![]() I also think that this is a very stylish device.īe aware that since this is a USB 3.0 Hub it will not work with the raspberry Pi, this is also the reason why I settles with the D-Link hub. So you can power 9 Erupters and a Fan to cool them down. The last port is just for charging or for a fan which comes in handy. It comes with a 5A power block but only 9 of the 10 ports are full USB ports. ![]() The other device I am keen for is the Anker 10 Port USB Hub. You should be able to power 6 Eruptors but I think its best to power 5 Erupters and an additional USB fan to cool them down since they sit next to each other and will produce quite a lot of heat. I was reading up a lot of reviews and ended up with the D-Link 7 Port USB Hub, it comes with a 3A power block and a lot of people in the mining community seem to use this Hub. With a setup like this you can easily max out the 127 device limit with Hubs having 7 ports each. Hub 4 is the last Hub in the daisy chain, you can not attach more hubs to this one, however you can attach more hubs to Hub 1 to Hub 3. Now you have different possibilities to set the chain up, you could use 4 Hubs and plug each in the Hub before it _ _ _ _ _ Per specification one can attach up to 127 devices to a single USB port. According to the USB specification, the daisy chain can not be more than 5 hubs deep, the first hub being the USB port itself. But be aware that there are limitations with daisy chaining. If you want to do that, keep in mind you will need one extra USB Port. So you would probably not run into any problems when using only mice, keyboards and flash sticks on such a hub.ĭaisy chaining is the process of plugging in one USB hub into another. You may wonder: “Why would they sell them that way than?” – well a current draw of 500mA is the maximum in the USB specification, but not all devices max that out, for example a mouse or keyboard draws far less than the maximum of 500mA. So do not get fooled by USB hubs that come with 10 Ports but a power supply with 3A. You can calculate that quickly: Ampere rating of the power supply So if you get a hub with 10 ports and a power supply with 2.5A you will only be able to use half the ports. ![]() Also you may want to cool your Eruptors at one point, so keep the position of the ports in mind too so you do not have to get a fan for every single Eruptor but can cool down a bunch of them with just one fan. I will go into detail what you have to consider to chose the right USB hub for your needs.īasically the more the better, but keep in mind that there should be enough space between the ports so you can put one Eruptor in each port without having to skip one. But if you do, solo mine and hope for the best.If you are thinking about building an Erupter mining rig there are some things to consider when choosing the USB hubs. Take my advise and don't buy either of these. Thats it - do it yourself if youd like, but be warned that the Erupter isnt especially profitable and has about a 200 day payback period which means in a month or two it wont have a BreakEven point at all due to rapidly increasing difficulty. Unless you solo mine bitcoin and hit a block, you will ALWAYS lose money with these because of the power they use. Its a 60 10 port USB station with (10) Block Erupters which cost around 40-50 each and a cheap fan. Just google what coins use this algorithm. Now moving on to your links, your looking at ETC there. Anyways, they were compatible with Nicehash a year ago the last time i looked into it, can't guarantee for nowadays. They do work just fine, i have a few of the GekkoScience that I bought when he developed them, but that was more to support his work, because he's kinda cool, at least from what i know of him on the forums. So to answer your first question, you can use them to mine any SHA256 coin, not just bitcoin, however you'd be lucky to make pennies. They are grossly obsolete, but if you already have them then well welcome to the party. To start with, if your considering buying either of these to make coin, don't bother.
