Post by: Audacity on December 23, 2009, 08:20:33 AM

before you read this board it might be beneficial to read this http://www.societyofrobots.com/robotforum/index.php?topic=9888.0 (http://www.societyofrobots.com/robotforum/index.php?topic=9888.0) Well as you know im building the $30 or less microcontroller (BS2sx) and when looking for the 2N3904 NPN transistors and 2N3906 PNP transistor i kept getting dead links :( also whats a 9 pin female connector and 10uF cap capacitor? finally my last question is when picking out my resistors what wattage should i use i doesn't say in the tutorial?(http://www.societyofrobots.com/member_tutorials/node/26 (http://www.societyofrobots.com/member_tutorials/node/26))

You might try Mouser for parts. Here's the 2N3904:

The resistors shown in the tutorial that are plugged into the breadboard are 1/4W metal film.
Any of these resistors will work:

Here's a good link to Jameco, the one in the tutorial is broken:

Good luck and have fun.
