[arm-allstar] Market for pre-soldered usb fobs????

[David McGough]

Hi again,

I've gotten some personal e-mails with questions, so, I thought I'd 
few more comments, as food for thought.

For hams wanting to develop proficiency in surface mount work, one method
is using old garbage PC computer (or any other) surface-mount boards as a
place to "practice." ....So, you gain some proficiency without risk of
destroying new hardware, fobs, etc.
