No empty Altoids tins around, but I did have an empty tin that used to hold some tea bags. It was the perfect size to hold the Softrock Lite II and a 9V battery.
Punched a couple of holes into the tin so I could secure the board and instant enclosure!
On the right side I think I’ll see if I can make a hole to attach a BNC connector for the antenna. On the left side I’ll make a small hole to run the cable out to the sound card.
