Using an Arduino (AVR) for accurate time

Posted on May 4, 2013 by robertwilkie

This is a good post that gets into timers on microcontrollers.  The author basically is using the clock cycle and interrtupts on the AVR to figure out how many seconds have gone by, so that way its telling “human” time … Continue reading →

Another arduino lock

Posted on May 1, 2013 by robertwilkie

I like this one better, it basically is a deadbolt that unlocks when electric is applied to it (so its not always on).  Only downside is the hardware is hard to come by now (this was written 3 years ago). … Continue reading →

Opensource stepper motor driver, EasyDriver

Posted on May 1, 2013 by robertwilkie

I like this project, you can buy them at sparkfun by the way for $15, or cheaper on ebay.  I hate using either a shifter, or 4+ output lines to control a stepper.  This looks like a nice alternative for … Continue reading →

RFID door lock with an arduino

Posted on May 1, 2013 by robertwilkie

Been looking at door locks again, stumbled across some interesting projects.  This one an arduino based door lock that releases the door “latch” to unlock it.  So the manual lock can still work.  Not so sure I like the “latch” … Continue reading →

Make a shimmering dress

Posted on April 26, 2013 by robertwilkie

Oh the ideas…I think I know what to do for a haloween costume for the kids.  The only downside to this project is the cost.  If I am totaling up the hardware right, the one dress will run you $100 in materials. … Continue reading →

Arduino Uno vs RPi vs Beaglebone

Posted on April 23, 2013 by robertwilkie

Nice article comparing the three boards, I was a little disappointed that didn’t include TI’s MSP which would be comparable to Arduino in A/D and is very cheap.  Actually I have never really looked at beaglebone since they are $99 … Continue reading →

Bluetooth controlled stepper motor

Posted on April 23, 2013 by robertwilkie

Took me several reads to get what the author is doing.  Basically the author uses an atiny (arduino) to control a steppermotor.  The atiny gets its input via a serial connection to a bluetooth module. Once I figured this out, … Continue reading →

Theres an app for developing Arduino

Posted on April 17, 2013 by robertwilkie

Figures…now there is an app to develop arduino code on android…I just can’t see doing this on a phone, but its there.  And its $3. http://blog.makezine.com/2013/04/15/developing-for-arduino-on-android/?utm_source=feedburner&utm_medium=feed&utm_campaign=Feed%3A+makezineonline+%28MAKE%29

Whoa Nice Shades

Posted on April 15, 2013 by robertwilkie

Nice shades, all controlled by an arduino.  I just can’t figure out how you see while wearing them. http://hackedgadgets.com/2013/04/15/rave-shades-led-glasses/
