Handy hand tools for networking objects.
1 Soldering iron Middle-of-the-line is best
here. Cheap soldering irons die fast, but
a mid-range iron like the Weller WLC-100
works great for small electronic work.
Avoid the Cold Solder irons. They solder
by creating a spark, and that spark
can damage static-sensitive parts like
microcontrollers. Jameco ( http://jameco.

10 9-12V DC power supply You'll use this
all the time, and you've probably got a
spare from some dead electronic device.
Make sure you know the polarity of the
plug so you don't reverse polarity on
a component and blow it up! Most of
the devices shown in this topic have a
DC power jack that accepts a 2.1mm
inner diameter/5.5mm outer diameter
plug, so look for an adapter with the
same dimensions. Jameco: 170245 (12V,
1000mA); Farnell: 1176248 (12V, 1000mA);

5 Mini-screwdriver Get one with both
Phillips and slotted heads. You'll use it all
the time. Jameco: 127271; Farnell: 4431212;

2 Solder 21-23 AWG solder is best. Get
lead-free solder if you can; it's healthier
for you. Jameco: 668271; Farnell: 419266;

6 Safety goggles Always a good idea when
soldering, drilling, or other tasks. Spark

7 Helping hands These make soldering
much easier. Jameco: 681002; Farnell:

3 Desoldering pump This helps when you
mess up while soldering. Jameco: 305226;

11 Power connector, 2.1mm inside
diameter/5.5mm outside diameter You'll
need this to connect your microcon-
troller module or breadboard to a DC
power supply. This size connector is the
most common for the power supplies
that will work with the circuits you'll be
building here. Jameco: 159610; Digi-Key

8 Multimeter You don't need an
expensive one. As long as it measures
voltage, resistance, amperage, and con-
tinuity, it'll do the job. Jameco: 220812;

4 Wire stripper, Diagonal cutter, Needle-
nose pliers Avoid the 3-in-1 versions
of these tools. They'll only make you
grumpy. These three tools are essential
for working with wire, and you don't
need expensive ones to have good ones.

9 Oscilloscope Professional oscilloscopes
are expensive, but the DSO Nano is
only about $100 and a valuable aid
when working on electronics. Spark Fun:
