A bug in version 1.6.1 caused the service to malfunction without a DMX controller. I therefore fixed the problem and provide version 1.6.2 for download.
I added a few more features to the LED Ring Service. It now allows to control DMX devices in addition to the LED ring. The countdown feature for dslrBooth was enhanced too. It allows to display an alternative light effect at a configurable percentage of the countdown. The ring may be switched e.g. at 90% countdown completion to blinking.
The new version may be downloaded here.
