Recycling Two XBox One Consoles into a 10 GB USB Flash Drive

-

Amidst the ongoing RAM & storage apocalypses, Mad Max-esque scenes are unsurprisingly developing, with the eMMC recycling project by [Chase Fournier] from a pair of XBox One S (‘XBone’) mainboards being just one more example. These mainboards come equipped with a 5 GB eMMC chip installed, alongside 8 GB of DDR3.

Removing the eMMC chips isn’t that complicated and after some reballing fun the chips were both installed on a carrier board with a Norelsys NS1081 controller IC. This provides a USB 3.0 interface and can connect to up to four SD or eMMC memories, with here just two channels used.

Although the eMMC testing device didn’t seem too happy with either chip, after mounting them on the PCB the controller could be programmed and saw both eMMC packages for a grand total of 10 GB storage.

Sequential read performance in CrystalDiskMark was about 140 MB/s while write performance was about 64 MB/s, which is zippy enough for smaller files. Not that you can store more than 10 GB on this USB drive anyway.

Turning the DDR3 ICs on the mainboard into proper DIMM or SODIMM sticks would also be an idea, as even such older memory tech keeps ramping up in demand. As for the XBone X variant with its 12 of GDDR5, that’s probably a harder proposition to repurpose, but recycling old consoles suddenly has become a lot more exciting.

Modern Radio Receiver Architecture: From Regenerative to Direct Conversion

-
Image
Modern radio receivers have a distinct advantage over the common early designs which I covered in my previous article . Most of the receivers you will have worked with over the past couple decades are designs by Edwin Armstrong ; regenerative, superregenerative, or most commonly superheterodyne. These are distinguished by a few fascinating key traits that bring both benefits and drawbacks. Today let’s dive into Mr. Armstrong’s receivers. I’ll also talk about DC receivers which, despite the name, are not made to listen to batteries. These are receivers you are much more likely to encounter in modern equipment. Regenerative and Superregenerative The regenerative receiver is all about doing more with less. You still see some of these in simple applications like RF remote controls. The idea derives from how an oscillator works. In a simple way of thinking, an oscillator is an amplifier with enough positive feedback that any tiny signal at the right frequency will amplify and then, throu...

Custom Macro Keyboard Looks Good in Wood

-
Image
There’s more than one way to make a mechanical macro pad, and this wooden wonder represents one of our favorites . [Tauno Erik] had an old rubber dome rectangle keyboard lying around that still worked, but the poor thing was missing some of its caps. After salvaging the controller, [Tauno Erik] got to work on the tedious task of figuring out the mapping of the matrix, which was made easier with a Python script. Almost every component of this beauty is wood, including the mounting plate and those thicc and lovely keycaps — their top layer is solid oak, and the bottom bit is birch plywood. In order to interface the ‘caps with the switches, [Tauno Erik] designed and printed connector pieces that sit inside the extra large keycaps and accept the stems of the key switches. Speaking of switches, we’re not sure if [Tauno Erik] ended up using Cherry green switches, browns, or a mix of both (that would be interesting), but each one is mounted on a custom PCB along with a diode and a pull-up ...

Build this Cyberdeck in a Cave with a Box of Scraps

-

Desktop 3D printing has been a big enabler for the cyberdeck community, as it’s allowed individuals to create unique frames and enclosures which would have been far more difficult and time consuming to produce using traditional methods. But what if you don’t have access to a well-stocked workspace, and need to do your building with the bare minimum of equipment? In that case, [ALX] recently put together a minimalistic design that can be assembled with off-the-shelf components and basic tools. It’s the ideal cyberdeck for the neophyte, as all the parts are widely available and relatively inexpensive. While it might not be a customized as something with a fully 3D printed frame, we think it nails the look and utility that are the hallmarks of a proper deck. The key to this build is the SmartiPi Touch case, which puts the Raspberry Pi and touch screen on a hinged panel. These hinges happen to be compatible with GoPro-style mounts, so with a few extension pieces, the panel can be lifted...
