ASICMiner Block Erupter USB Sapphire Complete Collection

Selling my completed ASICMiner Block Erupter Sapphire USB collection set.

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. 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. 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.

Every USB Block Erupter has been tested using cgminer. They are all fully functional and each mine at ~330 MH/s.

Both 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. The Block Erupter hubs use a 5V rail to power all of the USB ports.

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).
- 1 x 18"x24" shadow box frame
- 3 x print outs. 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) bitcoinexaminer.org showing the Block Erupter components and re-sale price of 1.05 BTC.

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.

Batch 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)

Batch 2 - Block Erupter USBs had regulatory markings on the aluminum heat sinks and had sightly better surface processing done on them. While they were the same hash rate, they did have a few minor hardware improvements. 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)

The History:

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.

The Block Erupter USB wasn’t the first ASIC miner released, but it was the first ever to use the USB form factor, and used the first ever ASIC chip ever manufactured. The release of the Block Erupter USB comes only a few months after Avalon released the first ever bitcoin ASIC miner to the public in January 2013, and it comes 7 months before Bitmain unveiled it’s first ASIC Miner; the Antminer S1.

These Block Erupter USB devices have a hash rate of 333 MH/s (0.000333 TH/s) and were available for purchase at a price of 1.99 BTC per USB miner upon release. Market value for 1.99 BTC was around $200-$225 USD at the time. Some buyers who purchased early were actually able to make a bit of profit out of them. These are massively inadequate in terms of mining power by today's metrics. Today, the Block Erupter USBs are technically the least powerful bitcoin ASIC mining devices in the world, since they were the first ever ASIC chips ever created (130nm BE100).
