It is lots of fun to build and experiment with simple circuits. The way you designed the board suggests that you had a purpose in mind for it.&lt;/p&gt;&lt;p&gt;&amp;nbsp;&lt;/p&gt;&lt;p&gt;John&lt;/p&gt;&lt;img src="https://community.element14.com/aggbug?PostID=6033&amp;AppID=216&amp;AppType=Weblog&amp;ContentType=0" width="1" height="1"&gt;</description></item></channel></rss>
