Swedish hacker [Hans Andersson] is no stranger to puzzle-solving robots. His prior work, A Rubik’s cube-solving robot called Tilted Twister, made waves through the internet last year. [Hans’] latest project only has to work in two dimensions, but is no less clever. This new robot, built around the LEGO Mindstorms NXT system, “reads” a printed sudoku page, solves the puzzle, then fills out the solution right on the same page, confidently and in ink. It’s a well-rounded project that brings together an unexpected image scanner, image processing algorithms, and precise motor control, all using standard NXT elements.
The building instructions have not yet been…

The Atmega168 at the heart of every Arduino is an eminently capable chip; its ilk have been seen working as a basic web server, playing back digital audio, even generating TV signals. But as projects continue to grow in sophistication, reality rears its ugly head: Arduino can handle any one of these tasks very well, but it often requires squeezing every last instruction cycle or bit of memory in the device. Even the ’368 chip and the Arduino Mega are stopgap measures. Sooner or later, you have to graduate to long trousers—move up to a more capable microcontroller platform—an uncomfortable change usually involving…

Under a month after writing about Zynga surpassing the 60 million user mark, the company has now grown beyond 80 million monthly active users. A large portion of Zynga’s success is a result of their FarmVille application which is about to become the largest application on the platform at some point next week. While some companies have developed highly successful applications (LivingSocial was the largest application on the platform ever), no companies on Facebook have as large of a portfolio as Zynga does.

They have almost doubled the size of their closest competitor (Playfish) and are simply dominating the platform.…

Sometimes we have no option to select people who we doesn’t want to meet with. Again and again we have to face them; it is not quite right to say they’re bad; the fact is we’re in the wrong channel, perhaps we differ in patter and style.Back to the of trust, I could tell you that the only thing we should count on – Payback.

A little over a year ago [Ian Lesnet] joined our hacking team and began cranking out some of the best original how-tos Hack a Day has ever offered. You may remember our popular web server on a business card from last fall and we’re sure everyone is familiar with the Bus Pirate (yes, they’re still on schedule).
It’s a year later and he’s found himself with less time to contribute. [Ian] is stepping down from blogging at Hack a Day, but you’ll find him right where he started: in the comments. You can also reach him directly on whereisian.com.…
