<DIV><FONT face=Arial size=2>so i've built charlie lamms modified version of
this which uses 2 transistors to deal with the gate.. i
think.. having a slight problem with it.. if
i apply a gate signal, no change, just high output.. if i apply the
gate at the output of the first transistor, it will go up, and at the
output of the 2nd it will go down.. so something is awry in that first
transistor stage i belive.. i've tried a different transis, and checked my
wiring 2 x.. any ideas whats wrong with it? his circuit
is here: </FONT></DIV>

<DIV><BR></DIV>
<DIV><FONT face=Arial size=2>Just messing around with the attached circuit
over here.. it seems to give a more desirable range when i present
12v on the gate.. how can i mod this to accept 5v?
</FONT></DIV>
<DIV><FONT face=Arial size=2>i've tried a few experiments with a transistor
(which i'm almost positive is the answer), but i don't know enough about them
to make it work.. anyone, anyone? </FONT></DIV></BLOCKQUOTE></BODY></HTML>
