How do you think you messed up the HDMI, break a connector on the board? I haven't gotten the heat sink kit for the Pi 2 yet. I've been thinking of making one out of scrap aluminum.
Connector seems fine, might have been due to hotplugging, or some software bug.
I used an old gpu-vram coolblock for the cpu, will take picture in a bit
Edit: here's a (quite blurry) picture.
Edit2: I'm getting quite nice coverage with the dual receivers now, tracking flights from Amsterdam Schiphol Airport, up to slightly further than Brussels =]
