UPDATE - no Krytons but MXDL instead Changes marked in red
UPDATE 2 - selling 7 kits Changes marked in green
UPDATE 3 - All parts except for the MXDL hosts from DealExtreme have been received. Payment started for people on the list (see below)
[highlight] [/highlight]This is how I will do this now. I will let the people on the list choose what they want (which kit, or backing out). I'll PM the first person. If he responds, I'll scrap one kit and PM the next. If this person does not respond within 72 hours (3 days), I will move that person one position down on the list and PM the next person in line, and so on. Not-responding persons will keep flowing down on the list until they respond or when all kits are sold.[highlight] [/highlight]
This is a sale feeler for DIY building kits consisting of everything you need to build a reliable powerful violet laser for yourself. There are 10 different kits specifically tuned for the individual differences between the violet diodes. Available power ranges reach from at least 100mW to possibly up to or over 200mW!
The laser will have no duty cycle because of the supreme heat sinking capabilities of the Kryton Groove (Kryton 2) barrel. There is only one thermal contact area, that is where the diode is pressed in the Kryton head. No Aixiz or other kind of module is involved. The lens is an Aixiz acrylic lens which screws directly into the Kryton barrel. (glass lenses are discouraged as most have a coating which blocks part of the violet light)
The flexdrive from drlava will get the most out of the batteries. Battery life ~2:40 hours! (at 150mA)
Only a soldering iron and at least one right hand are required to build this.
This kit consists of parts gathered from group buys and discounts, so you don't have to do buy the parts yourself. [highlight]Some of the kits will even be sold below cost price![/highlight]
They will be sold at an average price of $ 97.20* (ex. shipping) (old price was $ 97.04)
* See price breakdown, below
Package contents
The kit will consist of the following items:
*It is possible to get a harvested diode for $4 extra. (First harvested one for free*)
Due to the measuring process, I have to harvest the diodes and put them in the Aixiz. See this post.
Please note that the batteries have changed to NiMH types!!
The average price of this kit is far below any completely built violet laser pointer out there, and they will never compete with a real Kryton in built quality.
Price breakdown
These parts can all be bought separately from different sources. The following table lists the cheapest prices I found for single units (incl shipping):
I will be offering these items for the following average prices:
Individual power, individual price
I will be offering all seven kits at a fixed price per mW ratio. This means that if the average price is $ 97.20, the lower powered units will sell below cost price and the higher powered above that. The total cost off all units (7*97.20 = 680.40) will be divided amongst the kits with weighted ratios.
The following list shows the mW and price of each kit:
(Price/mW = 680.40/928mW = $ 0.733/mW)
1. 90.5 mW $ 65.81
2. 112.2 mW $ 81.59
3. 115.8 mW $ 84.20
4. 137.1 mW $ 99.69
5. 154.4 mW $ 112.27
6. 155.0 mW $ 112.71
7. 170.7 mW $ 124.13
Total:
928mW $ 680.40
Note that the most powerful ones are even more expensive than than buying the parts separately, but I will have tuned the diode to this powerful setting without endangering it. If you buy these parts yourself, then 1) chances are great you will receive a less powerful violet diode, and 2) if by chance it is powerful, you'd probably have a hard time finding the maximum allowed power without endangering it.
Remember, this is just an example, and they are not real measurements or prices, just an indication of how I will calculate the prices by the time I do have the real measurements.
Shipping & handling
Shipping costs are as follows:
Europe - $ 6,50
World - $ 10,80
Paypal fee: 3.4% of the total price plus $ 0.54.
How, What & When
I will start this thread as a feeler, because I don't even know if there is a lot of interest in this sort of thing. At the moment I don't have most of the parts, and when I do, this thread may be converted to a real sale thread. It is not yet possible to reserve a kit, as the laser powers are not known yet. It is however possible to reserve a spot, so that when the kits are available, you'd be the first to choose one. (like a queue). <- old information
My laser diode supplier is amkdeath(who is in Iran at atm). When I receive the laser diodes, I will start measuring them, and a few days later I will have the measurements online, and the ordering (committing) can begin. As measuring the diodes requires me to at least harvest one out of the sled, I will sell the first person who orders a harvested a $4 discount (ie. no harvesting costs). Experienced users, please keep in mind that there is always someone who needs harvesting more than you! (btw, harvesting is very easy, unless you have two left hands, in which case you shouldn't buy a kit) <- old information
When the Kryton barrels are done and sent to me (likely not before half september, according to Kenom), I will start shipping. If there is not enough interest before this time, this will be canceled. <- old information
Because there is a real possibility that I will have less than 10 working laser diodes left after testing, I will sell as much as I can, at the same prices. See the link below about the bad quality laser sleds I received. I've also merged the two lists of interested people.
I've ordered the batteries, Lavadrives, heatsinks from Jayrob and the hosts from DX. I guess the bottleneck will be DX so after I receive those I can start compiling the kits.

Afterword
Daguin once said, "be prepared for some stiff competition in the forum. Out in the world, people will buy them, but on here, you've got to do something "special." If you guess wrong about how "special" you idea is, you end up with lasers sitting on your desk waiting for the next rock show or you run a "fire sale."". Well, I hope this is considered "special", as there are a lot of people out there wanting to build one as opposed to buying a complete one. And with this they get the change of not only building one reliably, but end up with a high quality pointer that looks great and lasts!

But I decided to register once I saw this thread just to show some interest in this little project. Personally, I think it would be great to have a DIY kit as a first (or even as a first project) to help along with the understanding of how to do projects like this
