John, Et Al,
I am reading some really good ideas. Here's one I used...
While building my KX-1: When I conducted my inventory, I taped the
resistors, inductors and capacitors right to the pages of the book.
Okay... A little funky, but 1) I knew the inventory was correct when I
was done
Tape - cardboard - plastic - paper - A
My ESD training (what little I've had) is causing all sorts of alarm
bells to go off! I fear that many of us have taken techniques that
worked fine in the pre-ESD days and are applying them in cases where
they are dangerous.
Yea, I know that caps
Tools I found useful:
- Magnifying ring light
I far prefer an Optivisor. It makes it easy to look at the item
in question with or without magnification, depending on distance -
I can position the workpiece and the instruction manual such that
I can shift my view from one to the other without
Keith,
You are, of course, right, but 1) I do have an ESD mat (and use
it!), and, 2) no, I didn't tape down the sensitive components. I will
say this though: Doing this helped a lot because there are several
components that could have easily been confused (some inductors and a
resistor or

From an ESD point of view, that's cool, but when you pull the tape away
from the paper, you're generating a static charge which may make it to
your 1/2 populated board and cause problems
It rarely happens because a lot comes into play, humidity, proximity of
certain clothing, walking on carpet,etc. If Humidity is up around 60% or
higher,
not wearing wool or synthetics, and not a lot of foot traffic on the wool
carpet next to your workspace, you have probably nailed down

Good light
Magnifying glass

Negative lock tweezers (big ones do not send parts flying)
Good Multi-meter

Capacitance meter - not required, but it helped me

Yes, plastic organizer boxes did help. In the craft section at
Wal-Mart. Sorted and inventoried parts and put caps, diodes, resistors
in one, and misc hardware in the other. Helped out quite a bit.

John,
Congratulations on your decision.
Equip yourself with a set of flush cutters if you don't already have
them - while diagonal cutters will be OK for the K2, flush cutters are
required in a few areas of the KPA100 and several other options -
overall they make a neater finished product.
Rework Eliminators - They're great provided you are willing to spend the
time to make sure they get installed right. They represent a departure
from the normal build process and if you mess things up, then debugging
may be tougher. I went with them, and was careful. I had only one bad
solder
Just a comment here - keep the ICs and transistors in their black foam
(or pink plastic bags) ESD safe holders. Remember that many plastics
can build a static charge. I suggest that you ignore any thoughts
about sticking the components into styrofoam - that does generate static.
As another
pull it out of the tape.
Good luck.

John,
Everyone has great ideas. Here are mine. I like the visor as well. I got one
for five bucks. Very good to have. I also use ice cube trays (Plastic) for a
parts bin. Sometimes things do not fit will, but it does work quite well. You
can use muffin tins as well, but I would not

Congratulations on your decision to build a K2 with your son. I concur with
the advice you are getting about having good lighting, ESD protection, vice,
etc.
If you don't already have them, I think a great way to introduce your son
into the kit building process would be to have him build the

Perhaps it deserves saying the obvious: DO NOT USE FOAM CONTAINERS FOR
ELECTRONIC PARTS!! (Unless, perhaps, you're working with vacuum tubes G)
Expanded foam in any form is a wonderful static generator. It doesn't take
enough static to see or feel a spark to destroy parts, only enough to exceed
Egg cartons for trays

You can get ice cube trays at the Dollar General Storeor other small
plastic containers as well.

My son is 14. He has gone with me to help setup field day. He
currently has the furthest from home contact. I am building my second K2
(K2/100 when done). I bought the DL1 and XG2 from what I learned from the
first K2. I supervised my son as he built the mini-modules. He saw the

Thank you all for the comments. A rough summary includes:
- Think ESD for the parts (no worries there... I am the ESD promoter at
our electronics lab at work)
