Re: (Wanted) detailed instructions Lavadrive + 803
The other way to do it is like this nice diagram that rog8811 showed:
http://www.laserpointerforums.com/forums/YaBB.pl?num=1197651171#1
Notice that the DMM is in line on the positive lead. You don't really need the 1 ohm resistor. Just set your DMM to read mA's.
For a blu-ray, use 6 silicon diodes in series. Notice in the diagram how they are set up... positive/negative. I compared my dummy load with a dim/dead blu-ray diode as a load. They both showed the same current.
Here's another tip for you if you are doing the 803T/FlexDrive build... Depending on the host/battery supply, you may also need a silicon diode before the driver. The max input current for the FlexDrive is 5.5 volts. Take a close look at this post by drlava:

In that post/thread, he also talks about and shows how the case pin on the LD, can be soldered together with the negative pin if needed...
