I bought one of these fabulous kits from Brewington Technology and thought I'd share it with you.

Shown here is what you get in the kit for $28.  (Leads not shown)

All of the components are very nicely laid out with a line showing exactly where they are placed on the circuit board.  It is very easy

to install them one by one without error. 

All installed and soldered minus the IC chip.

Looks factory like.

Installed speaker and switch.

Installed wires to board and placed board into case.

Neatly wire tied wires as shown in instructions.  Note: Install 9V battery before use  ;o).

All closed up and ready to use.  This case is designed to house the wires in this area neatly.  I just used a rubber band for now.
