12:25 AM rue_shop3: patiently waiting for that "OOOOH!" moment

12:57 AM rue_shop3: generate, 3w?
12:58 AM rue_shop3: the tails seem wrong
12:59 AM ^kat^: plus the cost to build means you will never get more power out to break even on it, and they both look bad
12:59 AM rue_shop3: I need a few w for my yard lights when the suns not happy
12:59 AM rue_shop3: 3w would do fine
