If you have any interests in road network routing (tons of interesting topological problems there) we might be able to help each other out. This is where about 90% of my time is spent.

As for interests, however...

Feel free to get in touch with me to talk EDA and EE stuff as well. I'm presently a bit fed up with EDA usability, and I'd love to discuss ideas for how to move low-cost EDA away from "mspaint" and toward REPL.

I'm also very interested in building a tight-loop GNSS/inertial navigation system from scratch using an RF front-end (MAX2769) and a 9DOF IMU on-a-chip. I believe all current DIY inertial nav projects like this use absolute position output from an off-the-shelf GPS. I think by including inertial information during the signal processing phase it's possible to get accurate and precise absolute and relative positioning.

Along those same lines, I think it'd be cool to try to build a single-station RTK GPS by measuring carrier phase across multiple GNSS systems/bands. I'm not 100% sure how to go about this however, but I have a feeling it involves a tunable multi-band receiver or multiple single-band receivers feeding into an FPGA.
