteries. The OLED display is available at wide.hk for 16$. Lightning Shield The other project is pretty ...

Arduino quickie: add a watch-dog to your application
This is a small hint, how to add a watch-dog to your Arduino application. I'm using the Arduino in 24/7 mode in my weather station. For unknow reason the software sends no data to our host system, it got stucked somewhere. So I added the watch-dog to prevent this. Adding this ...

Arduino: Weather-Shield – schematics, layout, code, … – everything you need
I've been working quite a while on my weather station project. Since the first version of the hardware had some bugs, I redesigned the electronics from scratch and created a weather shield for the Arduino. So here it is: Overview: The shield has several sensors: - barometric pressure sensor - BMP085, from Bosch, ...

Arduino: neues vom Weather-Shield
Eigentlich könnte alles so einfach sein, aber wenns so einfach wäre, könnte es ja jeder, z.B. Elektronik entwickeln. ;) So zieht sich die Fertigstellung der Hardware des Weather-Shield für die Arduino-Plattform schon wieder ein paar Monate hin. Der Schuldige ist auch ausgemacht, es ist der Barometrische Luftdrucksensor BMP085 von Bosch. (Der ...

Mit dem Z-Acceleration-Shield auf hoher See
Anfang Juni waren wir auf hoher See unterwegs mit dem Kreuzfahrtschiff "Adventure of the Seas". Wir berichteten hierzu bereits auf geekcruise.de. Das Zipfelmaus-Team hatte natürlich nicht nur Sonnencreme im Gepäck, sondern auch ein paar Technik-Gadgets mit dabei. Neben einer kleinen Fotoausrüstung und einen Garmin GPS zum Aufzeichnen der Route hatten wir ...

Bau dir ein Apple-Solar-Ladegerät
Update 19.09.12: Unter http://www.zipfelmaus.com/blog/upgrade-solar-usb-charger/ habe ich die Erweiterung um ein OLED-Display und eine Strom-/Spannungsmessung mit einem Arduino Nano beschrieben. Idee Warum nicht seine eigenen Apple-Geräte mit Solar-Strom laden, wenn man über eine entsprechend Leistungsfähige Anlage verfügt? Einleitung Wichtiger Hinweis: Bitte beachte, der Einsatz eines selbstgebauten Netzteils kann Auswirkungen auf die Garantie des Herstellers machen. Ein ...

Arduino Pan&Tilt-System
On this page we present the Arduino Pan&Tilt-System. An Arduino controlls a Canon Ixus Camera and two servos of the camera pan&tilt system from Lynxmotion. We also designed a aluminium plate where all parts are mounted on. You can use this design to make ultra-mega- or even giga-pixel images or make ...
