[tech] [committee] Wire wrap and other prototyping

[Bob Adamson]

I'm unsure why this was only on committee so I'm cc-ing to tech...

UCC does indeed have a wire wrap tool, though it's a simple hand one like 
this: http://www.aeroconsystems.com/electronics/wire_wrap_tool.jpg
Having never had all the equipment to do wire wrapping, I can't vouch for 
its effectiveness. I think the one we had many years ago got stolen with our 
toolbox in 2009.

Any chance this talk could happen on a weekend or as part of a sunday 
hackathon? I'm pretty keen to attend and/or organise it, but weeknights are 
a pita for me.

Hi Sam (etc)

Can do. What date ? A calamity is that the little adaptor boards I have been
using (SO8, SOT23, etc to DIP8) are discontinued from SoanarPlus. I'm just
finding out now what is available.

Manufacturer is Bellin Dynamic Systems:

Ok, Mouser still has them:

If you let me know the stepper driver chip package you were using (was it
TSSOP28 ?) I can get one of those from you and set it up on an adaptor board
(if available) to show a different approach rather than soldering to the SMD 
legs.

All the best
Harry
