do you need a partner with $ to ramp up production?

I ended up the USB 2.0 7-port hub from Plugable. Same as the USB 3.0 but $10 cheaper. You don't need USB 3.0 as the external power is same on the USB 2.0 versions.


You can try, but sounds like three Moonlander2 will work best. I was planning in using 4 Moonlander2 with this, but worried about Port 5,6,7 as two Moonlander2 will share one regular. Not sure if there will be enough watts for port 5, 6, 7.

As I discovered with my 7-port, 60W charging hub from Plugable -- pop it open and look at how the power is distributed.

On the Plugable, it takes 12vdc in and has 3 buck regulators taking that down to 5v  for the USB plugs. That said... 1 regulator feeds ports 1 & 2, the 2nd regulator feeds ports 3 & 4, the 3rd feeds ports 5-7. See where this is going?

After futzing around with 2x of the 2PAC's along with an original Compac just plugging them in 1-2-3 I was unable to run all 3 at decent speed without at least 1 stick dropping out. Looked inside the hub and found ^^ so...

Put one 2PAC on port-2, the other on port-4 and the Compac on port-6 so each stick has it's own 5v regulator.

 without special adapters the sipolar 10 hub can fit 6 of these and the eyeboot 8. at 245 for the eyeboot i think its not a good buy.

 Sipolar is USB2 (not an issue of itself) and only .6 amps per port rated (DEFINITELY an issue) - not a good option.

 The ports on the Block Erupter are too close together to be able to use all of them, it would probably handle 28 Moonlanders though (one every OTHER port on each row) but even then cooling might get a bit iffy without a substantial fan blowing lots of air into it.

Any insights/experience as to whether something like this

could work for powering a _single_ miner?

 Per the specs, it should work well even for an high clocked Moonlander.

I hate to repeat this every couple pages, but the #1 point of these is not all about ROI. They are low cost miners anyone can afford to buy and a great way to learn about crypto and how mining works. I specifically build these in order to get new people into the ecosystem, that would have never bothered because A) they cannot afford 2-5k USD mining ASICs, or B) can't even run one because of crazy power and noise requirements. Alot of people also gift these as a way to get people that have never even heard of crypto into crypto.

I say this all the time, but new people and veteran members alike get stuck into the ROI and higher price mania and forget that the only way your going to even ROI on a 2k machine, or expect your 54 dollar litecoins to turn into 200 dollar litecoins is by getting even more people interested, buying, and using crypto. A new user is not going to buy 100 Litecoins, or buy a L3+.

Whats better? The same old 10,000 people using litecoin and about 1,000 huge mining farms mining it all in an endless cycle, or 100k new people all mining with these USB miners and all getting interested and buy/using Litecoin?

Hope you get it now Wink

I empathize with you but its freakin' god___ blank annoying when a new person reads about this and they are all SOLD OUT!! Can't even get our hands on one and our meaning me! (Plus a lot of other new people I'm sure)...just sayin

Im working on scaling up production...im a one guy shop, and I don't have the resources to risk making a massive batch that I can't deliver. Which is why the first batch was relatively small, but as soon as the first batch is shipped out and everything goes smoothly ill be able to ramp up fast.

Have to keep in mind that the main bottleneck are the ASICs...I secured as many ASICs as I could afford, and all of that came out of my pocket with zero pre-order money. For second batch ill have more capital to work with and be able to order a larger number of chips.

If you didn't get one there will be another chance!

hi. i want to reserve 10 of the moonlander 2

Thanks both. I put in an order for 2. Will report back how it goes, when I get my miners.

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!

I didn't have time to follow up much, just read up the latest news and it's looking very good, I like the design.
Glad I ordered a batch from AsicPuppy, nice hardware coming home soon.

Quick update for you guys!

So finally got ASIC ship date from packager. They are expected to be delivered to me on the 30th (there was about a 1 week delay due to the Chinese holiday all week last week). Production and shipments will start the week of the 30th, and I expect the full batch to be shipped out by mid november.

Since I decided to include a fan with these, I reworked the thermal design for it around the fan. There is no point in including a large passive heatsink with a fan, so am now including a pin type heatsink designed for fan induction airflow. This has done wonders for efficiency and max these can be pushed. Looking at about a 10c reduction in temperatures for all frequency ranges, and allows a max clock of nearly 1GHz (I was going to cap the clocks at about 800mhz with the old heatsink). This allows for a hashrate of nearly 6MH per miner (even though I would not recommend running it past 800mhz for stability/longevity)!

Below is a pic of the new thermal design...its only 20mm thick from base of PCB to top of fan, and the whole thing is 10mm shorter due to the fan not being stuck in the back.



Here is a pic of me trying to make the voltage regulator blow up...after nearly 3 days it was still going Cheesy (that was running on a hub controlled by an original Rasberry Pi btw)




Windows binaries are also done, as well as Pi 1/Zero, and Pi 2/3. I will be posting instructions and driver links probably next week for you guys to download and making sure the software runs on your systems (so these will run on Windows/Mac/Linux/armv6/and armv7/8 systems).


Were just a few weeks away and can't wait for you guys to get your hands on these!
