O-Like Br Driver for lowpower 445nm?

http://omf.gd/bsp

Will it be suitable at driving an Casio Diode with low current?
As it can output 250mA and the Threshold is around 200mA
But it's output voltage is 4.8V - do i need a Diode for drop to 4?

Yes I have 10 of them in the works.

Great. do you use something to drop the output voltage?
As i read 445nm requires ~4V

Do they keep lasing around Threshold stable?

Notice the part about the multi-turn pot.

I am using normal batteries.(3xaaa) I am going to market the kit as "no exotic batteries needed" and see if I have any bites.

Just bought a large lathe so I should have the parts turned out this weekend.

EDIT: here is the host I am using. I have like 30 of these. Post #11
