During What The Hack!, the BlinkenArea was encircled by construction lights. They were blinking all in a tumble, because they were not phased so far. Since HAR, the construction lights are operated by full flashlight support. The Chaos Construction Light Controller 32 (CCLC32) provides 32 outputs, which can be connected to construction lights, when those are rebuilt in a certain way. A serial interface can receive CCLC32 data from BlinkenOutput. Furthermore, a running light-function is integrated as well.
A scheme and a part list can be found on the CCLS32 page at our Wiki.
