IR Codes (aibohack.com/robosap/ir_codes_quad.htm) The RoboQuad modulation scheme is the same as the RSV2 12-bit encoding described at the top of the IR Codes V2 page. The first 4 bits are "0110" for the RoboQuad (hex $6). Movement Commands (direction pad) $600 + SHIFT ($600,$620,$640,$680) = stop$601 + SHIFT ($601,$621,$641,$681) = forward$602 + SHIFT ($602,$622,$642,$682) = backward$603 + SHIFT ($603,$623,$643,$683) = left$604 + SHIFT ($604,$624,$644,$684) = right$605 + SHIFT ($605,$625,$645,$685) = top+left$606 + SHIFT ($606,$626,$646,$686) = top+right$607 + SHIFT ($607,$627,$647,$687) = bottom+left$608 + SHIFT ($608,$628,$648,$688) = bottom+right SHIFT = $00 (shift level 1, LED off), $20 (shift level 2, green), $40 (shift level 3, orange) or $80 (shift level 4, red).

10 Raspberry Pi creations that show how amazing the tiny PC can be The Raspberry Pi, the $35 credit card-sized computer, has lived an interesting life despite being less than a year old. It has been used to teach programming and host servers, but above all it has provided a near-perfect platform for some of the most fun and interesting hobbyist projects in the computing world. Arcade cabinets, computing clusters housed in LEGOs, musical instruments, robots, and wearable computers are just some of the uses Pi owners have found. It turns out you can do a lot with an ARM processor, GPU, a few ports and GPIO pins, and an operating system (typically Linux-based) loaded onto an SD card. Here are 10 of the coolest Raspberry Pi creations we've been able to find. A Pi-powered arcade cabinet
Radical Breeze Read On, to find out what it is all about, what you can get. (We try not to sound too ‘hyped’ but we are proud of the software and truly believe every ISC user could find it useful) NOTE: Please do NOT share this with anyone else. Seriously, it was negotiated as part of the deal ONLY FOR RADICAL USERS. It is not even being offered to Dead Parrot customers or the public.
View topic - LiquidTWI: High-performance LCD library for I2C Backpack Module I like fast things. And I like clean code. Often, the two go hand-in-hand ;) After looking through the modified LiquidCrystal library for use with the i2c backpack and darn near crying when I saw all the faux digitalRead() and pinMode() being done on each transfer, I was bound and determined to never let that happen to another friendly Arduino user again. I first made a proof of concept modification to the library to "burst" all the "LiquidCrystal::send" bits instead of digitalWrite()'ing them out one at a time (read I2C, modify, write... read, modify, write... read, modify, write... read, modify, write - over 16 I2C commands for each single character).

Checking Your IR Remote and Replacing Your IR LED in the Roboquad: RoboCommunity Wait! Don't throw your batteries away in your remote until you do this check! If this check doesn't work, the problem may be your IR LED. If you didn't see that in your digital camera, then it just might be the IR LED, a transistor, or the CPU. 64 Rasberry Pis turned into a supercomputer Return to View video at: Prof Simon Cox Computational Engineering and Design Research Group Faculty of Engineering and the Environment
Visual Programming Arduino: modkit and the others Not long ago, our friend [Ed Baafi] told us about the amazing work he was doing on ModKit: a very interesting project in bringing visual programming on the Arduino side. Making programming as easy as building bricks is the common Quest of many different projects, aimed to work in the Educational field, teaching kids build their own programs (and toys). Modkit is an in-browser graphical programming environment for little devices called embedded systems.
