Soldering Class this Thursday Dec 4th 4:00pm

The next electronic construction class will be at the
Chippewa Falls library on Thursday, December 4th from
4 to 7 PM.  The location will change from the small
meeting room to the large meeting room.

Please read the following beforehand:
   “Learn to Solder – Tools and Techniques” (entirety, 35pp)
   “Elektor – Desoldering” (entirety, 2pp)
   “Winstanley – The Basic Soldering Guide Handbook”
     (pp. 1 – 80)

Before the meeting:
   Practice desoldering the scrap PCBs and soldering
   components back onto them.  The object is to produce
   clean, shiny joints like those on page 49 of Winstanley.
   Remember that good joints result from a clean soldering
   iron.  Clean the tip before each connection and
   particularly before reuse after desoldering a component.

Agenda for the meeting:
   Build or complete the multivibrator boards
   Test the multivibrator boards, troubleshoot and
     repair as necessary
   (Multivibrator operation and theory can be readily
     found on the internet – we won’t spend time on this)
   Begin a new project, depending on how well the PCB
     soldering is going; if all is well we will start the
     variable power supplies.

If anyone is lacking hardware which should be in their
kit please contact me so that I can bring it along.
