They fit between your Titans Raspberry PI and the controller board. It has some reinforced copper to prevent burning out (which a lot of bridges did do). You can get them if you have burnt or broken bridges, or if you want some just in-case your controller's bridges fail than it's nice too.

what these bridge do
??

Okay sold 3, only 4 KnC bridges left. Again, pricing is firm at 0.5 BTC per bridge PCB. If someone wants a bigger amount than 5 bridges just PM me, there's two other guys that want more than 5, we can pool all the resources and just get a bulk order for the amount you want.

Here's what they look like fresh off the line.

I dont think this should be aproblem.

But i did read that someone have alreaady tried this whit KNC SHA256 boards and have failed, would be possible whit some hardware modification.


On this treadh someowere i think i did read that somone took a R-pi from titan whit bridge to a Neptune board, but The Board is unable to find the cubes.

I do not remeber who did this but should be somewere if you look around 

OK as a project to test WITHOUT A CUBE...assuming one can get a clone titan bridge (i have one on order) and supposedly a JUPITER OCT controller with 4 ports also works ..I also have that...and a spare LCD screen from Titan controller (have 6 on a controller 2 on other titans controller) and of course put the Firmware for Titan on SD card and I have a 'supposed' correct Raspberry PI B+ 512mb as well

So ...assuming my bravery factor can be 'pushed' up somewhat on this ...(donations? naw people don't go donations for stupid) anyway

I take 4 port oct knc Jupiter board....put clone bridge on it.....put raspberry pi on that....add the tarky titan firmware on the SD ...pop the LCD in (not sure what port does it matter) and then just simply SEE if the LCD at least shows Tarky Titan and looks like its looking for a cube...and ie be able to IP into it via putty and GUI and  showing NO cubes

would that be a good first step before the 'virgin sacrifice' of a even 1 die working Titan cube or some such on this project?

or again ..did i 'miss the memo' and this is not possible on anything say but a Neptune card or nov only knc Jupiter card and not my oct Jupiter 4 port card..and/or the
actual fpga on the titan orig card is different and not loaded

not sure of my bravery factor on the above but just asking if such a scenario would tell the tale? Again with the 'cloned titan bridge' coming...have all the parts staring at me above

Side note: I re-flowed a new FPGA on this other Neptune board... Test results below:

root@Neptune:/etc/init.d# io-pwr init
TPS65217 OK. Modification A, revision 1.1
root@Neptune:/etc/init.d# program-fpga spimux.rbf
dd: can't open 'spimux.rbf': No such file or directory
ERROR: CONFIG_DONE != 1 when nCONFIG is HIGH
root@Neptune:/etc/init.d# program-fpga /usr/bin/spimux.rbf
82+1 records in
82+1 records out
root@Neptune:/etc/init.d#

I think I can officially fix a rainy day. That's 2 for 2 on the controller boards.

again previous msg ..with the savings of combined $45 in my gas budget year round heating price per month due to miners and this winter electric home heating as primary change
I posted previously plan (which again is true 2500w 24/7 in a well insulated 3 bedroom house keeps the upstairs at 64F and downstairs at 61F and basement at 68F) also good
sleeping temps and I'm rarely home for heat to be more then that....anyway with the all year budget gas savings and the 115 bucks about a month on electric savings ..that is a total of
$1115 bucks per year in savings. Some of that also to be noted is savings above and beyond the 'titan asic miners' in this decrease in price from 13.7c kwh to 9.27c kwh applies to ALL my electric use too boot....

So yeah...with the BTC halving coming up in August 2016 a person using the above 'just may' be able to mine at least bought 'used' equipment as a home miner in winter of 2016-2017 yet it seems...or as you state places like USA states with hydroelectric and Texas etc.....

anyway hopefully it is not just me and with a phone call (esp Midwest Xcel customers...again call after hours and a regular xcel tech ...you don't want this passed around during the day to be mulled over..the regular customer rep after hours has the power to 'tag' such as was my case..just saying)

worth a call ..again esp Xcel electric customers...worse that can happen is 1) they laugh and go no....same rates.....2) they inspect your server equip ..laugh say nice try same old rates

hopefully it is 3) it is tag'd by rep ....and someone looks at your electric use in winter ..goes yep looks like winter electric heat is primary..and rubber stamps it ..like in my case

again below is the thread on how this was done on bitcointalk for those too lazy to scroll back

https://bitcointalksearch.org/topic/m.13304401

again good luck...the down side on this is on APRIL 2016 when the rate reverts I am gonna 'cry me a river' it is gonna hurt to go from 9.27c kwh to 13.7c kwh in one swoop for an extra 115 bucks  a month to xcel..my only 'hope' is that BTC and LTC prices have gone up significant for it to take some of the pain away..

if nothing else I saved the above cash from electric anyway (off of titans) of $575 this winter anywary....when our "outer space alien overlord masters' take the Earth over and make this all moot and btc is 'beanie babies" heh well at least you saved that!

