Hey guys..
I ended up getting another quote from another local place., and this time, it looks much more reasonable.
This time, I can sell these kits for $80USD cheaper, making a complete kit as pictured $210USD. If the machined lid is not required, we can bring the price down to $190USD
Do we have some interest now? Think blue anodising!

Hi, my interest has rekindled but still worried about a few details.
This might be due to drawing interpretation.
TEC (Peltier and controller supply) ? (($15 from digikey didn't get me anywhere without more info).
Space behind diodes for Laserbugs ?
Space for driver board
Only one prism pair so no slow axis correction ?
Thermistor hole under knife edge adjustor not under diode mounts ?
Prism fixings ? (If glue then why mounting slots, not holes on prism table ?)
Cheers

Hey,
Ok, to answer your questions.
I have designed the module with digikey part number 102-1677-ND in mind. Its a 30w TEC, 8.6V 6A. As for tec drivers, there is the Dr Lava driver I believe, also the Die4Chill.
I doubt there would be space for laserbugs. I had trouble keeping the module as small as it is.. A hardwired connection would be my choice anyway.
There is a opening for a DB9 on the back of the module. If the user wants to squeeze the driver/TEC controller into the module, there is probably enough room, other wise it can be external.
Yes, only 1 prism pair (the updated drawing shows one of two clamps to hold the prism pairs in place ) Im not sure 2 prism pairs are really needed..
The thermistor hole has been moved, and is pretty much centred under the diode blocks. This will suit proportional ( like the die4chill ) You will need to mount the thermistor as close to one of the diodes as possible if using PID.
One other thing. The module sub base has slots, so if a user doesnt want to use prisms, the sub base can be slid so the aperture lines up with the laser beam..

I'm definitely interested in obtaining a blue module from you or anyone else for around the price mentioned. At this point I am just holding out to compare results.
Also, while you are designing... a big problem that I have is that adjusting laser height is a pain. I have found that often just adjusting the focus of the laser will change the beam height slightly enough to mess everything up. I am thinking of possibly redesigning my enclosure so that instead of the modules being screwed down to my base plate, they will be mounted upside down on adjustable threaded stilts. My reason for mounting them upside down is so I can mount a properly sized heatsink/fan to the mounting side of my module while still being able to keep the beam an inch or so above the base plate. Something like this is very desirable for me so that I can easily adjust beam height as quickly as adjusting a dichro mount without having the need for an intermediate bounce mirror. Just something to consider.
Thanks Dave !
I am definitely interested in at least one !
Cheers
Unfortunately no optics. I think Simon still has some prisms left he may part with tho. and the o-like collimator is probably the best choice atm. In the future i hope to get some m9 retainers made for some other lens options
A super feature on this one, is its possible to remove the lid whilst the module is screwed down to the base plate, should the need arise to tweak the module in any way
