Nice tutorial on different motors and how to use them

I will have to remember this one for the future to help kids with motors.  Good write-up and intro into different motors out there. http://www.instructables.com/id/Complete-Motor-Guide-for-Robotics/

Another nice CD-ROM based laser engraver

These seem to be growing in popularity to build lately.  Here is another write up to build on with an arduino to control it.  I like the box the author built for this too.  I like the safety measures the … Continue reading

Nice intro to the TB66 for motor control

Nice write-up on using the TB66, and h-bridge chip/board, for controlling a DC-motor.  I used to make my own h-bridges out of scrapes, but this looks like a good and easier alternative.  They run about $5 on ebay. http://www.instructables.com/id/MOTORS-BASICS-Finally-HOW-TO-USE-AN-H-BRIDGE/

Another CDROM CNC plotter

OK I know, there have been lots of these builds, and you can even “buy” one for $100ish these days.  But this is one of the cleanest looking builds of a CDROM CNC I have seen yet. http://www.instructables.com/id/Arduino-Mini-CNC-Plotter-Machine-from-dvd-drives/

Building a laser engraver on the cheap.

And cheap it is.  The Y is an old printer carriage, X is an old flatbed scanner.  An arduino with homemade motor controllers is controlling everything.  Hold on, I think he is using stepsticks…it seems to switch.  The laser is … Continue reading

Make an automated cat toy

Too funny, the author built a cat toy that moves the motor when motion is detected.  He is using an arduino like device called WIZWiki (New one on me).  It does with ethernet build in.  My 2 cents, I think … Continue reading

How to setup an RPi without a monitor

The write-up is for the new Raspberry Pi Zero, but…you do the same thing for normal Pi’s too. http://davidmaitland.me/2015/12/raspberry-pi-zero-headless-setup/

Swift is now opensource

First Microsoft releases a lite version of Visual Studio for users in Linux/Mac, now this? Its amazing to see corporations opening up their tools and software in order to get “developers” to adopt them. http://techcrunch.com/2015/12/03/apples-swift-programming-language-is-now-open-source/?ncid=rss&utm_source=feedburner&utm_medium=feed&utm_campaign=Feed%3A+Techcrunch+%28TechCrunch%29#.806qgy:Y55k
