I need a variety of conditioning circuits for the fuel tanks and fuel pressure. I designed up a quick schematic. While I was at it, I added a circuit for a high pressure sensor for the oxygen system. This will let me feed the O2 level into the GRT.
I couldn't get my PADS software to reinstall correctly, so I switched to FreePCB. I am pretty happy with it - it seems more intuitive and up-to-date. And, free is good. Maintenance on PADS was costing about $750 a year. That's a lot for the small number of boards that I do.
I learned the package via their tutorials and then layed out the conditioning circuit board. I ordered 3 PCBs from Sunstone for $50 - quite a bargain. They are slow (but cheap). It will take a couple weeks to get them, but I have plenty to do in the mean time.
