Wireless Bootloading
Checkout the new tutorial using the AVR ATmega168 with XBee wireless modules to create a very robust serial bootloader! We also posted a new GeoChron Blue GPS product, programmable oscillator, photocell, and a mux breakout.
We've posted a new tutorial describing how to reliably download code to an AVR ATmega168 using a XBee serial link. We created our own bootloader and modified our old Screamer VB app to make a really robust wireless bootloader. Checkout the video!

We've also got a new GPS logger with Bluetooth? capabilities. The GeoChron Blue is a great way to record vehicle or personal location. It can be charged using an 12V automotive connection and store many weeks of data on a removable SD card. The data can also be acquired over a Bluetooth? wireless connection. Very handy!
We now stock very simple, low-cost photocells. These great light sensors can be used as a trigger, detector, or simply as a sensor for your next interactive project.
This is a basic breakout board for a very helpful IC. The CD74HC4067 is a 16 channel multiplexer/demultiplexer. This allows up to 16 sensors to be connected to one ADC pin. Great for those large scale proximity challenges.
And finally for today, we have a programmable oscillator. This is a neat IC that can generate any frequency with software control (I2c). This IC can output 8.1kHz to 133MHz without any external components! +/-0.5% so it's better than an internal oscillator on a normal microcontroller, but not as accurate as a quartz crystal.
