Mandelbrot Set Viewer
A few days ago I made a Mandelbrot Set Viewer using a graphic LCD and an Arduino. I made a fun video with a sweet soundtrack and I’ve got all the code and schematics posted.

This is some pretty cool stuff. It’s basically smart OCR for handwritten math.

Tactile Metronome release!
Layne and I have been working on some microcontroller kits for folks to solder up and have some fun with. We’re ready to release the first one, and we’re sure proud of it! It’s a Tactile Metronome. What that means is it’s a little gadget you can tap and it will beep back at you the same rhythm. It shows you the BPM and has tempo adjustment buttons. A really cool part is that you can tap patterns into it and it will tap those back to you as well. We’ve worked really hard on the documentation, and Layne made some really amazing pictures showing how some of the trickier things work in the firmware.
The entire kit is open sourced. More details (and a place to order one!) are over at http://wayneandlayne.com/metronome.
Bloop
The Bloop is the name given to an ultra-low frequency underwater sound detected by the U.S. National Oceanic and Atmospheric Administration several times during the summer of 1997. The source of the sound remains unknown.
Though it matches the audio profile of a living creature, there is no known animal that could have produced the sound. If it is an animal, it would have to be, reportedly, much larger than even a Blue Whale.
Because the Bloop noise originated near the location of the fictional sunken city of R’lyeh from H.P. Lovecraft’s story “The Call of Cthulhu”, the Bloop has been linked to Cthulhu by Lovecraft fans.

Vim: Seven habits of effective text editing
I often times want to increase my Vim knowledge, but the main problem with most vim documentation that I find is there is too much of it! A good article with only a few new things in it actually ends up being incorporated into my vim spellbook more than a list of ten thousand incantations with little expository text.
This piece is written by the main author of vim, Bram Moolenaar. It focuses on coders.
