Finished a mod (finally) on a fairly big zoomie - the Xanes X915 P10, bought here on Ali. Came to my attention in the Zoomie thread here, Texas Toasted posting here. It's listed here on BG, but a bit pricey.
Originally planned on a SBT90.2 but decided against it because I got a SBT90.2 in a 1504 already, and the heat is not handled very well. So, a white flat W1 will do with a FET+1 driver running my tweaked Anduril. Plan is to use lighter gauge long leads for the LED's, since they already have to be long through the tube.
From the listing:
Stock parts. Notice the long wires that are needed, and the white plastic centering ring will be tossed.
USB Charger/power bank support:
Driver electronics (partial):
Switch, LED's, and more driver parts:
Driver parts stripped:
Lots of wiring needed to make use of the LED's on each side of the switch, plus switch wire, and batt+ to the board:
FET+1/Anduril installed. Spring replaced a small brass button. I wanted heavier, more wiring on Batt- grnd to help with drawing heat away from the driver, since it's not properly mounted. The Batt+ to LED is already taken care of. The green LED's go to MCU pin #2, while the blue LED's go th MCU pin #7. Anduril supports it on both pins, but currently they do the same thing. I was able to use 2 greens and 2 blues, half of what the light has. The stock driver/MCU controls 8 LED's individually from 6 I/O pins. It provides both + and - to the LED's. If the MCU switches the polarity, the other LED in each pair lights up, so they must be alternating polarity to light up both, probably via PWM's. For this driver with the ATtiny85, I simply wired one side to ground so I could control 1/2 of them.
Copper round, 14 gauge, on backside of the shelf, thermal epoxied in, reflow of the W1 on a stock 3535 XP MCPCB:
Drill/tapped 2 screws, used MX4 under the MCPCB:
Close-up of reflow job, I think it's ok, not perfectly centered:
Backside after mounted:
26 AWG long LED wires got 5 amps on a Samsung 35E, but want to do better. Tried 24 AWG and it bumped a little to ~5.2 amps, so I added a 22 AWG spring bypass on the tail.
Here's how it looks:
Compared to a couple of other similar throwers, 1504 on the left, Noctigon K1 on the right:
Now with a B158 on the right:
Results:
Recorded 717 kcd taken at 5 meters (just over 1 mile), on a 4.19V Samsung 35E. I think that's in the ballpark of what I'd expect. The hot spot is tiny - somewhat difficult to get the reading but after some re-positioning of the meter, I could clearly hold it in the 700 -717 kcd range.
Sorry, didn't get a firm recorded measure on the lens width but when I did measure it, I found it to be about dead-on with the 1504's lens, though the Xanes is plastic, not glass like the 1504.
The green and blue LED's look awesome, specially with Anduril 2 level brightness controls.
