A couple days back, I wrote about ‘The $3 Arduino‘, how to leave the Arduino board behind and program an ATmega168 Micro-Controller directly, still using the Arduino IDE but with the AVRMSPII programmer. Of course, the ATmega168 isn’t the only MC available for something like that. In fact, I have quite a few 8-bit AVR […]

The $3 Arduino

Buying and using an official Arduino Board like the standard Arduino Uno is the perfect way to get started with the Arduino language, common electronic components, or your own embedded prototyping project. However, once you have mastered the initial challenges and have built some projects, the Arduino Board can get in the way. For instance, […]
Streaming Your Webcam w/ Raspberry Pi

[Last updated on Feb. 2. 2013 for (2012-12-16-wheezy-raspbian) Kernel Version 3.2.27+] Three years ago, we bought two small Webcams and since we wanted to use them on Linux and OS X, we went with the UVC and Mac compatible Creative LIVE! CAM Video IM Ultra. This Webcam (Model VF0415) has a high-resolution sensor that lets […]
Accessing Raspberry Pi via Serial

Using a serial connection to connect to a Raspbery Pi has many advantages. The boot process (Kernel boot messages go to the UART at 115,200 bit/s) can be monitored, without the need to hookup an HDMI-Monitor. Once booted, you can of course login through a serial terminal as well, i.e. the serial connection allows logging-in […]
Tiny WiFi Adapter for Raspberry Pi

[Updated on Feb. 2. 2013 for (2012-12-16-wheezy-raspbian) Kernel Version 3.2.27+] The extremely small EW-7811Un USB wireless adapter looks like the perfect WiFi adapter for the Raspberry Pi. Not only is it tiny and relatively inexpensive, it also seems capable enough to be a great companion device for the Raspi. While elinux still shows that some users […]
