Finished first prototype engine control system

I've been quite busy at work lately, finishing the first prototype for the CHASE-10 engine electronic control system, which is the main reason for the lack of blog posts lately. I've now finished the first prototype. It performs a real time data acquisition and signal processing on up to 42 analog input signals. One of the main requirements was engine health monitoring, so it performs Fast Fourier Transforms (FFTs) on up to 20 input channels, at a maximum sampling frequency of either 20KHz or 60KHz. The FFTs will be mainly used to monitor the pressure sensor and accelerometer signals. The system also incorporates an end-to-end simulation mode.
We're now thinking about making it a commercial product. In the near future I'll be taking some photos and putting them on the website to announce the product officially. I'll put another post on this blog as well, to let everyone know.
My next development task will be improving the real time data transfer rate to a remote PC so that it can have a secondary role as a data acquisition system in our test facility, and building the next prototype which will use custom PCB's instead of development boards; - plenty to keep me busy over the next few months.
