Another automated turret build

This one is a bit interesting since it seems to shoot bursts out instead of single shots.  The difference from past ones is no arduino involved (RPi and a hat for motor control), and no laptop to do image processing/etc. … Continue reading

OK this is pretty funny

The author built a simple robot that climbs up a rope, and then cuts the line. Oh and falls down to the ground too. http://www.3ders.org/articles/20170702-diy-3d-printed-ropebot-can-climb-trees-and-cut-down-ropes.html

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

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
