Miniboarders:

I am going to go ahead with a parts buy.  These kits will be WITHOUT A
PROCESSOR.  I still can't get a good solid lead on the E2s.  If something
good comes up I will distribute the info and MAY organize a group buy for
the processors.

For PC boards, contact Greg Ratcliff at gratclif@ohio-state.edu.

The kits will contain everything on the "Miniboard Parts Listing" down to
the start of the "Miscellaneous" section.  Under "Miscellaneous" and
"Sensors" they will contain:

	1 8 MHZ resonator
	2 inductors
	1 2N3905
	1 piezo beeper
	1 power switch
	1 modular plug cable	

	2 male strip header connectors
	2 reflective IR sensors
	2 phototransistors


The choices were made based on what was available from suppliers already
being ordered from.  The C-cell holder was left out because it is readily
available, bulky for shipping, and everyone might not be using C-cells.

I believe these are all of the parts on the board itself (except the uP)
and a few others.

CHANGE:  The L293D will be replaced with a L293E because Mouser has the
         L293Es.  I'll double-check, but I'm sure they're compatible- the E
	 has some protection diodes built-in, but may have less current
	 capacity.

COST:    Each kit will be $46.  This will include shipping via US mail.
	 I've estimated this price to cover parts, shipping (to me), 
	 shipping (to you), and packaging.  There is no intended profit (or
	 loss!).

WHEN:    NOW.  I will be ordering parts tomorrow (4/7) at around noon.  I
	 am as anxious as you to get soldering!  I will order parts based
	 on good-faith commitments rceived by 11:00 or so tomorrow.

HOW:	 Send me your request(s) ASAP to wrb@ccsitn.att.com (or reply to
	 this post - it will be forwarded).  Once I confirm, send a check
	 or MO.  I will wait for checks to clear.  I will be shipping
	 within 2 weeks (probably quicker, but I want to leave some slack
	 in case I get buried or something comes up).
