Sourcing parts #1

Hey, this is an amazing resource. Thank you for making this open source! I was wondering if you can get the DMD module as a spare part without buying the whole device. Cc: @ranranking

The DMD and required control ICs can all be sourced from TI in single quantities, and can be purchased directly as a consumer. The only challenge to a full custom implementation are the interposers (item that connects the DMD to an FPC). This is a part that is hard to make without specialist manufacturing. TI lists some manufacturers that make these interposers. Neoconix will sell them, but with a minimum order quantity of 100 (at ~5$ a piece). This makes it tricky for a true sourcable open hardware project unless some kind of group buy is set up.

It might be possible to solder the DMD directly to a PCB, but I don't know if that would work and it is certainly not recommended as far as I can tell.

Other than that, everything can be designed and bought as a consumer. Estimated cost for full implementation is around 300-350 dollar.

I will be working on getting an open source design around the DLP301s in parallel to the other openMLA projects. (which would encompass PCB + basic software + hardware for mounting the DMD etc). If you know anyone interested in helping out we could combine efforts but its a fun project either way :)
