Okay so i took a little break from making SL stuff to work on something i really wanted to do for a very long time but never had enough time, motivation and know how to do it, but im glad i finally did because this was so fun and refreshing, i love doing new things i never did before, this is the biggest electronics project i ever had.

So what this is this project about, its a handheld NES console, a handheld famiclone to be exact. Famiclones are unauthorized chinese clones of nintendo’s famicom (also known as NES in the rest of the world) hardware, they use famicom cartrige format and are compatible with both original famicom/NES games and pirated chinese multi game carts.

The famiclone hardware has advanced and went a long way over the years in in a never ending drive of production cost savings and corner cutting, while the old famiclones form the 80s and early 90s tried to closely recreate the original famicom hardware, mid by mid to late 90s technology has progressed enough for them to be able to cheaply cram the whole famicom architecture on a single chip called NOAC (NES-on-a-chip) making the hardware very compact and cheep to manufacture. (Now days you can get a famiclone for 16 euros and games cost 3 euros)

NOAC

The main board of a famiclone is compact enough that it gave me an idea, what if i could slap a screen on it and some batteries and a controller and make it portable, it would be so cool to have a portable NES, no need to fiddle around with no emulators, it would be the real deal, just pop a game cart in and play mario or tanks or whatever, but i had no idea where to get a screen or the technical know how to actually do it, so i shelved this idea in my mind for a few years till one day i accidentally came across a tiny screen for car rear view cameras on ebay.

I noticed that it accepts the standard composit video signal and that made a light bulb light up in my head, what if i could use this for my portable NES idea, so i bought the screen, which was also dirt cheep, but i still had no idea how i would even power this system or package it, i didnt have a 3D printer yet back then so i shelved this idea for a little longer till a few years ago i got myself a 3D printer and one day i was watching a youtube video about 3phase power and in it they mentioned step down convertors which was that last piece of the puzzle that i needed to get this project of the ground.

So i got all the stuff i need and i began testing my ideas by just hooking everything up on the table to see if it even works. The screen needed 12volts while the console needed 9volts, this is where the step down convertor came into play, splitting the power up between the screen and the console. I also needed some kind of 12volt battery, but all the batteries i could find were too big for a handheld, but i came across a battery clip that lets you just combine 8 1.5v AA batteries into one big 12v battery.(i will get into why it needs 12v later down)

Once i got everything working, i started designing the look of it and thinking about how to fit all the components inside it as well, once i had a basic idea of what it would look like, i measured every part and recreated it in 3D so that i could than model the case around it and 3D print it with enough precision for the parts to actually fit.

Fitting all the components inside it was the most fun part, i had to fabricate a lot of the internal components as well, like a controller board with an audio out and a sound circuit that amplifies the sound and outputs it through internal speaker or headphones, with volume control and selection switch.

I Was finally done wiring everything up and doing some final output tests before i put everything together, i was jizzing my pants in excitement to see everything work.

And after a whole week of not shaving and letting dishes pile up, it was finally done ! just like that i had made my own handheld console, this is the best feeling in the world. my hands were shaking in excitement to play it and show it of xD

BTW Its a 50hz/25fps PAL console so games that arent optimized for the PAL region run slower than they do on NTSC consoles

So what are my future plans for this console? well first of all, making it use less batteries, right now it runs on 8 batteries but later on i will make it run on just 4 since i figured the screen itself doesnt actually need that much power and all i need to do is just desolder a power regulator chip and connect the power directly, the actual power requirement for this screen is 4.5v to 6v, the only reason its made to accept 12v is because its ment to be used in cars, the famiclone board itself only needs 4.5 volts as well, and the sound chip im using also can work with 4.5 so it would be really cool if i could hook everything up on just 3 AA batteries. Once that is done, im going to refine the insides of case a little more because its very difficult to put it together and close it up without wires getting in the way, also still need to make a proper reset button and a volume adjust knob and color the metal bar on the screen black cuz it fucks with the whole design of the screen border. Once all that is done, i will get some professional 3D printing company to print me a few copies of the case and make more of these, i also have ideas on how to make a link cable for 2 of them to play 2 player games, i also have an idea on how to make it even more portable with a PSP/Vita style screen and control layout, and since nintendo’s patents on the hardware have expired, i can probably make and sell a bunch of these if i manage to source the parts cheaply, ill see how it goes, but right now i wanna get back to making SL stuff.

    the Manime head next?

    I’m curious if you think it will be possible to reverse venus on it? people use venus for man, use man anime head as a girl head ? #just a thought

    Im always interested if any plans for new stuff after that?

    Thanks

    This is super cool Util :D I never realized how handy you were with tech stuff like this. Seems you’ve been busy! Pocket bikes, gameboy mods… I’m… a bit envious of how cool you are, but inspiring nonetheless. Keep up the good work!

  4. I have to admit this is pretty cool and a neat process to read through. How much did it cost to create your prototype?
