USB miners and the Dipo Electronic 19 port 20A USB Hub

20 Nov

This is a 19 port hub with an integral power supply that is capable of reliably supplying MORE than 700mA per port without overheating or becoming a fire hazard.

Dipo  hub , with engineering modifications for reliability

Dipo hub , with engineering modifications for reliability

Some of the Basic specifications:

– Fully 480mb/s at each port
– 16 Front facing Standard A USB ports
– 3 Side facing Standard A
– 1 Master hub connection Standard B for connection to Computing Equipment or other hubs
– Fully fused internally via multiple poly-fuse resettable fuses both on each individual port and on the main power feed to the Ports.
– UK/European standard 3 pin power plug
– Hub runs COOL

Unlike cheaper USB ports that only implement links at USB 1.0 standard (12mb/s speeds but state they are ‘compatible’ with USB 2.0) this is a professional FULL 480 Mb/s port that complies and implements the full 2.0 USB standard. It may also be used to connect to generic USB 1.0 equipment.

The good thing about these hubs is that you can load them up with 19 Bi-Fury miners (around 76 gh/s) and the miners would STILL run as intended.

The supplier is a Chinese company we have been working with, each hub we sell is inspected both at the electrical and electronic levels to ensure the correct functionality of the product.

Why Apple’s OS X really annoys me

17 May

One of the most annoying things about OS X, is its continual insistence of leaving ‘rat droppings’ all over my drives.(Apple they are MINE not yours)
Yes, I’m talking about the ‘.DS_store’, ‘.Spotlight-V100’, ‘.Trashes’,’._.Trashes’, ‘.fseventsd’ and christ knows what other crap Apple insists in writing to my drives.

I am well aware the role such files play, but they also play havoc with development for embedded devices.

10.1″ Utopia, USB & flexible cable issue

15 May

Well, It has taken some time to get the issues related to the USB port fixed, it seems it was a dual issue of broken USB socket AND a flakey inter board connector, if you remember back to the A8, this was also an issue.

See here for more details:

If you are interested in supporting a good cause for a public domain CPU design, then pop over to OpenCores and make a small donation (Say a Dollar)

It is for a good cause.

 

10.1″ Utopian wet Dream

06 May

Ok so we have the  brand new Utopia G10 from Hiapad
We had actually started to take a look at the device, but we seem to have a couple of issues related to the USB & HDMI connections.

We also have photos of partial disassembly, that was until we dropped the digital camera.
Luckily, we have been able to recover a couple of the photos, unfortunately it is going to require a new photo session to get a clear breakdown of the full device.
