    Internal usb charging; best/safest method?

    Ok pretty much have it figured out. This third chip i have works fine. After looking threw some data sheets it seems like there are two different kinds of short circuit protection. One is called PASS the other is external short protected. It seems PASS is internal and external short protection...

    Internal usb charging; best/safest method?

    I see what your saying now, this third chip wont activate until a load is applied as where the other ones just needed voltage and they turned on. I think it will turn out that not all protection PCB's will work with the Pano's and or IMR's . Got a feeling this PCB will work when the battery...

    Internal usb charging; best/safest method?

    Loaded or unloaded they wont work with the CGR18650CH pano's. The Protection PCB's turn them self's on as long as the voltage is in range you get a output voltage reading, not sure what you mean by activating them. They work fine with a Li Ion lots of vapor. Slap a CGR18650CH in the battery...

    Internal usb charging; best/safest method?

    I just tested with some older lower amp PCB's i have laying around same thing. No Joy. My best guess would be that AW IMR's will not work also. That is if my theory is correct and it has to do with the low impedance of these high drain batteries. I dont have any AW IMR'S so i cant test them. The...

    Internal usb charging; best/safest method?

    I got my order of protection chips the other day. Slapped one in the test circuit for the mod i am building and they wont work with the high drain Panasonic's. The CGR18650CH's have 3 times lower impedance then the regular Li ions. my best guess as to why they wont work. slapped a regular li Ion...

    Mod Help pleeeeeaaaase...

    yeah it can be done. you just need a 4 posision switch that is on-on-on-on , the common on the switch would go to the regulator where you set the voltage with the PoT. The the 4 poles would each have their own resistor value for the voltage you want. After the resistors they will all go to...

    Looking for stock tube material for lathe work. 1" OD - 3/16" ID - SS, Delrin, anything?

    HSS can cut stainless it wont stay sharp as long a carbide will. Also depends what grade stainless your cutting and also what grade HSS your using. here is the wiki on HSS High speed steel - Wikipedia, the free encyclopedia this guide here explains the different grades of Stainless Guide to...

    Looking for stock tube material for lathe work. 1" OD - 3/16" ID - SS, Delrin, anything?

    The Carbide Inserts come in triangles. You can just turn it 120 degrees when dull and get a fresh cutter. They can also be resharpened or you can just bolt a new insert on. Those wheels are made for faceting or lapidary machines i dont think they can handle the RMP's of a grinder. The cutting...

    Which iast longer?

    Top of the line switching buck regulators that are around 96% efficient. The best boosters are around 86%. It is actually more efficient to buck down, Plus it is less stress on the batteries. boosting to 5 volts 2.4 amps from 3.2 volts requires 3.75 amp on the input side of the booster. really...

    Looking for stock tube material for lathe work. 1" OD - 3/16" ID - SS, Delrin, anything?

    I would get at least a 6 inch Dial caliper you can do quite a bit with that.inside outside length and depth. You can get them in digital but personally i think dials are much betterhttp://www.harborfreight.com/6-inch-dial-caliper-66541.html It your getting a 4 jaw chuck your going to need a...

    Looking for stock tube material for lathe work. 1" OD - 3/16" ID - SS, Delrin, anything?

    Nope , it would go in one of the quick change tool holders. Nothing else needed really for it. There might be cheaper ones out there but i would for sure stick with a insert system. You can grind your own out of HHS blanks but that is not easy to do. With that bar you just replace the insert on...

    This will do inside and outside threading.LittleMachineShop.com - Threading Tool, 1/2" Indexable HSS Inserts You can also use a tap to cut threads. cutting threads is one of the tougher things to learn on a lathe. Tool kit looks nice. The steel quick change is going to hold up a lot better...

    Is this the holy grail and answer to all my problems?

    You dont want the protection to be the same or higher then the Max rated amps. Higher it is not protecting anything. If what you made requires 10 amps when in use you really need to look for a more powerful battery because you would be pushing it to it's limit all the time. If you going to run...

    Anyone ever thought of using these?

    There is also the time tested Evercool Chip. Digi-Key - 296-22773-5-ND (Manufacturer - PTR08100WVD) you can slap any of these chips in that circuit and they will work http://www.e-cigarette-forum.com/forum/battery-mods/114901-evercool-variable-voltage-mod.html

    Is this the holy grail and answer to all my problems?

    That should work fine with 18650's that are of a quality brand.

    Do I have everything I need?

    Their is no such thing as 4000 mAh 18650 batteries. False advertising there. 3100mAh is the highest True rating there is for 18650's. You will be lucky to get 2200mAh out of those BRC batteries, They are really low quality. What happens is the rejected batteries made for reputable companies get...

    They are not made to turn stone. But i suppose you could if you installed a coolant system. You would need a steady flow of coolant on the diamond cutting bits. Also lots of patients cutting stone is slow work.

    Just to point it out again all these lathes grizzly , HF , LMS , Micromark are all made by SIEG in China. A lot of the bad reviews are user error and/or user ignorance. Knowing how to properly operate the machine and adjust it just is not known by most people who buy these lathes
