No, The Nintendo Leak Won’t Help Emulator Developers, And Here’s Why

If you haven’t heard from other websites yet, earlier this year a leak of various Nintendo intellectual properties surfaced on the Internet. This included prototype software dating back to the Game Boy, as well as Verilog files for systems up to the Nintendo 64, GameCube and Wii. This leak seems to have originated from a breach in the BroadOn servers, a small hardware company Nintendo had contracted to make, among other things, the China-only iQue Player.

So, that’s the gist of it out of the way, but what does it all mean? What is the iQue Player? Surely now that a company’s goodies are out in the open, enthusiasts can make use of it and improve their projects, right? Well, no. A lot of things prevent that, and there’s more than enough precedent for it that, to the emulation scene, this was just another Tuesday.

Masten Moon Rocket Has Landing Pad, Will Travel

Because of the architecture used for the Apollo missions, extended stays on the surface of the Moon weren’t possible. The spartan Lunar Module simply wasn’t large enough to support excursions of more than a few days in length, and even that would be pushing the edge of the envelope. But then the Apollo program was never intended to be anything more than a proof of concept, to demonstrate that humans could make a controlled landing on the Moon and return to Earth safely. It was always assumed that more detailed explorations would happen on later missions with more advanced equipment and spacecraft.

Now NASA hopes that’s finally going to happen in the 2020s as part of its Artemis program. These missions won’t just be sightseeing trips, the agency says they’re returning with the goal of building a sustainable infrastructure on and around our nearest celestial neighbor. With a space station in lunar orbit and a permanent outpost on the surface, personnel could be regularly shuttled between the Earth and Moon similar to how crew rotations are currently handled on the International Space Station.

Artemis lander concept

Naturally, there are quite a few technical challenges that need to be addressed before that can happen. A major one is finding ways to safely and accurately deliver multiple payloads to the lunar surface. Building a Moon outpost will be a lot harder if all of its principle modules land several kilometers away from each other, so NASA is partnering with commercial companies to develop crew and cargo vehicles that are capable of high precision landings.

But bringing them down accurately is only half the problem. The Apollo Lunar Module is by far the largest and heaviest object that humanity has ever landed on another celestial body, but it’s absolutely dwarfed by some of the vehicles and components that NASA is considering for the Artemis program. There’s a very real concern that the powerful rocket engines required to gracefully lower these massive craft to the lunar surface might kick up a dangerous cloud of high-velocity dust and debris. In extreme cases, the lander could even find itself touching down at the bottom of a freshly dug crater.

Of course, the logical solution is to build hardened landing pads around the Artemis Base Camp that can support these heavyweight vehicles. But that leads to something of a “Chicken and Egg” problem: how do you build a suitable landing pad if you can’t transport large amounts of material to the surface in the first place? There are a few different approaches being considered to solve this problem, but certainly one of the most interesting among them is the idea proposed by Masten Space Systems. Their experimental technique would allow a rocket engine to literally build its own landing pad by spraying molten aluminum as it approaches the lunar surface.

2020 Hackaday Prize Reveals Four Open Challenges And New Dream Team Program

The 2020 Hackaday Prize begins right now. Our global engineering challenge seeks solutions to real-world problems. If you like to come up with creative solutions to tough problems, four non-profits can use your help. We need hackers, designers, and engineers throughout the world to work on designs for conservation, disaster relief, renewable resources, and assistive devices.

This is the seventh year of the Hackaday Prize, and like past years we want to see your ideas take shape, so share your design process in detail as a project page on Over $200,000 in prizes are at stake, with a $50,000 prize for the all around best solution which will then be designed for manufacture at Supplyframe’s DesignLab, produced in a limited run, and deployed in the field.

New this year is our partnership with non-profits that have each outlined challenges they are facing. Eight projects, one top finisher, and one runner up from each of the four categories of challenges, will receive $10,000 and $3,000 respectively. As with previous years, the bootstrap round offers some seed money for getting your prototype off the ground: up to $500 for each of the top twenty during early entry judging. There’s even a $5,000 wildcard prize for entries that don’t specifically address challenges from the four categories. Here’s a taste of the categories you can work on:

  • Develop solutions to combat invasive species in marine and island environments, and help craft tools for protecting our natural ocean landscapes
  • Low cost tools for use in the field like a heat sealers/welders, and medical devices like IV fluid warmers
  • Adaptive technologies for workstations like trackballs, joysticks, and large button controllers
  • Modular add-ons for earthen housing for connectivity, light, heating, and water storage

Plasma “Ghosts” May Help Keep Future Aircraft Safe

Air-to-air combat or “dogfighting” was once a very personal affair. Pilots of the First and Second World War had to get so close to land a hit with their guns that it wasn’t uncommon for altercations to end in a mid-air collision. But by the 1960s, guided missile technology had advanced to the point that a fighter could lock onto an enemy aircraft and fire before the target even came into visual range. The skill and experience of a pilot was no longer enough to guarantee the outcome of an engagement, and a new arms race was born.

