I have been trying to make a F5229 Launchpad and CC3000 work like a Belkin Wemo, in the sense that I could use it to switch appliances such as heaters and lights in my house on and off from a remote web site (or iPhone/Android) without the need for a server within my house. My whole project would use about 20 devices. The problem one immediately faces is getting past the NAT in a domestic router. I have studied subjects such as STUN, TURN & ICE and uPnP and spent rather more time than I should have on failed attempts at UDP Hole punching. This is clearly possible, since the Wemo
I just got a really nice Tado home heating control system. It can be accessed remotely, detects when you're there and looks really slick. Sort of like a Nest, but seems much better - more substance rather than just styling. http://www.tado.com It's currently in beta in the UK and whilst trying to identify a couple of wrinkles (due to my crappy Sky router) I got chatting to one of the developers.

Hi everybody, As a part of my long term project building wireless sensor nodes, I have been looking for a nice RTC chip. First I was drawn to the DS1307, but this part is 5V and only a clock without alarm functions. Googling to the internet I've found the PCF8563. This part is a "drop in" replacement for the DS1307, but offers a lower supply voltage (3.3V) and includes alarm functions. The chips can be sourced quite cheap from the internet and work like a charm with both 6pf and 12pf 32768kHz crystals. A nice tutorial how to connect these things can be found using the following link: h
