Yes, good questions.
Downboy exists as of today but not in its final configuration. A little hiccup in that I ordered the old board and not the new board so the raw boards that just came in friday are bunk. Sure, they are fine but the older boards have components on both sides. The new boards are cool in that they have components on only one side and have the battery round copper spot on the backside. This will allow the DownBoy to go into the Ecan modules like the Badboy.
DownBoy does not work with the connectors and emitter board for making a Sammich.
DownBoy will be offered in 300, 400, 500, 700, 750, 1A and 1.5A models.
Downboy is very friendly and is in DD when Vin is less than Vf. The IC still sucks power so it's not a true DD and high efficiency. Especially at very low Vf voltages its possible the IC is drawing more than the LED. When Vin=Vf is when the IC starts trying to work. The IC starts regulating when Vin > Vf and will maintain regulation up to 16V. It can be ramped from below Vf to above Vf and the IC kicks in pretty smoothly during the transition zone. It will also fall out of regulation nicely and transition to DD pretty smoothly.
Downboy has no moonmode setting. It will drop into DD mode and will operate that way till the batteries die. The one runtime test I did it continued to run another 6+ hours but at some point the LED was just a faint glow.
The plan now is to order another small batch of boards which would take 2 weeks. Assembly would add another week.
As soon as I get the new boards back from assembly I will quickly test one and immediately order a large run the next day.
Volume production quantiy would then be 2-3 weeks from that time.
I have some at present, but, they are the double sided component version and they are all Downboy 400s. Adding sense resistors will make them the other versions.
At best we are about 6 weeks out for any volume.
