Powered usb hub for bitcoin mining
I was thinking that too. A couple is precisely two. A few is more than two, and somewhere under five? But I think three is the number you should account to. Four is a bit much. I stopped mining a few years ago,. I wish i had heard about Bitcoins earlier than I did. I was too late to the party for the 10, BTC pizzas. Did you read my website at all? I detailed everything you needed know about the workings of the board.
As with much of the bitcoin mining news, they assume that you already own and use a RasPi. The other part of the battle is wattage, which the RasPi addresses.
Its just running arbitrary calculations for no benefit. While I can see some academic interest in the very best, most optimized, way to do those calculations…. It would be extremely wasteful for the bitcoin network to do anything else than what it is already doing.
The mining process not only spends time unlocking coins from the block-chain, they also facilitate the transactions and add more encryption to the block-chain. If they were also curing cancer at the same time or folding protein chains, it would actually be more wasteful than the service they are providing by making this extremely convenient monetary system possible.
The decision to artificially introduce the difficulty factor was made by the inventors of Bitcoin and is purely based on economic considerations, i. There is no cryptographic necessity for that. Sounds like a 5-year old said that. You can see more details at http: Possibly, but this is designed more for Klondike miners or anything else where high current is desired. Thanks for checking it out! Mostly come together and gear should arrive soon. Might have some new projects soon though….
There are quite a few different enclosure available for the Pi but the Adafruit Pi Box is a good fit for this project since the top portion of the case can be removed providing easy access to the GPIO pins on the Pi. Adding the LCD to this project is optional but besides being very cool it gives you an easy way to check on the status of the ASIC miners.
Adafruit provides some python code that displays several screens of information on the LCD such as hash rate, errors, current Bitcoin prices, and network difficulty. So if you plan to run these miners without a monitor connected to the Pi then the LCD makes perfect sense. I also enjoy soldering electronics so the fact that the LCD comes as a kit adds to the general fun level of the project for me. I ordered the RGP Positive kit which has a muli-colored backlight 7 different colors.
The picture below shows what the entire board looks like after assembly. The soldering difficulty level was pretty easy, the entire board took less than 30 minutes to build. Listing the number of devices and the hardware error rate.
The cgminer monitoring script seems to occasionally crash which results in the LCD locking up. The monitoring script runs as a separate process so it does not stop cgminer from running when it dies. Aside from debugging the python script a simple solution would be to setup a cron job to periodically restart the script.
Are you using the Pi to control your Bitcoin mining system? If so do you have any tips to share? Leave a comment below to assist other miners. So Far my rig has been working well, no issues to report yet.
I have a question: You mention a maximum of 48 ASICs. I seem to be able to run a maximum of 18 ASICs using three hubs. I should also mention that the hubs are not daisy chained although I have tried that — they are plugged into separate ports on a 7 port Manhattan USB 2. I would be interested in your thoughts, if you have any on the subject. Thank you for your time and keep up the good work. The difficulty has been rapidly increasing over the last several months http: Overall this rig has been very stable and is still generating some small ammounts of BTC.
Luckily I was able to get some of these USB Block Erupters early enough to earn some return before the difficulty rose too high. As it stands today I would not recommend buying these Block Erupters since you will not be able to recover your investment. In fact they are being discontinued in anticipation of a newer model being released.
This Raspberry Pi setup will work with any USB miner supported by cgminer so if a newer model comes out that looks profitable you can still apply the same concept.
I recommend running the numbers through the Gensis Block Mining calculator http: I love your design and i plan to try it out for my self. But i was wondering, is the lcd display and the extra components needed? The LCD display is completely optional, you can still do everything with out it. You can monitor the miner using a connected monitor, or run it headless once you have everything configured.
This stuff is really interesting, but most miners wont disclose whether or not their rig is profitable, how much does this rig make or lose? My wireless network has a password, how can I make the Edimax Nano Wireless Adapter can access the network with the same password?
