AJ8T sent me the link to the web site of this, our latest Homebrew Hero. I don't think she is a ham, but Tatjana definitely has The Knack. Check out that workmanship. The range of the projects is also quite astounding. It is so impressive that I really found myself questioning whether this could be for real. But it is.
When you look at the Enigma-like coding machine, note the cryptological challenge at the bottom. Tatjana won't release the tech details of this project until someone cracks the encrypted Haiku! Go for it!
