There are several different types of Bitcoin clients. The most secure are full nodes like Bitcoin Core, which will follow the rules of the network no matter what miners do. Even if every miner decided to create 1000 bitcoins per block, full nodes would stick to the rules and reject those blocks.

The four Terminus miners will be shipped out today. ooeygooeygold never got in touch so his bid was cancelled, which shifted the fourth pod back to xhomerx10 who paid promptly.

Seconds 2Pacs are still available. I'd like to get at least $25 from them, since they're fully functional and passed all the same tests, albeit at a bit higher core voltage (typically 1.3-1.35V versus 1.25V) which can change the efficiency a bit. $25 covers materials and labor and puts about $10 in the donation.

Cool, quiet and up to 1TH pod miner, on sale now!

PMed you about this, have yet to receive a reply.

Actually you PMed me a question barely peripherally related to this whose answer could be found with about five seconds' use of the search function and I tend not to answer questions like that. I don't like doing other people's homework.

By the way, I forgot to mention but these pods work with VH's cgminer. You'll want --gekko-terminus-freq to set the speed. It runs 0.44GH/MHz so 250MHz gets 110GH.

I will take three (x3) at $25 each if still available, & will also include an extra $10 to help your friend (0.0395 BTC total, currently $85.95)

I've been playing with my proto-pod and 2-pacs for a couple of days now.  Lots of fun and no profit! (I knew that - going for a lottery win)
I was using a 12V 4000mA power brick with the 5.5mm barrel to alternately power my USB hub and the pod but I never pushed it above 175 MHz for any length of time because I didn't want to brick the brick Wink
Eventually, I dug through my big old box of electronics that I never use anymoretm and I was able to find a 12V 5000mA brick with the right sized barrel plug!  Now I'm able to push the proto-pod to 250 MHz but I'm pulling a little over 65W at-the-wall.  I'm just wondering if the 12V 5000mA brick can handle that type of input power continuously.  I'm unable to find the specs for efficiency on it - it's a FlyPower model PS60IBCAY5000S if that helps (and I already did the google search but found nothing about efficiency).  I plan to order a better brick since they are impossible to find at electronics shops around me but meanwhile I would prefer not to melt anything Wink

Keep a fire extinguisher handy.

Measure the actual output to calculate how loaded the brick actually is. I'm sure that you probably already know this, but as a general rule of thumb running something long-term over 80% of it's rated output is not recommended. Consumer grade stuff even more so.

That you are pulling 65W at the wall may just be an inefficient power supply.

No mining at the moment.

 I can't measure the output of the brick but based on the specs here for the 2-Pac I was thinking it should be around 4 X 10.11 watts @ 250MHz plus the two little fans on the heatsink (probably 2.5 watts for the two of those) - I was thinking 45 watts.  Just powering up the pod, I'm seeing about 8 watts at the wall then when the hashing starts it ramps up to 62.5 watts at the wall.  I know sidehack said it should run 110 GH/s on the 5A brick but when I saw the draw at the wall, I got a little concerned... maybe you're right and it's just an efficiency issue.  Guess I'll tune it down a bit until I get a better brick.  Thanks!

I posted an update in my Pod Miners hardware thread regarding the most recent revision of the Terminus PCB. Long story short, the support controller doesn't work how I'd like so it's going to take another slight revision to get all the features implemented. To explain how slight, know that I redid it all in the PCB layout program in about 15 minutes.

The end result being, depending on whether or not all the mining parts (which were almost wholly unchanged from the board revision sold in this auction) work as expected, I might have another dozen or so of these pods going out if I can get 'em all to work.

If I do, I'll probably open up another auction thread once I have the final head count, with a more traditional quantity@price bidding, and split the final take with Laura's donation.

The new revision won't be quite as jankety as these, since it integrates the tacked-on buck module by design. The fan mounting will also be better.

 I didn't but I took one to show it off Wink



 Personally I think the "tacked on" buck adds character.  It gives it that homemade look Wink  Also, it appears you used high-quality parts.
