Hacking KNC Titan / Jupiter / Neptune miners back to life. Why not?

[lightfoot]

Ok, I read in an earlier post on soldering tips on how to add extra data port connectors to my Jupiter controller board.......


My little 25 watt iron is not even coming close to melting this stuff out of the through holes.

What is this stuff?   LOL

ROHS solder. You will destroy the board if you keep that up. Do you know how to use desoldering braid, check out chip-quik to bring the solder down to a lower melting point for removal.

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.

tons of sites do it, try http://www.filedropper.com

I think the dropbox people do it. Try this link:

I ended up using a 35 watt iron and a vacume bulb.

And it worked!! YAY

EDIT: I just watched a video showing chip-quik.......defiantly on my to order next list.

Well done! Use care though, the higher the wattage on the iron the more likely you will lift a trace and make a mess. The controller boards are not too thick, but with the actual miners the problem is the ground planes *are* thick and conduct heat away.

If you really want to do this kind of stuff more invest in a pre-heater for the board. With the board warmed up to 120c, using a small iron is possible when de-soldering without damaging the board.

Keep mining :-)

I just picked up a KNC Neptune set to play with.
The controller board does not have a display for the IP.
Is it a necessary part? If yes, Would you have a replacement I can buy.

Also, Does the GenTarkin upgrade work for Neptunes?

Finally, there is no power cord for the Controller board.
What is the cord I need for that?

Thanks for any advice and help.

No, the display isn't really worth it. Nice to figure out the IP addy but just check your dhcp logs

No, Tarkin fiddled with the Neppies but they went non-profitable too quickly

Normal HDD power cable, 4 pin molex.

Fire up the controller first, upgrade to 1.06 software, then make sure the green light comes on. Then go from there remember to never plug or unplug a cube from the controller with power on.

Thank you for the quick informative responses.
Best place to download the 1.06 upgrade?

I never touched any KNC device firmware other than Titan. Never had a neptune or any KNC sha miner =)

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.

[lightfoot]

Well yes, it did stack zeros at the end so you can do that. Still finding an <32gb micro SD card is getting a bit tough. How's it working for you?

Naah. The BBB is faster than the Pi anyway, so it's going to be quick no matter what. Also you could flash it to bbb firmware, I haven't tried that yet but my image should fit in the BBB on board memory.

Yeah it is getting tough haha. I still have tons of the 8-16gb ones from all these pi. It worked fantastic man. a real turn key operation infact. The bbb is far superior to the pi in terms of speed, you're so right.

I mined for you briefly then had issues with psu cables. I've got some Y cables on order now so i can use some smaller psu with smaller wires here. It just never ends!

Don't wory though mate, ill be mining for you one day. I appreciate the work.

[Instamined]

Is it possible to mine x11 on KNC titans or did that never materialize?

No clue, but now that we have a scrypt based bfgminer running on the bbb that you can compile, it might work. Give it a try.
