If you haven’t heard from other websites yet, earlier this year a leak of various Nintendo intellectual properties surfaced on the Internet. This included prototype software dating back to the Game Boy, as well as Verilog files for systems up to the Nintendo 64, GameCube and Wii. This leak seems to have originated from a breach in the BroadOn servers, a small hardware company Nintendo had contracted to make, among other things, the China-only iQue Player.
So, that’s the gist of it out of the way, but what does it all mean? What is the iQue Player? Surely now that a company’s goodies are out in the open, enthusiasts can make use of it and improve their projects, right? Well, no. A lot of things prevent that, and there’s more than enough precedent for it that, to the emulation scene, this was just another Tuesday.
Remember the days when computers booted up straight into a BASIC screen, where theoretically you could program yourself a full game without any further software needed? Well, in reality most of us were amused enough making it print “butts” over and over again, but there are those who are adept in the dark arts of making impressive things with such a limited language. [Bugtaro] is one of those people, and to help with his game development in SmileBASIC 4 on the Nintendo Switch, he built himself a dock that turns it into a laptop with an integrated keyboard.
Details on the build are scarce as it’s only outlined in his Twitter account, but there’s enough to give us an idea about what it’s composed of. The Switch slides into the top just like the official dock it comes with, and the laptop shell takes advantage of those functions. Inside it is a 5000 mAh battery to extend the portable life of the whole ensemble, plus a USB hub which gives it its built-in keyboard and allows for a mouse to be plugged in as well. The laptop also gives the Switch its docked TV output mode and can hold the Joy-cons slotted on its sides.
This project would pass for any other case mod here at Hackaday if it weren’t for the fact that [Bugtaro] is in fact a programmer that has been releasing BASIC software on Japanese magazines since the 1980s and worked on several cult classic Mega Drive games with Wolf Team and NexTech during the 1990s. His latest game is GIVERS P3D, a game programmed in SmileBASIC using a 3D engine of his own design and one of the flagship games for the platform. It would be interesting to see if more SmileBASIC programmers end up coming up with their own solutions to aid their development experience following this project.
Can you run Doom on the Amiga? No, not really, and arguably that was one of the causes for the computer’s demise in the mid-90s as it failed to catch up on the FPS craze of the PC world. [Krzysztof Kluczek] of the Altair demogroup has managed not exactly to remedy that status with the original article, but to show us how a potential contender could’ve been designed for the unexpanded Amiga hardware back in the day.
Many developers tried to emulate the thrill and ambiance of the id Software shooter, but they all required high-end Amigas with faster processors and expanded memory, limiting their player base on an already diminished demographic. Not only that, but even with fancier hardware, none of them quite managed to match how well Doom ran on your run-of-the-mill 486 at the time. [Krzysztof] isn’t trying to port Doom itself, but instead creating an engine custom-designed to take advantage of, and minding the limitations of the OCS Amiga as it existed in 1987. The result is Dread, a 2.5D engine that resembles the SNES port of Doom and uses assets from the Freedoom project in order to remain copyright-abiding.
It might not be Doom, but it’s a good peek at what the 33-year old hardware could’ve done in the right hands back then. Technically it already surpasses what the Wolfenstein 3D engine could do, so there’s an idea if someone ever aims to make a straight up port instead of their own game. If you like seeing Doom run on machines it wasn’t meant to, boy do we have some posts for you. Otherwise, stick around after the break for two videos of Dread’s engine being demonstrated.
You may find yourself living in interesting times. The world we knew two months ago is gone, and there is time enough at last, to finally go through those projects we’ve been putting off for one reason or another. Today, I wanted to explore and possibly repair an old unidentified typewriter that belonged to my late aunt for many decades.
A small disclaimer though, I am not an avid typewriter collector or connoisseur. I enjoy looking at them and using them, but by no stretch of the imagination I want to claim to be an expert in their history or inner workings — I’m a hacker after all. What follows is a layman’s adventure into her first typewriter repair, an exciting tale that explores typewriter anatomy and troubleshooting. Let’s dig in.
With social distancing it can be harder to stay in touch with our relatives, especially those who are elderly and not particularly tech-savvy. Looking for a solution to that end for his own grandmother, [Steve] came up with the idea of using an inexpensive used tablet and a mobile data plan in order to mail her a “video phone” that works out of the box.
Since the tablet is configured to use cellular networks rather than WiFi, it requires no setup process at all to the recipient. And with the Android version of Skype, it’s possible to configure it so that calls are automatically picked up and video chat enabled. That way, whoever gets the tablet after it’s prepared doesn’t have to tap a single button on the screen in order to receive a call.
[Steve] has also developed the simple idea into a full-fledged easy-to-follow tutorial so that just about anyone is able to replicate the process for their own loved ones. And if you’re still having any trouble with it, there’s a team of volunteers right on the website who can help you with tech support. Just remember to disinfect whatever device you’re sending, since viruses can typically stick to surfaces like plastic and glass for longer.
Now, if showing up to your relatives as a disembodied video screen doesn’t cut it for you, then you might want to send them something more substantial like this cute little telepresence robot that can drive around on a desk.
If you’re going outside (only for essential grocery runs, we hope) and you’re having trouble measuring the whole six feet apart from other people deal by eye, then [Guido Bonelli] has a solution for you. With a standard old HC-SR04 ultrasonic sensor, an audio module and a servo to drive a custom gauge needle he’s made a device which can warn people around you if they’re too close for comfort.
As simple as this project may sound like for anyone who has a bunch of these little Arduino-compatible modules lying around and has probably made something similar to this in their spare time, there’s one key component that gives it an extra bit of polish. [Guido] found out how intermittent the reliability of the ultrasonic sensor was and came up with a clever way to smooth out its output in order to get more accurate readings from it, using a bubble sort algorithm with a twist. Thirteen data points are collected from the sensor, then they are sorted in order to find a temporal middle point, and the three data points at the center of that sort get averaged into the final output. Maybe not necessarily something with scientific accuracy, but exactly the kind of workaround we expect around these parts!
Just because something doesn’t seem to have an apparent purpose, that doesn’t mean we shouldn’t try making it anyway. As flexible PCBs become cheaper and easier to order from low-scale fab houses, we’re seeing hobbyists experiment with new uses for them such as [Carl Bugeja]’s jumping circuit.
The circuit is based a coil printed on the flexible PCB itself acting as an electromagnet, but unlike other designs which use the same trick, in this one the coil is made to be the static side of an actuator. Attached to the circuit with folding arms is a stack of two permanent magnets, which work as the moving part. Since the magnets make up most of the mass of the circuit, as they’re pushed down and sprung back up, it causes the whole thing to leap around just under one centimeter off the table like a little electric grasshopper.
This is far from [Carl]’s first appearance here on Hackaday, and he’s been clearly busy exploring new uses for flexible PCBs with their properties as electromagnets, from making POV displays with them to small robots that move around through vibration. We’re excited to see what else he can come up with, and you can see this one in action after the break.
