No I just have the barrel connector that came with it. It's loose at the part where it connects to the pod.

I'm interested in the pin connector. Looks like more work and cost but may be better for my last little guy. I ordered a few and he's the last one standing. I upgraded the fans, so maybe a power supply is next. You have or know of a tutorial for how to set that up?

I'm also going to start a setup with a bunch of newpacs. My goal would be getting them and the terminus running off a single pi.

Just watch out for the pi USB bandwidth. They can only support a limited number of miners running at a time, ASIC Boost will help greatly with that, but that's even a little buggy still. (you can read more about that in the newpac support fourms)

Okay that's pretty balls. I built the darn thing and I've never got one to run 300MHz. Nice.

By the way - the barrel jack on the R808 is only rated for 5A, so a peak of 60W reliably. I'm looking at an 8A-rated part for a different project and if I like it we'll probably use that exclusively on anything needing a barrel in the future. Might be more sturdy.

What RockMoney says is correct, the powersupply from parrellels is a great deal, thats lower than even my costs. But if your running on one of our 7A power bricks, they are solid. We imported them in from China specifically for GekkoScience products and they went through rigorous testing before they were approved, yes even by SideHack.

Long story short, I was asking because if it was one of ours, we have full warranties on all our products and would be happy to replace it for you at no cost.

New issue cropped up on my pod - anyone have advice?

I am using the brick power supply and the connecter gets loose. Unless it sits just right the unit turns off. It happens about once or twice a week and I have to jiggle the connector to get it to work. Any way to tighten that up?

You could change that power supply out for a much better, server power supply! The terminus already has a 6-pin PCI-e connector, and using something like a HP 460 Watt or 750 Watt Server PSU with breakout board will solve your current problem, and is a much better power source in my opinion! My cousin has a terminus and was unable to make it run steadily at higher frequencies. I sent him a HP 750 Watt PSU with board, and now he can run his terminus at 300Mhz with ZERO issues!

Although 900 Watts/1200 Watts would be overkill, 419mining has a kit available here: https://www.419mining.com/shop/power-supply/complete-power-bundle/.

HP also make 460 Watt and 750 Watt models like this one on Amazon: http://a.co/d/eHrC9Rl for only $15.00 USD.

You will then need a breakout board like this for only $7.99: https://www.parallelminer.com/product/x8-breakout-board-adapter-compatible-with-hp-750w-1200w1500watt-hp-power-supply-copy/.

Lastly, you will need a 6-pin PCI-e cable like this: https://www.ebay.com/itm/27cm-6-Pin-Male-To-PCI-E-6-Power-Extension-Cable-Video-Card-18AWG-Connector/292828225339?epid=4026270229&hash=item442dec1f3b:g:Hs0AAOSw8R9b9m1q:rk:9:pf:0

Or, you could buy a complete kit for $35.00 like this: https://www.parallelminer.com/product/gpu-mining-power-supply-kit-hp-750-watt-80-gold-psu/

For $25.00 and free s&h, you could buy a brand new HP 750 Watt Server PSU with brand new Breakout Board and PCI-e cable from me. Anyway, there are so many options besides the ones I listed, and I'd be willing to be that you would be much happier powering your terminus with a server power supply that was built to run 24/7/365.

Hey MinerBobbert, is it the Terminus or the Brick that is having issues?

Are the cooler master 50x50x20 fans what people are upgrading the "stock" fans with?

from a few posts back:

These got these fans on recommendation of another uses. https://amzn.to/2xvCzZh
You also need to get longer screws.

Okay, but don't forget that the limiter is heat in the main regulator. Depending on heat, it could cut off at 15A or so, which is only about 6W per chip.

Also, that's a lot of finagling. I'd say once you're taking stuff apart it becomes "roast at your own risk".

I fixed that problem, added a heat sink to the bottom of the board and simply air cool my pods with a common fan. So far it's working quite nicely. What I did was lay a bead of high temp epoxy around the area, leveled it, let it set. Then I filled the center with heat transfer compound, lay another bead of high temp epoxy and attached a heat sink. Not perfect, I would have preferred a compression seating, but it doesn't let go.

I'd be interested in the box design. Would we need two fans to pull and push air out of the box?

PM me and I will send you a jpg, hand drawn of course for now, but you'll get the general idea. I use 2.5lb soundproof foam for my noise suppression systems. Makes the box a bit bigger but if you have a dual fan arrangement on a single rad like I do, you are working with 18" wide by 12" high and about 20" deep. The ducting is set up almost like a subwoofer using a right angle baffle as the air intake. This way you can pad the air intake and exhaust with sound insulation and mount the pump inside on either springs or rubber bushings. Rad and fan also mount inside about 6" from the right angle exhaust duct. I keep reservoir outside.

As long as it's still mining, the issue is cosmetic. Flakey signal pin on one chip.

Good news! Thanks. Move along, move along. Nothing to see here.

I have a couple T808s that have been chunking along nicely for a few months. Recently while checking on them, I noticed one had the white lights on solidly, not blinking. I halted the mining and cycled the power. Upon restarting the mining, it appears to be mining well. The hash rate, hardware errors, and such all look to be within spec. Anything I should do or be aware of?

Thanks,
The Nerdy Type

We are not retail.

I was looking up some fans this morning. Can hear the ball barrings on one of my units need some love.

5cm. Somewhere back a few pages someone put up an Amazon link to a taller fan that fits and reportedly does a better job cooling. Might also have to track down longer screws.

So it looks like one of the fans of a pod is giving up the ghost on me. It was one I had pre-ordered way back when. I figured I'd ask, where might be the best place to source a replacement fan? They're what, something like 4.5 CM square?

I had figured on putting the new one in a case at the factory.

Ya, i figured I could make something that would "snap" on the side of your case.

Cool, thanks. I've been looking for a HP power supply. @jstefanop announced a scrypt miner so maybe I can run my Terminus R808 and Apollo on the same power supply! Wink

these do look kinda awsome, Ive been tinkering with a raspberry pi/R808 combination that would work the same way. I dont want to produce the new 3d printed case though till I get ahold of the new model from sidehack
