Maybe someone is Europe has some.
2 words: Good luck
This is not the first time I have seen you rail on Andrew for having the audacity not to have a driver available on demand.
So here is my suggestion for you:
- First protoboard a driver, go through several revisions until you are sure that it can meet the specs that you have laid out and it is not going to blow up expensive sensitive diodes.
- Then layout a tiny smd pcb, get a test batch of boards. Then order small quantities of the 30+ parts for the board. Then hand solder the test boards. Then make any changes and repeat the process until you have a gold master board layout and schematic that you are happy with.
- Now you can make a pcb file for the board house and pannelize the boards for production. Also you have to generate a pick and place file for the board assembly house as well as order all of the components in quantity hoping that the price hasn't changed too much and the parts are still available. If there are any parts that are a problem go back to step 2.
- Spend a bunch of money getting boards and pay the pick and place house to populate your panels of drivers. Do any hand soldering of through hole parts (if applicable) then de-pannelize the boards. Now you have to test each board so when some noobie bugs you about the fact that your board doesn't work you know it is most likely a problem on his end.
- Customer support: Now you have a inbox brimming with questions, try to answer in a timely fashion. Repeat, ad nauseum. Deal with shipping and fixing boards that people despite your best efforts have managed to blow up a quite, un-blowup-able driver.
- Setup a little online store, get all of your shipping crap sorted and now you are ready to sell to the adoring public.
- Keep the price low enough so people don't bitch, because how dare you actually make any money on your effort.
Do all of this in addition to the other drivers that you have built and designed for the pointer dorks. Repeat steps 1 through 7 for each of the other products.
This alone is enough for a full time job. Now work a regular job and, oh yea, in your spare time, GET YOUR FUCKING PhD. You also want to try to have some semblance of life outside of adoring laser enthusiasts and filling your brain with knowledge or trying to pay for said activities. It might be nice to get laid one in a while, or just relax and have a beer, or both.
Doc. Andrew doesn't OWE you, me or anyone, anything. Instead of bitching you should be thankful that he has a masochistic streak for building well built, and very affordable laser drivers and other laser products for a tiny and fickle audience.
I guarantee that he is not going to retire on your driver purchase. In fact I would be willing to bet that if you look at it in a strictly business sense the entire endeavor is a net loss. He does it because he wants to, not because he is getting rich. I don't see Coherent making a 3 amp 100khz analog tiny diode driver for us laser enthusiasts.
He will have more drivers when, he has more drivers.
If you need a driver right now then go here and cut the poor guy some slack or do it your self.
