Retrocomputing For The Masses Hack Chat

Join us on Wednesday 29 May 2019 at noon Pacific for the Retrocomputing for the Masses Hack Chat!

Of the early crop of personal computers that made their way to market before IBM and Apple came to dominate it, few machines achieved the iconic status that the Sinclair ZX80 did.

Perhaps it was its unusual and appealing design style, or maybe it had more to do with its affordability. Regardless, [Sir Clive]’s little machine sold north of 100,000 units and earned a place in both computing history and the hearts of early adopters.

Spencer Owen is one who still holds a torch for the ZX80, so much so that in 2013, he hatched a seemingly wacky idea to make his own. A breadboard prototype of the Z80 machine slowly came to life over Christmas 2013, one thing led to another, and the “RC2014” was born.

The RC2014 proved popular enough to sell on Tindie, and Spencer is now following his dream as a retrocomputing mogul and working on RC2014 full time. He’ll be joining us to discuss the RC2014, how it came to be, and how selling computing nostalgia can be more than just a dream.

This Saturday: Meetup With Hackaday, Tindie, And Kickstarter

If you’re near San Francisco this weekend, this is what you should be doing. It’s The 6th Annual Hackaday x Tindie MFBA Meetup w/ Kickstarter.

Come hang out with the hardware hackers and bring along a project of your own to get the conversation going. We’re excited to move to a new, larger venue this year. All the good of the past five years will come along with us, plus many benefits of exclusively booking out an entire venue. You can catch up with people who have been on their feet all day running booths — and usually see the stuff they can’t show you at the Faire. The crew from Hackaday, Tindie, and Kickstarter will be on hand. And you’ll get a glimpse of a lot of the cool people and projects you’ve admired on the pages of Hackaday over the years. It’s fun, you should go!

First beer is on us if you RSVP using the link at the top of this article. But we’re mainly publishing this today to show off the poster art. Deposit your adoration for this exquisite illustration in the comments below.

Amazing Art by Joe Kim

We love all of the original art that Joe Kim creates for Hackaday articles. It’s impossible to look at his poster for this event and be anything but overjoyed. Here’s a link to the full size image, but be warned that the file is 14.4 MB

6th Annual Hackaday X Tindie MFBA Meetup With A New, Larger Venue

We want to hang out with you at Maker Faire Bay Area! Put our after-hours meetup on your schedule with a Sharpie, because the 6th Annual Hackaday x Tindie MFBA Meetup w/ Kickstarter will be bigger and better than ever with a new venue that has plenty of room for everyone!

The hacker crowd descends upon San Mateo weekend after next to show off a year of creations at Maker Faire. On Saturday, May 18th, the Faire will close for the evening as our meetup heats up. Bring along some hardware to show off and get the conversation started. Whether you’re attending the Faire or staffing a booth all day, this is the perfect way to unwind.

New Place with More Space!

Every year we’ve been packed to the gills and it’s time to make room for more people. This year Hackaday and Tindie have teamed up with Kickstarter to rent out the entire B Street Station in San Mateo. It’s close by and has plenty of room to hang out with friends new and old. We’ll provide light food and the first drink is on us! Please RSVP so we know how many people to expect, and like we said, grab a project to bring along! This event is open to all who are 21 years of age or older.

Begin Your Weekend with HDDG on Thursday

Start the weekend off right with the HDDG meetup on Thursday night. In keeping with tradition, this special Maker Faire edition of the Hardware Developer’s Didactic Galactic is happen at the San Francisco Supplyframe office on May 16th. You’ll find a ton of people from out of town on hand to enjoy talks ranging from non-rectangular phone design and mitigating ESD in wearables, to getting your projects funded with PR stunts. Speakers include Christina Cyr, Mary West, and Mic Black.

Clock Mod Brings Super Game Boy To Competitive Arena

For one time small window between 1994 and 1998, you could play Game Boy games in color with a Super Game Boy. This was a cartridge that plugged into a Super Nintendo, and using proprietary Lock-On™ technology, you could play Game Boy games on the big screen. Inside the Super Game Boy was the guts of a real Game Boy. This was, and still is, the best way to experience everything from Kirby’s Dream Land or the Pokemon of Kanto.

Unfortunately, the Super Game Boy doesn’t exactly replicate the Game Boy experience. The crystal in the Super Game Boy means that games and sound run between 2 and 4% faster. The Super Game Boy is out for competitive speed running, and if you’re using Little Sound DJ, you’ll be out of tune with the rest of the band. The Super Game Boy doesn’t have link cable support, either.

Now, [qwertymodo] over on Tindie has the solution to the faster Super Game Boy. It’s a clock mod, but it’s not just swapping a crystal. This is a board that solders to existing pads, and still allows you to access the speed up and slow down functions available from the Commander controller from Hori. It’s a slightly impressive bit of PCB art, and certainly something that deserves notice.

