Android 4.3 Bluetooth Smart service caching

Random fact: Android 4.3 caches Bluetooth Smart services. When you change the services on a test device, a reboot is needed or your app will keep seeing the old services. (At least on my Nexus 4)

re-triggerable monostable 555

Quickly prototyping a re-triggerable monostable 555 based on this page: m8051.blogspot.be however I prefer the PNP variant as it stays on when being retriggered while the Reset-pin variant goes briefly off.

Using ARM-cortex-M0+,  tlc59116  and 74hc595.

We love IFTTT !

Since we discovered IFTTT, there has not been one single meeting where we did not mention it. It is paving the way of the Internet of Things as we want it. Easy, open, scalable, inventive…

Hearing that they just received an extra 30 million USD to further grow makes us happy.
