Keep in mind to mine these at a decent hashrate (4MH), you only need 5 watts (1A per port). The original moonlanders you needed at LEAST 7-10 watts to mine anywhere near 1MH so these are way more USB port friendly, and alot more hubs *should* work with them.
1 amp is easy on a stable usb hub. that is very power efficient when is the next batch?

scroll just a few questions back - pre sale orders most probably from mid of october to november. after all the presales might come a second batch. so there is definitely no announcement for a second batch. You will have to wait ![Smiley](https://bitcointalk.org/Smileys/default/smiley.gif)

Just checked bitmain: L3 504Mhs for 2200 USD.
100 x USB miners = 500 Mhs 100 x $80 = $8000
L3+ @ 2200 USD, even if it is a cashed page, is 400% cheaper.

These are meant to be lower cost, power efficient devices to allow/entice/enable new miners an alternative to burning up their video cards. The more people mining, the better.

The final design has been locked in for production next month, and I'm happy to reveal it you all! PCB is a cool matte black design, with the same anodized black aluminum heatsink as the original moonlander. I decided to include both memory voltage adjustment in addition to core voltage, as my tests had an efficiency gain of 10-20% for ASICs that can handle lower memory voltage! As a super thank you to all who pre-ordered I decided to include a 25mm fan into the cooling solution as well, so no need to come up with clumsy external fan solutions to keep these cool. A top side small ASIC heatsink will also be included to further increase thermal efficiency (it will be black not blue). With this setup I've achieved 1.6W/MH all the way up to 800mhz, which is 4.6 MH of hash power for just 7.5 watts! Pretty impressive for a chip thats designed to do 3.8 MH at the same watts. Check out the pics below! ![](https://ip.bitcointalk.org/?u=https%3A%2F%2Ffarm5.staticflickr.com%2F4355%2F37391800115_7d5fc65b69_c.jpg&t=665&c=oRqs9w2J4JYy4g) ![](https://ip.bitcointalk.org/?u=https%3A%2F%2Ffarm5.staticflickr.com%2F4362%2F37220187022_161420de30_c.jpg&t=665&c=8b7zIFfTWHxrQQ) [/url]

Got a quibble with your original post.
USB 2 is limited to 500 ma at 5 volts, or 2.5 watts. You're not going to pull 3 Megahash on a stock USB2 port without going well beyond it's specs.
USB *3* has a 900 ma limit - 4.5 watts - THAT'S where you can pull enough power out of the connection without exceeding specs to get close to 3 Megahash.
USB "battery charging" ports are special case upgrades to the USB 3 specs for power distribution, and a lot of "powered hubs" are capable of quite a bit more current per port than the spec requires even if they don't meet the full "battery charging" specs.
Stick miners have NEVER been intended to compete on a hash/$ basis with a "full" miner, there are way too many overhead costs that are always quite a bit higher per chip.

thats why we were told to buy special powered usb hubs or build on your own. i already did that .. was not to hard to do ![Smiley](https://bitcointalk.org/Smileys/default/smiley.gif) (adding external power to cheap usb hub) i planed to take some more pictures but it was done so easy and fast .. i just forgot .. lol https://www.dropbox.com/s/hn0vmmh7xw11ufo/2017-09-23%2011.20.45.jpg?dl=0https://www.dropbox.com/s/4c32auzxj7kbizt/2017-09-22%2020.20.19.jpg?dl=0Cut off the red wire and weld wire from power supply (+) on the pin. weld (-) from power supply to one of the shield from an usb port (mass). Done! Greetings - Astrali

My original post was never comparing USB 2 ports....most people have USB 3 ports these days, and in its current config the stick can do almost 4 MH on USB 3 power. I was mostly stating the fact that you can stick this in your normal USB 3 port without extra hubs or anything else and it will run at nearly full speed. EDIT: nvm i see where the confusion came from...I had mistaken listed USB 2 in my OP and meant USB 3.

Hi guys, I bought 2 of these but I will receive them in few months. I'm a noob in mining, they are my first mining materials. I know they will come with some instructions but I would like to learn and be prepared when I will receive them. Can you please point me to some good resources to learn about mining. I know they are plenty of them, it is not laziness, just want to know where to start and what is appropriate to know for these (algos, solo vs pool...)?

You have to learn about - Mining pool - Mining tool (like bfgminer, which may be distributed by jstefanop)

So, I'm not comfortable hacking together my own USB powered HUB. Most likely I will buy one or more. If I have an old MacBook Pro early 2011. Everything in USB system report says Current Available (mA) is 500. Can I purchase external AC powered USB 3.0 hubs and attach it to the USB 2.0 port? Would I be able to use Moonlander 2 at full power this way? Or do all ports have to be USB 3.0 capable from start to finish? I hope the question makes sense... It'd be a shame and waste to run less than 5 MH/s on the Moonlander 2 I pre-ordered.

Hi y'all - This will be my first time mining, and I've started to gather all of the necessary supplies. After checking all of the Moonwalker threads it seems most of the powered USB 3.0 hubs that have been recommended are no longer available and I don't feel comfortable rigging together my own hub as mentioned above. After some digging I've found this, although it's pretty expensive. Will it fully power 10 units? and/or has anyone found a cheaper one? Thanks! https://www.newegg.com/Product/Product.aspx?Item=0XP-005K-00058&cm_re=powered_usb_3.0_hub-_-0XP-005K-00058-_-Product

You will never make your money back running one of these. As it sits the ROI is nearly 2 years at current prices, meaning you will be priced out by the difficulty adjustments and never break even. Then you add in the costs of a powered hub and you are just throwing money away. I just dont get it....

Stop buying industrial miners, running them at home, and then complaining about the noise.

You won't FIT 10 Moonlanders on that, the ports are too tightly spaced.
