A few weeks ago, I posted photos and a parts list for a simplified 4-bord DIY Skyminer for noobs. That post can be found here.

Since that time, I ordered a few additional parts and here are some photos and a parts list for an 8 board Skyminer that uses a USB charging hub for power so that you can still avoid wiring a PSU brick if that's not something you are comfortable doing. Here are the parts that were used:


Orange PI Prime Boards

I purchased Orange Pi Prime boards. Many DIY builds in the community are using different boards now since the Prime boards are hard to find at a reasonable price. One benefit to using these boards is that this setup will most closely match the official miners and the official Skywire Linux images for these boards are available on GitHub.

Xentris Wireless 120W 10-Port Smart Charging Hub

This USB charging hub is the one I chose because I liked the design and it has sufficient power to run 8 boards. You would need one that is at least 100W for 8 boards, and make sure each port is 2.4A.

5V USB to DC 4.0mm x 1.7mm Power Cables

These power cables are sufficient for the power to run the Orange PIs. You could also order them from Ebay for cheaper although the shipping would likely be slower.

Micro SD Cards

You will want to use fast Class 10 Micro SD cards. 16 GB is what the official miners come with.

40x M3 30mm Standoff Spacers

40 spacers is the exact amount of spacers I used in this setup.

TP-Link TL-WR1043N Gigabit Router

I purchased this gigabit router and it was pretty easy to flash OpenWRT onto it. I ended up purchasing it from NewEgg. Originally I ordered the product off of Amazon, but the version that they shipped me was actually the older version WR1043ND. That version is also OpenWRT compatible, but I was looking for the newer and faster version of the router so I reordered from NewEgg.


Switch

This cheap switch can handle up to 7 devices, not including the incoming connection from the router. Due to this, 7 boards are plugged into the switch and 1 of the boards is plugged into the router itself. An alternative method would be to get an 8+1 port switch like the one referenced in other parts lists.

LAN Cables

You can use any short Cat 6 Ethernet cables. I used these from the parts list that has floated around and got some in both 15cm and 25cm lengths. You will need at least 9 (8 for the miners and one from the router to the switch).

Summary

Those are the parts that I used to build the miner in the photos. The only part not mentioned is the plastic top and base for the miner rig--I just used plexiglas that I had around the home for that portion. Hopefully this guide provides some additional insights on ways to set up a miner for anyone who doesn't want to manually wire the PSU brick!
