DOOM. Boil it, mash it, stick it in a stew, it’s the game that runs on anything and everything. Now, the classic shooter is running on a rather unlikely target—a cheap clamp meter of very limited resources, thanks to the work of [Artur Bieniek].
The clamp meter in question is the FNIRSI DMC-100, which can be had for the low price of just $30 or so if you know where to look. It’s a far cry from the many thousands of dollars you’d pay for a heavy old 486-based machine back in 1993. [Artur] got the doomgeneric engine running on the Artery AT32F415 chip that runs the clamp meter.
The chip is pretty capable, with its 150 MHz clock speed, though the 32 KB of RAM posed rather a big limitation to the project. It may be one of the lowest RAM DOOM ports out there. Even with this limit, [Artur] was able to get Episode 1 of Freedoom: Phase 1 loaded on to the thing, including E1M1 to E1M9 along with the title screen, intermissions, the finale, the menu, and four save slots. Color graphics are displayed on the meter’s 320 x 240 screen, and there are even sound effects on the built-in buzzer. Controls are mapped to the rather curious choice of a DJI RC-N1 drone controller.
We’ve seen DOOM running on everything from desk phones to completely custom CPUs. These days you have to try pretty hard to find something it hasn’t already been ported to.
Might try on mine
That multimeter does NOT have everything you want in a multimeter. It has a horrible user interface. My Fluke multimeter has a round switch and two buttons, and has a user interface through which I can almost instantly choose the functions I want, without even looking at it. Very important if your holding two test leads on a component with one hand and have one hand left to switch functions without your test leads slipping. :)
A $30 chinesium clamp meter ?
No thank you.
If you need a clamp meter, it’s likely you’re working on high amperage devices.
Where arc flash is a very strong possibility.
I’ll stick to a genuine Fluke.
Nonsense, I needed a clamp meter to check parasitic draw on a car battery so I bought this thing, works great for hobby shit. Yeah I have my fancy meters for work, but honestly I like this one
These things are safe enough if you use them responsibly, and are very capable for the price.
I wouldn’t get one for my nuclear weapon R&D program or something, but I am glad to live in a world where these are available to hobbyists.
There’s also a wee bit of price difference between a fluke clamp and this guy.
Do you understand it’s a clamp meter? Compare apples with apples. My fluke clamp meter is less capable than this one and significantly more expensive.
Hmm, adding a time circuits skin to the DMC clamp meter?
Controlling it through its measurement interface does seem like a missed opportunity ;). Wouldn’t it be cool to use the knobs of a current supply for that, with a wire running through the clamp…
Cool project nonetheless of course!
“DOOM’s been ported to just about every chip out there.”
“How portable is it?”
“If DOOM were any more portable, it would run on a potato chip.”
To be honest I’d rather have a portable game system turned into a clamp meter :)
