Like modular synths? Sure you do, and you need another hole to throw money into! For the last few months, Supplyframe has been hosting synthesizer and electronic music meetups in San Francisco. This week, the HDDG/Piqued meetup will have a great talk with the creator of VCV Rack. VCV Rack is an Open Source, virtual, modular synthesizer — basically a bunch of Eurorack modules inside a computer and it costs a whole lot less. The talk is this Thursday evening in SF. You should come!

The W600 is a new module (you can get it from Seeed, although it’s produced by Winner Micro in various formats) that is basically an ESP32, except it uses an ARM Cortex-M3 instead of a Tensilica core. [ultratechie] recently got their hands on one of these modules and got started with MicroPython. This seems like a capable module and it’s only three dollars, but will that be enough to catch up to the ESP32?

Purple gorilla enters art gallery. At the Het Nieuwe Instituut in Rotterdam there is a new exhibit featuring the, ‘destructive beauty of the computer virus’. The curators are detailing the historical progress of the computer virus from innocent DOS viruses to Melissa to Stuxnet and ransomware.

USB C has been around for a while, but 2019 is the year everything started to become USB C. Case in point: the Raspberry Pi 4. The only problem is that the Raspberry Pi Foundation messed up their implementation of USB C. Not a problem, because here’s how you design a USB C power sink. Basically, you give each CC line its own resistor. Don’t even think about it, just copy the USB C spec. You don’t know more about USB C than the people who designed it, and you’re not really saving a ton of money by deleting one resistor. Just copy the spec.

Teardown 2019: A Festival Of Hacking, Art, And FPGAs

July 3, 2019 by Helen Leigh 7 Comments

As hackers approached the dramatic stone entrance of Portland’s Pacific Northwest College of Arts, a group of acolytes belonging to The Church of Robotron beckoned them over, inviting them to attempt to earn the title of Mutant Saviour. The church uses hazardous environments, religious indoctrination, a 1980s arcade game and some seriously funny low tech hacks to test your abilities to save humanity. This offbeat welcome was a pretty good way to set the tone for Teardown 2019: an annual Crowd Supply event for engineers and artists who love hardware. Teardown is halfway between a conference and a party, with plenty of weird adventures to be had over the course of the weekend. Praise the Mutant! Embrace Futility! Rejoice in Error!

For those of us who failed to become the Mutant Saviour, there were plenty of consolation prizes. Kate Temkin and Mikaela Szekely’s talk on accessible USB tools was spectacular, and I loved following Sophi Kravitz’s journey as she made a remote-controlled blimp. Upstairs in the demo room, we had great fun playing with a pneumatic donut sprinkle pick and place machine from tinkrmind and Russell Senior’s hacked IBM daisywheel typewriter that prints ASCII art and runs a text-based Star Trek adventure game.

It wouldn’t be much of a hardware party if the end of the talks, demos and workshops meant the end of each day’s activities, but the Teardown team organised dinner and an afterparty in a different locations every night: Portland’s hackerspace ^H PDX, the swishy AutoDesk offices, and the vintage arcade game bar Ground Kontrol. There also was a raucous and hotly-contested scavenger hunt across the city, with codes to crack, locks to pick and bartenders to sweet talk into giving you the next clue (tip: tip).

Join me below for my favorite highlights of this three day (and night) festival.

Forty Four Hackers And A Hatch: Progress Egress Takes Off

July 3, 2019 by Dan Maloney 14 Comments

The 50th anniversary of the first Moon landing is rapidly approaching, and uber space-nerd Adam Savage is in the thick of the celebration of all the amazing feats of engineering that made humanity’s first steps out of the cradle possible. And in a grand and very hacker-friendly style, we might add, as his Project Egress aims to build a full-scale replica of the Apollo 11 Command Module Columbia’s hatch.

Mary Sherman Morgan, Rocket Fuel Mixologist

In the fall of 1957, it seemed as though the United States’ space program would never get off the ground. The USSR had launched Sputnik in October, and this cemented their place in history as the first nation in space. If that weren’t bad enough, they put Sputnik 2 into orbit a month later.

By Christmas, things looked even worse. The US had twice tried to launch Navy-designed Vanguard rockets, and both were spectacular failures. It was time to use their ace in the hole: the Redstone rocket, a direct descendant of the V-2s designed during WWII. The only problem was the propellant. It would never get the payload into orbit as-is.

