Lottery mining is fun! Product Links (some are affiliate links) - Raspberry Pi 5 👉 https://amzn.to/47StG87 - USB Bitcoin Miner 👉 https://amzn.to/3Sjmdtf In this video I mined Bitcoin for 24 Hours with an Ant Miner USB Stick. #raspberrypi #crypto #bitcoin Antminer U2 V1.2 ASIC Bitcoins Hash BM1380 A brief introduction to a test conducted on USB device Antminer V1.2 based on the ASIC BM1380 with the tool cgminer 4.4.0 with calculations around 1.5 GigaHash/sec. Antminer, bitcoins, BM1380, mining, wallet In June 2014, I so tested the Antminer U2 USB interconnected to a Windows 7 laptop for testing purpose and paid it US $16.00. This ASIC is provided by Bitmain Technologies Limited https://www.bitmaintech.com but I got mine from http://www.aliexpress.com. The goal for me was definitely not to gain any money but just become familiar with the bitcoins vocabulary and techniques. The Antminer U2 from Bitmain works on SHA256 cryptocoins with up to a theoric 2GH/S speed and is based on ASIC BM1380. 1 2. Antminer U2 test steps 1. Review startbitcoin.com 2 1. http://buy-antminer.com/guide/datasheet/ BM1380_Datasheet_v1.0.pdf 2. http://www.startbitcoin.com 2. Get your Bitcoin wallet https://bitcoin. org/en/download, this is a wallet.dat file. 3. Get Bitcoin Core https://bitcoin.org/ en/download, at the time of the test I used a Version 0.9.2.1. When installed the process is bitcoin-qt.exe. At startup the tool is indicating that it is loading the blocks index. A debug.log is created, main subdirectories created are database, chainstate and blocks. 4. Become member of a pool like http:// mining.bitcoin.cz. 5. Get BFgminer http://bfgminer.org, at the time of this test I used a version 4.4.0- win64. 6. Run the Bitcoin Core tool until having a block (can take days...). 7. Install a generic USB driver http://zadig. akeo.ie/, at the time of this test I used Zadig v2.1.0. The device was detected as Preprint submitted to franckjeannot.com 17 juin 2017 "CP2102 USB to UART Bridge Controller in my case. 8. Plug the USB device, if OK the Red LED should be on. 9. Run Bfgminer, provide the url which is with bitcoin.cz : startum.bitcoin.cz :3333 and the login/password. According to wikipedia, 3 Satoshi Nakamoto is a person or group of people who created the Bitcoin protocol. 4. Antminer U2 Specifications — Power : 1.2-2 Watts — USB version : 3.0 — Detailed model : ASIC Bitcoins U2 V1.2 Hash : BM 1380 U020114E2 4.1. ASIC Control Unit schema part Control board PCB was provided as "opensource" with PCB schema 4 . I reproduce herebelow only the schema around the ASIC BM1380 aka U2. 3. http://en.wikipedia.org/wiki/Satoshi_ Nakamoto 4. Orignal schema from Bitmain Technologies : ANT_Miner_CtrlUnit_V1.2.pdf 5. cgminer Output example from cgminer version 3.12.3 Network diff set to 2.62 G Output example from cgminer version 4.4 : Based on the dashboard from https://mining. bitcoin.cz/accounts/profile/ my Total Reward was 0.00012062 BTC... I found this pragmatic approach very useful to have a better understanding of the cryptocurrencies world. Bitmain Antminer U2 V1.2 SHA-256 Bitcoin Miner
