Cheese Grater Now Grates Cheese

September 9, 2019 by Bryan Cockfield 11 Comments

If you’ve been using Apple products since before they were cool, you might remember the Power Mac G5. This was a time before Apple was using Intel processors, so compatibility issues were high and Apple’s number of users was pretty low. They were still popular in some areas but didn’t have the wide appeal they have now. The high quality of the drilled aluminum design lived on into the Intel era and gained more popularity, but the case was still colloquially known as the “Cheese Grater”. Despite not originally being able to grate cheese though, this Power Mac actually does grate cheese.

Ungrated cheese is placed in the CD drive slot where it passes through a series of 3D printed gears which grate the cheese into small chunks. The cheese grating drive is automatically started when it detects cheese via a Raspberry Pi. The Pi 4 also functions as a working desktop computer within the old G5 case, complete with custom-built I/O ports for HDMI that integrate with the case to make it look like original hardware.

Funnily enough, the Pi 4 has more computing power and memory than Apple’s flagship Mac at the time, and consumes about 100 times less power. It’s a functional build that elaborates on an in-joke in the hardware community, which we can all appreciate. Perhaps the next build should be something that uses the blue smoke for a productive purpose. Meanwhile, regular readers will remember that this isn’t the first Apple related cheese grating episode we’ve shown you.

Hackaday Links: June 30, 2019

In our continuing series of, ‘point and laugh at this guy’, I present a Kickstarter for the, “World’s First Patented Unhackable Computer Ever”. It’s also a real web site and there’s even a patent (US 10,061,923, not showing up on Google Patents for some reason), and a real product: you can get an unhackable laptop, and you can get it in either space gray or gold finish. This gets fun when you actually dig into the patent; it appears this guy invented protected memory, with one section of memory dedicated to the OS, and another dedicated to the browser. This is a valid, live patent, by the way.

The 2019 New York Maker Faire is off. Yeah, it says it’s still going to happen on the website, but trust me, it’s off, and you can call the New York Hall of Science to confirm that for yourself. Maker Media died recently, and there will be no more ‘Flagship’ Maker Faires. That doesn’t mean the ‘mini’ and ‘featured’ Maker Faires are dead, though: the ‘Maker Faire’ trademark is simply licensed out to those organizers. In the next few weeks, there is going to be a (mini) Maker Faire in Coeur d’Alene, Idaho, Gilroy, California, Edmonton, Alberta, Kingsport Tennessee, and a big ‘ol one in Detroit. This raises an interesting question: where is the money for the licensing going? I’m sure some Mini Maker Faire organizers are reading this; have your checks been cashed? What is the communication with Maker Media like?

Just because you can, doesn’t mean you should. It’s valuable words of wisdom like that and can apply to many things. Commenting on blog posts, for example. Yes, you can throw sticks at a wasp’s nest, that doesn’t mean you should. Yes, you can 3D print Heely adapters for your shoes, but it doesn’t mean you should. It does look dope, though and you’re automatically a thousand times cooler than everyone else.

The C64 Mini is a pocket-sized Linux device with an HDMI port meant to play C64 games. There were high hopes when the C64 Mini was announced, but it turned out the keyboard isn’t actually a mini keyboard. Now someone had the good sense to combine one of these ‘smartphone chips running an emulator in a retro case’ products with a full-sized keyboard. The C64 will be around by Christmas, and yeah, it has a full working keyboard.

Thinkpads are great, especially the old ones. You find a T420, and you can have a battery hanging off the back, a battery in the optical drive bay, and for some old Thinkpads, there’s a gigantic ‘slice’ battery that doubles the thickness of your laptop. Here’s the most batteries in a Thinkpad ever, with the requisite reddit post. It’s 27 cells, with an all-up capacity of 212 Watt-hours. There are two interesting takeaways from the discussion here. First, this may, technically, be allowed on a commercial flight. The FAA limit is 100 Watt-hours per battery, and the Ultrabay is a second battery. You’re allowed two additional, removable batteries on a carry on, and this is removable and reconfigurable into some form that the TSA should allow it on a plane. Of course no TSA agent is going to allow this on a plane so that really doesn’t matter. Secondly, the creator of this Frankenpad had an argument if Hatsune Miku is anime or not. Because, yeah, of course the guy with a Thinkpad covered in Monster energy drink stickers and two dozen batteries glued on is going to have an opinion of Miku being anime or not. That’s just the way the world works.

Prices for vintage computers are now absurd. The best example I can call upon is expansion cards for the Macintosh SE/30, and for this computer you have a few choice cards that have historically commanded a few hundred dollars on eBay. The Micron XCEED Color 30 Video Card, particularly, is a special bit of computer paraphernalia that allows for grayscale on the internal monitor. One of these just sold for two grand. That’s not all, either: a CPU accelerator just sold for $1200. These prices are double what they were just a few years ago. We’re getting to the point where a project to reverse engineer and produce clones of these special cards may make financial sense.

The biggest news in consumer electronics this week is the Playdate. It’s a pocket game console that has a crank. Does the crank do anything? No, except that it has a rotary encoder, so this can nominally be used for games. It will cost $150, and there are zero details on the hardware other than the industrial design was done by Teenage Engineering. There’s WiFi, and games will be delivered wireless on a weekly basis. A hundred thousand people are on the wait list to buy this.

