Got a new kit for you - the K SMD L293D Motor Driver. No, no, the SMD isn't "surface mount" - it's the Secret Motor Driver! This L293D-based motor driver fits secretly inside most standard servo cases like the Futaba S3003/S148, and our own GM4 gear motors.

3D Printed Treetop Star
Solar botics
December 9, 2014
Initially inspired by the Moravian Star on Instructables and the fact that we now carry all kinds of 3D printing filament, we decided to make one of our own glowy holiday star. We have used this thing as source files to create a similar treetop decoration of our own.
After some trial and error (due to the Slicer not cooperating)...
...we printed a whole forest of perfect wintery spiky star-ends.
And, well, we just had to have someone live there for a bit. In this case, a snowman:
Our addressable 5mm LEDs were well suited to light this contraption. We drilled a hole in the bottom of each spike..
..to fit the LED's domed part:
And then wired everything up. It wasn't pretty but the WS2812 LED that we used made it much easier than a conventional RGB LED: rather than 3 separate channels, the WS2812 LED only has a data in and data out. Chain them all together and they work like a charm!
And here's the final product, ready to light up our office with wonderful glowing lights!
