Topic: Kickstarter to set world record for Raspberry Pi Mining (closed) - page 2. (Read 3339 times)

Those hubs will work fine with adequate power, I've been using all 7 ports without issue.

They do have a known restriction on the pi, you can only stack 1 hub underneath another.  So 1 hub connected to each port, then stack another hub to each of the available 14 ports, for a total of 98 ports.

BTW, if anyone knows a way around this without modifying the stock Pi, let me know.

If you are thinking of using those D-LINK 7 port hubs, then only 5 of the ports are suitable for USB miners.

I don't know if the Raspberry Pi has a similar restriction, but with with some machines running Windows, you can only chain 4 or 5 USB hubs together. I imagine it is dependent on the chipset used.

I ran 37 USB devices from a raspberry pi for a while. CPU can get swamped if you're not careful going much beyond that. The newer antminers are much faster per device so you can probably get a lot more hashrate without clogging up the pipes.

30 AMUs
5 BPM Blue Furys
1 BFL Little Single
1 BFL Jalapeno

Total of 62 GH/s

I'm going to try to setup a kickstarter campaign to set a world record on a Raspberry Pi for mining bitcoin.  Right now I estimate I can get 174 GH/s out of one Pi.  I plan on accomplishing this via the following plan:

Project is closed, please see last post for final update.

Equipment List:

• 1x Raspberry Pi (512 MB RAM)
• 1 x LCD shield for GH/s readout
• 16 x 7 Port USB hubs with an external power supply
• 98 x AntMiners
• 1 x Kill-a-watt meter for power usage readings
• Live stream for proof of world record being set

Conditions:

• All mining must be controlled by one (1) Raspberry Pi (512 MB model)
• Mining must occur for a continuous 168 hours (1 week) without interruption
• Mining must occur during a livestream for 168 hours (1 week) hours as proof

So?  Why are you here?
I'm bothering posting this because of some of the stigma the Raspberry Pi has gotten when it comes to running these USB miners.  With my extended background in electronics, computers, programming, and linux, I've been able to run my personal Raspberry Pi (the 256 MB model no less) at 9 GH/s for weeks on end with no issue (with two 7 ports hubs and 14 devices).  It's aggravating when I see someone setup 40+ watts of equipment without adequate power and then blame the hub or blame the pi, then they write them off and then just say, "You need a desktop/laptop".

So, I'm here to dispel those myths, actually... I'm going to outright try to destroy them by making just one Raspberry Pi rival full fledged ASIC boxes by pushing it to at least 174 GH/s and beyond.

Still have no idea why your here...
Fair enough, I'm posting this for a few reasons:

1)  To make people aware of the project who may have dismissed the Pi in the past to possibly reconsider it as an option in the future
2)  To get backers, so far the equipment needed is going to need about $4,500
3)  To get suggestions for rewards for potential backers
4)  To tap into a pool of experts who may have technical knowledge of the project who may be able to help beyond my skill set or workload

Wait, you could just keep the money/rig for yourself
My interest here lies mostly with the reputation of the Pi more than anything.  When the equipment is properly powered and supported, I believe about anything is possible.  Yes, the rig will be at my house, but will be property of the world record project.  Any mining done after any potential rewards given out will be done in a wallet specifically for this project.

Still, whats keeping you from scamming?
I'm open for suggestions on this one, I plan on livestreaming quite a bit, but it's still not enough proof for my tastes.

I'm not interested in funding
That's not a problem, if your interested in the project, any technical pointers you may be able to give, or just general interest in the project will be enough.

I'm not interested in any of this
Ummm.... then why did you read all of this?

Ok, say you set the record, then what about the equipment/mining after it's all done?
As I said earlier, a specific wallet will be setup just for the record setting and any mining after backer rewards have been met.  I plan on continuing to break records, by using bigger/better miners and larger compatible USB hubs, using any bitcoin or monies obtained to fund the next record break.  My next goal will be to locate a larger compatible hub and push the pi to the 300+ GH/s and beyond.  Any old equipment will be sold to fund the next step before asking for anymore backing.

Ok, I'm interested, how can I help
Right now, I'm:

• Finalizing an equipment list
• Halfway through doing a small scale test with personal equipment
• Starting on a reward list for backers
• Deciding if there's enough interest in the project to continue

And that's about it.  Anything you could contribute would be helpful, whether it be updates to suggested equipment, code changes on the Pi, or just expression of general interest.

You fool!  9 GH/s is a far cry from 174!!
This was before I really started to consider this project, I currently have 11 more AntMiners being shipped as I type to begin final small scale tests.  If all goes well, I'll be hashing at the rate of 25+ GH/s on a Pi with only two 7 port hubs.  *UPDATE*  Both the power supplies and the miners will be here today, I'll begin testing this evening.  Testing began!

Where is the kickstarter link?
There is none for right now, just asking for suggestions.  When things become solidified enough that I'm ready to start pushing, I'll start the project.
