Subject: Re: I've done it : FM Recorder opened :-D
From: Andrew Jamieson (ajamiesn_at_optusnet.com.au)
Date: 2003-02-09


Although piccies are good, what we _really_ need is for someone to not only
take thier FM recorder completely apart, but then measure how the circuit is
connected, by checking continuity between each component and via with a
multimeter. This means literally measuring from one point on the PCB to
every other point to see if a connection exists. Unfortunately it's a
rather labourious and frustrating procedure, but there is really no
alternative.

However, it's interesting to see it uses two Li-Ion batts, but it looks like
they are connected in parallel ..... _very_ wierd. Very wierd indeed.
