On May 4th, 2013, a user named friedcat from ASICMiner released the first ever bitcoin mining ASIC USB device on the bitcointalk forums, the Block Erupter USB. These came in 7 different variations: - Black (COMMON) - Blue (COMMON) - Red (COMMON) - Silver (COMMON) - Gold (SEMI-RARE) - Blue with surface concentric circle effect (SEMI-RARE) - Red with surface concentric circle effect (SEMI-RARE) While they were the same hash rate, they did have a few minor hardware improvements. I can also supply the print-ready digital versions of these print outs with bleed and crop marks if you contact me through bitcointalk or Twitter.īatch 1 - Block Erupters USBs were all flat colors: - Silver with an orange bitcoin logo (First ones to be shipped out) (RARE!) - Black (COMMON) - Yellowish-Orange (RARE!) - Red (COMMON)īatch 2 - Block Erupter USBs had regulatory markings on the aluminum heat sinks and had sightly better surface processing done on them. First and second batch release print outs of the USB Block Erupter on the Bitcointalk forum, and 1 print out of an infographic by (defunct) showing the Block Erupter components and re-sale price of 1.05 BTC. 1 x 18'x24' shadow box frame - 3 x print outs. This completed set includes: - 12 x ASICMiner Block Erupter USBs (11 unique variants/colors, and 1 extra black (batch 1) Block Erupter) - 2 x 49 Port ASICMiner Block Erupter USB Hubs (First and second releases). The Block Erupter hubs use a 5V rail to power all of the USB ports. They are all fully functional and each mine at ~330 MH/s.īoth of the 49 Port ASICMiner Block Erupter USB Hubs have also been tested using an APX PSU with a 24 pin power connector and high Amp (30Amp required) 5V output. I’m also including another black (batch 1) that is used to display the rear PCB board and hardware components as a compliment the info graphic advertisement in the shadow box frame.Įvery USB Block Erupter has been tested using cgminer.

This collection includes all 4 unique colors from the first Sapphire batch release, and all 7 unique colors from the second Sapphire batch release for a total of 11 unique Block Erupters. To the best of my knowledge, this is the only existing complete collection of ASICMiner Sapphire Block Erupter USBs that has ever been shared online.
