Mac flavor of Ladder Maker

Posted by admin on February 4, 2014

mac.jpg  I'm getting a Mac Mini here soon.  I plan to use it to make an installation of Ladder Maker.  I think the Python and pyQT4 requirement will not be too much of a task, but I will have to build the AVRGCC and Avrdude backends for Mac.  It's been done by others around the 'net, so stay tuned for the Mac version of Ladder Maker.  

Post a comment here if you are a mac user who wants LadderMaker, it will keep me motivated! -Karl

Welcome To the Waltech Blog

Posted by admin on January 30, 2014

wlm87.jpgThis is the first post. Mostly I'll be posting about the Waltech Ladder Maker software which has reached a usable form in the last week. You can get it here : Open Source Designs

We decided on this project to help promote the site and what we do. PLC software is usually expensive and more complicated than it needs to be, so we decided to make an application that would be easy to use with only the basic elements. With the 5 basic elements that Ladder Maker has, you can do almost everything that a PLC does.

We are starting a project that uses an Arduino Uno and Waltech Ladder Maker to control a pellet stove. I plan to use this blog space to publish progress on that project.

The Waltech site is getting a total makeover right now. Some old content was removed, but I plan to use this Blog to bring back some of the old content that folks found useful and interesting. You will be able to see the evolution of Waltech, including past automotive and aviation adventures. --Karl

LadderMaker video

Posted by admin on January 30, 2014

Arduino logo  + Laddermaker.  A couple bugs with the Arduino output have been fixed in version 90.  I made a screencast video with a demonstration using an Arduino Uno:

 VIDEO video-icon.pngHere. 

 The perf-board shield is simply 9 leds on the outputs (covered in tape for the video) and 9 push buttons that pull to ground when pressed.  I hope people will give LadderMaker a try. Let me know about any issues via comment here, or on Youtube, or by this site's contact page. --Karl
