(If the above link has been deleted by eBay, please let me know and I'll include it with the PCB.  Unfortunately eBay doesn't allow me to post the link or ask you for an email so I can send it to you.)

This auction is only for the bare printed circuit board.  It does NOT include any of the electronics components, housing or oscilloscope.  I have the housing available separately on another listing in either Yellow or Green (depending on the oscilloscope you have).  I will send a link with the PCB that allows you to order one set of the parts necessary from Digikey (except for the battery cells).
