Redo on the mearm

Posted on August 20, 2015 by robertwilkie

MeArm, was a neat cheap robotic arm.  It seems someone redid the design so it better for printing with a 3D printer, and can use steppers instead of servos. http://www.bajdi.com/mearm-forked/

Use Blynk to controll your device via your phone

Posted on August 11, 2015 by robertwilkie

I haven’t heard of Blynk before, but it apparently is another way to controll IoT remotely from your phone.  It woks with arduino, RPi, ESP8266, Particle Core (No Idea on that one). and other stuff.  The article of course mentions … Continue reading →

Simple Peristaltic pump

Posted on July 30, 2015 by robertwilkie

Nice pump that you can 3D print out and use with a stepper for precise control.  All controlled with an arduino http://hackaday.com/2015/07/29/university-peristaltic-pump-has-hacker-heritage/ http://blogs.rsc.org/chipsandtips/2015/06/26/diy-peristaltic-pump/

Peristaltic Pumps

Posted on July 21, 2015 by robertwilkie

So I have been thinking about 3D printing with other materials.  Problem is there is not a whole lot out there on different materials, creamy likey ones, and how to use them.  I stumbled on this article on using a … Continue reading →

Cheap motorized turntable

Posted on July 20, 2015 by robertwilkie

Nice simple and cheap build for a motorized turntable.  This could be a good adaptation to convert into a 3D scanner too. http://www.instructables.com/id/Motorized-Display-Turntable-for-12/

Autopilot R/C boat

Posted on June 9, 2015 by robertwilkie

Interesting build where the author built an his own autopilot based boat.  Using homebuilt arduinos and GPS.  Pretty interesting build. http://hackaday.com/2015/06/01/simple-autonomy-with-an-rc-boat/

Cool 3D Printed controlled syring

Posted on June 2, 2015 by robertwilkie

The authors goal was to build a cheap syringe for medical devices.  But I could see this in a cake CNC or robotics too. http://www.instructables.com/id/3D-Printed-Syringe-Pump-Rack/

How to build tank treads with bike chains and still use gears to drive them

Posted on May 7, 2015 by robertwilkie

Nice idea where the author doubled up the chains so that one side could be driven with a gear, and the other side have bolted tracks on it.  The downside, you have to break each ligament in the chain and … Continue reading →

Need rollers for a conveyor belt, well use paint rollers

Posted on May 5, 2015 by robertwilkie

I stumbled on this write up by accident.  The author made a conveyor belt system using paint rollers for the belt supports and ends.  I thought it was a good and cheap solution so I posted it up. http://www.instructables.com/id/Lightweight-Conveyor-Belt/?ALLSTEPS
