XRE’s have contacts top and bottom. In fact, much of the top side is covered by copper with a narrow gap separating the +/. The + bond wires span this gap to the die. I’ll be soldering the wires to that copper. Removing the bottom side +/ pads will allow the pill to become the mcpcb.
Terry, I think sanding the 15 mm Mtn board down would be the way to go. As long as the ground rings are continuous with the vias at the edge then it will work. Part of the reason for the copper pipe though is to give me a place to solder the ground connection.
Thanks for the lesson. I was a little lost there for awhile. :+1:
I fully intend to try again after the holidays. The copper I am going to run with that. We over thought it. You took it and made it simple. Excellent thinking.
And the tail switches, even on one that I do not mod need to be changed.
I'm working tonight so I have not had a chance to take a current reading. I have a 98 with an 8*7135 in it and got 2 18650's with that order today. Suppose to be latest and greatest. I will post both as soon as time permits.
Another bumpdate. My order from Rich arrived so later this week I’ll part swap to a 15mm driver board that was part of the order.
With the LG battery and stock board
All I did to it was change it to constant current. I got 1.75. My sk98 I've been playing around with has the 8*7135 it almost got 4amp. 3.92 then it stopped lol. So gotta get that board to work in the 68. It still blisters anything around here it's size.
Wow! Very nice light! I missed this thread somehow until today!
Nice to see it finished :+1:
Never cease to amaze Scott! Your attention to detail and imaginative creativity is off the charts, thanks for sharing in pictures so we can see the lineage (in and of itself the picture taking along the way is quite the chore, most don’t realize how horrible the intrusion is when you have to stop for pictures while working up this stuff)
That little AAA MiniMag you did for me is still a treasure to me. Still don’t understand how you could manipulate the driver like you did, among other things. What a mindset…
I’m reading the burl was sanded to 10x smooth with 2500. That brings out the figure and makes it feel great. You can wax it or tung oil to keep moisture out. 100% pure Chinawood tung oil
This exemplifies what BLF is all about.
Take a sad light and make it better.
