Just wanted to let you guys know what you can look for from mine- I’ll be designing new boards for mine to be a 3s buck driver using components from an HX-1175b. The driver/upper contact plate will be one board and then either mod the factory tail plate or make a new one for 3S. This will drive either a 3v or 6v emitter upwards of 8A via sense resistors and uses a surprisingly small number of components.
Change of plans, instead of stripping HX-1175b’s I’ll be designing a whole new driver based on the MAX16820 buck driver (an individual component). Spec’s are pretty awesome, 2Mhz switching, very high PWM in, should be pretty efficient especially when able to use a nice large board with large Cu pour for heat dissipation.
i cannot decide whether to buy this courui big head or the UF-1405(please don’t say buy both). which one gives more throw after modded (lets say dedomed, and driven @ same current)? anyone here has both and can give some numbers for comparison?
This is the DO1 with black anodizing. The original was grey I believe.
Amazon is the only place I could find it in stock today.
DX had them 2 days ago, but today the listing is gone.
I do not know if it is different inside.
Some sites show 1000ma driver, one shows 1800, most show no info.
I ordered one anyway. For the price it’s likely to be a good buy.
Have a buddy wanting one of these, should I order for him using my account (either way it’ll be delivered to me) or is it cool to share the code with non BLF members?
I have some nasty words for you sir. I can not afford such an option! I’ve kept myself away from this one since the original thread because of the emitter shelf…
Got me there bro. Ha ha. Wasn’t paying too much attention to the the latter part of the OP.
Any chance GB can ship units in Gray? I already have too many black lights.
