Looks great, I am sure there would be many of us looking to purchase something like this. I am also waiting to get a GekkoScience hub and check everyday to see if I can purchase one.
thanks guyslike sidehack say, my design is working good but this power stage with linear regulator generate warm and need to be cool so this is a working solution but not the best
Linear regulators for high power are gonna cause you some problems. If you're sinking 12V down to 5V, your TO220 are gonna be putting out 40% more heat than the sticks will.
can you help me to find a better solution for this step down 12V to 5VQuote
Our original idea for the Gekko hub was to put in per-port power monitoring. I still think it's a cool idea, so nice work there.
Thanksmany of us use this usb stick power meter to determine power drow by the usb miner, with this indication directly display I think it is a good help to correctly configure USB hub and tweak 5V with screw to have for example 5,2V for overclock for example

As for hub stock, we got hit by parts price increases pretty severely so had to take the thing back to almost zero to redesign for parts we could source affordably. Couple that with a fairly time-inefficient case manufacture process and limited time available for dealing with issues around CompacF manufacture and you see the problem. Good news is we're solving problems and improving our tooling and shipping hubs. And also shipping sticks faster now too. 2022 is shaping up to be a pretty good year for GekkoScience products.
Nice news, if you need help for anything like test or other I'm hereHi all,
with the difficulty to buy a good usb mining hub , I finally worked on my own design
https://i.ibb.co/Nj56pdq/usb-mining-hub.png
main features :
pci-e power connector 12V
3 power linear regulator 5A each
3 variable resistor to adjust 5V output
Atmega328 with LCD to display data like power of each usb port like usb key power meter
4 ports USB and 2 with just power for raspberry or fan
ports 1 and 2 share same 5V with usb hub data
port 3 share same 5V with one usb hub data and port4 with just power (fan, raspberry)
same configuration for port 5 and 6
I plan to add connector for fan because a thermal dissipator is need for the 3 linear regulator and a sensor to manage temperature
It works since one week without any issue

Now I need program ATMega to display data and my prototype will be finish

Hi all,
I have a problem with bitshopper.de, they don't answer to me since december when I order a CompacF
I have never receive my usb miner and they just say wait but ...
so did someone have an other solution to contact then than email ?
thanks

It is a german company, with an imprint:
Ernst Heller
bitshopper.de
Bernhard-Plettner-Ring 38
91052 Erlangen
Deutschland
Tel.: +49 179/ 9754353
The phone number is a mobile number, so it will cost you a fortune, if you are outside the eu.
after discussion with bitshopper, they proceed to a resend.
Thanks to them
