I built a 40m CW transceiver Rock-Mite 40 of Small Wonder Labs in October 2010.
As of May 2015, we can get Rock-Mite series kits called 'Rockmite ][ ' from a successor QRPme

I bought the 7.015MHz version, and I changed the crystal to 7.000MHz in order to tune up the frequency of the crystal oscillator 7.003MHz.
I used an aluminum case Teishin Electric TC-103(W65×D85×H20) in order to make my Rock-Mite 40 microminiature size.

C7, C9, C103 are smaller size electrolytic capacitors

C7, C9, C103 are smaller size electrolytic capacitors,
because there is only 11mm from the PC board to the cover.
