Arduino battery shield build

Posted on September 21, 2015 by robertwilkie

Nice build that takes an cell phone battery, and power converter circuit and a charging circuit, to make a battery pack shield for an arduino. http://www.instructables.com/id/Arduino-Battery-Shield/

Make an arduino based laser rangfinder

Posted on September 17, 2015 by robertwilkie

Interesting project, not much hardware work involved.  Down side, the !@#$# laser module is $300 dollars.  Bit out of my price range. http://hackaday.com/2014/07/01/pew-pew-an-arduino-based-laser-rangefinder/?utm_source=feedburner&utm_medium=feed&utm_campaign=Feed%3A+hackaday%2FLgoM+%28Hack+a+Day%29

Make your own skittle sorter

Posted on September 10, 2015 by robertwilkie

OK I know this has been done before with arduinos.  But this time all the “parts” you can print out instead of having to cobble them together from god knows where.  Its a cool build and has alot of thought … Continue reading →

Nice write-up on upgrading a Chinese 3020 CNC

Posted on September 9, 2015 by robertwilkie

Good write-up on how to upgrade an $800 CNC from China to be more modern and robust.  My 2 cents, I think I would spend the money on a shapeoko instead. http://www.instructables.com/id/3020-CNC-Arduino-GRBL-CNC-Shield-V3/

Upgrading an old alarm system with an arduino

Posted on September 8, 2015 by robertwilkie

It looks like the author reverse engineered a few bits on an older alarm system to give it some more modern features. http://hackaday.com/2015/09/05/upgrading-your-alarm-system-with-an-arduino/

Another CD-ROM to Mini CNC build

Posted on September 4, 2015 by robertwilkie

This is a nice build and cheaper than some of the other ones I have seen.  The author uses a smaller Arduino, and L293D chips to keep costs down.  Of course he ups the costs with other stuff. http://www.instructables.com/id/Mini-CNC-Plotter-Arduino-Based/

Build a garage door opener with a Particle core and Blynk

Posted on September 3, 2015 by robertwilkie

Particle Core is another arduino like clone that supports wifi.  The author combines it with Blynk, a simple tool to control the arduino via android, to open/close a garage door.  I am not sure how secure this is against something … Continue reading →

DIPDuino, arduino with a bunch of stuff loaded on a DIP

Posted on September 2, 2015 by robertwilkie

This thing is amazing, LED, wireless, etc etc all packaged on a DIP board (so you can put it on a breadboard or other stuff).  Be interesting what the end cost will be. http://dipduino.com/

Using the L298 with arduino for Dual DC motor controll

Posted on September 1, 2015 by robertwilkie

Again, I know I have shown a few of these before, but this is one of the first ones with a good wiring diagram. http://www.instructables.com/id/Arduino-L298-motor-driver-integrated/

Another arduino controlling stepper motor write-up, BUT has nice diagram

Posted on September 1, 2015 by robertwilkie

I know, you have seen these before.  But this one has a nice chart for showing wire color codes for some common motors. http://www.instructables.com/id/Controlling-Bipolar-Stepper-Motors-with-Arduino-wi/
