August '15
This page describes work accomplished on the new TMRC layout during the month of August 2015, as taken from the descriptions posted to the club mailing list.
August 28

Alex assembled a storage tank for the chemical plant. A calamity occurred when John P attempted to add new tracks to the layout file. The computer became unable to run the graphical part of its program. The screen looked like this.
Having made this cotribution to the club, John P assembled a cluster of servo-operated switch machines. Shown here with an unpopulated circuit board. The output end of the switch machines.
In addition to throwing the turnouts, each machine must operate a microswitch to change the polarity of frog power. With skill and determination, Prajwal was able to restore System operation.
The System works again! The switch machines in place, with a USB adapter installed to drive them. Ultimately, power and data will arrive over a phone cable.
The wire ends will drive the turnout throwbars. They've deliberately been left a little too long, so they can be trimmed to proper length. The computer is controlling the servos via the USB link. Late summer means entering freshmen are on campus! Alex gave a tour.
