Ha, simple robot build

This one is pretty impressive build.  With an RPi and some simple motor controllers. http://hackaday.com/2017/05/31/zerobot-is-as-simple-as-it-gets/

Converting a harddrive to a sander…and good info on the motors in the drive

The write up was interesting.  but what really got my attention was the information on how these DC motors work from the harddrives. https://www.instructables.com/id/Hard-Disk-Sander/ https://en.wikipedia.org/wiki/Brushless_DC_electric_motor

Make a remote control snowblower

This is a multi year build.  The author took parts from 2 snowblowers, and electric wheelchair, tossed in an arduino and built this.  I think he says the total cost was around 1200…most in the snowblower/wheelchair bit.  Me…I am tempted….but … Continue reading

Make your own ROV

Robots that can go under water.  Interesting build.  I like how they waterproof the motors. https://www.instructables.com/id/How-to-Make-Your-Own-Rov/

Convert CD motors to work underwater

Nice write up on how to convert a motor to run underwater.  I wonder how many you “fry” before you get it right. https://www.instructables.com/id/DC-Motor-ROV/

Need an opensource electronics project, check codemade.io first

Its like a cross between instructables and thingiverse for electronics.  Mostly mod’s to things like arduinos and RPis for electronics. http://lifehacker.com/codemade-is-a-big-collection-of-open-source-electronics-1789750030 sample https://www.codemade.io/search/camera

CHAP: a cheap arm robot

Interesting build  I haven’t dug too much into it, but it looks like a simple and cheap mobile robot arm. CHAP: Low-Cost Tele-Operated Mobile Manipulator main site: https://mobile-chap.github.io/Web/

Neat small robot arm (littelarm 2c)

This arm is small enough that it should be printable on most hobby 3D printers.  Could be a cool project to do with kids. http://www.instructables.com/id/3D-Printed-Arduino-Robot-Arm-LittleArm-2C/?ALLSTEPS

Simple Stepper Driver

Basically this is a nice write-up on a simple stepper driver with an arduino nano and a EasyDriver board.  Easydrivers are a nice stepper motor controller, but….they are a bit pricy http://www.instructables.com/id/Simple-Low-Cost-and-Accurate-Stepper-Motor-Driver/?ALLSTEPS

Another cool (and simple) robot arm build

This one is a blend of 3D printed parts and pipe.  It looks pretty straight forward to make, and only base for it maybe out of range for a hobby 3D printer to print out.  Oh the thingiverse link is … Continue reading
