Cool CNC plotter robot arm build

Posted on February 6, 2020 by robertwilkie

Nice build, the author laser cuts all the parts and uses 3 cheap servos to power it. Pretty nice looking build https://www.instructables.com/id/SCARA-Robot-Learning-About-Foward-and-Inverse-Kine/

A ball bearing pick and place machine

Posted on January 31, 2020 by robertwilkie

The author designed and printed out a robot arm with vacuum to move ball bearings around. Neat build and is more for the classroom than practical purposes.

Wine bottle engraving CNC

Posted on January 30, 2020 by robertwilkie

Nice build. The author basically build a CNC engraver for bottles. it can also draw and convert to a standard CNC. You can 3D print the parts from here: https://www.thingiverse.com/make:374703

Cool robot automated eye build

Posted on January 29, 2020 by robertwilkie

The author uses a couple of cheap servos, an ardiuno, and a 3D printer to make simple eyes that can move around on there own.

Nice skittles sorter

Posted on January 22, 2020 by robertwilkie

The parts are 3D printed out. Its a pretty compact sorter and works well from the video. It uses an arduino for the controller.

Cool infinity mirror

Posted on December 18, 2019 by robertwilkie

Also doubles as a clock. This was alot of work for the author, I wonder if he could have simplified a few steps. https://www.instructables.com/id/Make-an-Infinity-Mirror-Clock/

Cool servo tester

Posted on December 18, 2019 by robertwilkie

It provides the angle of rotation while you use a pot to change it. Nice build overall. The color display is also pretty cheap now these days ($3). Something I may need to keep in mind for the future. https://www.instructables.com/id/Servo-Tester-2/

Nice write up on using L298 with Arduino

Posted on December 16, 2019 by robertwilkie

L298’s are good motor controller (relay) chips. The author found there are not alot of good write-ups on the combining the two. Of course there are many write-ups on using shields that have this chip built in… https://www.instructables.com/id/Connect-L298N-IC-to-Arduino/

Arduino to read off Analog Dialer

Posted on December 13, 2019 by robertwilkie

Nice use for an old phone dialer, and convert the values using an arduino. Then you could use that for something else (maybe build up a phone system with the old dialer). https://www.instructables.com/id/DIY-Analog-Dialer-to-USB-Keyboard/

Interesting review of a cloned D1 Mini Matrix Shield

Posted on December 12, 2019 by robertwilkie

I had not heard of this board before. Apparently not only does it exist to be used to easily control a Matrix LED light, but the author reviewed a clone of his board from China.