This mod fixes the 2-4% speedup of the Super Game Boy, but then there’s still one feature missing: the link cable. Well, hold on to your butts, because there’s a mod for this one too. The Super Game Boy Link Port is a small little breakout board that requires fly wires to the main chip in the Super Game Boy. The installation isn’t quite as clean as the crystal hack, but if you’re fixing the clock, you might as well add the link cable port while you’re in there.

[qwertymodo] has a comparison test of the Super Game Boy running Pokemon Red, and this thing is dead on. It runs at exactly the same speed as an original Game Boy, only in color, on a TV. You can check that out below.

Nixie Power Supply Shows Ins And Out Of Offshore Manufacturing

[Tony] built a high-efficiency power supply for Nixie tube projects. But that’s not what this post is about, really.

As you read through [Tony]’s extremely detailed post on Hackaday.io, you’ll be reading through an object lesson in electronic design that covers the entire process, from the initial concept – a really nice, reliable 170 V power supply for Nixie tubes – right through to getting the board manufactured and setting up a Tindie store to sell them.

[Tony] saw the need for a solid, well-made high-voltage supply, so it delved into data sheets and found a design that would work – as he points out, no need to reinvent the wheel. He built and tested a prototype, made a few tweaks, then took PCBWay up on their offer to stuff 10 boards for a mere $88. There were some gotchas to work around, but he got enough units to test before deciding to ramp up to production.

Things got interesting there; ordering full reels of parts like flyback transformers turned out to be really important and not that easy, and the ongoing trade war between China and the US resulted in unexpected cost increases. But FedEx snafus notwithstanding, the process of getting a 200-unit production run built and shipped seemed remarkably easy. [Tony] even details his pricing and marketing strategy for the boards, which are available on Tindie and eBay.

We learned a ton from this project, not least being how hard it is for the little guy to make a buck in this space. And still, [Tony]’s excellent documentation makes the process seem approachable enough to be attractive, if only we had a decent idea for a widget.

Hackaday Links: March 31, 2019

You can now make flexible circuit boards of unlimited length. Trackwise was contracted out for making a wiring harness for the wing of a UAV and managed to ship a 26 meter long flexible printed circuit board. This is an interesting application of the technology — UAVs are very weight sensitive and wiring harnesses are heavy. Wings are straight, but they flex, and you need wires going from tip to tip. Flex circuits do all of this well, but first you need a technology that allows you to manufacture circuits that are as long as a wing. This is apparently something called ‘reel-to-reel’ technology, or some variant of continuous production. Either way, it’s cool, and we’re wondering what else this kind of circuit enables.

You may have noticed a few odd-shaped buildings going up in the last few years. These are buildings designed for indoor skydiving. Two went up around DC in the last year or so. What if you didn’t need a building? What if you could make an outdoor, vertical wind tunnel? Here you go, it’s the Aerodium Peryton.

KiCon, the first and largest gathering of hardware developers using KiCad, is happening April 26th in Chicago.

If KiCad isn’t your thing, PyCon is in Cleveland May 1-9. It couldn’t come at a better time: after losing LeBron, the Cleveland economy has plummeted 90%. Cleveland needs an industry now, and tech conferences are where it’s at. Go Browns.

For one reason or another, a few tech blogs wrote about a product on Tindie last week. It’s the SnapOnAir Raspberry Pi Zero PCB. This turns a Raspberry Pi Zero into a tiny, battery-powered handheld computer with a keyboard and display. This is just a PCB, and you’ll need to bring your own switches, display, and other various modules, but it is a compact device and if you need a small, handheld Linux thing, this is a pretty good solution.

Oh noes April Fools is tomorrow, which means the Internet will be terrible. Tip ‘o the hat to Redbox, though: they were the only one that sent out a press release to their waste of electrons by last Friday.

 

From Software To Tindie Hack Chat With Brian Lough

Join us Wednesday at noon Pacific time for the From Software to Tindie Hack Chat!

Brian Lough has followed a roundabout but probably not unusual route to the hardware hacking scene. Educated in Electronic and Computer Engineering, Brian is a software developer by trade who became enamored of Arduino development when the ESP8266 hit the market. He realized the microcontrollers such as these offered incredible capabilities on the cheap, and the bug bit him.

Since then, Brian has fully embraced the hardware hacking way, going so far as to live stream complete builds in a sort of collaborative “hack-along” with his viewers. He’s also turned a few of his builds into legitimate products, selling them on his Tindie store and even going so far as to automate testing before shipping to catch errors and improve quality.

Please join us for this Hack Chat, where we’ll discuss:

  • How software hacking leads to hardware hacking;
  • The creative process and how live streaming helps or hinders it;
  • The implications of going from project to product; and
  • What sorts of new projects might we see soon?
