As you may or may not know Dr. Lava's microFlexdrive V4 will launch in the coming week. My question to you is what do you use for a test load (links please) or do you just pay the extra few dollars for him to set it?

I appriciate any knowledge gained from your replies,
Pyrostic

Same test load as with other drivers...

Use rkcstr's test loads if you can get them:
http://rkcstr.nfshost.com/

Get one for red, and one for blu-ray. They are very reasonably priced. If he is out, Greg might have some. (Stonetek.org)

You can also make your own test loads using silicon diodes in series. Use 4 for a red test load, and 6 for a blu-ray. See this diagram by rog8811:

Use it the same as with other drivers. The test load mimics the diode, so it can be used for what ever driver you are setting current for...

Great, one last question though. When placing batteries into my host do I want posative facing the driver or away from the driver.

That depends on how you set your build up...

Most of the time, the flashlight hosts are set up for a case negative build. Usually a tail cap switch, meaning the host case will be either negative, or positive, depending on which way you put the batteries in. On 99% of the blu-ray and red builds, the heatsink is making contact with the host, thus the diode case is touching the host. (in effect). With a red build, the diode case is the negative contact or pin. So you better have your build set up as case negative, unless you isolate the module.

There are a bunch of tutorials for different things like this in the 'tutorials and help' section, right at the top of the section...
