Well, I've spent the last few days and a good deal of cash on designing and laying out a new STM32F405 based NETMF board for an industrial control project I'm working on.
Just ordered all the parts, the PCBs (Hope DF Robot can make sense of them) and a shiny new IR reflow oven from eBay. It has cost a small fortune to get started, but the experience and functionality the board will offer, not the mention to savings on the next one will make the effort worth while. Thanks to my very understanding and patient mentor @Justin, for his endless enthusiasm and insight; wouldn't have wanted to do it without him.
Should have the boards back in 5 days (plus shipping) and then the fun will really start. Getting the firmware onto the STM, programming the BLE, playing with I2C LCB displays and EEPROM devices, oh and then there's the actual industrial stuff to do as well. Added to all that, a simple WP8 or WinRT app to interface to the BLE and we'll be good to go.
I'll keep you posted on my progress.
Wish me luck.