I am getting a pretty good year round  price of 9c/kwh and I have it locked in for 2 years. Not too far away is an electrical coop where rates are like 6-7c/kwh. I think the cheapest rates are utilities with hydroelectric power, and probably where a lot of datacenters are located. Texas  has it's own power grid so this contributes to lower rates as there's little interference and regulation from Washington dc.

Not really off topic but 'sorta' ..tripped over how to get your electric bill reduced big time for your miners (maybe)

below is my link to a thread I made here on bitcointalk on how I managed with a phone call and get winter electric rates for my miners moved to the 'winter elec heat' discount

rate. A drop from 13.7c kwh all last year (this is rate/fees/local/taxes/etc or around 2500 kwh or so for my house a month with 2 Titans divided by my monthly bill..ie real kwh costs!)

to the NEW rate (prob thru may bill or 4-5 months) or 9.27c kwh WOW!

With just a 'phone call' NO inspection etc...this may be a 'fluke' but if you are in USA and have Xcel ...look at the back of your bill for this option. I suspect it would also

apply to other world wide folk that during winter may have the same break in price for 'electric heat' option.

Anyway ...as you can see from my 'explanation' in the long post in thread below...I kinda stumbled into this ..and sat on pins and needles for 1 month till today's bill ...but

IT WAS approved...so man a drop from 13.7c kwh to 9.27c kwh is a really really big deal to me $115 usd a month savings.

You add the already $45 buck savings off my Gas Heating Budget plan (compared to before ASIC's in basement) a combined $160 buck a month savings thru the winter for the electric and

the gas was for all year round!

So if i can 'nurse' the Titans into say next winter.....a 'used' home asic machine with what i managed to pull off in the link below may make it profitable for me to "home mine' yet

into the winter of 2016-2017...assuming as we all wish the halving and such in 2016 ...hopefully ...drives btc and ltc prices UP!

anyway for what it is worth ....the link below..hopefully ..this works for you as well as it did for me..if not you are no worse off electric kwh price wise anyway so imho give it

a shot ..use what you want from how I tripped over this ..and good luck!

Yeah, pretty much only first gen ASIC's were the real crypto makers in this game. Everything since then has been a race to make back ROI over a year w/ barely any profit beyond that, and by that time upgrades needed to happen to stay in that race. So, its constantly a cycle of not making much at all LOL! ...

Heh went back to my 1st post on bitcointalk I could find in my posted message area (they had a crash so as far as it could go back) here is the link:

Like an idiot I cancelled the SATURN (damn) but was TOO overextended with not knowing if I'd ever get 1) BFL equip or 2) refund...did get a miracle BFL refund 1 year and 20 days
later thru luck of FTC coming after them (3 week window before the FTC shut them down) ...but in 20/20 hindsight I guess it made sense to punt the Saturn...damn should not have done that!

made 53 btc off that Jupiter....good times it ROI'd in like 3 weeks lol


any other good 1st posts you guys can find in your posting thread from back in the day on here...my actual oldest post is this one in the swedish miner area here

(such a cute clueless newbie I was....BTC at the time/date 124 bucks a BTC or so ...I figured I'd never ROI .....even so happy newbie...boy was I wrong 6 weeks after I got the beast 1100 usd btc)

anyway just thought  it was funny my oldest post on here is the above

others have an amusing 1st post on this thread?

Ah, now makes complete sense ... being that you showed me what an erroneous output from that command, on a bad board, looks like =)

yeah ...i have no balls...i will be gettting one of the cloned titan bridges ....i have a jupiter 4 port board (which supposedly you can upgrade to a neppie so prob would work) and a spare raspberry pi B+ 512 mb (which I assume is the proper PI for the Titan)......sooooooo

All I have to do is take the Jupiter Board....pop the bridge on it......put the pi on it....re-do the SD firmware and fire it up?

or I suppose you could just fire up the above w/o a cube and see if the stuff comes up as a Tarky Titan IP and all with the firmware etc with no cubes?

