Using an RPi to control a CNC over WiFi

Posted on March 16, 2015 by robertwilkie

Nice write up on using an RPi to control a CNC with something called GRBLWeb, which is a remote for CNC control of a system.  Reality you are using an Raspberry Pi and an arduino in this project. http://www.instructables.com/id/Control-your-CNC-over-Wi-Fi/?ALLSTEPS

Simple Large CNC for Laser Engraving

Posted on March 10, 2015 by robertwilkie

Another nice CNC build that makes for a large cover area and somewhat portable for engraving.  I haven’t ventured into lasers yet, mostly out of safety concerns.  But this looks like a nice build and cheap to make. http://www.instructables.com/id/3W-4×4-Arduino-Laser-CutterEngraver/

A cheap ($100) CNC/3D printer

Posted on March 10, 2015 by robertwilkie

I had to post this one.  The author basically takes parts from a printer carriage and other stuff and slaps a 3D printer together.  All for around $100.  I like the Arduino and RAMPS 1.4 setup.  Haven’t tried it myself … Continue reading →

Build a lawnbot

Posted on March 3, 2015 by robertwilkie

I have been wanting to build something like this for years, just haven’t had the time to justify it.  SO I will post someone elses build.  Parts that concern me on this build is the removal of the deck wheels.  … Continue reading →

Build your own light up hoodie

Posted on February 27, 2015 by robertwilkie

Interesting build where adafuit uses a pull method to light up a hoodie light.  I would just use a switch myself. https://learn.adafruit.com/textile-potentiometer-hoodie

Using a zipper as a switch

Posted on February 27, 2015 by robertwilkie

Nice idea, basically use the zipper to trigger a switch to an arduino. https://learn.adafruit.com/zipper-switch

Arduino Basketball Shot Counter

Posted on February 24, 2015 by robertwilkie

This build is based on this one which was a bit more costly.  I like this build cause I could build off of it to have something that keeps stats too.  Oh an arduino is used to keep tabs on … Continue reading →

AES encryption on an ATiny

Posted on February 23, 2015 by robertwilkie

The author managed to get AES running on an ATiny for building a secure channel for a doorbell.  This is neat and I am impressed that it was done (in assembly no less). http://hackaday.com/2015/02/20/aes-cmac-on-an-attiny85/

Another simple CNC build with an arduino

Posted on February 20, 2015 by robertwilkie

I have been seeing a new interest in home built CNC’s lately.  This one the author built for $200 Euro (230 US).  I think he could have gone cheaper (there is a nice simple CNC with arduino clone on EBay … Continue reading →

Simple tester for Steppers with an arduino

Posted on February 20, 2015 by robertwilkie

Nice write-up on how to setup and test a stepper motor relatively quickly.  This could come in handy in the future as I have been pulling steppers out of junked printers from the side of the road or dumpers and … Continue reading →
