Who likes pod miners?

Whoops I must have forgot to mention I have a new pod miner in development, the Terminus R808. It still uses BM1384 (8 of 'em, hence the name) that should run 100GH off a 12V3A brick and 140GH from a 5A brick. Haven't fully tested yet but it should run that 100GH without a fan (turn it on its side for improved convection), and it has adjustable core voltage and built-in 80C thermal shutoff. At four inches square, it's the smallest not-stick Bitcoin miner made in what, two years?

Everything works except the main Vcore power is misbehaving so I'm redoing that part from scratch. The new layout is already done and I'll be sending off for prototype PCBs tomorrow. It also already works with VH's current cgminer build.

My test unit (running off a hacked external buck) is hashing away at 250MHz (110GH) as seen in the link above.

needs a fan to cool it?

Nice...is the voltage adjustment (potentiometer?) with that tall black 'structure' on a green base?
I have a 70W14A block (from Superpag)  
from left: mini usb? next to the right-Ethernet looks like some alt power connector, maybe? USB B type?
I have some usb A to USB B cords from legacy equipment.

[NotFuzzyWarm]

Lookin' sweet!
Ok, I'll wait and won't hack a hub to supply moar power for 2Pacs's/Compac...
@ Biodom, yes, is a barrel connector for power. USB is coms only as I recall.

actually, i would think that there is a mini USB on the left for coms, but both USB B and barrel are for power, but let's await a word from the man.

Well until he pipes in, with him saying

100GH off a 12V3A brick and 140GH from a 5A brick

pretty sure you aren't gonna get 12v from a USB jack

[sidehack]

It's USB-B. Legacy? Surely I'm not the only one who still uses B. I prefer it to all newer versions. But there's also a mini on there for folks who'd rather use that. I like giving people options.
12V power from a barrel connector, so any kind of 5V supply will be basically useless. This draws zero power from the USB bus. USB for power on a 30-60W device makes no sense. (Please don't bring up USB-C, that's clearly not what's going on here.)

well, sure, brick is a barrel, but I recall that USB power might have been an option (..and I was wrong).
maybe brick for superpag is a wrong one (i just checked), but Plugable's brick has 12V 5A coming out in a barrel, so why not?
i am not talking about using the hub itself.

[QuintLeo]

Zoomhash used to sell 12v 10A bricks with a barrel connection for use with Gridseed "80" units (1 per board so 2 per unit).

I think I've seen higher, but that 10A is pushing the limits on a single barrel connection IIRC.



 Where are the mounting holes though?

[Dibblah]

Congratulations, it looks really good!

Selling these directly on ebay would seem to be possible these days, given that Eruptors (!) are going for upwards of £20 each.

[leowonderful]

This unit is looking absolutely amazing. I'm even more surprised this miner can be run passively cooled- what's the temps like on the miner if you do so? If I ever got my hands on one I'd definitely put a fan on it, that's for sure

[valkir]

Wow! Nice update! Can't wait to get mine. 

[olseh]

Hells yeah! Looks the goods man!!!

[sidehack]

I changed my original design a bit because the ability to run 100GH passively cooled was specifically requested; this enlarged the topside heatsink and added the bottom sink. The original plan was to have the heatsink topside only and smaller with a mounted 50mm fan. As it is, a fan will be optional. My test unit has a single about 60mm CPU cooler fan and only the topside heatsink and it's comfortable at top speed (300MHz). The board does have a fan header (12V only, no throttling) but it's not populated on the one photographed, guess I forgot.

The core voltage is intended to allow up to 300MHz stable, which should about max out a 60W brick. I could build it to push more power if you had a higher-current brick, but above about 300MHz the BM1384's efficiency curve gets pretty steep so your heat per additional hash gets crazy - note the difference from 100 to 140GH is already almost doubling the power use.

I probably won't sell directly on eBay. I really don't like dealing with people, I like designing and building and not being bothered. I'll sell on here where people tend to be more intelligent and articulate than the average internet hooligan and let CrazyGuy, HolyScott, MacEntyre and their colleagues take on the grumbling masses.

Also, I intend to keep this formfactor around. If we can ever get Bitfury stuff working, there'll be a 6-chip Bitfury Terminus R606. It'll be orange.

[nuanicaj]

what will these units cost?

[sidehack]

Straight from me, I'm thinking $65. Resellers will get volume discounts as my way of saying thanks for handling all the customers I don't want to spend time on.

There'll also be the option to trade S5 parts, like I had set up in hopes of the Biggie pod. There'll be no Biggie pod, but there will be this guy. The Amita full-size pod line, for which the Biggie would have been a form-factor flagship and the Bitfury version will have 11 chips, is still planned but won't see the light of day until Bitfury chips cooperate.

[AJRGale]

Ohhh Yeah, this is what I like to see! how big are these? can I shove 2 inside an old rock-box?

[Biodom]

Ohhh Yeah, this is what I like to see! how big are these? can I shove 2 inside an old rock-box?

see OP=4 inches square, not sure re height.
At first i thought that i see a reflection of the top sink on the table, but, apparently, there are identical sinks on top and bottom with bottom one being a bit blurry on the pic.

[Kuulani]

Nice work Sidehack, They look awesome! But... does it have blinking lights

you see, I read over this about 5 times, I was looking for numbers, not words and it was 1am too when I type that out, 3am now lol

just pulled out an old board, and cannot find my ruler.. so yeah, I say 1.75 of them can fit