I suppose you could fry the pi and/or the 4 port board i doubt the titan bridge would be affected?

Alas NO BALLS we need someone with a barely I mean barely working Titan cube to try this with (or send to someone with proper neppie board)

but that is the somewhat 'likely deluded' thoughts about this on this thread lol

as to 'straight titan controller fixes' you should find a few folk on here who need such..fixes  I'd think? (Vegas?)

Cool, I'm up and hashing here with wrecked equipment. More details on this thread.

https://bitcointalk.org/index.php?topic=1283859.20

Next up: Fixing blown Titans. Why not, I seem to be kind of good at this :-)

damn i saw  a 1 die only working titan cube go for 100 bucks on ebay that would be worth risking on something like this anyone have a cube that barely hashes that wants to try this?

I mean even a BAD cube that just kinda sorta works for like say 1/2 hr then dorks out would be enough to test such (imho not that I know squat)

(wonder if VEGAS has such a practiacally 'dead' but not quite Titan Cube... laying about? that is 'unfixable' in a stable manner of any sort but would work for testing purposes?)


I mean SOMEONE on this thread has to have a Titan cube that 'practiacally' is a Titan cube paperweight...ie kinda sorta works but too damn scary to run on their main unit
due to flakyness or inherent knc evilness? It does not (again in my uninformed opinioin) have to run fast on say its one working die or run for long ...just enough to show
proof of concept)...(again i know squat on electronics just saying






Another issue that needs consideration is 'supposedly' you can take any Neptune or Jupiter or Saturn or Mercury board and use such on a Neptune...but the 2nd batch of
Jupiters (asics anyway) were different ..you could not use them on the earlier Oct units..thus would it have to be a Neptune Board to test this stuff...would a NOV Jupiter
batch board work ...WOULD 0ct 2013 Jupiter/Saturn/Mercury Boards work (even thou some of those are only 4 ports)

So I guess you'd kinda have to check it with a Neptune Board first imho on such a Titan cube experiment....and if brave work backwards to a Jupiter NOV 2013 board and backwards that way to be safe I'd ASSUME if they worked on the Neptune Board with a Titan Cube  they would work for all with the bridge adapter ..but how I'd approach this.

(so much fun I could have 'frying stuff' in the interests of this thread..if I could ONLY win the frigging lottery..the stuff I could 'destroy for Science!" sigh)

Oh ok. Quick summary (I have all of this in my other thread, I really don't want to screw this one up with endless tech prattle)

On a "bad" board:
root@Neptune:/etc/init.d# io-pwr init
TPS65217 OK. Modification A, revision 1.2
Wrong SEQ4 value 0x40
Wrong ENABLE value 0x09
Wrong SEQ4 value 0x40
Wrong SEQ4 value 0x40
Wrong SEQ4 value 0x40
DC/DC converter configuration failed!

On a board where I pulled the shorted cap
root@Neptune:/etc/init.d# io-pwr init
TPS65217 OK. Modification A, revision 1.1
root@Neptune:/etc/init.d#

io-pwr is the command to fire up the DC-DC converter. It puts out three voltages. If a cap is shorted it detects the crowbar and fails.

Well, Im confused ... all that command states is the board powered up fine. LOL! So Im still not sure how that indicates failure.

Well, before the chip would never fully power up, it always gave those stupid errors. Now it comes up clean and oddly enough the red LED is lit on the board (it never did that before). Given that pulling the cap cleared the short, I can say as a flat fact that the cap shorted.

Likewise the similar short on the other board makes me think this is not uncommon.

As to what it says, it might say that either:

a) The FPGA runs super hot and fries the caps (I doubt this a lot)
b) The caps are lousy quality and suck Goat Cock (given the # of blown caps I have seen on the hashing boards I wonder).

Will have to work on it a bit more to verify, but more busted boards would help.

Edit: After pulling the trim caps on the other board, the chip seems to be up: Advanced tab now works. I think I have a cross-verify. We'll see.

What does that say about failure?

Yep, I figured out why the Neptune (and possibly other) boards have been failing.

root@Neptune:/etc/init.d# io-pwr init
TPS65217 OK. Modification A, revision 1.1
root@Neptune:/etc/init.d#

Yaay! Happy me.
