The ABS Signals Circuit Board (289)

Last week I showed you how the ABS circuit published by Jeff Scherb in the March 2001 issue of Model Railroader magazine actually works. This week I want to followup on that video by showing you how you can build the circuit boards for the ABS system and install it on your model railroad.

To download the material I mentioned in the video go to my Wordpress website https://larrypuckett.wordpress.com and click on the download link.

The EasyEDA website is https://easyeda.com
You can login using your Google account, then select the Standard version of EasyEDA. When the project page opens enter "Detector logic 2" into the search box at the top of the page. When the search is finished click on the “modules” directory and you should be able to access the file.
