  1. Single board computers come in all shapes and sizes, from the Raspberry pi, to the odroid h2. While there are several differences between all of them, they usually have all of the nessacary components, or at least the essential components to operate all in a single PCB, thus the term "single board computer". A new addition to the rather large (and loosely defined) family is the UDOO BOLT, which is a single board computer that will have an embedded Ryzen CPU. https://www.google.com/amp/s/liliputing.com/2019/03/udoo-bolt-single-board-pc-with-ryzen-embedded-starts-shipping-this-week-crowdfunding.html/amp So don't expect the same level of performance as the desktop CPUs, but this may be one of the most powerful single board computers on the market. First off, let's talk about the form factor. While I could talk about how small that is, I think that showing would be better. 4.7 inches equates to roughly 120mm. So if you have a 120mm fan lying around, you can roughly judge the size, which needless to say, is quite tiny. Now let's talk about the CPU options. Both of those are low power, both of them having a 15w TDP. The V1605B is the same exact CPU that the upcoming Smach Z is using, which seems to play most modern titles at around 720p at 30-60FPS, which for such a low powered CPU, is rather impressive. While this won't be a proper desktop replacement for gamers, it could serve that purpose for general use, the Arduino compatible pins are what's going to interest tinkerers though. 32 GB of EMMC is too small for a Windows installation, but it should work with most linux distros. There are SATA ports for HDDs/SSDs though, as well as an m.2 PCIe slot, while you would traditionally think to put an SSD there, you are able to hook up an external GPU to the lattepanda alpha (another powerful single board computer) with an adapter, and I wonder if the same thing could be done here. Strapping on an external GPU and PSU (since the GPU needs to be powered) kinda defeats the purpose of the small form factor though. And now the elephant in the room. This is a kickstarted product, that's not nessacarlly bad, but kickstarted projects tend to have a rather bad reputation of not delivering, this product was already supposed to be shipped out last year, and it's almost April. However in the grand scheme of things, 1/4th of a year isn't the end of the world, and it seems like the early bird backers will get the first batch. So not available to the general public yet, but that will hopefully change in the coming months. And now for an opinion piece from me. I have recently gotten into single board computers, and this interests me for several reasons. First off, I don't think that I have ever seen a Ryzen single board computer, and second, this is a lot of power in a small form factor. The most powerful single board computer currently is the lattepanda alpha, which I already mentioned briefly, but that board has some limitations, soldered in RAM, no SATA ports, etc. It's a great board, but it's limited in expansion, while that makes it very thin (as well as smaller then the UDOO BOLT footprint wise) it limits what you can do with it. Furthermore, the GPIO on the lattepanda alpha can only be controlled by the on board ATMega32u4 microcontroller, which connects to the CPU via serial interface, further limiting what you can do with the board. So my hope with the UDOO BOLT is if it gives similar, if not greater CPU performance without the shortcomings of the lattepanda alpha.
  2. https://www.digitaltrends.com/cool-tech/pale-blue-rechargeable-smart-batteries/?amp While the article talks about them lasting more than lithium ion batteries, the kickstarter makes no mention of that on their kickstarter. 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. 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.
  3. If you want to try to mock me, at least get the battery chemistry right. Here, I'll help you out. https://www.amazon.com/Rechargeable-Batteries-Quick-Charge-Micro-USB-Charging/dp/B07J9PQ1CN/ref=sxbs_sxwds-stvp?keywords=lithium+aa+batteries&pd_rd_i=B07J9PQ1CN&pd_rd_r=162a9f3e-d251-41d4-9c5d-1515e7c86c5f&pd_rd_w=lF56Z&pd_rd_wg=Jw3Qu&pf_rd_p=d006b618-5fac-44e6-850d-a0fdd19f7847&pf_rd_r=PTA9JZVQMM2Y01JXVMBK&qid=1565477475&s=gateway&sprefix=lithium+ Li-ion instead of lipo, but at least it's lithium.
  4. You can still find them. https://www.amazon.com/gp/aw/d/B01MFI0KIB/ref=ox_sc_act_image_1?smid=A9QIOY9HGDU88&psc=1
  5. 18650 batteries can, so I don't see why not. Would be pretty goofy looking though.
  6. The addition of asphalt makes them charge a lot faster. There is apparently sodium batteries that are looking quite promising in terms of the energy density department.
  7. I think the man actually has an 18650 battery loose in his pocket with some spare change that shorted it. 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.
  8. I might check him out, I'm wanting to make 18650 battery banks for solar and wind. Electricity is expensive during the winter here.
  9. Model number is LGDBMG1185 and N329K254A7. They are LG OEM batteries that was extracted from a dead MSI gaming laptop. 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.
  10. At least one.... No, I'm not using a current limiting resistor. #livingontheedge
  11. 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. NiMH batteries don't need overcharge, and over discharge protection circuits, the USB ports also cost money, as well as the LEDs. Lithium is generally at 3.7v, so I would imagine that there is some switching circuitry involved in these batteries. I agree, although I can see it being useful for travel folks and whatnot.
  12. https://m.hexus.net/tech/reviews/storage/133292-team-group-cardea-liquid-m2-pcie-ssd-512gb/ 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. Which they are not doing. Honestly, I find companies who pull this crap rather insulting. 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.

    PSA: reapply thermal paste to your GPU!

    Do you realize, how much troubleshooting we did before that? A LOT!

  15. And this is why the LTT fourms don't allow political discussion. Holy shit what a fucking trainwreck! Someone, bring me some eye bleach! Seriously though, fuck this shit, I'm out of this thread.

    What did you do with your Ryzen or Intel stock cooler?

    I commonly put them in the freezer and use them as a cold compress for injuries.

    Thread for Linus Tech Tips Video Suggestions

    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?

    AMD compatible RAM 3200+ ?

    Early Ryzen CPUs were pretty picky with RAM, only likeing single sided Samsung B dies. https://www.newegg.com/g-skill-16gb-288-pin-ddr4-sdram/p/N82E16820232530?item=N82E16820232530 This is what I use, and I easily get 3200mhz quad channel on Threadripper. Someone said that they were able to successfully overclock it, but your mileage may vary.

    Some temperature controlled switches, I want to automate the greenhouse fans with it. It's wired up and works well.

    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.
