Jakoblog Das Weblog von Jakob Voß. Die Maker-Community Knowable.org. 2 November 2012 um 09:08. Über die Berichterstattung zur Retune-Konferenz. Bin ich auf das Berliner Startup knowable.org. Gestoßen, dessen Gründer Simon Höher auf der Retune einen Vortrag. Gehalten hat. Retune ist eine Platform zum Austausch von Bau- und Bastelanleitungen, also so ähnlich wie Instructables. Und ähnliche Seiten. Knowable.org vergleicht sich. 1 Die auf Knowable veröffentlichten Projekte sind unter CC-BY-SA lizensiert.

http://bildr.org/2011/01/hmc6352
Finding your way with the HMC6352 Arduino. Tuesday, January 11. Ever look into getting yourself a digital compass. But stopped because of this or that? Or maybe you bought one of the HMC6352 modules. Because it said it was drop dead simple, but never got around to getting it to work. What ever the reason, I want to let you know, the HMC6352 is very simple, more so than an analog. One in many ways. But simple does not mean easy, it is after all an I2C. A in hex, A command is:. The Get Data command. The he...

One Wire Digital Temperature. DS18B20 Arduino. Friday, July 8. I know… you are probably thinking “Another Thermometer! How many do you need to cover? 8221; – Well… All of them. But really, they all have something different to offer. For instance this guy, the DS18B20. Has a unique serial-number sent with it’s data, so if you needed to have 50 of these on one bus, you could and still know exactly where the reading came from. And… It’s digital. Bus it uses to transmit the date is just one wire. And didn...

bildr » Sensing Humidity With The HIH-4030 + Arduino
http://bildr.org/2012/11/hih4030-arduino
Sensing Humidity With The HIH-4030 Arduino. Sunday, November 25. Humidity is weird. Even though we experience it all the time, it’s not something we can normally guess with any accuracy. This is probably because when we talk about humidity, we are talking about relative humidity. Relative humidity is relative to temperature, so a change in temperature alone is enough to change the relative humidity. This makes guessing the humidity extremely hard. Suggested Thermometers (with article):. To properly cacul...

Triple Axis Magnetometer HMC5883L Arduino. Monday, February 27. One of the first articles we did was on the hmc6352 digital compass. Well this is his older brother (or younger but smarter). I really don’t know what to say about the HMC5883L other than it is a three axis magnetometer, so it is capable of sensing in 3 directions. Something I found interesting and obvious once I thought about it, is that all compasses point to magnetic north. And not true north. You can look up your Magnetic declination here.

http://bildr.org/2011/05/mpr121_arduino
Sensing Capacitive Touch – MPR121 Arduino. Tuesday, May 31. Every now and then you get sick of the typical push buttons and you want something cooler. And what is cooler than touch sensitive things? Remember that old lamp in your Grandma’s that changed brightness just by touching the base? Yeah, that’s right… We are talking THAT cool! The MPR121 capitative touch sensor. Gives you 12 of such inputs that we can use with our Arduino, and you can get it in several forms from SparkFun. Is a 2-wire serial.

bildr » Are we getting close? Proximity Sensors + Arduino
http://bildr.org/2011/03/various-proximity-sensors-arduino
Are we getting close? Tuesday, March 8. All 3 sensors will be outputting an analog. That we will be reading with our Arduino. The typical Arduino has 6 “Analog In” pins. Located on them. These analog inputs act just like a voltage meter, sensing the voltage on that pin, and are actually 10 bit. Analog to digital converters. For more information on ADCs. This resolution limitation of the Arduino’s ADCs are a large part of the reason that analog. Sensors are often inferior to their digital. Output. Con...
