It&#8217;s my first electric toothbrush ever.

I wish I could say that I&#8217;ve tried it yet, but the recharging connector stole my attention.

Notice that there are no metal tabs anywhere on that cradle connector?  The toothbrush is rechargable.  [...]<script type="text/javascript">SHARETHIS.addEntry({ title: "The Mystery Connector", url: "http://www.electrolund.com/2006/04/the-mystery-connector" });</script>]]></description>

The thing has been my trusty friend for many years, allowing me to go far beyond the recommended 2-3 weeks between haircuts.  A little neck trim, maybe the sideburns, no one would ever notice.

		<description><![CDATA[Why buy a $20 AC outlet tester, when you can build one for free?
The parts necessary are:

1 - old AC plug. I got mine from an old power cord.
3 - 100K Ohm resistors in parallel. This keeps the power dissipation down so they don&#8217;t get hot.
1 - LED. I chose red, size T-1 3/4

As with all boring mirrors, you have to manually flip them up when there&#8217;s bad headlight glare from cars behind you at night. And there&#8217;s no built-in compass!
