2017-10-27 update
Problem fixed. We have manually fixed the drivers, made 3 samples. Video here.
No pre-flash. OK.
Starts at moon after 3 seconds off. OK.
Will make a new batch of drivers and then assemble.
I could send you new drivers . But the driver is press-fit into the alu pill, it might be hard to pull out. I might send the whole assembly. Easier to swap.
Driver = 4$, assembly = 6$
--------------------------------------
Well, actually some problems happened with the 1st small production.
1. It has a pre-flash for the moon mode. (Not very obvious unless you look closely)
2. It is supposed to start at moon every time. But it seems to have a memory of 30-40 seconds, well it is not actually memory. Memory means it remembers the last used mode, but it goes to next mode.
Pre-flash is something I definitely won't like. Regarding the "memory", some might take it a bug, some take it a feature.
Reason is that it has a capacitor, which stocks some power after the light is off. After some discharging, there is no flash or "memory" anymore.
The capacitor was meant to prevent any demange from the surge since it is a boost circuit. That engineer was not considering the pre-flash a problem (defective)
And I was too wrong to discover it timely since the production was already done. Luckily we didn't make many of them. We could still do improvement. It might take one month for the perfect version.
It was priced 45$ and group sold on Massdrop at 33$, now I'm selling the "special version" at 20$, if orders reach 150pcs, it's 18$. If only you could accpet the pre-flash. Here is a video of demo.
(If you already ordered from MD, pls contact me for refund of 13-15$)
Pls reply "in" in the thread if you are interested.
Pls reply "amazon", if you are in US. They could ship a little faster.
