Antenna Mount Designed For On-The-Go SDR

Software-defined radio is all the rage these days, and for good reason. It eliminates or drastically reduces the amount of otherwise pricey equipment needed to transmit or even just receive, and can pack many more features than most affordable radio setups otherwise would have. It also makes it possible to go mobile much more easily. [Rostislav Persion] uses a laptop for on-the-go SDR activities, and designed this 3D printed antenna mount to make his radio adventures much easier.

The antenna mount is a small 3D printed enclosure for his NESDR Smart Dongle with a wide base to attach to the back of his laptop lid with Velcro so it can easily be removed or attached. This allows him to run a single USB cable to the dongle and have it oriented properly for maximum antenna effectiveness without something cumbersome like a dedicated antenna stand. [Rostislav] even modeled the entire assembly so that he could run a stress analysis on it, and from that data ended up filling it with epoxy to ensure maximum lifespan with minimal wear on the components.

We definitely appreciate the simple and clean build which allows easy access to HF and higher frequencies while mobile, especially since the 3D modeling takes it a step beyond simply printing a 3D accessory and hoping for the best. There’s even an improved version on his site here. To go even one step further, though, we’ve seen the antennas themselves get designed and then 3D printed directly.

An Open Source PowerPC Notebook Edges Closer

Back in 2020, we reported on the effort to create a brand new open-source laptop platform using the PowerPC architecture. At the time they had big plans and a PCB design, and we’re very pleased to report that in the intervening two years they’ve progressed to the point of now having some real prototypes ready for testing.

Some might question why this should be necessary, after all there are plenty of laptops and more than one commonly available processor platform. But that’s to miss the point of open source hardware, that it’s as much about plurality as functionality. But if you’ve only encountered the PowerPC architecture in slightly older Macs and some game consoles, what’s the chip powering this device? The answer is, not one of those venerable chips, but the NXP T2080, a 1.8 GHz quad-core device that boasts a respectable power for a laptop.

There is of course many a hurdle still to be crossed between prototype and final device, but given the challenge of a functioning laptop it’s impressive for them to have reached this milestone at all. We look forward to seeing further iterations, and maybe, just maybe, a finished device one day. Our original coverage is here.

Are Slabtops The Future Of Computing?

The most popular computer ever was the Commodore 64 with its computer-in-a-keyboard form factor. If you have a longing for a keyboard computer with more modern internals, one of the easiest solutions today is to pull the screen off a laptop.

[Umar Shakir] wanted to see what the fuss was about regarding a recent Apple patent and took the top lid off of his M1 Macbook Air and turned it into a “slabtop.” The computer works great wired to a monitor but can also be used wirelessly via AirPlay. The approach doesn’t come without its downsides, of course. Newer MacBooks can’t access recovery mode without the built-in screen, and some older models had their WiFi antennas in the top lid, so making one into a slabtop will leave you desk-bound.

While [Shakir] focuses on MacBooks, this approach should work with any laptop. Apparently, it’s a cottage industry in China already. Back in the day, my own daily driver was a Pentium-powered laptop with its broken LCD (and lid) removed. It worked great with whatever CRT was nearby.

Laptoppin’ Like 1975

When we first saw the PZ1 laptop — a 6502 laptop-style computer with a small display and 512K of RAM — we couldn’t help but think of the old AIM 65 computer from Rockwell, although that only had 1K of memory. The other thing the AIM didn’t have was an ancillary microcontroller to help out that is way more powerful than the main processor.

There are actually several versions of the PZ1 and you can find some very detailed information over on Hackaday.io and GitHub. Recently, [Adam] release version 2.0 and tested some PC boards that are working well.

MNT Reform Goodness, Now Even Smaller With Pocket Reform

You might have already seen the pretty pictures in pastel colors online — a small netbook-like computer with a full-size keyboard. This, while a render, is what the MNT Pocket Reform is going to look like. Reminiscent of the netbook aesthetic in all the right ways, it’s a small device with a mechanical keyboard taking as much space as possible, trackball for navigation, and we assume, exactly the kind of screen that’d be comfortable to use.

We’ve reviewed the MNT Reform a year ago, and this device inherits a lot of its good parts. The motherboard’s connectivity is likely subject to change, but on the motherboard renders, we can spot three USB-C ports, a Micro HDMI port, a microSD card slot, ix Industrial Ethernet, and M.2 B-key and M-key slots for WWAN and SSD cards respectively.

If you expected computational specs, there isn’t really a specific CPU+RAM configuration announced – for a good reason. The Pocket Reform takes advantage of the CPU card concept designed into the MNT Reform – able to take a card with an NXP i.MX8M CPU, Raspberry Pi CM4, Pine SOQuartz, a Kintex-7 FPGA, or any of the cards yet to be developed. The design files are open-source, the prototype motherboards have been ordered, mechanical usability aspects have been worked through. This is a very compelling project, and we can’t wait to see it bear fruit!

dual screen cyberdeck

Ditch The Laptop For The Tabletop

The idea of a cyberdeck is simple. A relatively portable case that is primarily a keyboard with some screen attached. Cyberdecks often try to hit a particular aesthetic or vibe rather than focusing on usability or practicality. [Carter Hurd] took a step back and asked himself what would be a cyberdeck-like system that he could practically use every day.

[Carter’s] build is a prototype that allows him to try out the form factor and use it as a daily driver, so many decisions were made to speed up the build and get something functional. For example, rather than spend the time tweaking and printing his own keyboard, he used an off-the-shelf keyboard he knew he liked. While a framework motherboard would have been perfect for something like this, they, unfortunately, weren’t available when [Carter] started the build. So [Carter] used a used gaming laptop for the task. He had hoped to drive the display directly from the motherboard as many laptops use embedded DisplayPort internally. Unfortunately, this didn’t work as the motherboard didn’t support the resolution he was trying to drive at, so he just used the external port to drive the screen. A 3d printed base fits underneath the keyboard to hold the laptop motherboard with little extensions for bits that don’t work well, such as the wifi card. The chassis also has a slot that allows a secondary display to slot right in.

Ultimately, it is something of a modern-day typewriter and something like a cyberdeck. Either way, we love it. Video after the break.

Modular Laptop Maker Provides Mainboard Documentation For Non-Laptop Projects

If you’ve been following the latest advancements in computing for a while, you already know that there’s a big problem with laptops: When they’re no longer useful as a daily driver, it can be a struggle to find a good use for all its parts. Everything is proprietary, and serious amounts of reverse engineering are required if you decide to forge ahead. This is where Framework, a laptop company building modular laptops comes in. They’ve made it clear that when you upgrade your Framework laptop with a new mainboard they want you to be able to continue to use the old mainboard outside of the laptop.

When it's done powering your laptop, use it for a cyberdeck?
When it’s done powering your laptop, use it for a cyberdeck?

To that end, Framework have provided 2D mechanical drawings of their mainboard and 3D printable cases that can of course be modified as needed. “But what about peripherals?” you might ask. Framework has provided pinouts for all of the connectors on the board along with information on which connectors to use to interface with them. No reverse engineering needed!

While it’s possible to buy a mainboard now and use it, their stated goal is to help people make use of used mainboards leftover from upgrades down the line. With just a stick of memory and a USB-C power adapter, the board will spring to life and even has i2c and USB immediately available.

What would you do with a powerful Intel i5-1135G7 mainboard? Framework wants to know, and to that end, they are actually giving away 100 mainboards to makers and developers. Mind you this is a program created and ran by Framework — and is not associated in any way Hackaday or our overlords at Supplyframe.
