It seems to be a slow day for blogworthy LEGO creations, so I went back through my bookmark archive and ran across something we really should have blogged the second we got the link — Chris Meyer‘s how-to guide on making plastic LEGO train tracks backwards compatible with legacy 9-volt and 12-volt systems.
The problem (and benefit, depending on who you ask) with current Power Functions and RC systems is that they’re battery-powered. For LEGO convention attendees and train show participants who may run their trains for hours at a time, this means stopping everything in the middle of their layouts to replace the batteries, over and over again.
But since LEGO no longer produces externally powered trains, the tracks are exorbitant on the secondary market. Chris solves this problem by applying conductive foil tape to easily purchased plastic tracks. It’s a cheap solution, and looks much less time-consuming than sifting through eBay.
