Don't understand the hate. put them up for 99 cents, no reserve. People in the European and Asian market want these too and didn't have the opportunity to buy them from sidehack. I was adamant about following this thread so I could be one of the first ones on the list, checking it multiple times a day. Almost everyone bidding is from Europe or Asia.  US buyers already know to buy them from sidehack, European and Asian buyers never had the chance.

European buyers can get actual EU-legal-and-approved ones from bitshopper.de and Asian customers only don't have them because they didn't ask.

You are responsible for customer support, though, don't forget that. My general policy is I provide support to your customers only if you fail to do so, but if you fail to do so you stop being one of my customers. Fair's fair.

I agree 100%.  Tech support is open almost all hours of the day, as said in my listings.  All my units are tested working on my rpi3 setup and ran perfect for 4ish hours. Wouldnt want to stop becoming your customer, as I am an avid lover of your miners Smiley

We'll have some for EU customers but not that fast as you may expect. Problem is: Due to legal constraints a housing for the PCB is a must to fulfill WEEE and EU electronics requirements. We have already housing prototypes but before we order the production version we must be 100% sure that everything works as expected regarding heat dissipation and air flow. Then we have to register it for WEEE, wait until it is confirmed and then we can start sales.

Thank you for the detailed answer. Can you say what is the estimated price for the Terminus PCB with Housing?

That really sucks.  Glad you have such a good handle on it.  Good luck.

So, at what MHz can we reliably run these pod miners at? It sounded like to me, 8 chips at 9W is 72W. 80% of 72% would mean ~7W per chip? Not sure what that translates to in terms of MHz.

According to this... maybe 175 MHz is reasonable?

From the Q/A section of the first post of the Terminus Support Thread:


Q.  How fast do these things mine at?

With the default settings, this miner should produce 66Gh/s @150MHz.  more details


The "more details" link above gives us:

100MHz (44GH) 660mV/node 2.64V total; 12V 1.4A for 16.8W/0.38J/GH
125MHz (55GH) 660mV/node 2.64V total; 12V 1.7A for 20.4W/0.37J/GH
150MHz (66GH) 660mV/node 2.64V total; 12V 2.0A for 24.0W/0.36J/GH
175MHz (77GH) 693mV/node 2.77V total; 12V 2.5A for 30.0W/0.39J/GH
200MHz (88GH) 715mV/node 2.86V total; 12V 3.1A for 37.2W/0.42J/GH
225MHz (99GH) 755mV/node 3.02V total; 12V 3.8A for 45.6W/0.46J/GH
250MHz (110GH) 770mV/node 3.08V total; 12V 4.4A for 52.8W/0.48J/GH
275MHz (121GH) 770mV/node 3.08V total; 12V 4.9A for 58.8W/0.49J/GH

I think 275MHz is reaching the upper limit of the main regulator.

I guess I forgot a 2Pac is two chips... so 8 chip miner is like having 4 2Pacs.

How effective is the cooling when you get above 150MHZ? Do you need external fan or at what point do you need extra cooling to be used?

From a hashrate perspective, yeah. However, the power systems within the miners are different. The 2Pac has 2 chips in series so the main regulator has to double the voltage but not the current. This means the regulator, which is rated for around 17A, can push the chips well above 400MHz if you can keep them cool. The Terminus is 8 chips in series pairs, so it runs four times the voltage and double the current. The main regulator is limited to 20A, which means 10A per chip, hence why it can't hit the higher speeds like a 2Pac can.

I could have made it faster by adding in more series pairs, which increases the voltage but not the current. The practical top-end here is about 7 pairs (limited by the regulator's maximum output voltage). Adding more chips would require a larger board, larger heatsink, more fans and make the whole thing more expensive. The practical limit for this size miner is 8, maybe 10 chips.

Before shipping out, every Terminus pod is run for 1 hour at max voltage and 200MHz.

On the next one I'll be using a custom main regulator that should be good for more power, and of course it'll have more efficient chips so a much higher hashrate will be attainable. Also it'll integrate software voltage adjustment so people who don't have meters and screwdrivers (which is to say, lame people) can still do the tweaking.

Product-specific questions should probably be addressed to the support thread, now that a product-specific support thread is available.

I have been running the two pods that I have at 225 MHz for about 2 weeks now with zero issues, they are in a controlled environment and temp is set to 60 f.
My avg hash rate is 195 Gh/s at the 225 MHz on nicehash.
These two are solid work horses, they are slightly warm to the touch.

Problem is: Due to legal constraints a housing for the PCB is a must to fulfill WEEE and EU electronics requirements.

just wondering...

how come that you can buy hundreds of pcb types, arduino's, raspberry pi's etc in an electronics shop/webshop that doesn't have any housing?

that stuff was imported too without any problems.

They don't import the PODs, they build it, then need to use the 'legality'...

Me too i like but in order you to become miners you need to prepare expensive CPU that fit to the requirement in bitcoins miners. The power supply needed most have UPS and protected from any power faillure. and many more.

Just got my Terminus, works just fine so far. Just wanted to say thanks for an excellent product and a great collectible to sidehack! Can't wait for your Bitfury developments.
