Nitpicking, but ballsy to do it powered, to demonstrate.
I think you were shorting out the MCU output to the LEDs a couple of times when removing them (when both went out) ?. Encouraging that it survived a couple of brief shorts to ground. Maybe a “don’t try this at home” warning ?
Don’t tell Tom, but I flashed ToyKeeper’s new ‘Andúril’ UI to one of my Q8s. It’s awesome! :heart_eyes: ‘Lightning Mode’ is soooooo fun!
I mentioned my pink 0603s in an earlier post. Here they are compared to the stock green emitters.
They’re rated for 3.0 - 3.2V and are running dimmer than the green ones with the stock resistor, just as I had hoped.
I got the ‘T’ straight but must’ve bumped the PCB.
BTW, ToyKeeper is currently working on adding indicator LED support to Andúril, so my green switch is dark for now. This photo is from before the reflash.
It's ok, no prob. I'll just slowly fade away..... Replaced by a newer, younger, no doubt prettier, and probably smarter programmer.
Ohh - on the 3rd modded Q8, got this: 7,110 @start, 6,510 @30 secs Dang!! All 3 within 200 lumens of each other, and again, not touching the LED's, LED wires, or FET.
Should be possible to hit 1,800 lumens per LED (7,200). Thinking the LED wires to 16 AWG and FET to SIR404DP, maybe improvements under the MCPCB (better grease, sand surfaces to 2000-2500 GRIT.
Placed an order for the minimum qty (3) and the price was $0.95 with standard USPS shipping. Currently going through the posts to find the switch and resistor related comments.
Well, I'm not set up to measure amps for those tail MCPCB mods. I could swap tubes with the prototype that does have the clamp meter loop, see how close it performs in lumens, and if close, then can use it to measure amps. Thinking it's in the 20A-22A range though for these kind of numbers, based on my proto measurements.
Lexel, what is the thickness of these boards? Oshpark does not tell me.
The stock board is 1mm thick, but if they are the same thickness as the drivers that I’m used to (1.5mm?) they stick out of their gap in the Q8-head a little, which could cause the silicon cap not fully touch the rim and this could theoretically make it less waterproof, plus that the retaining ring does not screw in fully.
