LeakBot and Flo water valve. Both designed to monitor the flow of water in your home and let you know if you have a leak (a burst pipe will just keep going and going...) #>
Softbox Light, using an old bicycle wheel and LEDs. This really turned out nice, I can see it being great for ambient light. #>
ESP8266 Wi-Fi - SCREW SHIELD. I really like the idea but it ships from Poland, so it's $9 additional shipping for 2 of them, that's a bit tough to swallow (nothing against the creator, just a shame it costs so much.) #>
Helios4 Personal Cloud - The Open Source NAS. Not the cheapest option but being open source is a nice bonus. #>
UPS PIco - Uninterruptible Power Supply & I2C Control HAT. Ohhh, power outages kill Raspis so this is amazing. #>
Android Phone as Server. Interesting idea but I think I'll stick with a Raspberry Pi for $30... #>
First and last freeze/frost dates for Denver, CO ,United States. That's super handy (just put in your zip code). Would have been handier a week ago when I planted and then it snowed two days ago... #>
