Just had 182 and 186 WCR pieces delivered.  We will continue with the following numbering scheme:

TTT MYY-SSSS

Where:

TTT is the three-letter puck type: HV2, LAF, SAF, SH1, SHT, or WCR. Note that HV2 and SHT appear on tops only, and SH1 appear on bottoms only.

MYY is the month (M) and year (YY) in which the puck was manufactured. The month is represented by a number, 1 - 9 for January to September, or the letters, A, B, or C for October, November, and December, respectively. The year, YY, is represented by two numbers for the year.

SSSS is a four-digit serial number for the puck (0000 - 9999).

The following are examples of serial numbers:

SHT 410-1234 is a serial number for an SHT puck top that was manufactured in April, 2010 (410).
SH1 410-4321 is a serial number for a SH1 bottom that was manufactured in April, 2010.
WCR A10-1008 is a serial number for a WCR puck top or bottom that was manufactured in October, 2010 (A10).

Our current (July, 2014) puck count is here

Email from Scott, January 9, 2008 (updated 1-15-2008):

The current serial number format is as follows:
 
TTTRSSS
 
T = Type WCR (top and bottom), SHT (bottom), 1HV(top), S1V(top) LAF(top and Bottom) and, SAF(top and Bottom).
R = Revision/Lot code 0-9, A-Z
S = Serial number 000 - 999.  This number resets at each revision, lot change.
 
The previous Alkab run was Revision code 0.  We had a short set of about 5 of the snap puck made by El Camino which were engraved with the R field as 1, which means that the completion set should be lot code 2.  This is the set that Nilo is getting ready to send out now.  When El Camino delivers the first set of 40 in March they should have lot code 3 and the remainder should be lot code 4.
 
 
I have started a spreadsheet that chronicles the pucks, revisions, lots and serial numbers.
 

UPDATE (FEB 26, 2008)

 The first half of lot code 2 was returned with some Type errors.  Revision and Serial numbers remain unchanged, but the new Type designations will be:

WCR (top and bottom)
LAF (top and bottom)
SAF (top and bottom)

SH1 (bottom)
SHT (top)

Note that we have yet to make a full batch of high-volume snap pucks, but when we do, those will be labeled 1HV (top and bottom).

Here is who is doing our etching:

LaserMark
2109 O'Toole Ave. Ste S
San Jose, CA 95131
Phone 408 433-9333
Fax 408 433-9343

Here is what I have packed up for etching:

Type Top/bottom Numbered Amount NOTE
WCR Top 040-079 40

Bottom 040-079 40
LAF Top 040-078 39 1=Missing

Bottom 040-078 39 1=Missing
SAF Top 040-075 36 4sent to Gregg D

Bottom 040-075 36 4sent to Gregg D
SHT Top 080-159 80
SH1 Bottom 080-159 80





TOTAL

390



I also sent 1 WCR puck (top&bottom) as a font sample.  When these come back I will pack up the ones that are to be re-numbered(SHT2000-079).  I haven't received a quote yet but Laser Mark said about $2 each piece + shipping.

UPDATE 3/24/08

The SH1 tops that were misprinted are going to be sent out tomorrow to be re etched along with one of the LAF's that escaped detection last time:

Type Top/bottom Numbered Amount NOTE
LAF Top 079 1 Found the Lost 1!

Bottom 079 1
SHT Top 000-079 80 Old etching to be X'd out





TOTAL

82

That is all for now


UPDATE 2/24/09  There have been several iterations of the above serialization process since this was last updated. 

Here is where we now stand:

This is an inventory of pucks that have been serialized and are available for use. 


There are aprox. 1200 more pieces (or 600 more pucks) that have yet to be serialized.

They are located in the 'B' building lab














Type Top/Bottom Lot 2 Lot 2 Lot 3 Lot 3 Lot 4 Total
WCR Top 40 40 40 39 40 199

Bottom 40 40 40 40 40 200
LAF Top 40 40 40 38 40 198

Bottom 40 40 40 36 40 196
SAF Top 40 36 40 39 40 195

Bottom 40 36 40 40 40 196
SHT Top 80 80 80 80 80 400

Bottom 80 80 80 77 80 397
Total
400 392 400 389 400 1981 990.5







pieces pucks









The lot number refers to the 4th place in the serialization code: 
















3 letter type







1 digit lot number






3 digit individual part number











All parts are numbered 000-079 ( except where some are missing) for each lot EXCEPT for :
















SHT=000-159







SH1=000-159



UPDATE August 11, 2010

 Puck order from McLane arrived.

Rec'd  160 SH1, and 80 ea of LAF, SAF, WCR, HV (consists of HV top and SH1 bottom), all laser-etched.

Here is their email explaining their numbering system (sent Jan 14, 2010):

Subject: Puck serial number format

Hello All,

We've been thinking about the serial number format for the pucks and we'd
like to suggest some modifications.  I'm concerned about duplicating lot
numbers and the potential for having runs bigger than 1000 units.

At least for now, I think there's the possibility of McLane and MBARI still
continuing to make puck independently.  Keeping track of the current lot
number could be problematic.

So I propose the following:

TTTMYYSSSS

TTT for type code as below.

MYY for date code in
M= 1 - 9 for Jan - Sept, A B or C for Oct Nov & Dec

YY for 2 digit year

SSSS for serial number 0000 - 9999

Also, this ensures that there never a letter I or O.

This increases the total number of characters from 7 to 10.
