Simple proximity sensor for Arduino

Posted on October 15, 2013 by robertwilkie

Nice write-up and I think this is cheaper than buying a prox sensor. http://makezine.com/projects/use-a-diy-proximity-sensor-to-automate-your-haunted-house/?utm_source=feedburner&utm_medium=%24%7Bfeed%7D&utm_campaign=Feed%3A+%24%7Bmakezineonline%7D+%28%24%7BMAKE%7D%29&utm_content=%24%7BGoogleReader%7D

Interesting garage door remote control

Posted on October 15, 2013 by robertwilkie

Interesting build using an RPi as the controller.  The author built his own shield to control and get status on the garage door.  I like the use of magnets for sensors to determine if the door is open or not. … Continue reading →

Make an Anemometer

Posted on October 14, 2013 by robertwilkie

Nice write-up on making an anemometer.  I was a little concerned on using the cheap plastic that the sun would destroy it.  But the author gave it a coat of paint that seems to cure the problem. http://www.instructables.com/id/Data-Logging-Anemometer/

Use an Oscilloscope to See Your Pulse

Posted on October 10, 2013 by robertwilkie

A bit overkill to get your pulse, but if you don’t have another way to do it…and want the cool graph of it. http://makezine.com/2013/10/10/use-an-oscilloscope-to-see-your-pulse/?utm_source=feedburner&utm_medium=%24%7Bfeed%7D&utm_campaign=Feed%3A+%24%7Bmakezineonline%7D+%28%24%7BMAKE%7D%29&utm_content=%24%7BGoogleReader%7D

Using an RPi with a Gieger Counter

Posted on September 25, 2013 by robertwilkie

Its actually using a daughter board (shield for your arduino folks) that has all the gieger hardware (called the PiGi) and the board is opensource.  It sounds like it would cost around 40-50 dollards to get the board made in … Continue reading →

Another nice write-up on a zero probe tool for CNC (maybe 3D printer too)

Posted on September 10, 2013 by robertwilkie

Nice write-up on using a zero out probe to level out a table.  or find out where the high/low of the table is.  The author has the feedback go thru a limit switch point on the controller to get the … Continue reading →
