Subject: Re: [EE] Wire wrapping insight needed!

Just to add my voice to the Cacophony, 

I've switched to making my own PCB's for prototyping and haven't looked back.  

I use the pulsar toner-transfer system that needs tape,  access to a
laser printer(or photocopier), and a clothes iron(you have bought one
by now, haven't you?).  a PCB can be printed and masked in 5 min. and
etched in about 10.

http://www.pulsar.gs/index.html

setup cost:

Toner-transfer paper:  $15 from digikey, mouser or . . . (+ ~$5 for shipping)
plated board:       $5.00 from radio-shack
Ferric chloride:        $5.00 from radio-shack
etching tray, sponges, gloves, steel wool, tape, skittles, and other
needed lab gear: $5-10

so for about $30-40 you can get up to speed and make your own pcb's
with a time cost of the artwork time +15 min.  At that point, if a
minor mistake is made, you kick yourself for five minutes, rework the
artwork for five, and recreate in 15, and you're back up and running
in under a 1/2 hr.
