Announcing GekkoScience's new USB stick miner, the aptly-named NewPac

[minefarmbuy]

Thanks got my order for 10 units tracking..  

Nice, hopefully all the bugs are finally worked out for our auto-notifications.

Try not to destroy these. I recommend leaving the voltage stock and using a fan.

Please set them to be high.

Please set them to be high.

In case the original comment didn't register.

Leave them at stock, you'll end up destroying the stick otherwise.

Potentiometer @ 3 o'clock can run up to 500MHz.
The default is at about 4-5 o'clock.   You can run up to 600MHz+ there.   Don't change it.

Again, It is highly recommended you don't change the default voltage.

The one I just received in the mail was cranked all the way up, and quite obviously heat-damaged with a lot of discoloration on the PCB.

Leaving the voltage at stock and using a fan will prevent this. Taking better care of your stuff means not having to replace them all the time.

I have an AC fan cooling them down running at 250mhz.

Thanks see that my units have shipped.

Even at stock speeds I'd run a fan on the newpacs. 70-90 CFM should be fine per GS Hub.

Just received my three NewPac's and the new Gekkoscience Hub

Arctic cooling USB fan added to the hub

All I can say is "WOW"

All put together along with the updated software from vh, painless as always

Running at stock speed and fast

Perfect combination of hardware

Running mine with GS hub on 600 and 550 of course with cooling. Hardly any Hw errors stable for weeks already with 135 GHs and 125 GHs
Indeed great hardware combination.
The stick @ 550 wasn't able to go that far @ first, 400 was max. Did turn potentiometer about 20 degrees (did turn in little steps), now stable @ 550 and not overheating at all.

Only things i did not figure out yet, was the boost option. CGminer (v4.11.1) won't start when i am using that option.

[sidehack]

Won't start, or won't connect to your pool of choice?

won't start, screen stays black.
When i remove the newpac boost option, its all fine again.
Tried putting it @ end of line, @ beginning, @ middel, no effect at all

Could it b the pool i am mining @? Does the pool need to support the boost option?

[sidehack]

I think there's a known issue with enabling AB on a non-AB pool. It changes something at the protocol level so it won't even connect properly. Not sure if that's exactly what you're seeing but it could be. Check to make sure your pool supports ASICBoost.

Found an whitepaper about asic boost https://arxiv.org/ftp/arxiv/papers/1604/1604.00575.pdf
and website of the inventor of asicboost

Edit: seems the people behind this info are doing it with other people ideas.

[sidehack]

Okay great, but that doesn't have much to do with the specifics of driver implementation.

[minefarmbuy]

No offence to Bitcoin's, but I only know one whitepaper with a use case in my house.

Also, I haven't tried current software but never was able to get asic boost to work with winX builds. Still you're not losing as much with a stick miner compared to industrial asics. Hopefully I get more time to troubleshoot again.

Asic boost is an option that has to be supported by the pool. The one i am mining on is not supporting it, clear to me now.

yup vh did an amazing job with the driver, the newpac runs very stable even when running more than 10 at the same time
Gekkoscience's new 8 port/7 port usb hubs are another level quality and build too IMHO

Just to keep the Record straight:
The company asicboost.com is NOT the 'inventor' of AB. They are a holding company that bought the AB Patent from Dr. Timo Hanke. The company was created to leverage the AB patent as a way to get IP rights from miner manufacturers by using what they call a "Blockchain Defensive Patent License". Thankfully so far they have failed miserably at that. btw: Their only listed Contact is through a Law office in Chicago.

Even Dr. Hanke is not the inventor of ASICboost: Many if not most parts of the AB logic processes and code were created by other developers (Kano is one of them) as speed optimizations originally aimed at CPU then later, GPU based BTC mining and discussed here in the Forum at least a year or more before Dr. Hanke applied for his Patent or published his paper. Kano has made mention of contributing such CPU/GPU code mods back in 2013 (edit: Citations needed). Dr. Hanke was only the first to publicly put it all together targeting it for use in ASIC-based SHA256 processing chips, have the concept (now being hardware-based) published in Academia as a whitepaper, and managed to get his version of AB Patented as such.

edit: Interesting -- I take it the original AB Patent has been revoked or at least suspended while being contested. Checking the AB site they now state that it is Patent Pending whereas previously when they and Halong Mining appeared on the scene back in November 2017 they unequivocally called it Patented. Even more interesting is that when you click on the link for their Blockchain Defensive Patent License, FireFox blocks it stating the site is improperly configured -- given the folks who are suspected to be behind that onerous, IP-grabbing patent license, their site attempting to do something shady does not surprise me in the least.

Gekkoscience's new 8 port/7 port usb hubs are another level quality and build too IMHO...

Are you saying that the 7-port is not the best choice?

[sidehack]

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.

My power source would be your breakout board for a HP-DPS800, if I can find it. So it can't run a PI controller and a 12v fan and USB fan?
