Trigger Fires Up
Well I finished the two prototype boards tonight with some minor changes and a bit of troubleshooting, still lots to do though. I now have them triggering. Will be testing further over the next few days to get indication of range etc. So far it is only syncing at 1/100. I will be posting more details [...]

SHT-15 Humidity Sensor
I couldn’t get any hands-on hardware development time for the Strobbit open triggr project today, so I designed a breakout board for the Sensirion SHT15 Humidity/Temperature sensor for my weather station I’ve been intending to build. I have a couple of these sensors at home waiting for something this so I can have a play with them. PCB uploaded for [...]

RFM12 FSK Library - Alpha Release
I’m pleased to announce the very ALPHA release of the RFM12 library for the wireless HopeRF RFM12 FSK tranceiver module that I’m using for the strobist open trigger project. It was developed under BOOSTC for the PIC embedded controller, but should be easily ported to any compiler.
Most of it is untested, hence the alpha release, but it’s a good [...]
