Topic: Hacking KNC Titan / Jupiter / Neptune miners back to life. Why not? - page 13. (Read 76765 times)

So I plugged in asic 3 board, it has issues also.
 
If I plug it in it is the reason the jupiter hangs after a few minutes.

When that board is plugged in either with the others or by itself the Advanced page hangs and does not display then after a minute the whole miner just locks up.

But it seems to hash ok until it locks up.

Before it locked up it has errors under waas.

I have asic boards 1, 4 and 5 plugged in.

Soooo whats up with those errors?

If I plug in the fourth I get an unresponsive jupiter after about 5-10 minutes.
 

I can login via ssh now.

I logged in as root using the admin password.........allowing root login via ssh is not good security.

I gave the jupiter a new network name so it would ask to save the key, it did but it still gives permission denied if I try to login via ssh.

So I changed the default username and password, still cant log in.

I can log in via the web gui just fine.

Also unplugged three of the four data cables and am now just running on asic 1, the one with the two dead dc/dc converters, still working after about 15 minutes.

Ok asic 1 ran for about 20 minutes with zero issues.

So now I'll unplug it and plug in asic 5 for a while.

Meantime I just took a look at the latest litecoin price.

Well I have a few issues,

Can't login via ssh even tho its enabled.
After about 10 minutes the web gui gets unresponsive and the heat sinks get cool so i'm assuming its no longer hashing.
Most of the time I can not access the "Advanced" tab on the web gui.
Looks like I have 2 dead dc/dc converters.







 

Well, how much more profitable does this make Titans? Worth fixing again?

Er ...confused...unfamilar with 'main status page' and/or if you are gonna brand the LCD with your name version like

Lightfoot BBB ver 1.00 (or some such)

300mh

that kinda thing (point me to the link or post for clarity...thanks)

edit $7.85 LTC what I feel like now Just love watching it go up



lol

Pump LTC Pump......the evil KNC Titans need Bitmain's for company!

I believe the Neptune 1.06 code should be able to run a Jupiter board. Give it a try for experiment's sake.

That's why these light up blue, not green. My comments and such are on the main status page.

Be sure to make it so the LCD says LIGHTFOOT BBB mod...(would not want to mix up controllers......and intermingle with them 'evil knc PI boards)

Hm....just got 3 pi qberty boards fixed ....and got 3 neppie cards coming with BBB ..crap...I should now get more

Alright since I have my Jupiter running, not 24/7 just when I tinker with it, what is the best version of firmware to run on it?

 I'm running KNC jupiter-1.01 now, or can a KNC one from a newer miner or a newer one that is not from KNC?

All done, just need a micro-SD card reader to make a copy of the image. Instructions are simple: Write it to a Micro SD card, put it in, boot, set your titan values, and rock. The root password is not set, so you can log in as needed, I'll set the default web account to admin/admin.

The screen will display titan-bbb 2.00, and the light will be blue when it goes solid on (to differentiate this from the usual green LED). You can mine with my default credentials for a week if you want to repay me or send some bitcoin/litecoin to the proper address.

That's about it. Underneath the hood it's kind of a mess, but on the top end it's pretty nice. I should have it posted to a dropbox by Monday or so at the latest.

Truly a man for the people!

Well, I figured it out. Putting i2c-loop in rc.local gets it up and running, but too late for bfgminer which has started and needs to be bounced. So I put a 30second delay in the bfgminer.sh file, that stalls it long enough for the loop to enable the i2c lines properly.

Documenting this takes a lot of time, I'm focused now on getting code out there for people to use (ie: you....). Will work on that eventually.

Sounds awesome, may i suggest asking Henrik about the i2c-loop.sh.

https://mega.nz
dropbox and some others if you need them.

If you managed to document your steps on a fresh linux install, please hand them to me and ill make a guide for you to post somewhere.

Meantime I have been working on the bbb titan code. I've got everything patched so I can distribute this as a .img file and let people extract it to sd cards except I can't figure out how to get i2c-loop.sh to auto start. It's annoying as hell because aside from that everything works now.

Will keep pounding this weekend. What's a good free-file site to post a couple of gig file?

I have like 6 or so Jupiters (5 for the cases etc) I am more then ready for an bitcoin BU fork with a massive difficulty drop ..to jump in on any such scammer bitcoin clone alt!

(prepared I am)

er anyway I used 2 of the cases on these for server PSU mods

https://bitcointalksearch.org/topic/m.15534011

anyway 2580 watts of platinum 94% eff with 15 awg leads for $300 bucks  vs corsair 1200 watts PSU on newegg (on sale 1x a month) for 300 bucks and 16 awg wire

worked well for me on the knc titans.. at having 7 of these server psu rigs...that was 2100 bucks in savings for the same psu platinums at 2x the power and NO need
for knc y adapters anymore with 15 awg wire.(yech...they suck) thus NO burnouts

anyway cases are fun hacks...as long as we are revisting KNC jupiter's on this thread

Wow. A bitcoin miner that has 2w/gh efficiency. I remember when that was a massive step up from the 4w/gh of the Bfl Jalapeno which was light years ahead of the 10w/gh or so of the old stick miners.

Fun stuff....

Old radimax 1200 w power supply's cables are getting pretty warm.
