A Keypad Joypad For Your Retro Gaming

April 1, 2016 by Jenny List 15 Comments

[TK] is a retro computer enthusiast who’s had some difficulty locating a joystick for his trusty Amiga 500. New ‘sticks are expensive, and battered survivors from the 80s go for more than they should.

Happily these old controllers were simple devices, having only five control lines for the four directions and a fire button which were active low. [TK] therefore cast around the available components and decided to craft his own controller from a numerical keypad.

Numerical keypads may be ubiquitous, but they’re not the perfect choice for a joypad. Instead of individual switches, they are wired as a matrix. [TK]’s controller works within that constraint without butchering the keypad PCB, though his layout has the left and right buttons below the up and down buttons. Looking at the schematic we wonder whether the 4-5-6 and 7-8-9 rows could be transposed , though joypad layout is probably a matter of personal choice.

Making the controller was a simple case of wiring the pad to a 9-pin D socket in the correct order, and plugging it into the Commodore. He reports that it’s comfortable to use and better than some of the lower-quality joysticks that were on the market back in the day. Veterans of Amiga gaming will understand that sentiment, there were some truly shocking offerings to be had at the time.

Quite a few home-made game controllers have made it onto these pages over the years. There is this one using tactile switches and a ballpoint pen, and a stick made from the idler wheel from a surplus VCR, but the ultimate crown of junkbox joysticks should go to this joystick made from clothes pins. If we take one thing away from all this home-made controller ingenuity, it is that what really matters is not the hardware but the gameplay.

There are dozens of different 3D printable cases out there for the Raspberry Pi, but the BeagleBone Black, as useful as it is, doesn’t have as many options. The folks at 3D hubs thought they could solve this with a portable electronics lab for the BBB. It opens like a book, fits a half-size breadboard inside, and looks very cool.

The guy who 3D printed his lawnmower has a very, very large 3D printer. He now added a hammock to it, just so he could hang out during the very long prints.

There’s a box somewhere in your attic, basement, or garage filled with IDE cables. Wouldn’t they be useful for projects? Yep, only not all the wires work; some are grounds tied together, some are not wired straight through, and some are missing. [esot.eric] has the definitive guide for 80-wire IDE cables.

Like case mods? Here’s a golden apple, made out of walnut. Yes, there are better woods he could have used. It’s a wooden replica of a Mac 128 with a Mac Mini and LCD stuffed inside. Want a video? Here you go.

If you have a 3D printer, you’re probably familiar with PEEK. It’s the plastic used as a thermal break in non-all-metal hotends. Now it’s a filament. An extraordinarily expensive filament at €900 per kilogram. Printing temperature is 370°C, so you’ll need an all-metal hotend.

It’s the Kickstarter that just keeps going and going and going. That’s not a bad thing, though: there really isn’t much of a market for new Amiga 1200 cases. We’ve featured this project before, but the last time was unsuccessful. Now, with seven days left and just over $14k to go, it might make it this time.

One more go at new enclosures for the Amiga 1200. Yes, it’s a Kickstarter campaign, and we mentioned ~~a similar~~ the same campaign last month. The previous campaign received a little more than half of the desired funding in a 30-day campaign. The new campaign received half its funding in a week. The only difference? Now you can put a Raspberry Pi in a newly manufactured A1200 case. And they say Raspberry Pi consumerism isn’t a thing…

Cheap SLA printing service. [Ian] and Dangerous Prototypes have made a name for themselves with dirt cheap, acceptable quality PCBs. Now they’re going for custom prints on a resin machine. It’s $0.95 per gram (density is 1.3g/cc). That’s cheap.

[James Willis] built a floppy drive orchestra. There are 16 drives in this orchestra, all controlled by an FPGA. Here’s the writeup.

Here’s a video overview of a real, huge, rideable hexapod robot. ‘Wow’ is just about the only thing we got for this.

Western Digital introduced a hard drive made specifically for the Raspberry Pi. It’s a hard drive with a USB interface, and a USB cable that connects to the Pi, the drive, and a power adapter. In other news, externally powered USB hard drives exist. You can buy a 2TB drive for the price of the 1TB PiDrive. What was that thing about Raspi consumerism?

Next week is the Open Hardware Summit in Philadelphia. We’ll be there (or rather, I will). We’ll have a post on the OHS badge up on Monday. Would anyone like to go see the lady made out of soap? It’s right around the corner from the venue.

Over the last few years, Maker’s Asylum in Mumbai has grown from a garage to a very well stocked workspace with 140 members. They’re getting kicked out at the end of the month and they need some help. We just had a meetup at the Delhi branch of Maker’s Asylum, and these guys and gals are really cool.

Speaking of crowdfunding campaigns for hackerspaces, South Central Pennsylvania might be getting its own hackerspace. The 717 area code is a vast wasteland when it comes to anything anyone reading Hackaday would consider interesting, despite there being plenty of people who know their way around CNC machines, soldering irons, and welders. This needs to happen.

Need some help with Bluetooth standards? Tektronix has you covered with a gigantic poster of the physical layer. If only there were a repository of these handy, convenient reference posters.

Forgings and castings make for great YouTube videos, and this aluminum bell casting is no exception. There’s about 18 pounds of aluminum in there, which is pretty large as far as home casting goes.

