VCF: The Guys Keeping Up With Commodore

April 2, 2017 by Brian Benchoff 33 Comments

This year at the Vintage Computer Festival, war was beginning. The organizers of the con pulled a coup this year, and instead of giving individual exhibitors a space dedicated to their wares, various factions in the war of the 8-bitters were encouraged to pool their resources and create the best exhibit for their particular brand of home computers. The battle raged between the Trash-80 camp and the Apple resistance. In the end, only one home computer exhibit would remain. Are you keeping up with Commodore? Because Commodore is keeping up with you. This exhibit from [Anthony Becker], [Chris Fala], [Todd George], and [Bill Winters] among others is the greatest collection of Commodore ever assembled in one place.

This year’s Commodore exhibit was a free for all of every piece of the hardware Commodore (or Zombie Commodore) has ever produced. Remember netbooks? Commodore made one. Remember when people carried dedicated devices to play MP3s? Commodore was there. Did you know you can spend $20,000 USD on a 30-year-old computer? That’s Commodore.

VCF East: Before There Was Arduino, We Had Balls

April 2, 2017 by Brian Benchoff 13 Comments

Today, if you want to teach kids the art of counting to one, you’re going to drag out a computer or an iPad. Install Scratch. Break out an Arduino, or something. This is high technology to solve the simple problem of teaching ANDs and ORs, counting to 0x0F, and very basic algorithms.

At the Vintage Computer Festival East this year, System Source, proprietors of a fantastic museum of not-quite-computing equipment brought out a few of their best exhibits. These include mechanical calculators, toys from the 60s, and analog computers that are today more at home in a CS departments’ storage closet than a classroom. It’s fantastic stuff, and shows exactly how much you can learn with some very cleverly designed mechanical hardware.

VCF: 3D Printing In The 80s

April 2, 2017 by Brian Benchoff 28 Comments

The Vintage Computer Festival East is going down right now, and I’m surrounded by the height of technology from the 1970s and 80s. Oddly enough, Hackaday frequently covers another technology from the 80s, although you wouldn’t think of it as such. 3D printing was invented in the late 1980s, and since patents are only around for 20 years, this means 3D printing first became popular back in the 2000’s.

In the 1970s, the first personal computers came out of garages. In the early 2000s, the first 3D printers came out of workshops and hackerspaces. These parallels pose an interesting question – is it possible to build a 1980s-era 3D printer controlled by a contemporary computer? That was the focus of a talk from [Ethan Dicks] of the Columbus Idea Foundry this weekend at the Vintage Computer Festival.

A Wallflower Jumps Into The Los Angeles Unconference

March 29, 2017 by Dan Maloney 1 Comment

When I was asked to cover the Unconference in Los Angeles last week, I have to admit that I was a more than a little uncomfortable with the idea. I’m not big on traveling, and the idea of meeting a lot of folks was a little intimidating. Surely meeting Hackaday readers in person would be like walking into a real-life version of the comments section of a particularly controversial post. Right?

I couldn’t have been more wrong.

The LA Unconference, held at the Supplyframe Design Lab in Pasadena, was a far more collegial and engaging conference than any I’ve been to in my professional life. I couldn’t have asked for a better group to share the afternoon and evening with, and the quality of the talks was excellent. The Design Lab turned out to be a great space for the event — a large main room for the talks with plenty of little areas to break away for impromptu discussions and networking.

The Midwest RepRap Festival Spectacular

March 28, 2017 by Brian Benchoff 5 Comments

Every year, nestled between a swine auction and beef auction at the fairgrounds in Goshen, Indiana, the world’s greatest 3D-printing meetup happens. The Midwest RepRap Festival draws the greatest minds in 3D printing from around the world, with teams flying in from Prague, Oxford, and Hong Kong. This year was bigger than any other year. Over 1,000 people ventured forth into the sticks to attend this awesome festival dedicated to DIY printers.

What did we see this year? The PartDaddy, SeeMeCNC’s 18-foot-tall delta printer made an appearance. We saw a new extruder from E3D, and an announcement that Open Source filaments will soon be a reality. True color printing with a five filament CMYKW system is weird and cool. DIY resin printers using laser diodes and galvos are now a thing. An Easy Break Oven isn’t broken. Printers with an infinite build volume now exist, and it skirts around a MakerBot patent, too.

There was more to see at MRRF than a single weekend would allow. [Jason Kridner] from BeagleBone was there talking about the latest in fancy single-chip Linux computers. Hackerspaces were there talking about their coolest builds and doing the calculations necessary to strap model rocket engines to 3D printed rockets. A few local colleges sent teams out to talk about their efforts to bring additive manufacturing to their programs. YouTube personalities were there. Check out the rest of the goodies we saw below.

Next Weekend: The Vintage Computer Festival East

March 28, 2017 by Brian Benchoff 13 Comments

Next weekend is the Vintage Computer Festival East in Wall, New Jersey. We’re going, and you should be there too.

The VCF East is the largest gathering of retrocomputing aficionados on the east coast. It’s three days of talks, exhibits, a flea market, and a pow-wow of the greatest minds buried under obsolete technology. No VCF is complete without a few talks, and this year is shaping up to be great. Keynotes will include [Bjarne Stroustrup], designer / implementor / inventor of C++. Computer historian [Bill Degnan] will give a review of 40 years of ‘appliance computers’, and [Tom Perera], Ph.D. will be giving a talk on the Enigma machine.

The exhibits at VCF are always the star of the show, and this year is no different. Highlights include mechanical computers, the finest from Silicon Graphics, and a version of Unix published by Microsoft. The individual exhibits are always great; last year the world’s first digital camera made an appearance. If you’re in the area, this isn’t an event to miss. VCF is going down at InfoAge, a science center at the former Camp Evans — a military installation that is best described as, ‘DARPA before World War II’.

Hackaday is proud to once again sponsor VCF East. This has been going on for a couple of years now and our Art Director, [Joe Kim] has created some incredible art as part of the sponsorship. Click on the thumbnail of this year’s art to embiggen. The VCF West art from last year is a stunning take on the Macintosh and last year’s VCF East art reflected the retro hackathon we sponsored.

MRRF 17: A Working MakerBot Cupcake

March 27, 2017 by Brian Benchoff 27 Comments

The Midwest RepRap Festival is the best place to go if you want to see the latest in desktop 3D printing. This weekend, we saw full-color 3D printers, a printer with an infinite build volume, new extruders, a fantastic development in the pursuit of Open Source filament, and a whole bunch of D-bots. If you want the bleeding edge in 3D printing, you’re going to Goshen, Indiana.

Of course, it wasn’t always like this. In 2009, MakerBot released the Cupcake, a tiny printer that ushered in the era of democratized 3D printing. The Cupcake was a primitive machine, but it existed, it was open source, and it was cheap – under $500 if you bought it at the right time. This was the printer that brought customized plastic parts to the masses, and even today no hackerspace is complete without an unused Cupcake or Thing-O-Matic sitting in the corner.

The MakerBot Cupcake has not aged well. This should be expected for a technology that is advancing as quickly as 3D printing, but today it’s rare to see a working first generation MakerBot. Not only was the Cupcake limited by the technology available to hackers in 2009, there are some pretty poor design choices in these printers. There’s a reason that old plywood MakerBot in your hackerspace isn’t used anymore – it’s probably broken.

This year at MRRF, [Ryan Branch] of River City Labs brought out his space’s MakerBot Cupcake, serial number 1515 of 2,625 total Cupcakes ever made. He got his Cupcake to print a test cube. If you’re at all familiar with the Cupcake, yes, this is a hack. It’s a miracle these things ever worked in the first place.
