ArcticMyst Security by Avery
First build: Survival Lasers 650nm
- Thread starter hazerkitten
- Start date
Hazer, I built a M-140 from DTR and a 1.5 amp host kit from Survival. As tested on my Laserbee it is 1.48 Mw. My only wish is that the beam divergence was tighter. It is not bad but I wish it was smaller.
My 500Mw 638nm from DTR, and a 1.5 amp host C-6 from survival is good for 750Mw output and is a nice color Red. The beam on the Red one is very much like a bar rather than a dot. Both have the three element lens.
This is just for your info. Have fun.

SB,
Wow, that is very helpful as that is pretty much the exact route I'm going. SL stuff is legit. I can't wait for them to get back so I can place an order!!

With the linear, I would use two 16340s. That what i got on my 650nm, two 3.7v batts with a moh linaer set at 378mA.
With one fully charged batt, it might not be different. However, when the batt drops below four volts, power will start to drop. It's likely that it would shut off before the battery is fully drained. With two batts, you could run them into the ground and not have a power drop.
The linear drivers are designed for two batts due to the voltage drop.

If you ever decide to roll on one 18650 seek out the Panasonic 3400mAh cells on FastTech. Those are hands down the best 18650 cells available. Panasonic does have a 2900mAh hybrid cell that's capable of higher sustained currents but IMO, those are only useful in single cell(boost driver) 2-3W+ 445nm builds since the 3400mAh cells can handle 5A sustained anyway.

Not that they are useless but the Panasonic ones are massively superior.
Hazer, The Panasonic's are great, but as far as I know no Panasonic's have a protection circuit built in. Just don't drain it too far before recharging it or it may damage it and it is possible that you may not be able to recharge it. There are a few companies that use the Panasonic and add a protection circuit but they are pricey. On set I bought cost me about $27 for two of them.
Are you happy with your 445nm and the 635nm? I was curious if you have checked the power of them. Just wondering if they were about the same power that mine are.

where do you get them in three? i know they have cheaper since i have the 2900mAh version
i know of where to get new panasonic, sanyo or sony 4 packs of 2200mAh for ~$4/battery shipped but they aren't protected.

I have never seen the 3400mAh Panasonics sold individually. I could however buy four and sell you three of them for cost. I am actually still working on stocking them to sell its just they are painful on the wallet to stock.

@Sb855 yea I found 3 good 18650 cells plus I just received 2 16340's pretty cheap from another site..wait for it 2.37 shipped,there ultra fire's.It's called banggood.com.Takes about 3 weeks to get stuff but a lot of there items are stupid cheap.I used to get most of my RC stuff there but I see a lot of items that could be used for this hobby..I love to repurpose