An F-15 launching flare countermeasures.

Naturally, the move to guided weapons triggered the development of defensive countermeasures that could confuse them. If the missile is guided by radar, the target aircraft can eject a cloud of metallic strips known as chaff to overwhelm its targeting system. Heat-seeking missiles can be thrown off with a flare that burns hotter than the aircraft’s engine exhaust. Both techniques are simple, reliable, and have remained effective after more than a half-century of guided missile development.

But they aren’t perfect. The biggest problem is that both chaff and flares are a finite resource: once the aircraft has expended its stock, it’s left defenseless. They also only work for a limited amount of time, which makes timing their deployment absolutely critical. Automated dispensers can help ensure that the countermeasures are used as efficiently as possible, but sustained enemy fire could still deplete the aircraft’s defensive systems if given enough time.

In an effort to develop the ultimate in defensive countermeasures, the United States Navy has been working on a system that can project decoy aircraft in mid-air. Referred to as “Ghosts” in the recently published patent, several of these phantom aircraft could be generated for as long as the system has electrical power. History tells us that the proliferation of this technology will inevitably lead to the development of an even more sensitive guided missile, but in the meantime, it could give American aircraft a considerable advantage in any potential air-to-air engagements.

Electric Vehicles Continue The Same Wasteful Mistakes That Limit Longevity

A while back, I sat in the newish electric car that was the pride and joy of a friend of mine, and had what was at the time an odd experience. Instead of getting in, turning the key, and driving off, the car instead had to boot up.

The feeling was of a piece of software rather than a piece of hardware, and there was a tangible wait before the start button could be pressed. It was a miracle of technology that could travel smoothly and quietly for all but the longest journeys I could possibly throw at it on relative pennies-worth of electricity, but I hated it. As a technologist and car enthusiast, I should be all over these types of motor vehicles. I live for new technology and I lust after its latest incarnations in many fields including automobiles.

I want my next car to have an electric motor, I want it to push the boundaries of what is capable with a battery and I want it to be an automotive tour de force. The switch to electric cars represents an opportunity like no other to deliver a new type of car that doesn’t carry the baggage of what has gone before, but in that car I saw a future in which they were going badly astray.

I don’t want my next vehicle to be a car like my friend’s one, and to understand why that is the case it’s worth going back a few decades to the cars my parents drove back when when jumpers were goalposts, and the home computer was just a gleam in the eye of a few long-haired outsiders in California.

Crunching Giant Data From The Large Hadron Collider

Modern physics experiments are often complex, ambitious, and costly. The times where scientific progress could be made by conducting a small tabletop experiment in your lab are mostly over. Especially, in fields like astrophysics or particle physics, you need huge telescopes, expensive satellite missions, or giant colliders run by international collaborations with hundreds or thousands of participants. To drive this point home: the largest machine ever built by humankind is the Large Hadron Collider (LHC). You won’t be surprised to hear that even just managing the data it produces is a super-sized task.

Since its start in 2008, the LHC at CERN has received several upgrades to stay at the cutting edge of technology. Currently, the machine is in its second long shutdown and being prepared to restart in May 2021. One of the improvements of Run 3 will be to deliver particle collisions at a higher rate, quantified by the so-called luminosity. This enables experiments to gather more statistics and to better study rare processes. At the end of 2024, the LHC will be upgraded to the High-Luminosity LHC which will deliver an increased luminosity by up to a factor of 10 beyond the LHC’s original design value.

Currently, the major experiments ALICE, ATLAS, CMS, and LHCb are preparing themselves to cope with the expected data rates in the range of Terabytes per second. It is a perfect time to look into more detail at the data acquisition, storage, and analysis of modern high-energy physics experiments.

A Redox Flow Battery Made From Iron Industry Waste

Researchers at the University of Southern California have found a way to make an effective and competitive redox flow battery out of the iron industry’s waste products.  Luckily for us, the results of the paper were posted on an open journal and we could take a look into the tech behind this battery.

As electric utilization, adoption of electric cars, and the use of renewable power continues to rise, engineers all over are searching for the perfect utility scale battery. We have all heard about Tesla’s 100MW lithium battery pack in South Australia. The system is a massive success and has already paid itself back. However, engineers all over were quick to point out that, until we have a breakthrough, Lithium cells are just not the right choice for a utility system in the long run. There has to be a better solution. Continue reading “A Redox Flow Battery Made From Iron Industry Waste”
