![]() Now, the first item that you want to pick up is called a Raspberry Pi. I will place some links to all the parts down below so that you can get started on your project. So, here’s all the pieces that you need to start building your own Bitcoin miner. So, give that a watch, get caught up, come back and we’ll get started. So, if you’re unfamiliar with Bitcoin I do have another video that has all the 10 things that you need to know about Bitcoin. What’s going on every one? This is Fred and today we’re going to build a Bitcoin miner. And while even at these quite high operating temperatures the AntMiner U1 does manage to work good and stable enough without active cooling, it is a wise idea to keep the temperatures lower especially on the long run if you plan on mining with these USB BTC ASIC devices for months without problems.Transcript - USB - Bitcoin Mining Setup Guide The thermal image of this side of the USB ASIC shows even higher temperatures – up to 74.8 degrees Celsius maximum measured temperature. The other side of the Bitmain AntMiner U1 is more important as there you will find the actual elements of the device on the PCB, including the Bitmain BM1360 chip that does the actual calculating as well as the power elements that also get hot. On the back of the AntMiner U1 there is an aluminum cooling plate and our thermal images show that in just about 10 minutes of use this cooler gets to a temperature of about 68.8 degrees Celsius and that is actually quite hot. Bitmain recommends that you provide additional cooling for these devices if you plan to overclock them over the stock 1.6 GH/s performance, but we checked how hot these small USB powered BTC ASIC devices can get and their “default” hashrate and our findings confirm that it will be a good idea to think about using a fan to cool them even at 1.6 GH/s. These devices are rated at 1.6 GH/s hasrate with 2W power consumption and you can downclock or overclock them by software as long as you are able to provide sufficient power and cooling. – To download the latest official cgminer 3.12.3 with ASIC only support…ĪntMiner U1 is the smaller USB-based Bitcoin ASIC devices made by Bitmain, they contain just one BTC ASIC mining chip (BM1360) and has been designed to be powered by a USB 2.0 port. Don’t forget to change the pol and worker/password with your own settings! We’ve already measured the operating temperature of the AntMiner U1 at 1.6 GH/s and they do get quite hot even at “stock” frequency. Do have in mind that overclocking the AntMiner U1 should be done only after you add a cooling fan to improve the operating temperature of the device. The above example will run the AntMiner U1 at 200 MHz and should produce a hasrate of about 1.6GH/s, by increasing the frequency number to 250 for example you can get 2 GH/s hashrate and 275 should get you 2.2 GH/s. ![]() So we would advice to download and use the new cgminer 3.12.3 along with your AntMiner U1 devices and below you can find information on how to run it:Ĭgminer.exe -o stratum+tcp://:7777 -u yourworker.1 -p password -icarus-timing=short -anu-freq 200 The support in the new cgminer 3.12.3 offers much easier use and more stable hasrate, the HW error rate also seems a bit lower compared to the results with the older version of cgminer. The latest version of cgminer 3.12.3 has built-in support for the Bitmain AntMiner U1 USB ASIC devices, so there is no need to use the older modified version of cgminer 3.8.5 that Bitmain provides for use with their USB Bitcoin miners.
