I may be remembering incorrectly, but I thought the Tk75 battery carriers were designed to so that they were electrically parallel. So 4 carriers would be 2S8P or 8.4v at full charge. EDIT: IIRC, the stock TK75 driver is a boost driver and the LED's are wired 3S. You might be able to recoup...

I have edited the above post as the seller issued a prepaid return shipping label and fully refunded my order. The seller was very cordial and helpful in resolving the error they made. Really was first class customer service. I believe the error was an honest mistake. I definitely will give...

^ I was premature to call the vendor a scammer. I didn't realize it until a few hours ago, but they have tried to contact me multiple times about the dispute I opened. They have apologized for the mistake and have offered a couple ways to resolve including providing me with a prepaid return...

^ Odd thing is the package was well packed. Nice sealed anti-static bag, Tons of tight bubble wrap. Ordered on 1/8, arrived yesterday. If it wasn't for shipping being changing to $300, I would be inclined to think the above may have been just a mistake. EDIT: While discussions with the...

^ Yeah, pretty sure he/she/they is a scammer. Ordered a laser bank of NUBM08's to just play around with in odd hosts. Was supposed to be new, but got this. Beat up all the way around. Maybe they used a chainsaw to get out of projector or something. Lenses look like they may have been...

Thank you RC and LT17. I'm very happy with the focus on mine, which is why I was surprised how long the beam pattern is. Very narrow. I don't think I could tighten the focus any further with the existing g-ball. I'm close to finishing the host. I'll post a picture of the stock beam pattern...

I received a couple of these LD's. When testing to just make sure they work (20mA in 12mm modules), I was surprised by how long the beam pattern is with just the stock g-ball. The width is very tight. Are all 450'ish g-ball LD's like this? Wondering if holder for normal G2's, 3E's, etc...

Nice build and great info. Googled to see if I could find info on these diodes. Not much out there. Found the below, but the vendor doesn't seem to have much of a track record (at least not on AE). Does anyone know if any of the counterfeit N!ch!a$ have been sold as assembled arrays...

I saw something on the news about that incident. I don't know if they were showing actual cockpit footage from that incident or just some footage they keep in stock. The beam stayed dead pan on one of the windows. No one could hold a laser that steady on a moving aircraft. Seemed to me like...

^ I think both are equally impractical. That is why I said "If". Some agency (I can't remember) announced 1 million drones will be opened on Christmas day. Seems like an over estimate, but with current prices, the number will be substantial. Here is a FPV quad for $90 (day and a half...

If all RC aircraft (aka "drones") are required to be registered and it's a success, lasers will be next in line. This is very different than vehicles. I can own as many cars as I want. I only have to register the ones I am currently operating on public roadways. Sad thing is, the folks that...

Thing of beauty there. That you for sharing.

Very sweet build. Thank you for sharing.

^ Same here. I received all the parts yesterday (well, the package arrived. Haven't opened it up yet). It may be a bit before I put everything together though. Have a lot of time demands right now and still need to pick a host and mod it to hold the emitter.

Thanks for the advice gentlemen. I was thinking about soldering copper sheet each pad. The sheet would then mechanically bonded to the external inductor. Actually, the order would be reversed. Like Benm recommends, I would had solder the copper sheet to the PCB as it would take way too much...
