Perfect school project thing. Imagine you have an electronics/computer course and present your students with this circuit (without the print mask!). “See? Power supply, power LED, three other LEDs, four DIP switches. Here is the circuit diagram, if you cannot figure it out. Your task: Find out what this thing is and how it works. Bonus: give a meaningful description for the settings of the switches.”
It will run doom before boxing day.
Am I the only one super unimpressed by most “it can run doom” things? It’s either some beefy arm CPU or a total hack where it isn’t really running doom and they shoved a raspberry pi in it or something.
That is because most things can’t run doom without modification. I’m fine with adding stuff but displays and inputs need to be on the hardware and the thing must look like its untampered with. For me it’s just a funny magic trick so I’m not that bothered if it’s faked
Is this what they use to power those cheap android tablets you get from wish?
This seems like a great computer to use in schools to teach how a computer works
Funny it could sell out when it looks like 4 7400 logic chips that could be wired up on a breadboard.
Yeap, that’s all it is plus the PCB and accessories. Looking at it, looks like a 74HC00 - quad NAND gates, 74HC14 - Schmitt trigger inverters, 74HC74 - A dual D flip-flop, and a 74HC153 - dual 4 input mux.
The clock isn’t even a 555, just an RC circuit passed through the Schmitt trigger and the provided hardware XOR is where our NANDs come in.
It’s a neat little project but I think good CPU lessons need to have a MAR/MDR/CIR and show the fetch, decode, and execute cycle. Because a lot of modern concepts derive from asking the question of “how do I optimize that?”

With scalpers being especially prevelant in the tech scene (hello pi), being sold out just doesn’t have the same ring to it anymore you know?
Eh, for the company making them it still has that same old Ca-ching sound
Why do these articles always go on about stuff being sold out like it means something? Even if it’s true, that almost certainly means they’ve simply been bought up by resellers.
I recently needed a plumbing part. Obviously no one’s getting excited about plumbing parts. That was also ‘sold out’ on the manufacturers website.
In reality there are a thousand resellers selling the thing. Manufacturer doesn’t need to have large warehouse or deal with a large number of customers. Resellers get to make a profit by selling for more than the large order unit price they paid. Customers like me get to buy the product at less than the original small order price the manufacturer was asking.
Can’t wait for the Skyrim release
That’s cute. Fun.
To anyone interested in SBCs look for Orange Pi at AliExpress.
