With help of the 3D printer, I've added a 40mm fan to the chipset and a small heatsink to the VRMs

Looks nice! What did you use the 3D printer for exactly?

Thanks, the small black clips that hold the VRM heatsink in place are 3D printed (It's only a regular thermal pad beneath and I wanted it secure). There is also a mounting plate beneath the 40mm fan that clips onto the chipset heatsink. It's all pretty rudimentary but I'm happy with how it turned out.

I wish I'd taken some closer photos before I installed it all, here are the 3d renders:

They're perfectly fine, I saw that the printed parts are what's secured to the board but I couldn't grasp how exactly they hold the heatsink. Thanks, now I get it and it's a very nice and simple idea.

Setup 2 more "lotto miners", this time using the open source NerdMiner V2 software on a couple "cheap yellow display" or "CYD" (ESP32-2432S028) dev boards. I've got 4 of these I picked up on sale over on Amazon for various projects. Two of them I dedicated to messing around with BitMaker's NerdMiner open source ecosystem. Now that I've got them flashed, running, and mining, I just need to give them a proper home. I spent a couple hours last night designing what I hope will be a cool stand for them to sit in. I'll be printing them later today to see if I messed anything up or not.

The device shown in my post a couple pages back is also a CYD dev board, but it's running the proprietary closed source NMMiner software and it's pushing just over 1000 KH/s. I wanted to go open source this time, and the best out there for that is the NerdMiner software, but it's currently limited to about 300-400 KH/s. Though apparently, the BitMaker team has said they are working on getting full use out of the ESP32 to catch up to NMMiner and get up to 1000KH/s. Not that it really matters, these are really just cool fun tech toys, at this low-end solo mining, that 500-600 KH/s difference really doesn't amount to anything. It's just cool to see it run as fast as it can!

I just picked up a USB slitter so I can power both at once off one wall wart.

Never thought I'd have so much fun playing a lottery with a virtually nonexistent chance of actually winning. 🤣

Customized a simple case I found. Stand came out well enough. My "NerdMiners" now have a proper home to play the Bitcoin lottery. 🤣

Just need my Micro USB splitter cable that's arriving tomorrow. 😀

At that low a hash rate you can probably quintuple your odds by putting a hula hoop on your front yard and waiting for a solid palladium asteroid to fall in it.
