Need (or want) to Control Your Lights with Your Phone?

Spark: Upgrade Your Lights with Wi-Fi and Apps - RF Cafe"Spark: Upgrade Your Lights with Wi-Fi and Apps" That is the tag line for a Kickstarter™ crowdfunded project that seeks to commercialize a device that screws into a standard light bulb socket and wirelessly controls a bulb (up to 100 W) which is screwed into it. Evidently the product is already designed and tested, so all the development and marketing team needs now is enough cash to do FCC certification (due to the switching power supply, controller, and WiFi signal) and a production launch. As of this writing there are 1,162 Backers, and $92,189 has already been pledged toward the $250,000 goal. They have 13 days left to reach the goal, or the entire effort has to begin all over. Spark needs a WiFi router within about 200 feet, and will only work with dimmable bulbs, which includes Edison's evil Earth-killing incandescents, LEDs, and dimmable (but not standard) CFLs. I did not see a target retail price. The team has a very well-done presentation for their effort.