Electronic Goldmine has an assortment of grab bags – spend a few dollars get a bag of chips, LEDs, diodes, or what have you. What’s in these grab bags? [alpha_ninja] found out. There’s some neat stuff in there, except for the ‘SMD Mixture’ bag.

Remember the found case molds for the Commodore 64C that became a Kickstarter? It’s happening again with the Amiga 1200. This is a new mold with a few interesting features that support the amazing amount of upgrades that have come out for this machine over the years. Being new molds, the price per piece is a little high, but that’s your lesson in manufacturing costs for the day.

This Little Amiga Still Runs School District’s HVAC

It’s the rare tech worker that manages a decade in any one job these days – employee loyalty is just so 1980s. But when you started your career in that fabled age, some of the cultural values might have rubbed off on you. Apparently that’s the case for an Amiga 2000 that’s been on the job since the late ’80s, keeping the heat and AC running at Grand Rapids Public Schools (YouTube video link.)

The local news story is predictably short on details and pushes the editorial edge into breathless indignation that taxpayer dollars have somehow been misspent. We just don’t see it that way. “If it ain’t broke, don’t fix it,” is somewhat anathema to the hacker ethos. After all, there’s no better time to “fix” something than when it’s working properly and you can tell if you’ve done something wrong. But keeping an important system running with duct tape and wire ties is also part of the hacker way, so we applaud [Tim Hopkins] and his colleagues at the GRPS Facilities and Operations Department for their efforts to protect the public purse. And a round of applause is also due not only to the Amiga design team, who produced a machine that can run for nearly three decades, but also to Johnson Controls, whose equipment – apparently a wide area radio modem linking the HVAC systems in the district’s buildings – is being run by The Little Amiga That Could. Sounds like they built stuff to last way back when.

So when this machine is finally retired, here’s hoping they give it a good sendoff. Perhaps we’ll see it with some other Amigas at some future Vintage Computer Festival. Or maybe it’ll be one of those active retirees and start a career in the music industry.

[Thanks Thinkerer!]

Hackaday Retro Edition: Androids And Amigas

July 12, 2015 by Brian Benchoff 20 Comments

Tiny ARM boards are everywhere, and if the Raspberry Pi is any indication, they’re mostly used for emulating old consoles and computers. With only a $30 single board computer, it’s easy to emulate an SNES, Apple II, C64, or any of the other piece of classic 80s or 90s hardware.

Understandably, there will eventually be a few projects and products that hope to capitalize on this retro trend. Few of them will go through the rigamarole of actually licensing the relevant IP. The Armiga is one of these projects. It’s an emulated Amiga 500 with 1MB of RAM packaged in what looks like a 3.5″ external floppy drive.

Inside this tiny little box is a dual core ARM for Amiga emulation. For the most part, this is just a basic Android system, but the real selling point of this system is the Armiga Project software. This is a full emulator and game browser that also includes a legal (!) copy of Kickstart 1.3. The ‘upscale’ version of the Armiga also includes a floppy disk controller and drive, should you ever want to dump all those old floppies sitting around in your attic.

This isn’t the first time we’ve heard about the Armiga. It was a crowdfunding campaign a year ago that was unsuccessful for reasons we can’t comprehend. The creators of the Armiga have forged on, and now these tiny little boxes of guru meditation have started shipping. The Beta units have sold out and there’s a waiting list for more.

VCF East X: Amigas And Non-Apple Macs

April 22, 2015 by Brian Benchoff 13 Comments

The Amiga 1000, the original Amiga, was introduced in 1985, making this the 30th anniversary of the Commodore Amiga. Of course this needed to be represented at the Vintage Computer Festival, and [Bill Winters] and [Anthony Becker] were more than up to the task:

The guys brought with them a representation of nearly every Amiga, and also have a few neat gadgets to plug into these cool little boxes. The Amiga 1200 has been heavily upgraded with a compact flash drive. With the proper adapters and cards, this neat machine can be upgraded with Ethernet, WiFi, or just about every conceivable networking solution.

Attached to the A500 is a Gotek floppy drive emulator, a relatively standard if weird device that turns a PC floppy drive connector into a USB mass storage solution. This floppy emulator did not originally support Amiga disk formats, but with a firmware modification, everything just works. That’s a great story in itself, and something we should probably cover another time.

If you’re wondering what it was like for [Bill] and [Anthony] to dig through their garage for their exhibit, here you go.

Portable Macintoshen

The first Macintosh was released in 1984. Macintosh users wanted a slightly more portable machine, but the first ‘luggable’ Mac wouldn’t be released until late 1989. The market was there to fill the gap, with some bizarre machines exhibited by [Matt Bergeron]:

The Outbound laptop and notebook were unlicensed clones of the Macintosh. Instead of pirating the Apple ROMs, the Outbound computers required buyers to pull the ROM chips from their Macs and install them in the slightly more portable version. This was, of course, inconvenient, and we can imagine there were more than a few ROM chips cloned.

The Dynamac was a different beast, using the entire PCB from a mac SE or SE/30. To this, the creators of the Dynamac added a custom video card and electroluminescent display that was also capable of driving an external monitor. Very cool stuff.
