Instead of a specific time component for ramping, it uses a health component - if it's stable above a certain hashing percentage threshold it'll step up, and then once it reaches that equilibrium again, it steps up again.

I haven't tested it out on sticks, but I've seen it take 20 minutes to reach target frequency on a test pod.

What controller are you using? I've had good luck on a PC but the timings are still being tweaked to cooperate with a Pi so that might be causing some of your reset/zero-chips issues.

Right, Oregon. That's probably what I meant by Washington.

The manufacturer is in Missouri, but 419 is based out of Ohio. Other resellers are in Washington, Indiana, California, Texas...

Telling Kano he doesn't know how mining works is like telling Sakharov he doesn't know how fusion works.

Calm down, take a step back, and stop trying to sell yourself to folks who don't want to buy. You've put up all the relevant info and if someone finds it and wants in, he'll follow up. Continuing to argue with everyone about how right you are is more effective at pushing people away.

You probably haven't been around long enough to notice, but Kano, NotFuzzyWarm, HaggsFin and Philipma1957 are among the most helpful, knowledgeable and trustworthy people in this forum and collectively represent a substantial knowledge of mining - software, hardware and mine operations.

Might be worth paying attention to what they say.

I am a small-scale mining manufacturer myself; I don't design chips, but I do everything beyond that: circuit and board design, firmware programming, PCB population and testing, even metalwork for heatsinks and housings and I have a driver programmer on retainer. And they are the guys I ask for advice and opinions.

It doesn't matter whether we believe you spent two years working on an ASIC design or not. What they're all saying is, nobody here will buy into the promise of a miner so far in the future, especially one without working samples or even a known working chip. They say your offering looks like a scam because it does, because similar claims with similar bodies of evidence have been presented here a hundred times before and almost to a one they were all lies. You might be the exception, but there is no way (at this time) to prove it definitively enough for miners to buy in. Even if there was, miners tend to be a short-term-gains lot (as in bitcoin mining, the variables are so many and so unpredictable that the landscape six months from now is impossible to rely on) and won't bank on the kind of hardware available in a few months let alone the end of next year.

If your project is real and comes to fruition, that'll be very exciting. But you're asking for trust from skeptics, whose skepticism is built on the reality of having watched scams come and go on a near-weekly basis for most of the last decade. Talking to a miner manufacturer or someone else with the technical competence to verify your work thus far, the capital to continue it, and both the willingness and ability to absorb the loss should it fail will do you better.

And feel free to come back and rub our noses in it when you do have demonstration hardware. We'll all be excited to see the thing work. We love hardware, and everyone enjoys a good underdog success story, so keep us posted on your progress. But please don't underestimate us, the well-established members of a technical community, and please don't be offended by our initial low estimation of you, who comes in with no reputation or credentials to make some pretty tall claims. Trust must be earned, especially from people who have been burned before.

Because some people only have one or the other, and supporting both only added like twenty cents to the cost so why not.

Why would you need both a 12V fan and a USB fan?

They're both pretty much the same. Both would allow you to run six NewPacs at ridiculous speeds, but the 8-port would allow you to also run a Pi controller or USB-powered fan at the same time.
Assuming you had enough 12V coming in for all of that.

Tell me you got a fan on it.

Nuclear power in the US, since we are still using 1960s technology, isn't that great. Most of the issues regarding shutdowns for refueling, and even the types of waste generated, were solved or at least progressed substantially in the last 30 years or so. But because people here are poorly educated about all of that, we keep being afraid of mostly nothing and haven't licensed a new reactor since Phil was probably in high school.

Chernobyl was a deliberate disaster caused by idiots with poor designs and safety measures turned off. Entirely man-made and basically impossible under any other conditions.
3 Mile Island's second reactor is still operating today.
Fukushima survived an earthquake almost a full point larger than it was built to withstand (among the strongest recorded), and then a tsunami, and still almost worked out. The meltdown issues they had were exacerbated by an older reactor design without some of the essential upgrades everywhere else in the world (except maybe Russia) implemented decades ago, and wouldn't have happened at all had the backup generators for redundant cooling pumps not been under several feet of salt water.

Nuclear would be an excellent carryover to getting rid of coal/gas while still improving the tech and infrastructure for a purely renewable grid.

Right now it's impossible for anyone anywhere to buy this. The first batch I would like to keep US-only as much as possible, because we'll still be working out troubleshooting and tech support procedures and if something goes wrong I'd rather it went wrong with someone who spoke English and lived within ready mailing distance.

A comment on USB.

