Build a battle bot that can take care of itself

Posted on February 27, 2013 by robertwilkie

Small, some  parts  could be swapped out with cheaper solutions, except that arduino stuff 🙂  Either way this build is nice since it could smash the other bots on its own (without user control). http://www.instructables.com/id/My-Mini-Sumobot-500g-Prototype/

An Arduino O-Scope

Posted on February 23, 2013 by robertwilkie

Nice write-up on how to build an oscilliscope with an arduino.  Won’t get record recordings on it, but it will do the job on the cheap if you need one. http://randomnerdtutorials.wordpress.com/2013/02/01/arduino-poor-mans-oscilloscope/

How to control an arduino thru a phone

Posted on February 21, 2013 by robertwilkie

Actually its more of arduino via bluetooth to android phone.  Still this could be useful for custom robots and such.  Just the range of bluetooth is no so great. http://www.instructables.com/id/How-control-arduino-board-using-an-android-phone-a/

Build a Wireless Robot

Posted on February 17, 2013 by robertwilkie

Interesting build with some scrap parts (kids old toys) , a quazi arduino, and other bits.  I think I would have skipped using bluetooth thought… http://www.instructables.com/id/Wireless-Robot-V2-Support-WiFi-Bluetooth/

Control an arduino with TI wristwatch

Posted on February 13, 2013 by robertwilkie

Nice write-up on using TI’s chronos wristwatch (MSP430 under the hood) to control an arduino remotely.  DOWN SIDE, that watch is like $35 dollars. http://www.instructables.com/id/Control-an-Arduino-With-a-Wristwatch-TI-eZ430-Chr/

Zero Cross Detector for Arduino

Posted on February 13, 2013 by robertwilkie

Well actually for Amtel processors.  Its a nice note so you can wire the processor directly and know exactly when a line goes from positive to negative.
