F.A.T. GOLD San Francisco: May 21-31

April 19, 2015 by Mike Szczys 2 Comments

Two of the ideas we keep at our core here at Hackaday: the free and open exchange of information and ideas; and “why” is the wrong question. These concepts are fully in line with the F.A.T. Lab. The Free Art and Technology Lab lives at the intersection of Open Source and Pop Culture and they’re inviting you to jump into the pool of awesome by joining them for the F.A.T. Gold Show in San Francisco May 21-31.

If you’re unfamiliar with the group, take a look at the video after the break and you’ll easily confirm that you need to check this out. We’ve enjoyed the work of F.A.T. Lab members for years now. [Brian] pointed out part of the importance of the “Open” aspect the group in this post on universal connectors for popular toy blocks. We also covered their collaboration on EyeWriter which shows how to build IR eye tracking for the disabled. The group hosts the Graffiti Research Labs (also a collaborator on EyeWriter); we built their Laser Graffiti project as part of a live Hackaday event in January of last year thanks to the open source code they published.

What will you see at this year’s show? The best work the group has to offer from the last eight years plus some debut exhibits. We wish we could be there but we’re planning to be in LA that weekend for the LayerOne conference.

VCF East X: The Not Trashy Eighty

April 18, 2015 by Brian Benchoff 7 Comments

The lowly TRS-80 doesn’t get much love in most circles; it’s constantly overshadowed by the popularity of the Apple II or computers that had graphics that weren’t terrible. For [Mike Loewen]’s VCF exhibit, he’s turning his TRS-80 into something good with SD card disk drives and custom graphics adapters.

The -80 in question is a Model 4, the fancy all-in-one version that could run CP/M. The disk drives in this computer were replaced with half-height 5 1/4″ drives, the 200ns RAM was replaced with 100ns RAM and modified to get rid of the wait states, and a hard drive is emulated on a SD card adapter thanks to an add-on from [Ian Mavric].

[Ian] is somewhat prolific in the world of TRS-80s; he reverse engineered the original hi-res graphics board and reimplemented it with video RAM chips of a more modern vintage.

VCF East X: Virtual Reality With PETSCII

April 18, 2015 by Brian Benchoff 3 Comments

What would happen if Oculus-quality virtual reality was created in the 80s on the Commodore PET? [Michael Hill] knows, because he created a stereoscopic video headset using a PET.

This build is an extension of [Michael]’s exhibit last year at VCF East where he displayed a video feed with PETSCII. Yes, that means displaying video with characters, not pixels.

This year, he’s doubling the number of screens, and sending everything to two iPhones in a Google Cardboard-like VR headset. Apart from the optics, the setup is pretty simple: cameras get image data, it’s sent over to a PET, and a stream of characters are sent back.

It’s impossible to film, and using it is interesting, to say the least. Video below.

VCF East X: The Quarternet Steering Committee

April 18, 2015 by Brian Benchoff 17 Comments

Today was the first day of the Vintage Computer Festival East X. As is the tradition, the first day was packed with talks and classes about various retrocomputing ephemera, with this year featuring a great talk from [David Riley] about 8-bit computer music, a class on system architecture from our own [Bil Herd] (video coming soon), and a talk about vintage teletypes. One of these talks was about creating new hardware: [Jim Brain]’s steering committee on a networking solution for vintage microcontrollers. It’s called Quarternet: a two-bit solution for an eight bit world.

While minicomputers are easily networkable, designed around multi-user operating systems, and have the hardware for a lot of networking hardware, 8-bit micros are the exact opposite. That doesn’t mean 8-bitters don’t have networking; you can get an Ethernet cart for a C64, and just about everything can connect to a BBS. [Jim]’s talk was about whittling down the use cases for the Quarternet to something that could be implemented easily, but still give the most capability.

During the talk, the audience settled on using a serial connection from the micro to the outside world; this makes sense, as everything has a serial port. A ‘lightweight API’ was suggested to take up the software side of the problem, but there wasn’t much agreement over what that API would actually do.

[Jim]’s idea is for a box that plugs into the serial port of any old microcomputer and would connect to the Internet somehow. Ethernet, WiFi, or even a modem isn’t out of the question here. That takes care of connecting to the Internet, but there’s also the question of the cooler side of networking – network drives, file sharing, and the like.

For this, [Jim] is imagining a box with a serial port on one end, and a network port on the other. In the middle would be a cartridge slot for any hardware imaginable. If you want to plug in an Apple II disk drive, just insert the right cartridge and you’re good to go. If you need network access to a Commodore 1541 drive, just insert another cartridge, and it’ll just work.

It’s an interesting idea, but [Jim] is really interested in getting even more feedback for a networking system for old microcomputers. If you have any ideas, leave a note for him in the comments.

RadioShack Demise Could Signal The Rise Of Mom-and-Pop

April 16, 2015 by Mike Szczys 103 Comments

No matter how you feel about RadioShack, for many hackers it was the one place that components could be sourced locally. Upon hearing that the stores are being shuttered (at least for those seeking non-cellphone items) we wondered if someone would rise to meet the maker market. The answer may actually be mom-and-pops — independent stores owned by people passionate about hacking and making.

