MOTM

I need 2 beta testers for the VC Pulse Divider prototype. Here are the 
*requirements* :

a) have a MOTM-950 supply or have one on order (which means I'll bill you and 
send it with the proto). OR...place an order for one :)

b) the prototype is *not* a 'module'. It is a pcb about 8 x 10 inches. It needs 
to lie flat on a surface (not dangling in space) within 24in of the MOTM-950. 
The jacks are pcb mounted along the 'edges' of the board. There are some 
switches and pots also soldered on the board.

c) Although you can run audio through it (up to about 14Khz) that's not the 
*primary* use. It's a "clocking" module that sits in-between say a LFO and a 
sequencer. The input can be any thru-zero wave, but the outputs of the divider 
are (currently) 50% duty cycle square waves of about 0 to +4V. I need testers 
that have 'things' with external clock inputs.

d) there is a 'stepped' CV output that is set for 4ths/octaves/5ths that you can 
drive VCOs, VCFs, etc with. Fixed at 8 steps, but driven by either the input 
clock or the /N clock (switch selected).

e) you HAVE to mess with it for some decent time by April 1st. And I don't mean 
"Oh Sh-t, Paul is going to call me tomorrow! I'd better *find* it!".


So, if you qualify please send me a *PRIVATE* email.

Paul S.

I Wish!

I'm building my 480s tonight and can't find any mention of Q3-Q6 in 
the instructions. Obviously, they go into the board, but is it 
recommended to have them thermo-coupled as Stooge Larry mentioned in 
a previous email?

Also, I'm wondering what other people think about these pre-populated 
boards. It sure saves time getting all the resistors and most of the 
caps installed. But it also seems a bit like having your food 
pre-chewed. Mmmmmm, baby food. I had a couple of resistors come lose 
along the way, so check your ziploc bags before you stuff your lunch 
into them.

Yes, add the thermal compound between each pair of transistors.

I'm with you on this. The time saving is OK, but I enjoy board stuffing. 
It is half the fun of building the kit and I find it relaxing therapy.

Actually, I like the prepopulated boards.  Yes, I enjoy putting together
the module kits, but populating and soldering the resistors (and the
decoupling caps) has always  been my 'least favorite' (to put it
mildly) part of building a module.  I vote for more prepopulated boards.

I'm definately in favour of pre-populated, anything that reduces the 
risk of wrongly placing a component is good news to me.

Hey, if you really enjoy placing the resistors and caps you could  
take them all out, mix them all up then place them back in again ;-)

Amusingly enough, my preferences are opposite: I think stuffing boards is
more fun than the mechanical assembly and running the board-to-panel wires.
That said, the presence or absence of a pre-stuffed board has little to do
with my purchasing decisions.

I think it's a great idea. Personally, building the modules is a distant 
second to using them. I'd happily buy all my boards pre-stuffed. If I 
could afford it I'd buy them already assembled, but I can't so I build 
every one. The point (for me anyway) is to make music, not inhale a lot of 
solder. I get my soldering kicks with my own personal projects.
