Figure 8. Ready to go; just install
some batteries and connect a set of
external headphones for testing
will be used for the MIC input on
the ChipCorder. Two connections
must be made to this input —
output and ground.
Schematic 1. The “Instant Replay” circuit.
Step 6. Power to the Circuit.
Attach a battery pack to the
ChipCorder circuit. If you are able to locate the new I1610
IC, however, you can drive the circuit straight off of the FM
radio main circuit board. Alternatively, you could use a
small coin-size 3V lithium battery for powering an I16xx
series ChipCorder. Install batteries in the radio and make a
sample recording. Now play back your recording.

Step 7. Looking for Mr. Brightside. If both recording and
playback check out okay, put everything back together
and start making some great song notes. At least now you
won’t look like an “American Idiot” next time you go to the
local music store. NV
