I saw these massive on ebay and couldn't resist. I paid $70 per card. The shipping was rediculous but I was able to get all the card running and bios modded. I could push probably to 33 mh/s but I like stable systems. I'm running in these in HiveOS and getting around 75W-80W per card.

This the best 4 jaw retriever tool I've ever seen. anodized aluminum and magnetic tip. The sleeve is even coated in non stick film. I used these tools all the time to retrieve hidden wires in walls.

My USA made craftsman dremel tool finally died. I've had this for over 25 years. Normally I would suspect a bad switch or brush. After closer look I noticed one side of my motor winding was open. I was able to pull the wire back up and solder it back to the connector. Back in business.

This is a pretty cool new feature on some miners. You can statically lock the GPU core clock reducing power. I personally save 24 watts of power on a 1660 super and 3070. If you have a dedicated computer to mine then you need to be running HiveOS. Windows mining is garbage.
Nice 3070 Video Card

One of the first things that bothered me about these large printers coming out are the external control boxes. I had the box fall off my desk and rip the heated bed connector off. I want to be able to lift and move my printer as one piece. Its also easier to service the individual components now. Now the power supply and dual mosfet and control boards are separated. I never like having the power supply and board sharing the same cooling fan.

The fuse design in BigTreeTech SKR boards is weak. They now use a 1808 fuse that seems to be a little less resilient. If your having a similar issue you can use my technique of tracing it back the source. Its not always easy like replacing a fuse.
