Creative Limitation And The Super Nintendo Sound Chips

July 31, 2019 by Bryan Cockfield 18 Comments

The Super Nintendo recently experienced a surge in popularity, either from a combination of nostalgic 30-somethings recreating their childhoods, or because Nintendo released a “classic” version of this nearly-perfect video game system. Or a combination of both. But what made the system worthy of being remembered at all? With only 16 bits and graphics that look ancient by modern standards, gameplay is similarly limited. This video from [Nerdwriter1] goes into depth on a single part of the console – the sound chips – and uses them to illustrate a small part of what makes this console still worth playing even now.

The SNES processed sound with two chips, a processing core and a DSP. They only had a capacity of 64 kb, meaning that all of a game’s sounds and music had to fit in this tiny space. This might seem impossible if you’ve ever played enduring classics like Donkey Kong Country, a game known for its impressive musical score. This is where the concept of creative limitation comes in. The theory says that creativity can flourish if given a set of boundaries. In this case it was a small amount of memory, and within that tiny space the composer at Rare who made this game a work of art was able to develop a musical masterpiece within strict limitations.

Even though this video only discusses the sound abilities of the SNES, which are still being put to good use, it’s a good illustration of what made this system so much fun. Even though it was limited, game developers (and composers) were able to work within its limitations to create some amazingly fun games that seem to have withstood the test of time fairly well. Not all of the games were winners, but the ones that were still get some playtime from us even now.

Run Your Own Phone To Bring The Dreamcast Back Online

July 31, 2019 by Bryan Cockfield 17 Comments

Playing a video game online is almost second nature now. So much so that almost all multiplayer video games have ditched their split-screen multiplayer modes because they assume you’d rather just be alone at your house than hanging out with your friends. This wasn’t always the case though. In the early days of online multiplayer, systems had to rely on dial-up internet before broadband was readily available (and still had split screen if you didn’t even have that). Almost no one uses dial up anymore though, so if you still like playing your old Dreamcast you’re going to have to do some work to get it online again.

Luckily for all of us there’s a Raspberry Pi image to do almost anything now. This project from [Kazade] uses one to mimic a dial-up connection for a Dreamcast so you can connect with other people still playing Quake 20 years later. It’s essentially a network bridge, but you will need some extra hardware because phone lines use a high voltage line that you’ll have to make (or buy) a solution for. Once all the hardware is set up and working, you’ll need to make a few software configuration changes, but it’s a very straightforward project.

Granted, there have been ways of playing Dreamcast games online before, but this new method really streamlines the process and makes it as simple as possible. The Dreamcast was a great system, and there’s an argument to be made that the only reason it wasn’t more popular was that it was just slightly too far ahead of its time.

Thanks to [Rusty] for the tip!

Copy Protection In The 80s, Showcased By Classic Game Dungeon Master

June 25, 2019 by Donald Papp 45 Comments

Making a copy of a purchased game used to be as simple as copying a disk. As the game industry grew, so did fear of revenue loss which drove investment in countermeasures. These mainly consisted of preventing the easy duplication of magnetic diskettes, or having users jump through tiresome hoops like entering specific words from the printed manual. These measures rarely posed much of a challenge to the dedicated efforts of crackers, but the copy protection in the classic 80s game Dungeon Master for the Atari ST and Amiga was next-level. It implemented measures that went well beyond its contemporaries, and while it was eventually defeated, it took about a year to happen. In an era where games were cracked within days or even hours of release, that was remarkable.

Dungeon Master was a smash hit at the time, and while the details of its own brand of what we would now call DRM may not be new, this video presentation by [Modern Vintage Gamer] (YouTube link) does a wonderful job of stepping through everything it did, and begins with an informative tour of copy protection efforts of the era for context.

The video is embedded below, but if you’d like to skip directly to the details about Dungeon Master, that all starts just past eight minutes in. What we now call DRM clearly had roots that preceded the digital world of today; an absurd timeline in which even cat litterboxes can have DRM.

Homebrew Laptop Makes A Statement With A Steampunk Theme

June 9, 2019 by Dan Maloney 15 Comments

Some may argue, but your choice of computing hardware says exactly zero about you, at least when you buy off the shelf. Your laptop or PC is only one of millions, and the chances of seeing someone with the exact same machine are pretty good. If you want to be different, you really need to build something yourself.

This homebrew steampunk laptop does a great job at standing out from the crowd. [Starhawk]’s build is an homage to the Steampunk genre, in a wooden case with brass bits and bobs adorning. The guts are based on an Intel motherboard, a bit dated but serviceable enough for the job. There’s a touch-capable LCD in the lid, and we absolutely love the look of the keyboard with its retro-style chrome and phenolic keycaps. Exposed USB cables run to and fro, and the braided jackets contribute to the old-timey look. The copier roller as a lid hinge is a nice touch too.

