JohnnyMac’s review is my main source of relevant info at the moment; the BST itself is in the mail. I assume it’s mounted the same way though, which should make it really easy to access all the innards.
If I can’t flash the original driver, the next best option seems to be DrJones’ 46mm “Quasar” driver.
I should be able to get detailed pictures of the inside in a few days, if shipping is quick.
(also, assuming I can find a driver solution, I’m leaning more and more toward making it floody with custom firmware)
