Recovering Metal From Waste

Refining precious metals is not as simple as polishing rocks that have been dug out of the ground. Often, complex chemical processes are needed to process the materials properly or in high quantities, but these processes leave behind considerable waste. Often, there are valuable metals left over in these wastes, and [NerdRage] has gathered his chemistry equipment to demonstrate how it’s possible to recover these metals.

The process involved looks to recover copper and nitric acid from copper nitrate, a common waste byproduct of processing metal. While a process called thermal decomposition exists to accomplish this, it’s not particularly efficient, so this alternative looks to improve the yields you could otherwise expect. The first step is to react the copper nitrate with sulfuric acid, which results in nitric acid and copper sulfate. From there, the copper sulfate is placed in an electrolysis cell using a platinum cathode and copper anodes to pass current through it. After the process is complete, all of the copper will have deposited itself on the copper electrodes.

The other interesting thing about this process, besides the amount of copper that is recoverable, is that the sulfuric acid and the nitric acid are recoverable, and able to be used again in other processes. The process is much more efficient than thermal decomposition and also doesn’t involve any toxic gasses either. Of course, if collecting valuable metals from waste is up your alley, you can also take a look at recovering some gold as well.

Thanks to [Keith] for the tip!

Nintendo Switch update lets you share screenshots to your phone or PC

Nintendo has released a new firmware update for the Switch, and for once it actually adds some features to the console’s barebones OS.

The biggest one is a new way to share screenshots and videos directly to your smartphone by scanning a QR code. The process is a little awkward, but it definitely beats the previous method of uploading everything to Twitter or Facebook first.

Here’s how it works:

You can also now copy screenshots and videos to your PC over USB.

Gathering Eclipse Data Via Ham Radio

A solar eclipse is coming up in just a few weeks, and although with its path of totality near the southern tip of South America means that not many people will be able to see it first-hand, there is an opportunity to get involved with it even at an extreme distance. PhD candidate [Kristina] and the organization HamSCI are trying to learn a little bit more about the effects of an eclipse on radio communications, and all that is required to help is a receiver capable of listening in the 10 MHz range during the time of the eclipse.

It’s well-known that certain radio waves can propagate further depending on the time of day due to changes in many factors such as the state of the ionosphere and the amount of solar activity. What is not known is specifically how the paths can vary over the course of the day. During the eclipse the sun’s interference is minimized, and its impact can be more directly measured in a more controlled experiment. By tuning into particular time stations and recording data during the eclipse, it’s possible to see how exactly the eclipse impacts propagation of these signals. [Kristina] hopes to take all of the data gathered during the event to observe the doppler effect that is expected to occur.

The project requires a large amount of volunteers to listen in to the time stations during the eclipse (even if it is not visible to them) and there are only a few more days before this eclipse happens. If you have the required hardware, which is essentially just a receiver capable of receiving upper-sideband signals in 10 MHz range, it may be worthwhile to give this a shot. If not, there may be some time to cobble together an SDR that can listen in (even an RTL-SDR set up for 10 MHz will work) provided you can use it to record the required samples. It’s definitely a time that ham radio could embrace the hacker community.

Enterprising developers are emulating PS2 games on the Xbox Series S and X

Photo by Tom Warren / The Verge

Developers have now made it possible to emulate PS2 games on the Xbox Series X and S using the RetroArch emulator — something that the PlayStation 5, a successor to the PS2, can’t.

Thanks to the Xbox Series X / S consoles’ “Developer Mode,” the emulation software can be added as a Universal Windows Application (UWA), allowing users to download a retail version of the emulation software directly to their console without tricky workarounds, so players don’t have to wait for a re-release to play an older favorite.

While RetroArch is able to emulate several different consoles, the compatibility for running PS2 games using the PCSX2 core is particularly notable because of how limited Sony’s PlayStation 5 is when it comes to backwards…

Component failure in NASA’s deep-space crew capsule could take months to fix


Engineers are racing to fix a failed piece of equipment on NASA’s future deep-space crew capsule Orion ahead of its first flight to space. It may require months of work to replace and fix. Right now, engineers at NASA and Orion’s primary contractor, Lockheed Martin, are trying to figure out the best way to fix the component and how much time the repairs are going to take.

In early November, engineers at Lockheed Martin working on Orion noticed that a power component inside the vehicle had failed, according to an internal email and an internal PowerPoint presentation seen by The Verge. The component is within one of the spacecraft’s eight power and data units, or PDUs. The PDUs are the “main power/data boxes,” for Orion according to the…
