This was one of my first successful electronics projects a few years ago. It’s a TNC-PI from Coastal Chip Works. It’s basically a packet radio interface that sits on top of a Raspberry Pi. I built this thing several years ago and managed to digipeat a few signals off of the ISS as it passed over. I’ve always wanted an enclosure for this thing so when I found a design it helped push me over the edge in buying the 3D printer.
I can’t remember where my packets were gated out but I did manage to log the first ISS packets received on this thing. May 30th 2014

I’m printing a holder for my soldering iron tips at the moment and I might kick off a print of a BitX40 case this weekend. Hopefully I can find some time to do some soldering between now and then!
