Hi everyone. Not too long ago, I finished my master's project. The goal was to develop a small biofuel production system. I have been working with three other students (an EE and two MEs) and my job was to design and build a control system.
The design is based around a PIC18F66K22 microcontroller. The board has a switching power supply supporting an input voltages of up to 34V, five thermocouple channels, HD44780 LCD interface, a battery backed RTC and a microSD card slot.
The control unit interfaces with an electrical system (designed by my colleague) to control solenoid valves, motors and heating elements.
The programming was done in C and there is support for all the hardware except the RTC and microSD card.
If you want more information, my website (http://http://projects.armandas.lt/meng-group-project.html) has links to project report, schematics and source code.

I agree with Ian, a very cool looking board. Nice write up on your website

Thanks. To be honest, after writing the report, I couldn't be bothered to provide all the details on the website so just tried to summarise and hoped for the best.

again, nice work! i especially like the little Aavid Thermaloy SMD heat sink in the top right corner :).

Thanks for the correction, I wasn't aware of Fischer Elektronik.
