#USB BLOCK ERUPTER WINDOWS 7#
Most of them are outdated regarding Windows 7 and CGMiner. Let me first say, I have read every tutorial on "Setting up Block Erupters" I could find. It works fine in another machine and has hashed properly for a few days with no/little hardware errors. I am using a "known good" 333Mh USB Block Erupter. You cant solder big chips like nvida grafik chips or cpus, but you can solder most connectors, bga's inįor bigger chips you need a realy big irda station with pre-heater.This really should be posted to the "Mining Help" board but.I am new so I am forced to post it here. Without demaging your targets, better learn on old motherboards first. Its realy worth and makes the work mutch more easy.īut you need to get a feeling for it (air, temp, time), you need to get some skills to handle it correctly Look for aoya hotairstations, arround 80€, they seems to be realy good for the money. You get it from 50€ to some tausends euros. If you work with elektronics, especialy with smd parts, buy a cheap (not the cheapest) hotairstation. Mostly the volterra vrm's getting demaged over time caused by overclocking and heat.īut for that you need a preheater too, you cant desolder vrm's without a preheater.
I also repaired many ati hd5970 grafikcards with it. I solder with it mostly micro usb connectors of phones, bga's, other connectors, smd parts. i have a better feeling with the hotair station. Sometimes i use irda station too, but i dont like it. I like it more then the expensive jovy system. I have 2 other cheap hotairs from china, this two didnt work good since day 1.īut the first one is doing its job realy good. this cheap hotair works since 7 years pefectly till today. Yes, i have a jovy proffessional hotair station in my work, but i use a cheap 80€ aoia hotairstation from ebay since 7 years.
#USB BLOCK ERUPTER SERIAL#
Will be downloading the referenced serial programming software. WOW! I have experience with soldering but not with such small components. I have to ask what Solder iron do you have? That must of been a tedious task to solder the chip properly to the board. Hats off to you and many congrats on taking this project to the max and reviving your BE's. SO NEVER CONNECT MORE THEN 5 VOLT TO YOUR USB HUB!ĪND DONT CONNECT MORE ERUPTERS TO YOUR HUB AS YOUR PSU CAN SUPPLY! So i soldered all back, and my computer is still detecting it, but without a working asic. we could repair or change every other part, but not the asic itself. So at least i desoldered the BE100 asic chip and TATAAAA! the asic miner is detected again.īut that also means, the WORST CASE for me!Ĭause every part would be changeable. So i started to desolder every part on the usb miner, exept the silabs chip and the asic.īut still, the silabs chip is getting very hot and the computer dont detected it! Into a working usb miner, and it still was working. I desoldered every part and checked it, and all parts seemed to be ok, i even soldered the components from bad usb miner I ordered brand new CP2102 chips and soldered it in, but the only thing that happens was that the silabs chip got very very hot. i had connected a big fan and 4 block erupters, but asap when i connected the jalapeno power supply, I killed 4 block erupters by connecting a jalapeon power supply to my usb hup.
NEVER PRESS "Custom Data Lock" to LOCKED, cause this will permanent LOCK this data and you can never change it back! If you have more, you need to repeat this step with every device, but you need to use different serials! It will write your own new serial into the eeprom and now you can connect 2 usb block erupters without any problem. So now goto "Serial Number" and write your own serial into it: If you whant to solve this problem, then you need to write your own serial into the silabs EEPROM chip.Īt beginning standart config of the usb miner looks like this: Usb miners have same serial, causing a conflict. If you connect your usb miner with 2 different usb ports and asap when you connect the 2nd miner into your usb portĪnd you see in device manager that yellow "!" and you dont get 2 usb miners and no comport, then its because all
