How to Build a DC Sensor Tester / Demo Box
By Chris Elston
Here are some pictures and a PDF of a diagram to build a DC sensor test box. It's dual NPN or PNP output with an off/on switch. All parts purchased at Radio Shack for under $20.00. Do not buy the same size box buy the next size bigger project box than what is shown in the pictures. I had a hard time getting two 9 volts crammed into this tiny enclosure.

Video - Beginners Ladder Logic Part 1 of 2 - Halloween
By Chris Elston
For the past four years I have setup a Halloween display at my house for my neighborhood children to enjoy. Each year my total TOTs (tricker-or-treaters) have double to the point last year I had 1500 kids come through my garage for a fully automated Halloween show complete with animatronics air props etc.. Also each year I submit a DVD video in a contest to the Halloween-L people in hopes to win the contest for the USA. I never have won anything but this year I decided to contribute to the technical part of the contest so I video taped myself going over the basics of a MicroLogix 1000 PLC and how I apply my PLC at home for use during my Halloween displays.
Last year is the last time I will be setting up my display however my legacy lives. I put up a website with videos and pictures of my props from the past three years. You can view or see more information at: http://www.plchalloween.com. Since I won't be returning to the Halloween scene in 2006 I've decided to share my videos I created. I will uploaded a series of videos to MrPLC.com as I see they can help those that are beginners much like they have helped Halloween-L fans.
Very soon check in the online store I will release a DVD version of all my How-To-PLC w/Halloween for sale. The DVD will contain hi-quality videos however the low quality videos will remain free for download here at MrPLC.com. I hope you enjoy as I upload videos in the next coming weeks.

SerialKeys triggering of Protocol Analyzer
By Ken Roach
I use a lot of protocol analyzers but most of them lack good event triggers other than time or buffer size. If I'm looking for an event (or non-event) on my automation network that my PLC can detect I want the PLC to stand by all night waiting to push the "pause" button so I don't have to wade through megabytes of buffer data to find the problems.
This example uses a Windows Accessibility function called "SerialKeys" to allow a PLC to "push the button" on your PC running an analysis tool.

Content-centric networking
By neilr216
Content-centric networking (also content-based networking) is a new approach to the architecture of computer networks notably pioneered by Van Jacobson.
Its founding principle is that a communication network should allow a user to focus on the data he or she needs rather than having to reference a specific physical location where that data is to be retrieved from. This stems from the fact that the vast majority of current Internet usage (about 90% [1]) consists of data being disseminated from a source to a number of users.
The current architecture of the Internet revolves around a conversation model created in the 1970s to allow geographically distributed users to use a few big immobile computers.[2] The content-centric approach seeks to make the basic architecture of the network to current usage patterns.
The new approach comes with a wide range of benefits one of which being building security (both authentication and ciphering) into the network and at the data level.
Despite all its advantages this idea doesn't seem to map very well to some of the current uses of the Web (like web applications where data is generated on the fly according to user actions) or real-time applications like VoIP and instant messenging. But one can envision an Internet where content-centric protocols take care of the diffusion-based uses of the network creating an overlay network while genuine conversation-centric protocols stay on the current infrastructure.

Controlling another application with VB.NET
By panic mode
Small demo how to write program that uses another application (any). In this demo (VB.NET source included) remote application is Windows Calculator.
Things to note:
- launch check if running and close remote app
- issue commands such as minimize maximize and restore (note that this works even if actual icons in upper right corner are grayed out this only prevents access in normal use not when accessed remotely like through API)
- read and write text from/to remote app (also works if user cannot see remote app like when minimized etc.).
- issue mouse clicks (to be effective should not be affected by user moving mouse cursor and should not interfere with user interaction with computer)
- it can focus on and control specific instance of the application (try to run several Calculators) etc.
panic mode
PS. To really see what is inside remote app you want to manipulate (check class caption etc.) you will need program like ShowWindow http://www.thescarms.com/VBasic/ShowWindow.aspx