If you want a pick and place in your garage workshop, there aren’t many options. There’s a Neoden for about ten grand, but nothing cheaper or smaller. The Boarditto is a two thousand dollar pick and place machine that fits comfortably on your desk. It has automatic tape feeders, a vision system, and for the most part it looks like what you’d expect a small, desktop pick and place machine to be. That’s all the information for now, with the pre-order units shipping in December 2019.

Unobtanium Bezels Finally Modeled For 3D Printing

January 19, 2019 by Brian Benchoff 26 Comments

In 1991, Apple released the Quadra line of computers, named after their utilization of the new Motorola 68040 CPU. The Quadra line initially consisted of two models, the Quadra 700 and the Quadra 900. These two models, and the Quadra 950, released as a slight upgrade to the 900, were the peak of performance. You could conceivably load these machines up with 256 Megabytes of RAM, in an era where hard drives hovered around 80 Megabytes. This much RAM would cost as much as a house. These were powerhouses, the first ProTools workstations, and they ran Jurassic Park. If you wanted peak performance in the early 90s, you got a Quadra.

The Quadra 900 and 950 were tower computers, and there were options for floppy, Zip drives, Bernoulli drives, and a CD-ROM drive. They were introduced a little before the ‘multimedia’ hubub, and right now, the plastic bezel for the CD-ROM option is an absurdly expensive piece of plastic. People have paid $150 for an original CD-ROM bezel. Seems like the perfect application of 3D printing, doesn’t it? That’s exactly what [360alaska] over on the 68k Macintosh Liberation Army forms did. The unobtanium bezel can now be sent off to Shapeways.

This project is a continuation of a thread where various forum members shared their .STLs for random bits of Apple plastic, ranging from rubber feet for PowerBooks to the clip-on ‘programmer’s switch’ for the Macintosh SE. The crowning achievement of this community endeavour is the Quadra 950 CD-ROM bezel. There are a few varieties, ranging from one that fits a standard 5 1/4″ drive, to a nearly exact replica of the official Apple offering for their official drive. All the files are there for the downloadin’.

Printing these bezels will be a bit of a challenge for a filament-based printer, but resin printers are getting cheap and Shapeways is always there for you. Painting to match the brominated patina of old plastic is also a challenge, but the forum members have had some success with off-the-shelf spray paints.

Upgrade Your Mac With A Touchscreen, For Only A Dollar

April 5, 2018 by Jenny List 77 Comments

Imagine how hard it could be to add a touch screen to a Mac laptop. You’re thinking expensive and difficult, right? How could [Anish] and his friends possibly manage to upgrade their Mac with a touchscreen for only a dollar? That just doesn’t seem possible.

The trick, of course, is software. By mounting a small mirror over the machine’s webcam, using stiff card, hot glue, and a door hinge. By looking at the screen and deciding whether the image of a finger is touching its on-screen reflection, a remarkably simple touch screen can be created, and the promise of it only costing a dollar becomes a reality. We have to salute them for coming up with such an elegant solution.

They have a video which we’ve put below the break, showing a few simple applications for their interface. Certainly a lot less bother than a more traditional conversion.

Jeroen Domburg Miniaturizes A Mac

November 27, 2017 by Dan Maloney 20 Comments

His name may not ring a bell, but his handle will — Sprite_tm, a regular to these pages and to Hackaday events around the world. Hailing from The Netherlands by way of Shanghai, Jeroen Domburg dropped by the Hackaday Superconference 2017 to give a talk on a pet project of his: turning a Macintosh into, well, a pet.

You could say this is Jeroen’s second minification of vintage hardware. At last year’s Hackaday Superconference, he brought out the tiniest Game Boy ever made. This incredible hardware and software hack stuffs a complete Game Boy into something you can lose in your pocket. How do you top a miniature version of the most iconic video game system ever made? By creating a miniature version of the most iconic computer ever made, of course.

The tiny object in front of Jeroen in the title image is, in fact, a working Macintosh Plus that he built. Recreating mid-80’s technology using 2017 parts seems like it would be easy, and while it’s obviously easier than breaking the laws of physics to go the other direction, Jeroen faced some serious challenges along the way, which he goes into some detail about in his talk.

The Other Way To Brick A Mac Classic

April 5, 2017 by Dan Maloney 7 Comments

Why would you build a mini Mac Classic using LEGO and a Raspberry Pi? Well, why wouldn’t you?

[Jannis Hermanns] couldn’t find a reason to control this outburst of nostalgia for the good old days of small, expensive computers and long hours spent clawing through the LEGO bin to find The Perfect Piece to finish a build. It turns out that the computer part of this replica was the easy part — it’s just an e-paper display driven by a Raspberry Pi Zero. Building the case was another matter, though.

After a parti-colored prototype with whatever bricks he had on hand, a session of LEGO Digital Designer led him to just the right combination of bricks to build an accurate case, almost. It turns out that the stock selection of bricks in LDD won’t allow for the proper proportions for the case, so he ordered the all-white bricks and busted out the Dremel. LEGO purists may want to avert their eyes from the ABS gore within, but in the end the case worked out and the whole build looks great.

Fancy a full-size Mac Classic reboot? How about this iPad docking station? Or if tiny and nostalgic is really your thing, this retro-future terminal build is pretty keen too.
