    Hm so there's safety considerations that need to be built into the battery to avoid the risk of bypassing them accidentally, 


    I think the man actually has an 18650 battery loose in his pocket with some spare change that shorted it.

    as well as a need for a built in voltage regulator to actually match the "AA spec". 

    The only lithium technology (that I know of) that comes close to the AA voltage spec is lithium titanate. 

    A resistor could also be used, but that's incredibly inefficient. 


    Any form of switching power supply would need a capacitor though. 

    A liner voltage regulator would also work, but still wouldn't be as efficient as switching.

    For those who don't know, Mooch is a self described "electron wrangler" who does extensive testing of batteries for the vaping community. Disclaimers aside, his battery charts are basically the bible for those wanting to do custom coil configurations in their vaporizers.

    I might check him out, I'm wanting to make 18650 battery banks for solar and wind.


    Electricity is expensive during the winter here.

    What brand and model?

    Model number is LGDBMG1185 and N329K254A7.


    They are LG OEM batteries that was extracted from a dead MSI gaming laptop.

    Love my brown LG 18650's

    LG and Samsung are both great, however. 



    These are flat top 18650 batteries.  They aren't going to be compatible unless you're willing to cram some aluminum foil on the positive end.

    Another kickfarted product, you can get LiPo AA USB rechargable batteries on Amazon for less than they're pledging for.

    I found some li-ion batteries, but no lipo batteries. 

    Also, the only 2000 mah that I found was NiMH.


    Although it does seem like there are lithium ion batteries on Amazon that offer similar functionality for slightly cheaper.

    $30 for 4 batteries, jesus christ. $30 can buy you *150* nonrechargable batteries, or 20 traditional rechargable batteries with 2000mah capacity... 30% better than this kickfarter

    NiMH batteries don't need overcharge, and over discharge protection circuits, the USB ports also cost money, as well as the LEDs.

    Is it an issue where you can't get something near 1.5 v with the cell configurations that are possible?

    Lithium is generally at 3.7v, so I would imagine that there is some switching circuitry involved in these batteries.

    Also Having a charging port built in seems like a waste of space, you can just use an external dock for it like all other rechargeable batteries.

    I agree, although I can see it being useful for travel folks and whatnot.

    While the article talks about them lasting more than lithium ion batteries, the kickstarter makes no mention of that on their kickstarter. 


    Pale Blue lithium polymer (LiPo) smart batteries, currently in a Kickstarter crowdfunding campaign, can be recharged more than 1,000 times with a unique USB charging method. Presently with close to $100,000 in pledges, more than ten times the campaign’s all-or-nothing goal, the Pale Blue AA and AAA rechargeable batteries have advantages over both single-use alkaline batteries and nickel-metal hydride (NiMH) rechargeables.

    The success doesn't surprise me, rechargeable lithium AA and AAA batteries are something that people have wanted for a while.  While there are non rechargeable lithium Energizer batteries, non rechargeable batteries are both wasteful both money wise and environmentally wise.


    You don’t need to carry an old school multiple-cell battery charging case with an AC adapter cable to recharge Pale Blue’s smart USB LiPo batteries, either. Each battery has a micro USB port and an LED charge indicator light. You can plug a regular USB cable into the micro USB port with the other end of the cable plugged into a USB-AC adapter or a USB port on a computer, a lamp, wall outlet, or multiport charger.


    That's actually pretty neat, but I can see recharging multiple batteries at once being a bit of a mess.

    This also brings up the question on whether or not these batteries are compatible with devices that can charge regular nickel metal hydride by just plugging them in.


    Let's also keep in mind that this is a kickstarter project, and a lot has gone wrong with kickstarter projects in the past.  But I will remain cautiously optimistic.

    It won't have escaped your attention that the drive isn't designed to be part of a larger loop, meaning the liquid isn't transferred to, say, a radiator in order to dissipate heat. Instead, the small pool is intended to draw heat away from the aluminium pad, and then, in Team Group's own words, "the heat of the water cooling M.2 SSD module can be transferred with convection produced by the computer case fan." Begs the question, if there isn't much airflow, will the liquid become detrimental as it begins to warm?

    I think that Linus has already tackled this concept here.


    Seriously though, there are a few more flaws outside of the fact that the liquid can't cool anything without it circulating.  NAND actually likes being warm, it degrades slower when warm.  The only part that would benefit from cooling is the controller.



    There are a couple of other caveats, too. On closer inspection, our 512GB review sample reveals that the thermal pad lining the aluminium heatsink makes reasonable contact with the NAND memory chips but doesn't actually touch the controller or cache; there's a clearly visible gap, which doesn't bode well for heat transfer. 

    Which they are not doing.  Honestly, I find companies who pull this crap rather insulting. 


    Team Group reckons its patented cooling module can lower operating temperatures by up to 10 degrees

    And cats can fly. 


    Also, don't think that you aren't paying a premium for this drive.



    You can find 1TB m.2 drives for about 100 dollars on Amazon. 

    Also, Samsung's m.2 drives have a 5 year warranty for the same pricing. 


    I don't really have much else to say.  You're paying a premium for a feature that's most likely falsely advertised, it looks kinda neat, and that bubble would make this m.2 drive double as a good level, but save your money and just get something else. 

  7. Alright, so I just discovered a non x Threadripper sku known as YD1920A9UC9AE.

    There are a couple of chips on ebay going for 200 USD, I did a bit of research and apparently motherboard manufacturers do reference this particular part number, it's a 12 core CPU that has a base clock of 3.2ghz, and a boist clock of 3.8ghz.


    I don't think that ebay links are allowed, so have a picture. 



    I have no clue where these CPUs are coming from, but my guess would be OEM systems.  Perhaps getting one to mess around with would make a good video?

    Does this work well? i'm looking for a soldering iron that's not too expensive. I don't like the gas ones thought

    It works pretty well, no temperature adjustment unfortunately.  Use nickel metal hydride batteries though, and keep a spare charged at all times. 

    I'm using lead free solder which requires a lot more heat then leaded, I get about an hour, so I can see two hours for leaded solder. 


    Unfortunately the tips are proprietary and expensive, and you only get the round tip with the soldering iron, which is my least favorite for wire.




    That's the tip that I generally perfer. 

    Expect to pay another 20-30 dollars for a tip set.

  9. I just got this today. 



    A battery powered soldering iron. 

    It uses 4 AA batteries, and claims to last to up to 2 hours. 



    I'm wiring up some 12v computer fans for cooling my mom's greenhouse for the summer (powered by a 12v deep cycle vehicle battery), I can't really bring my soldering station outside so that's why I got the battery powered soldering iron. 


    That's a latching power button (that I also got today) so all that she needs to do is push it to turn the fans on/off.


    I'm going to 3D print a holder and mount for the button today. 


    Here is some temperature charts for alkaline and NI-MH batteries.
