We had another really excellent Hardware meetup tonight at c4di. What surprises me about the events is that we get people walking in with awesome projects and things they've built. Last time we met up Andrew was showing us the thing he'd built above. Just because he'd only got one of his two robot motors hadn't stopped him from building something really neat.
The two "eyes" at the front are a distance sensor. You can place Andrew's device in the middle of the room and it will spin round and generate a polar plot of the distance of objects around it, measured by the ultra-sonic distance sensor and transmitted via WiFi to a web page hosted out of the device itself. The leds are to show the motors being driven, and just to look awesome.
Tonight we also had Brian showing off how he was using Blink to wirelessly connect sensors together and also provide remove monitoring via an iPhone app. And Steve demonstrating a really neat Raspberry Pi powered wildlife camera which automatically converted it's camera from infra-red to normal during daylight hours.
Great stuff. If you want to come along and show us what you're up to (or just find out how you can build something awesome) you can sign up for our next event here, or just come along to c4di and say hello at our next Meetup on Thursday 6th of April.