The US Army awarded a contract to North American Aviation (NAA) to find a propellant that would do the job. But there was a catch: it was too late to make any changes to the engine’s design, so they had to work with big limitations. Oh, and the Army needed it two days before yesterday.

The Army sent a Colonel to NAA to deliver the contract, and to personally insist that they put their very best man on the job. And they did. What the Army didn’t count on was that NAA’s best man was actually a woman with no college degree.

New Contest: Beautiful Hardware

July 2, 2019 by Mike Szczys 13 Comments

We all have awesome hardware projects to show off. Great photos of them are how you unlock the excitement others see in your work. Whether you’re using a DSLR or the camera in your smartphone, it’s not difficult to capture an amazing picture of the project you pour so much effort into. We want you to unleash your photography skills for the Beautiful Hardware contest. Show us your epic hardware photos and win prizes.

The Skeleton Watch by Mile is a great example of superb photography. Excellent framing, focus, and color make it great.

The only real barrier between us and superb hardware photos is having an eye for framing your shots, and a few simple tricks to get everything else right. Think about good lighting, shooting with an interesting background, framing off to the side and at an angle (as just one example) for more interest, and spending a few moments with an image editor to complement what the camera captured. With this contest, we want you to take those tricks for a spin on your own workbench.

Lee Wilkins put together a simple guide to get you going with spectacular hardware photography. From the basics of photography and the tricks used for making product hype photos, to capturing great images of LEDs and getting the colors just right, this is a comprehensive quickstart. There’s even a collection of great examples to strive for.

There are three top prizes of $100 cash waiting for you. Just start a new project on Hackaday.io and upload the finest photos you can take of some fun hardware. In the left sidebar of that project use the “Submit project to…” menu to enter it in the Beautiful Hardware contest.

Ask Hackaday: How Can You Build For A Ten Millennia Lifespan?

July 1, 2019 by Al Williams 97 Comments

There’s been a lot of news lately about the Long Now Foundation and Jeff Bezos spending $42 million or so on a giant mechanical clock that is supposed to run for 10,000 years. We aren’t sure we really agree that it is truly a 10,000 year clock because it draws energy — in part — from people visiting it. As far as we can tell, inventor Danny Hills has made the clock to hoard energy from several sources and occasionally chime when it has enough energy, so we aren’t sure how it truly sustains itself. However, it did lead us to an interesting question: how could you design something that really worked for 10,000 years?

In our continuing series of, ‘point and laugh at this guy’, I present a Kickstarter for the, “World’s First Patented Unhackable Computer Ever”. It’s also a real web site and there’s even a patent (US 10,061,923, not showing up on Google Patents for some reason), and a real product: you can get an unhackable laptop, and you can get it in either space gray or gold finish. This gets fun when you actually dig into the patent; it appears this guy invented protected memory, with one section of memory dedicated to the OS, and another dedicated to the browser. This is a valid, live patent, by the way.

The 2019 New York Maker Faire is off. Yeah, it says it’s still going to happen on the website, but trust me, it’s off, and you can call the New York Hall of Science to confirm that for yourself. Maker Media died recently, and there will be no more ‘Flagship’ Maker Faires. That doesn’t mean the ‘mini’ and ‘featured’ Maker Faires are dead, though: the ‘Maker Faire’ trademark is simply licensed out to those organizers. In the next few weeks, there is going to be a (mini) Maker Faire in Coeur d’Alene, Idaho, Gilroy, California, Edmonton, Alberta, Kingsport Tennessee, and a big ‘ol one in Detroit. This raises an interesting question: where is the money for the licensing going? I’m sure some Mini Maker Faire organizers are reading this; have your checks been cashed? What is the communication with Maker Media like?

Just because you can, doesn’t mean you should. It’s valuable words of wisdom like that and can apply to many things. Commenting on blog posts, for example. Yes, you can throw sticks at a wasp’s nest, that doesn’t mean you should. Yes, you can 3D print Heely adapters for your shoes, but it doesn’t mean you should. It does look dope, though and you’re automatically a thousand times cooler than everyone else.

The C64 Mini is a pocket-sized Linux device with an HDMI port meant to play C64 games. There were high hopes when the C64 Mini was announced, but it turned out the keyboard isn’t actually a mini keyboard. Now someone had the good sense to combine one of these ‘smartphone chips running an emulator in a retro case’ products with a full-sized keyboard. The C64 will be around by Christmas, and yeah, it has a full working keyboard.
