>All,
>    A co-worker of mine was cleaning out his garage and gave me a bunch 
>of surplus DC motors he didn't want to keep.  Here is what I have if you 
>guys are interested.  Most appear to be brand new and still in the 
>packaging.  I'll bring them to the meeting for cash or swap:

>QTY  DESC						ASKING
>10   Hitachi permanent magnet motor with tachometer     $12.50/ea.
>     Shaft is about 5/16" diameter with two flat sides
>     36 VDC, 1.1 Amp, 2450 RPM
>     Has a 5 wire connector for tach (5V/GND/2 o.c. outputs/shield).
>     Has a 2 wire connector for motor (36V/GND).
>     Has a 2 wire connector for what I think is a 
>     thermocouple in the tachometer casing.
>     
>20   Namiki high efficiency DC motor                    $1/ea.
>     Shaft is about 1/16" diameter with 2 leads.
>     I think this is a 0-3V or 0-5V DC motor.
>
>10   Matsushita 12VDC motor                             $1/ea.
>     Shaft is about 1/16" diameter with 2 leads.
>
> 5   TEC Stepping motor                                 $2/ea.
>     Shaft is about 3/16" diameter with 5 leads 
>     (single common and 4 coils).  3.6 deg./step
>     Mounting screws built into case.  By the part number, 
>     this may be a 12V steper.
>
> ?   Few other misc. motors.                            make offer.
>
>Also on the trading blanket, from my own stock, is a Matrox MGA PCI/2+ 
>upgraded to 4Meg. VRAM.  I don't need it any more because I had to 
>upgrade my video card to one supported by X Windows under Linux.  Comes 
>with a manual and driver software.  Price/trade is negotiable.
>
>On a seperate note, I won the Richochet RC car a couple of months ago as 
>a door prize at the DPRG meeting and after cleaning it up and looking 
>over the board, it appears that one of the H-bridge MOSFET's has burned 
>out due to getting wet.  The part number is A1357 and I think it is a 
>P-MOSFET since it is connected on the VDD leg of the H-bridge.  I have 
>looked in several parts catalogs and www sites but have not found a 
>replacement part or cross-reference to this number.  Does anyone in the 
>group know what this part is or where I can get a replacement?  As I 
>recall the DPRG gave two of these cars away.  Maybe whoever has the other 
>one would be willing to part it out for one or two of my motors.
