The steps involved in building a kit are listed below. Be sure to fol ‐
low them and you will have a lot of fun building, aligning, testing
and using your kit.
1. Do a parts inventory . Check off each part in the parts list to be
sure you are not missing anything. Our method of bagging parts is
different from all other kit vendors and will make the task much
faster and less error prone. But despite our valiant efforts, mis ‐
takes can happen. If you are missing any parts, call or email us
and we’ll rush replacements to you immediately.
2. Do not remove parts from the bags until called for, to avoid mixing
parts up.
3. Pay attention to soldering techniques . Keep your soldering iron
clean by using a wet sponge, use appropriate heat and maintain heat
long enough to make good solder joints. Solder problems are the
number one cause of problems when building electronic products (not
just kits!), so try extra hard to do it right.
4. Take your time ! We know you want to get it done and start using it,
but doing it wrong will only delay that moment. Before you start,
set up a ventilated, static ‐ free work area with enough room to
build the kit. Prepare parts bins and get the tools you will need
(needle ‐ nose pliers, wire ‐ cutter, wire stripper, Phillips head
screw drivers, wrenches, soldering iron, solder, insulated tool,
awl or other sharp ‐ ended tool, scissors, magnifying glass, etc.) If
you’re tired, take a break. Enjoy building your kit!
5. Make sure that you are loading the part that’s called for in the
right holes. Once loaded, it can be hard to find a misloaded part.
Be especially careful to load polarized parts (ICs, transistors,
diodes, electrolytic capacitors) the right direction. If you are
not sure about any step, call, write or email us!
6. Once you’ve done a step, put a checkmark inside the parentheses.
7. After you have assembled a circuit board, take a moment (just one)
to marvel at your handiwork, then spend a few more minutes critiqu ‐
ing it! Check for solder bridges, unsoldered or insufficiently sol ‐
dered connections, solder blobs (especially on insulated magnet
wire used on toroids), loose screws and electronic parts, reversed
polarized components, etc. Sometimes it helps to have a friend
check your work.
