2017’s VCF West is Another Beloved Trip Down Memory Lane

This past weekend, another smashing round of the Vintage Computer Festival was held at the Computer History Museum in Mountainview. As always, VCF West gathers the sages and lords of vintage computers onto a common ground to talk old-school hardware. It also draws in a collection of unique artifacts, many of which either still work, have been brought back to life, or have otherwise been reincarnated through a modern means. [Bil Herd] and I dropped in to join the crowd, and I snagged a few pics of some new faces and pieces that have been added to the experience since last year.

[Foone’s] Digital Media Archiving

Up first on our bucket list was [Foone], a librarian of digital media archiving. Outside of VCF, he runs a digital media backup gig to help folks backup their niche, often-failing, disk formats into something more modern. His drive for doing this backup features a special “reread” capability, where the file is actually reread dozens of time to validate that the right information was pulled from it.

Differential Analyzer Cranks out Math like a Champ at VCF 2016

Here at VCF, we stumbled across a gigantic contraption that spanned several tables. Rube Goldberg machine this was not. Instead, this device actually does something useful! [Tim Robinson’s] differential analyzer can solve differential equations through several stages of mechanical integrators. The result is a pen-plot graph of the solution to the input equation, input by displacing a rod as a function of time.

Differential analyzers have been around for over a century. [Tim’s] claim to fame is that this particular DA is constructed entirely from Meccano-branded parts. We’re thrilled to see Meccano, over 100 years old at this point, continue to find new uses outside the toy box.

The Torque Amplifier

The differential analyzer is riddled with mechanisms that are bound to swing some heads for a double-take. Since the input shaft that transmits the input function f(x), has very little friction, the result can only be carried through the remainder of the machine with some means of torque amplification. To do so, [Tim], and most other DA designers implement a torque analyzer. For [Tim], though, this feat proved to be more difficult (and more triumphant) than other solutions, since he’s using a set of parts that are entirely from Meccano. In fact, this feature took [Tim] through about 20 iterations before he was finally satisfied.

VCF West continues to run through the end of the weekend at the Computer History Museum in Mountain View, CA. If you haven’t already packed your bags for DEF CON, stop by for a few more bewildering brain teasers.

Join Us at Vintage Computer Festival West This Weekend

VCF West is happening this Saturday and Sunday at the Computer History Museum in Mountain View, CA. This on of our favorite events; a celebration of the hardware that paved the way for our modern world. VCF attracts an impressive amount of rare and interesting computers and other technology items. That hardware doesn’t make it to the festival on its own. The people at VCF — exhibitors, speakers, attendees, etc — are themselves an incredible collection of stories from salvage and restoration to the inside story on the teams that made the computers in the first place.  Check out some of Brian Benchoff’s coverage of VCF East earlier this year.

VCF_coverI ran into Vintage Computer Federation President Evan Koblentz ten days ago and he shared an interesting anecdote I think you’ll enjoy. Bil Herd was a featured speaker at VCF East a few years back. He was the Senior Design Engineer behind the Commodore C128 — obviously a fascinating person to headline the event. The year after Bil spoke at the festival, Evan as surprised to run into him wandering around the event again. Bil didn’t just want to speak, he wanted to see all the cool stuff and has attended, spoken, and conducted workshops at several of the festivals since.

Who will show up this year is anyone’s guess. But we know this event is incredible and you will be amazed at who you run into. It is important to recognize where our technology comes from, to celebrate those who made it happen, and to encourage young people to start on the path to becoming a computer engineering wizard. For all of these reasons we are happy to be sponsoring VCF West. On the inside cover of every festival program you’ll find this epic art by our Illustrator, Joe Kim. You can also click the image on the right to embiggen.

Joshua Vasquez will on hand for Hackaday at VCF West. He’s looking for the best bits to feature on our front page. If you want get a hold of him to show off your wares, or to grab some excellent Hackaday stickers, hit him up on Hackaday.io.

Hackaday Links: July 24, 2016

Right now HOPE is dying down, and most of the Hackaday crew will be filtering out of NYC. It was a great weekend. The first weekend in August will be even better. We’re going to DEF CON, we’ll have people at VCF West, and a contingent at EMF Camp. If you’re going to EMF Camp, drop a line here. There will be Hackaday peeps wandering around a field in England, so if you see someone flying the Hackaday or Tindie flag, stop and say hi.

Raspberry Pi’s stuffed into things? Not all of them are terrible. The Apple Extended keyboard is possibly the best keyboard Apple ever produced. It’s mechanical (Alps), the layout is almost completely modern, and they’re actually cheap for something that compares well to a Model M. There’s also enough space inside the plastic to fit a Pi and still have enough room left over for holes for the Ethernet and USB ports. [ezrahilyer] plopped a Pi in this old keyboard, and the results look great. Thanks [Burkistana] for sending this one in.

We’ve been chronicling [Arsenijs] Raspberry Pi project for months now, but this is big news. The Raspberry Pi project has cracked 10k views on Hackaday.io, and is well on track to be the most popular project of all time, on any platform. Congrats, [Arsenijs]; it couldn’t happen to a better project.

A few months ago, [Sébastien] released SLAcer.js, a slicer for resin printers that works in the browser. You can’t test a slicer without a printer, so for the last few months, [Sébastien] has been building his own resin printer. He’s looking for beta testers. If you have experience with resin printers, this could be a very cool (and very cheap) build.

Anyone going to DEF CON? For reasons unknown to me, I’m arriving in Vegas at nine in the morning on Wednesday. This means I have a day to kill in Vegas. I was thinking about a Hackaday meetup at the grave of James T. Kirk on Veridian III. It’s about an hour north of Vegas in the Valley of Fire State Park. Yes, driving out to the middle of the desert in August is a great idea. If anyone likes this idea, leave a note in the comments and I’ll organize something.
