Build your own robot mower

Posted on September 18, 2013 by robertwilkie

Except I don’t think this one actually has blades to mow the grass yet.  Nice looking build thought.  Me…maybe an old wheelchair would be a better platform to start with. http://www.instructables.com/id/ArduMower-Do-it-yourself-robotic-mower/

Another interesting costume with an Arduino and LEDs

Posted on September 18, 2013 by robertwilkie

This is using the Lilypad arduino, which basically is a lower power and smaller form-factor arduino oriented towards being added in clothing.  You can get them a lot cheaper on ebay than sparkfun.com thought. http://www.instructables.com/id/How-to-make-a-LilyPad-Arduino-LED-skirt/

Interesting Jellyfish costume with Arduino and LEDs

Posted on September 18, 2013 by robertwilkie

I am more interested in the tech than the costume.  Could be useful to apply to more advanced costume than a see-thru raincoat with LED strips.  Thought the author mentions Adafruit stuff would be a easier solution, his method is … Continue reading →

Google Authenticator with an Arduino to open a door

Posted on September 15, 2013 by robertwilkie

Interesting hack where the author uses Googles authenticator (OTP I believe) to get tokens to provide to the arduino to authenticate with.  Which the video was in english. http://hackaday.com/2013/09/14/using-google-authenticator-with-an-arduino/?utm_source=feedburner&utm_medium=feed&utm_campaign=Feed%3A+hackaday%2FLgoM+%28Hack+a+Day%29/

Swapping LEDs with motors on a LED strip

Posted on September 11, 2013 by robertwilkie

  I am still trying to figure out why I would do this, or what I would use it for, but its pretty cool.  The author basically took an LED stripe and replaced it with mini motors and controllers. http://hackaday.com/2013/09/11/switching-leds-with-motors-on-a-led-strip/?utm_source=feedburner&utm_medium=feed&utm_campaign=Feed%3A+hackaday%2FLgoM+%28Hack+a+Day%29

Write-up on serial communication with ATiny

Posted on September 10, 2013 by robertwilkie

Nice intro into doing serial communication with ATTiny.  Why?  well ATiny’s are cheap, and low power, but they do not have much for I/O, so serial communication is a good alternative. http://www.instructables.com/id/Easy-ATTiny-Serial-Communication-with-Tiny-AVR-Pro/
