>>Remind me how wonderful a 80 resistor *L F O * is again....<<

My thumbs got sore just doing the lead bending for my two LFOs.  Not to 
mention the amount of wasted time it takes to bend resister leads one at a 
time for 10 modules at once.  Isn't there some kind of device I can just drop 
the resisters in, turn a crank and have it spit out resisters all nice and 
ready to insert?  I have seen in the past, resisters that are pre-bent.  Why 
doesn't Synthtech use those?

>>...while I soak in a salt bath and dream of high-powered model rocketry:

Is it just me, or do others think Paul has too many side interests.  As 
customers, I think we should demand his attention be paid to Synthtech 24 
hours and day, 7 days a week.  Or at least until he gets the damn Mixer 
module done ! :)

BTW, something I wanted to do years ago was develop some kind of guidance 
system for a model rocket and write the software to guide it.  But I have 
heard that it is illegal to put a guidance system into model rockets.  That 
kind of takes the fun out of rocketry.

I believe the term your looking for is Missile!!!!

In respect to lead bending, this is something I have had a look at, due to a
degenerative joint condition.  Bending 5 - 10 resistor leads then having to
take a break is a tad frustrating especially in the 320 LFO.
The hand crank component lead benders are expensive, here in the UK, both
Farnell and RS stock them. But If you are not forming components by the
thousand probably a bit over the top.

I went for a hand operated device, which Farnell stock and is made by ABECO
and called a Forming Handtool, you can also get versions that crop the
leads.  Most of all they are not that expensive, approx 35 UKP.

Now when a new module arrives, I just adjust the alignment points to the
width of the holes in the PCB and "Bend Away".  Forming the whole bag of
resistors in one go also stops them rolling off the bench when your looking
for the elusive value.  Well worth the money.  Oh yes it also exercises your
hands ready for the stunning keyboard run when the module is ready.

Thanks for the info.  And a version that crops the leads sounds even better 
still.  I like to stuff the PCBs with all the components that lay flat on the 
board for the first pass, like resisters, diodes, ceramic caps and ferrite 
beads.  I need to clip the leads shorter, otherwise they get in the when I 
try to solder.

Too bad Paul doesn't invest in that and save himself and all of us a lot of 
time.
