<ul>
<li>Try different kinds of paper, and pencils. Mechanical pencils are great, but require a little more work. Check <a href="http://www.drawdio.com/">drawdio.com </a>for more information</li>
<li>Place
a copper coin (like a penny!) on the drawing and use that to make
contact with the graphite - it will make the surface area larger and
reduce the resistance of the drawing</li>
<li>Hold hands with someone and 'draw' on their skin with the pencil</li>
<li>Wash and lightly dry your hands to make them a little more wet than usual, this will also affect the pitch</li>
<li>Use graphite slugs, available at an art store, instead of a pencil</li>
<li>Just hold on to both sides and try twisting and pressing to make different tones. </li>
</ul>

<div class="textblock"> <!-- InstanceBeginEditable name="text" -->
<p>The
Drawdio is simple to use. Simply grip the pencil in one hand so that
you're making good contact with the copper tape. Then draw a circle on
the paper and touch it using a finger from the other hand</p>
<p align="center"><img src="drawdio_t.jpg" height="254" width="500" border="1"></p>
<p align="left">This
allows your body to act as the sensor. The voltage is very low (about 1
volt) which is very safe. As long as you stick to the single battery,
there are no health risks.</p>
<p align="left">Using a copper coin
between your finger and the graphite will improve the conductivity.
Washing your hands and then drying them will also help, especially if
you have drier skin or live in a dry climate.</p>

<div class="textblockheader"> <!-- InstanceBeginEditable name="Header" -->Choosing a pencil<!-- InstanceEndEditable --> </div>
<div class="textblock"> <!-- InstanceBeginEditable name="text" -->
<p>The
'softness' of the pencil lead will affect how thick the drawn lines are
and thus the sound of the pencil. Experiment with hard and soft leads
as well as sharpening or blunting the point to see how that affects the
drawdio sound</p>
<p>Mechanical pencils also work well. However,
you may have to put an insulative layer (like packing tape) on the
lower section of the pencil if the body is completely metallic.</p>

<td valign="top">You
can mount the drawdio to your pencil. Place the PCB on the flat side of
a pencil, and thread the zip tie through as shown and tighten it.
You'll want it about an inch or less from the top of the pencil. The
higher it is the more pencil you'll have to sharpen but it may be a
little more unbalanced.</td>

<td valign="top">Next
cut a 1.5" piece of copper tape using the diagonal cutters. Don't use
scissors as the metal tape can damage them. peel off the paper backing.
The copper tape is conductive, sticky and flexible which makes it
perfect for wrapping the pencil</td>

<p>Then
take the thumbtack and gently push it into the end of the pencil. You
might have to twist it back & forth a little to get it all the way
in. The thumbtack will grip the copper tape and also make contact with
the graphite in the middle of the pencil to make the first half of the
drawing sensor</p></td>

<td valign="top">Next
take 3 or 4" of copper tape and start wrapping around the bottom of the
pencil, starting with the silver tab on the PCB and ending an inch
before the end of the pencil. This will make contact with your hand and
provide the second half of the sensor.</td>

insert a battery into the kit. Then grip the pencil with one hand and

<div class="textblock"> <!-- InstanceBeginEditable name="text" -->
<p>You
can also use a brush. We suggest paint or water with a little bit of
salt dissolved in it, to improve the conductivity. Since the brushes
have a plastic coating on the metal collar, you need to wrap the copper
tape around the <em>bristles</em> themselves, as shown here. Click on the photo for a larger version</p>