At SXSW Create in March the Hackaday booth was right next door one such establishment. [Martin Bogomolni] is hard at work launching his brick and mortar store called Tinker & Twist. In the video below he speaks briefly about the concept of the store, which focuses on curating the best products and tools available and stocking them locally.

The store will be located in a shopping mall in Austin, Texas. But it takes about 100 days launch a storefront considering the permits and build-out. [Martin] decided to take the store to the hackers by exhibiting (and selling products) at SXSW Create. How else would you do this than by building a store-front as your booth? The store’s sign was CNC routed from rigid foam, and combined with a set of columns and storefront window. We stopped by late on the last day of the event and they had been having a great weekend. What started as a very well stocked set of shelves looked nearly bare.

Tinker & Twist is just the most recent in a growing trend of standalone stores focusing on hackers and makers. Our friends at Deezmaker in Pasadena, CA gave us tour last year. They’ve married the concepts of hackerspace, small-run manufacturer (in the form of their 3D printers), and retail store all-in-one. These types of examples make us quite happy — it’s been years since RadioShack was tightly focused on those actually building things. We hope to see more stores like Tinker & Twist up and running to support and enhance hacker communities everywhere.

Retro Edition: VCF East X This Weekend

April 15, 2015 by Brian Benchoff 13 Comments

It’s mid-April and time once again for the Vintage Computer Festival East X. The X means 10. It’s a three-day weekend full of interesting people, cool tech, and computers you’ve only heard about. We’ll be there all three days, and if you’re in New York or are unable to pump your own gas (Oregon excluded), it’s a great way to spend the weekend.

The sessions for this Friday will include everything from chiptunes to retr0bright to emulating vintage computers on FPGAs. Sessions of note include our own [Bil Herd] giving a talk on system architecture. Think of this as a bunch of engineers in a room with a whiteboard. How could you not have fun with that. There will also be the first meeting of the Quarternet committee, headed up by [Jim Brain]. This session will be a discussion of implementing a vintage networking protocol across different models and different brands of vintage computers. Confused? It’s a, “two-bit solution for an eight-bit world.” That’s all we know, and I’m pretty sure that’s all anyone knows. It will be interesting.

Saturday and Sunday will feature an incredible number of exhibits that includes everything from Atari 8-bits, Hollerith cards, mainframes, an amateur radio station (KC1CKV) and somehow a Fairlight CMI. Since this is the 50th anniversary of the PDP-8, there will be a few of these ancient machines on display. A freshly restored Straight-8 will be up and working, as will an incredible emulation from hackaday.io.

Just because there are exhibits doesn’t mean the talks end on Friday. On Saturday the guest speaker will be [Brian Kernighan], the guy who literally wrote the book on C. Sunday will feature [Bob Frankston], co-developer of VisiCalc. There will be very important people here all weekend.

Even if vintage computers aren’t your thing, there’s still plenty of stuff to see at the venue. The InfoAge science center has technological curiosities stretching back a century, and recently they’ve rehabbed an old satellite dish and turned it into a radio telescope. Registration happens here, and if the last few paragraphs haven’t sold you on the event, you can check out [The Guru Meditation]’s VCF preview video below. We will, of course, be posting a lot of stuff from the event.

Hackaday Part Of TechCrunch NY Hackathon

April 13, 2015 by Mike Szczys 10 Comments

The Hackaday Prize Worldwide is coming to New York! Hackaday is adding a hardware-centric twist to the TechCrunch Disrupt in May. They’re kicking off the conference with a weekend hackathon which traditionally has been a software event. This year Hackaday is partnering with TC to make a change. If you’re a software-only sort of person, grabbing a ticket to the event is extremely tough. But those Hackaday community members who want to prove they can make electrons do their bidding still have hope; Hackaday can get you in!

Twenty Hours of Hardware

Show up at 12:30pm on Saturday, May 2nd. By 9:30am the next morning you must have a working piece of hardware having been totally built on-site. Starting at 11am on Sunday you have 60-seconds to show off your build. We’re not kidding around when we say the judging criteria for this hackathon is “Awesomeness”. TC is putting up $5,000 to the winning team. Obviously someone who hangs out around Hackaday should be the winner here so go sign up!

Ticket Registration is a Hack:

TC hackathon tickets are released in shifts and gobbled up immediately, but because you are a friend of Hackaday we’ll can get you in for some epic hardware hacking. Even signing up is a bit of hack but here’s how:

Follow this link which includes a promo code to get a Hackers – Friends of TC ticket
Form/Find a team (up to 5 people) in advance through ChallengePost or you may do so onsite. You’ll notice the tags are software-related so put in “other” and add “hardware” and specific tags you can think of.

The Hardware

We’ll be bringing the basics: lots of dev boards, sensor breakout boards, and tools you need to hook them together. We’ll be posting information about the items we are bringing on our Hackaday Prize Worldwide: New York City page. Make sure you check in for updates so that you can familiarize yourself with what we’ll have on-hand. It is highly recommended that you set up any IDE or other dev tools before arriving at the event.
