Hi, isn't the problem the dirt which resides on the floor? so you clog your miners within a short period of time.

are you talking to me?

I live in a house, there is no dirt on my floors lol.

specially in a house, right. :-)

Oh lord, let's try to stay on topic.

Two problems:
1) That solution will not have enough surface area to keep the main chip cool. The power supplies are the bigger problem, but the best solution is to run them a bit more slowly (60-70mh) and not at a screaming 80. Also someone else made a new bracket for the factory heat sink that allows you to stick heat sinks on the supplies.

2) Ability to dump more heat does not fix the problem that the power plug on the Titans is already over limits. Pull more power and you burn the plug which shorts and destroys the cube in a lot of cases.

I ran a Neptune with liquid cooling, worked great until the pump stopped one night. Small explosion, big mess.

https://preview.ibb.co/dtbQd5/SinkPack.jpg -> The big one is a bracket for the main large sink so that aux sinks can be mounted on the DC/DC's.

Well I know I'm not the first one who is manufacturing a X Bracket, but I'm in Europe and that's new :-) (at least).

Also I agree that the plugs are the weak (PCB I did not X-Ray it for good) component Bottleneck for Power. But I came up with a Double Plug solution on top of each other bridge-soldered together.

As soon as I start manufacturing, please let me know if somebody needs Cube upgrade Kit. (primarily for Europe people, but I will make an exception for all Forum members :-))

BTW: how can I insert pictures directly in the post., I used img tag and it shows as link?

Mr Lightfoot.

The lights, (on the titan board) act as you said, except it does go to green, but only shows spimux, on the display.


I received my jupiter board and it seems to work fine, everything comes up ,but no hashing.
zero hashing, as you talked about earlier.
still can't get to advanced mode, in the knc-firmware either, using knc titan 2.0 (2.02 doesn't work for me).

I had cleaned these several times before without anything happening. Removing the heat sink,  totally cleaing it and replacing it, properly.
These went due to power supply problems.
My big military spec gold-plus...power supply, only lasted less than a year.
I turned it off, and one cube was ok, then back on and cube 2 was not communicating.
It was running flawlessly since I got it, 4 months after it's release.
If I ever unplug anything it is turned off, first.
Same with computers, since 1974.


on to the titan board(s).

I will p.m. you about sending you unit(s).

Oh I just set up a thread on litecointalk.io where I can fix these things.

https://litecointalk.io/t/fixing-and-hacking-knc-titans-because-they-break-from-time-to-time/1708/2

Posting here so people there can come here, see this, and know that thread is mine.

Ok, the lightfoot bb code is ready for posting somewhere. Dropbox seems to want email addresses, they suck. The file is 900mb 7zipped, a image file of a 32gb SD card. So get a 32gb or bigger SD card, tell me where to put this file, and people can use it.

C


will the difference in speeds matter on your choice of a SD brand/card for your BBB black mod above?

I plan on getting a MicroSD Sandisk 32gb Class 10 card but they come in 30/48/68 speeds or some such

not a big diff in price so if the higher speed helps a bit will grab such

just figured I'd clarify the microSD speed on a 32gb Sandisk Class 10 before I picked up a couple to play with the BBB code


No real need to get a bigger sd card like he suggests. Just use what you have and truncate the empty space he has on the .img file before burning it to a sd card.
pm me if you need help with that.
If You could shrink that image and upload for us im sure others like me would be very gratefull, cheers

Well I compressed it with 7zip so it is about as small as it will be. Seriously, I can't find an SD card smaller than 32gb here, if someone wants to send me a 4gb one I'll transcode it.

There is nothing on that empty space. Linux puts pieces everywhere but only on its partitions. Just truncate the empty space using linux or cygwin on windows. A simple install of cygwin will suffice.
Its a simple process that takes no time at all. Remember to put the .img file in the cygwin (what it thinks is) the user folder (home, root, pi) whatever you name it.

@supersonic i'm not comfortable uploading someone else's spaghetti, sorry.