As implied by that these are built on NewPac tech, this board features Bitmain BM1387 (S9) ASICs. Bitmain chips don't have much of a work buffer, and when initialized each chip in the data chain is addressed in such a way that the nonce range is divided up somewhat evenly amongst them. If I understand correctly, the address basically becomes the upper-byte starting point for each chip to parse the 32-bit nonce range. Once that range has been exhausted, in order to prevent wasted work, a fresh pile of data needs to be sent in pretty quickly.

USB2.0 can transfer enormous amounts of data rather quickly using bulk transfer packets. However, the number of packets of any size transferred per second is limited. Because Bitmain chips can't pre-buffer work, and because each chip gets a portion of the load (as opposed to say Innosilicon chips, which can buffer two unique work units per ASIC), fresh work has to be pushed in in fairly small increments rather quickly. This uses up a lot of really small packets, and maxes out the limits of the bus at around 800GH. I think this is the maximum hashrate one could achieve even with multiple devices on the same hub.

When ASICBoost is enabled, the amount of work data delivered to the chips increases slightly but because each work unit is fully parsed with four unique midstates, the practical effect is work units only need to be updated one fourth as often. Because of timing constraints and increased packet sizes, VH's implementation updates work about 1/3.2 as often, so the maximum hashrate from a single USB connection is roughly 2.6GH which means two or three pods should be able to function at high speed off one hub like this.

Limitations like that are probably a primary reason why Bitmain shifted to a fancier controller board with an FPGA buffering work and doling it out on multiplexed serial lines. When a 32-bit nonce range is divided amongst 60-70 chips it gets burned through pretty quickly.

For future higher-hashrate projects we'll either have to look into board-level work buffering to ease the USB load (and require some pretty fancy firmware) or work with different chips with a more bus-efficient work buffering mechanism (like almost all of them besides Bitmain).

You'll have to be more specific, because I have no idea in what case a USB splitter would be useful for this device.


Ok, question edited for more clarity. Using my hub would be kind of a waste, because this guy draws almost exactly zero power from USB, but yes given the limitations of USB I believe you should be able to run at least 3 up to absolute maximum speed from a single source. (assuming ASICBoost is enabled, which is required to reach top speeds anyway)

The power light is orange. My primary PCB supplier doesn't have an orange soldermask option and arranging it would have been super expensive while also going mostly unseen.

Price is TBD. I'll probably be doing more coordination with resellers regarding an MSRP and the like but those negotiations largely haven't happened yet.

As far as I know, no KYC (or fried chicken) is required for buying from anyone I distribute to.

I may open limited direct sales on these, depending on who I know that needs a job, but won't make any promises. For now the safe bet is to talk to your preferred reseller.

I know what you're thinking. This post is going up April 1 and you can't trust anything you see on April 1

Well you're wrong.



(homemade samples of case branding/labeling)

I still need to do some fine-tuning on the housing, and slap a big fat logo on it, but this here is a fully functional prototype of the all-new Terminus R606, building on the work of both the R808 and NewPac USB and progressing in secret since January.

The theoretical peak hashrate of this guy is upwards of 1100GH but that's not guaranteed, and may require a fan upgrade.  This fellow is designed for cool, quiet and convenient. Worry not that it's a wimp, though, because the stock settings should get you upwards of 600GH (close to 700GH with ASICBoost enabled) from a 12V 5A power brick. My tester is pulling 820GH from 12V/6.1A right now with a heatsink temperature of 50C and I almost can't hear it running.

R808 users will notice a few obvious improvements over the original. First and foremost, it's completely enclosed. Makes it quite a bit safer and easier to handle, for sure. Second, dual heatsinks. Cooling is much more effective. Third, standard 80mm quiet case fan is easy to upgrade without having to track down exotic hardware, and it also cools the Vcore regulator for improved overclock stability.

The familar jacks are still present - USBA 5V output for powering a small controller, plus 12V in from a barrel (8A rated, upgraded from the 5A jack on the R808) and 6-pin PCIe. Next we've got a nifty new feature, push-button voltage control. Instead of having to turn a knob and guess at your settings or dig for a meter, now you can adjust from 390mV/chip to 460mV/chip in 10mV increments with the push of a button, and your current setting is counted off on the 3-bit binary LEDs. (yes there'll be a user guide with further details on this feature)

This is not a for-sale announcement, but we're prepping to start manufacture literally right now and they should be shipping soon. I don't have any in-house sales rep this time around, so talk to your favorite reseller and let 'em know you're interested.

If ASICMiner hadn't fallen apart before the BE300 got past engineering samples they'd have been the best thing on the market for several months. Demonstrated efficiency was better than the S5, with bottom clock almost on par with the S7 which rolled out nine months later. Those chips are the reason I started building miners.

ASICMiner's problems were managerial shortcomings, not technical. Bitmain's problems are managerial overreach and greed. Different problems, different people.
