A Steam Machine Clone For An Indeterminate but Possibly Low Cost
For various reasons, crypto mining has fallen to the wayside in recent years. Partially because it was never useful other than as a speculative investment and partially because other speculative investments have been more popular lately, there are all kinds of old mining hardware available at bargain prices. One of those is the Asrock AMD BC250, which is essentially a cut down Playstation 5 but which has almost everything built into it that a gaming PC would need to run Steam, and [ETA PRIME] shows us how to get this system set up.
The first steps are to provide the computer with power, an SSD, and a fan for cooling. It’s meant to be in a server rack so this part at least is pretty straightforward. After getting it powered up there are a few changes to make in the BIOS, mostly related to memory management. [ETA PRIME] is uzing Bazzite as an operating system which helps to get games up and running easily. It plays modern games and even AAA titles at respectable resolutions and framerates almost out-of-the-box, which perhaps shouldn’t be surprising since this APU has a six-core Zen 2 processor with a fairly powerful RDNA2 graphics card, all on one board.
It’s worth noting that this build is a few weeks old now, and the video has gotten popular enough that the BC250 cards that [ETA PRIME] was able to find for $100 are reported to be much more expensive now. Still, though, even at double or triple the price this might still be an attractive price point for a self-contained, fun, small computer that lets you game relatively easily and resembles the Steam Machine in concept. There are plenty of other builds based on old mining hardware as well, so don’t limit yourself to this one popular piece of hardware. This old mining rig, for example, made an excellent media server.

Qron0b: a Minimalist, Low-Power BCD Wristwatch
Over the decades we have seen many DIY clocks and wrist watches presented, but few are as likely to get you either drawing in the crowds, or quietly snickered at behind your back, as a binary watch of some description does. A wrist watch like [qewer]’s qron0b project which also uses BCD encoding to display the current time is among our more rare project types here, with us having to go all the way back to 2018 for a similar project as well as a BCD desk clock.
As is typical, a single CR2032 coin cell powers the entire PCB, with an ATtiny24A or compatible as the MCU, a DS1302 RTC and the requisite 4×4 LED matrix to display the hours and minutes. Technically three LEDs are unneeded here, but it looks nicely symmetrical this way, and the extra LEDs can be used for other tasks as the firmware is expanded from the current setting and reading of the time.
The AVR C firmware can be found in the above linked GitHub repository, along with the KiCad PCB project and FreeCAD design files for the watch body. The body accepts a 22 mm GT2/GT3-style watch strap to complete the assembly. With a single CR2032 you’re assured of at least a few months of runtime.

Adding Solar Power to an Electric Tractor
In my country, we have a saying: the sun is a deadly lazer. Well, it’s not so much a folk saying as a meme, and not so much in one country as “the internet”. In any case, [LiamTronix] was feeling those cancer rays this harvest season when running his electric tractor, and realized that– since he’s already charging it with ground-mounted solar panels anyway–if he’s going to build a roof for his ride, he might as well make charge the batteries.
Another bonus is safety: the old Massey-Ferguson at the heart of the electric tractor build didn’t come with any rollover protection from the factory back in the 1960s. Since having however many tons of tractor roll onto you was bad enough before it got a big hefty battery pack, we heartily approve of including a roll cage in this build. Speaking of battery packs, he’s taking this chance to upgrade to a larger LiFePo pack from the LiIon pack he installed when we first featured this conversion in 2024.
Atop the new roll cage, and above the new battery, [Liam] installed four second-hand 225 W solar panels. Since that’s under 1kW even if the panels have not degraded, the tractor isn’t going to be getting much charge as it runs. In the northern winter, [Liam] is only able to pull 80 W from the set. That’s not getting much work done, but who wants a tractor without a cab or heater when it’s below freezing? In the summer it’s a much better story, and [Liam] estimates that the roof-mounted panels should provide all of the energy needed to run the tractor for the couple hours a day he expects to use it.
If you’re wondering how practical all this is, yes, it can farm — we covered [Liam] putting the project through its paces in early 2025.
