For a long time I’ve carried test cards, ive had them in a variety of containers.
My latest is an adapted Pelican 910 Memory card case.
I pulled the memory card inserts out
Cut some flex tape to be the new base for top and bottom, since it sticks like shit to a blanket, plus is thin and malleable
I cut some holes in some thin foam for Hammy repeaters and detectors
More foam for some test cards
There will be some tweaks to come (i won’t bother sharing, because its boring), but you get the idea
