Um if you mean by idling dies when the dies drop off and no longer mine? Thats exactly what my firmware "bandaids"
My firmware shuts off the cube w/ dies that have gone missing and then powers it back up. Restarts mining as needed.

Its not going to be an exact factory image exactly like theirs because I believe theirs run some setup scripts n stuff on first boot. Mine will be the modified & working version of theirs. Passwords will be default, u just have to set up the pools via webgui.

Ur paying .5 btc for an img file? shoot....
Ill make one for you of my current build. It will need to be at leas 8GB size card tho.

yall dont know how to ssh into the pi and update a few files? its not really that hard... =/

um....

Hi all, I recently purchased a Titan from a friend.

It had dies dropping every few hours or so, was highly annoying. Had to power cycle the entire miner every time. I suspected there was a way to issue a power cycle to the cube DC/DC's directly. After SSH'n into the pi turns out KNC had scripts that did just that, but they werent ever being utilizied.
They coded one DC/DC monitor script(watchdog script) for die monitoring while mining. The problem is it was only issuing soft resets to the offending dies, it was not attempting to power off the affected cube and power it up again then restart mining.

Ive basically modified the watchdog script to: STOP bfgminer, POWER CYCLE the cube which has dies offline, START bfgminer.
I have confirmed the script mods working 2x now, Ive confirmed the POWER CYCLING via script running manually more than 10x and each time the dies came back.

NOTE: this fix will work for dies that go offline which are fixable by a power cycle. It will not work for otherwise permanently damaged dies.

Ive also modified the webgui to show more stats in status page:


Link to my Git:
https://github.com/GenTarkin/Titan

You should just be able to SSH into ur pi, download my git in a new dir then copy the contents of that dir to /home/pi (overwriting the dirs/files in that director, which has all the miner binaries & scripts)

I can confirm now that the monitor script works, so the code I posted above works. I just had a die drop(had to wait 12hrs for it to happen) and the monitor (watchdog script I modified) detected within 30 seconds or so, then  stopped bfgminer, power cycled the cube w/ dropped die, started bfgminer. Die is back up and running =)
Why KNC didnt code it this way to begin with is beyond me.

Ive been working on updated watchdog script & webgui stats for titan.
Ive started a new git repo here:

https://github.com/GenTarkin/Titan

I didnt know how to fork knc's original source cuz it has submodules n crap and git is confusing as hell rofl!
So, I made changes locally then created the new repo u see above.
All files are the same except  a couple of the webgui files and the watchdog script. So, it would be safe to rename the original folders and put my new ones in their place.

Anyways, my modifications to watchdog script stops bfgminer, power cycle the cube that has die/dies offline, starts bfgminer.
Its worked 1 out of 1 times so far =P wishing another die would drop so could confirm functionality of script.

Heres what stats look like now:

nope, I believe frequency is hardcoded or something, either way if you could do 350mhz u wouldnt want to due to the shitty power design of these things. 1 PCIe 6 pin connector is barely designed to handle even the 300mhz factory load settings. They should have AT LEAST used PCIe 8 pin connector.

Regarding Titan, would anyone be interested in a software fix which power cycles the cube w/ offending dies and restarts miner software?
Im still testing it out, but I noticed that part of KNC's code doesnt seem to work when rebooting pi, that is it, doesnt tell the dc/dc's to reset for the cubes like its designed to.
Ive implimented the dc/dc power off & power on into their watchdog script that runs while cgminer does and so far, I have it power off / on the cube that it thinks needs its die reset, instead of just issuing a soft reset to the fpga controller it issues a bfgminer stop, offending cube power off / power on, bfgminer start.
In testing, doing this manually works 100% to bring back dies that just drop off for whatever reason but are sill in fact good, they just need a power cycle.
The trick now is just placing it in the right part of the watchdog script(this is the part that is still in testing). But it worked correctly so far 1 out of 1 time since implimentation. =)
If anyone is interested, let me know, Ill post instructions if enough people want it =)

While it may not seem like it, when you think about the practicality of it, it actually is very difficult. If you dont have over a $5000 safe say goodbye to it in any long term fire. You have to trust the software / machine its created on, not only that, but also when you redeem it.
I like the idea of a trezor because while its backed up on a sheet of paper, that piece of paper is backed up by the trezor. Since the piece of paper holds backups to all wallets included any generated by a password .. if the paper gets compromised ... noone would know the passwords behind which ur funds are hidden by. Restore just the seed only and you have a 0 balance wallet restored.
If I had tens of thousands of BTC, Id feel much safe w/ it on a trezor + backup seed on paper(all wallets hidden behind passwords) rather than a single piece of paper holding the fortune and also happens to be a single failure point.
The alternative to a single cold storage piece of paper would be BIP38(I think) encrypting it w/ a decent password and putting multiple copies of that paper everywhere for redundancy.

You cant replicate the convenience of trezor ... what you mentioned, doesnt sound very convenient. Try that in a retail outfit in which u pay for something using BTC. Its impossible the way you mentioned.
Like I stated, trezor offers pretty much near the same security as a cold storage slip of paper ... with the convenience of a wallet on ur phone. I know, Ive used trezor w/ mycelium on my cell phone =)

The whole point is, what if you could have a hot wallet that has the security of a cold storage single priv key?
Thats what trezor offers =)
Trezor allows you to have as many unknown wallets as passwords you can remember in your head. Better yet, a single mnemonic seed backs up all of those wallets. That seed would be the trezor's "cold storage" =) ... But unlike traditional cold storage, that single seed restores all of ur keys in all the wallets u created w/ trezor. Additionally, because trezor's seed is based on a BIP, its restorable via any wallet that correctly supports that BIP(in the case you dont have another trezor).

Ledger is crap, I have the open source version of it: HW.1, I wouldnt trust any BTC to the device. Has very little software wallet support(greenaddress) which is a piece of shit. Sure, ledger has their own wallet but its online and closed source last I heard. Also the device firmware itself is closed source. Also, if u forget the PIN just 3 times it wipes itself, thats not cool. Has nowhere near the features of trezor.
Lets just say after testing both trezor & HW.1, I trust the trezor WAAAAAY more.
The multiple wallets(yes multiple wallets, not just addresses) behind as many passwords as you can think of on trezor, all backed up by one seed is what I absolutely love about it.
Trezors way of anti keyboard sniffer hacking the PIN is also ingenious, that security is impossible to do w/ a ledger.

The security is probably close to the same, the advantage w/ the trezor is you can use it as a hot wallet but have the security of a cold wallet. Heck, I use my trezor w/ mycelium on android phone. Theres nothing like being able to spend on the go w/ the security of a cold storage wallet =)

Nope, the trezor is backed up by a single (1 for btc wallets, 1 additional for LTC wallets Im guessing) BIP standard HD mnemonic seed. Write that down on paper and store the way you mentioned. You pretty much have a highly functional cold storage / hot storage setup.
Even if the HD seed is compromised, they would still have to know ur password to the wallets ur actually using =)

Trezor is pretty awesome. Can have any number of wallets hidden behind not only the PIN but also behind passwords. A different password used is a different wallet(collection of addresses) tree. All derived from the same backup seed. Also, from what Ive read, using electrum-ltc you can generate an LTC(seperate seed/wallets w/ passwords) wallet in trezor alongside ur BTC wallet.

one word: pirateat40 =(

Does it take into consideration the LTC reward drop in 40 days?

Yeah, I bought a Titan for $3000 a week ago, and hell at this rate that even seems like a bad fucking deal.
