Today is Black Friday, the bustiest shopping day in the US. Every kit-biz is promoting their wares (Adafruit, Make, HacknMod), here’s our plug.

In the past three months we’ve released three geeky open source projects that you can buy at Seeed Studio:

Seeed also has some accessories, such as:

We’re proud to work with Seeed Studio to make copies of our open source projects available. When there are cheap rapid prototyping machines you’ll be able to print our projects at home, until then, there’s Seeed Studio. Seeed has inexpensive worldwide shipping starting from $2.85, most of our projects include shipping in the cost.

The hackable holiday ornament kit is for adventurous solderers who want to practice with surface mount components. Seeed only made a few of these, get one while they last. Kits are $12, and Seeed will assemble yours for $3 more (assembled card, $15).

The #twatch is the Twitter addict’s best friend. This stand-alone network appliance shows a continuously updated stream of Twitter topics and tweets. It also displays PC stats from programs like LCD Smartie. Currently in stock at Seeed Studio for $45 with an LCD, $30 without, including worldwide shipping.

For every hardware hacker, there’s the Bus Pirate. Figure out a new chip without writing code, program AVR microcontrollers, and more. Forget elegant abstraction, learn about electronic interfaces at a very low level.  The next batch will be ready to ship the first week of December. $30, including worldwide shipping.