[Starhawk]’s build log is long and detailed, and covers the entire build. We’ve seen interesting builds from him before, like this junk-bin PC build for a friend in need. Looks like this one is for personal use, though, and we can’t blame him.

Vintage Monoscope Tubes Generate Classic TV Test Patterns Once Again

May 26, 2019 by Dan Maloney 16 Comments

Night creatures and insomniacs of a bygone era may fondly recall a TV test pattern appearing once [Jack Parr] or [Steve Allen] had had their say and the local TV station’s regular broadcast day had concluded. It was affectionately known as the Indian Head test pattern, for the stylized Native American, resplendent in a feathered headdress, that featured prominently in the graphic.

Unknown to most viewers was exactly how that test pattern and others like it were generated. But thanks to [Rich “The Lab Guy” Diehl] and his monoscope restoration project, we can all share in the retro details. It turns out that while some test patterns were merely a studio camera trained on a printed card, most were generated by a special tube called a monoscope. It functioned in basically the same manner as a studio camera, but rather than scanning the incident light of a scene with an electron beam, the image was permanently etched into a thin aluminum plate. [Rich] laid hands on two vintage monoscope tubes, one containing the Indian Head test pattern, and set about building a device to use them. “The Chief” can hold either tube in a Faraday cage of thin, flexible PCB material and 3D-printed parts, with supporting electronics like the power supply and video amplifiers in an aluminum chassis below.

It’s a nice piece of work and a great lesson in how it used to be done, and the lithophane of the Indian head is a nice touch. Hats off to [The Lab Guy] for build quality and great documentation, including a detailed video series that starts with the video below. If you need a little more background on how video came to be, [Philo Farnsworth]’s story is a good place to start.

The Raspberry Pi Portable Console You Wish You Had

May 16, 2019 by Brian Benchoff 35 Comments

A retro game console is a fun all-arounder project. You’ve got electronics, mechanical design, and software considerations. For this year’s Hackaday Prize, is going all in. The Portable Retro Game Console with 7.9-inch Display is a work of art, and everything that a retro console could be.

This build is based on the Raspberry Pi 3 A+ instead of the B model for space-saving considerations. The screen is a beautiful 7.9 inch IPS panel with 2048 x 1536 resolution. Stereo 3 W speakers pump out the tunes, and an 8000 mAh provides somewhere between 3 and 6 hours of play time.

While using a Raspberry Pi 3 for retro gaming is fun, there’s a world of oppurtunity for emulating bigger and badder consoles thanks to more powerful single board computers. The Nvidia Jetson Nano is far more powerful than the Raspberry Pi 3, and could conceivably emulate N64 and PlayStation games. The Atomic Pi, the fantastic computer that totally isn’t industrial surplus repackaged as an educational computer, already is proven to emulate N64 games. Imagine taking a portable console out of your backpack and playing Conker’s Bad Fur Day on the bus. Oh, that’s cheeky, but it is possible thanks to the amazing work of hardware creators.

Video Doorbell Focuses On Quality, Aesthetic

May 13, 2019 by Lewin Day 2 Comments

One of the most popular futurist tropes of the 20th century was the video intercom. Once this technology was ready, it would clearly become a mainstay of modern living overnight. Our lived reality is however somewhat different. For [MisterM], that simply wouldn’t do, so he set about producing a retro-themed video doorbell that is sure to be the envy of the neighbourhood.

Not one to settle for second best, [MisterM] wanted to focus on quality in video and sound. A Microsoft LifeCam 3000HD handles video and audio capture, with a Raspberry Pi 3B+ providing plenty of grunt to run the show. The Pimoroni pHAT BEAT add-on provides audio output. It’s all integrated into a 1980s vintage intercom, which is painted a deep shade of maroon for an extra classy look. Further parts are integrated into a classic Sony tape deck, with LEDs shining out from under the cassette door for added visual appeal.

The doorbell works by making calls to Google Duo, which allows the user to answer the door from anywhere in the house, or indeed – anywhere with an Internet connection! [MisterM] reports this has already proved useful for communicating with couriers delivering packages to the house. There’s also a standard wireless doorbell and chime integrated into the unit which alerts those within the house in the usual way.

It’s a project that is both highly functional and looks particularly swish. Integrating new brains into old-school enclosures is a great way to give your project a cool look. These aircraft surplus clocks are a great example. Video after the break.
