Piano rolls are the world’s longest-lasting recording medium, and its first digital one. They were mass-produced from 1896 to 2008, and you can still get some made today, although they’re a specialty item. The technology behind them, both on the player and the recorder side, is simply wonderful.
[lwalkera] sent us in this marvelous video (embedded below) that provides a late-80s peek inside the works of QRS Records, and the presenter seems to be loving every minute of it.
Player pianos are cool enough, with their “draw bar” pulling air through the holes in the paper roll as it goes by, and pneumatically activating the keys. But did you ever think of how the rolls are made?

There’s a new documentary series on Al Jazeera called Rebel Geeks that looks at the people who make the stuff everyone uses. The latest 25-minute part of the series is with [Massimo], chief of the arduino.cc camp. Upcoming episodes include Twitter co-creator [Evan Henshaw-Plath] and people in the Madrid government who are trying to build a direct democracy for the city on the Internet.
Despite being a WiFi device, the ESP8266 is surprisingly great at being an Internet of Thing. The only problem is the range. No worries; you can use the ESP as a WiFi repeater that will get you about 0.5km further for each additional repeater node. Power is of course required, but you can stuff everything inside a cell phone charger.
I’ve said it before and I’ll say it again: the most common use for the Raspberry Pi is a vintage console emulator. Now there’s a Kickstarter for a dedicated tabletop Raspi emulation case that actually looks good.
Pogo pins are the go-to solution for putting firmware on hundreds of boards. These tiny spring-loaded pins give you a programming rig that’s easy to attach and detach without any soldering whatsoever. [Tom] needed to program a few dozen boards in a short amount of time, didn’t have any pogo pins, and didn’t want to solder a header to each board. The solution? Pull the pins out of a female header. It works in a pinch, but you probably want a better solution for a more permanent setup.
Half of building a PCB is getting parts and pinouts right. [Josef] is working on a tool to at least semi-automate the importing of pinout tables from datasheets into KiCad. This is a very, very hard problem, and if it’s half right half the time, that’s a tremendous accomplishment.
Last summer, [Voja] wrote something for the blog on building enclosures from FR4. Over on Hackaday.io he’s working on a project, and it’s time for that project to get an enclosure. The results are amazing and leave us wondering why we don’t see this technique more often.
When it comes to manufacturing, no place in the world has the same kind of allure as the Pearl River Delta region of China. Within just an hour-long train ride, two vastly different cultures co-exist, each with its unique appeal that keeps attracting engineers, entrepreneurs, and hustlers alike. On the mainland side, cities like Shenzhen and Guangzhou bring the promise of cheap components, low-cost contract work, and the street cred of “having done the Shenzhen thing.” And on the island, the capitalist utopia called Hong Kong glows with all of its high finance and stories of lavish expat lifestyles.
As the “new” China evolves, it seems like it’s exactly the convergence of these two cultures that will bring the biggest change—and not just to the area but to the whole world. Still, understanding what exactly is going on and what the place is really all about remains a mystery to many. So, this June, we jumped on the bandwagon and headed east, trying to get our own feel for the whole thing.
Here’s what we came back with…

Check out this Pokemon Yellow cartridge for Super Nintendo. Wait, what? That is a Game Boy game! Well there is a Super Gameboy cartridge that lets you play them on SNES. This mashes the guts of the two into a custom-decorated SNES cart. Now if you’re more interested in the guts of that Super Game Boy cartridge you’ll want to check out this classic hack which dumped the ROM from it. [Thanks Nick]
Here are a couple of interesting things from our friends over at Adafruit. First off, they have a high-res gallery of the Raspberry Pi compute module and carrier boards which we heard about earlier in the week. Also, the latest Collin’s Lab has a great video on soldering. We especially appreciated the discussion of soldering iron tips and their effect on heat transfer.
[Marius] got tired of the static shock from the office coat rack. You know, like the scene straight out of Office Space? But he didn’t disassemble the infrastructure to solve the issue. Instead he connected it directly to ground. Just make sure you stick the wire in the correct hole!
It’s as if Hackaday is on a quest for the most perfect DIY cyclonic separator. Here’s the latest offering which you can cut out from sheet stock by hand. It’s the alternative for those of us without access to a 3D printer.
If you think it’s too difficult to build what we refer to as a Daft Punk table you need to check out what [Dan] pulled off. He proves that your LED matrix coffee table project doesn’t have to take up a ton of time or cost an exorbitant amount of cash.
We should have mentioned this to you before the weekend so you’d have something to watch: you can now download BBS: The Documentary from the Internet Archive. We’ve watched the entire thing and it’s fantastic. If you know what a dial-up modem handshake sounds like, you’re going to be awash in nostalgia. If you don’t know the delight of those sounds you need to watch this and see how things used to be back in the day when connecting your computer to a network definitely wasn’t what the cool kids were doing. [Thanks Larry]
This isn’t our usual faire, it’s a really cool documentary on a hacker. [JJ Dasher] is a tinkerer from Taylorsville, Utah — and this is his story.
Like many mechanical hackers, he got his start taking apart engines with his dad who owned a motorcycle repair shop at the time. The cover photo above is of his micro-bike project, which can get him going quite fast! He’s also built quite a few tesla coils, and loves picking up things from thrift stores to hack. He’s got a kid now which takes up a lot of his time, but he jokes that his son is just his next big project waiting to be finished.
We’ve actually featured [JJ’s] projects quite a few times before. He brought us the Doombox (handheld Doom-only computer), the awesome brute force GPS PIN cracker, and in the spirit of halloween one of our favorites: a tesla coil that delivers shocking candy!
Stick around after the break to watch the well-filmed documentary — don’t worry, it’s only 8 minutes long!

Let’s face it, we all love DEFCON. Even if you’ve never been there before, we think it would be a huge struggle to find a reader who hadn’t been enchanted by at least one of the many hacks and talks that come out of the conference every year. We’ll prove it to you in a second, but first let’s get to the business at hand. Internet historian and all around good-guy [Jason Scott] has set his documentarian skills on DEFCON and just published a nearly twenty minute preview of the film which will leave you with more questions than answers (that’s the point of a teaser, right?). He’s not new to this kind of work. We loved his film BBS: The Documentary and can’t wait to see what he’s managed to do when this is released in the new year.
Oh yeah… we were going to prove a point. Some things that came out of the yearly hacker conference which you probably drooled over after the fact include:
This is just a sliver of what this event offers. Should be fun to see all the stuff [Jason] got into that we never even knew about.
Remember when you used to have to dial into a Bulletin Board System to connect with others through computers? How about those fond memories of phone phreaking? If you find that the details are fading in your mind you’ll be happy to know that [Jason Scott] is making sure they’ll never be forgotten. And now he’s landed a new job that will make this mission even easier.
We’re most familiar with [Jason’s] film, BBS: The Documentary. This five-hour epic traverses the oft-forgotten world of the BBS. It pays attention to things like the formation of ASCII art groups, the elite control of the Sysop before the Internet decentralized access to information, and quirky technological limitations like what happened as FIDOnet ran out of addresses for new nodes.
In short, [Jason Scott] is a technological historian. He gives speeches, makes movies, and finds information stashes that history shouldn’t forget. He’s done this outside the tradition of finding a Professorship or Curator position for a major institution. Instead he asked for sabbatical funding through Kickstart, and now he’s found his way to a position that seems like it’s made just for him; Archivist for the Internet Archive. Go get ’em [Jason].
