Hi folks, I was planning to organize a combination group buy / DIY for this forum. I can get parts from (among others) AJK's group buys and I can also build complete modules for you.
About me:
I live in the Netherlands, a part of the world where the Euro dominates. I'm a computer scientist with lots of electrical knowledge. I can at least design and build reliable drivers for you. One of the drivers I designed and which proved reliable is one with which I can continuously adjust the diode current, either with a potentiometer or an analog modulation input. With a friend, I am currently co-designing a professional microprocessor controlled driver with USB, laser data communication, modulation, LCD display and lots of knobs and features.
Now as for this action feeler, I am thinking of not doing for one or more of the following reasons:
If this action continues, I can at least build modules for very cheap prices, but they will not have the best build quality (unless maybe someone points me cheap metal flashlight hosts with quick shipping) On the other hand, I can also provide "Laser module kits" with all the electronic parts needed to build a laser, but not the mechanical parts (also no heatsinks).
Now, these are the prices at which I can get my parts:
I will also ask a small price for the labor involved with some parts, like extracting diodes from the drives or soldering the electronic components on a PCB.
These would be the prices of DIY kits and pre-built units:
DIY kits:
Modules:
To make sure the message is clear, I will only continue with this action if there are enough people which are willing to buy parts from me.

Now as for this action feeler, I am thinking of not doing for one or more of the following reasons:
- Bad euro->dollar rates
- High shipping costs outside Europe
- Customs confiscating stuff
- Average or above average prices for laser diodes (most expensive part)
- The plastic boxes I had in mind are crappy, and no flashlight host has been recommended to me yet (waiting for AJK on this)
- Heat sinking problems (both diode and driver) (RED's only)
- No precise measurement of output power (although I can calculate it with a detour)
