LibAPCNIS is a PHP library for accessing the NIS port of the Apcupsd UPS Monitoring daemon. It allows you to access realtime UPS stats from a PHP script without having Apcupsd installed. It does not require the apcaccess application included with an Apcupsd installation, and there are no external dependencies.
RC Flyers Toolkit Box is a handy toolbox for R/C pilots. It helps you manage batteries, flights, charge cycles, and check lists. It helps you keep track of which of your batteries are charged, where and when you have been flying last, how much went in your battery compared to the last cycle, what you have to pack to take with you, and which parts you have to check before flying. For rotary wing users, there is a pinion calculator that quickly gives you an idea about the RPM to be expected.
