As part of an investigation into opposition to 5G mobile phone networks in the English town of Glastonbury the BBC reporter [Rory Cellan-Jones] shared details of a so-called 5G protection device that was advertised as casting a bubble of 5G-free space around its owner. This set [The Quackometer] writing, because as part of his probing into the world of snake-oil, he’s bought just such a unit and subjected it to a teardown.
What he has is a plastic project box with a graphic on top, a switch and green LED on the side, and a battery compartment on its rear. Opening the battery compartment reveals a standard 9 V alkaline cell, but the real interest comes when the cover is removed. There is a copper cylinder with a coil of wire round it, though the wires from the coil to the battery have been cut. The active part of the device is simply a battery powering an LED through a switch, as he puts it the device is a £50 ($61) poor quality torch (flashlight). Of more interest is the copper cylinder, which he identifies as a short piece of copper water pipe with two end caps. He doesn’t open it up, leaving us to expect that whatever mystical component deals with the RF must be concealed within it. This is not the usual Hackaday fare, but we know our readers are fascinated by all new technologies and will provide plenty of speculation as to how it might work in the comments.
The BBC story is worth a read to give a little background. If you are a non-Brit and you have heard of Glastonbury it is probably for the famous summer music festival held on a neighbouring farm, but the town is also famous for its connections with Arthurian legend and in recent decades for having become a centre for New Age mysticism. It has also become something of a hotbed of activism against the spread of 5G mobile networks, and has made the news this week because of concerns over the impartiality of a report condemning the technology released by its local government. If you have an interest in the 5G saga then brace yourselves for this document being used to lend a veneer of official credibility.
We’ve spent a while covering 5G issues, and given that some aspects of the story are shaping up to be a gift to technical journalists that keeps on giving, no doubt we’ll bring you more in due course. Devices such as the one featured here could even supplant audiophile products as a source of technical wonderment!
Thanks [Deus Ex Silicium] for the tip.
The 2019 Geneva International Motor Show has a number of “concept” vehicles. These are vehicles that usually include some cool feature that isn’t really practical — at least today. For example, in the past, concept cars have had adjustable color interior lighting, plug-in hybrid engines, and power windows — all things that would eventually become commonly available. However, today’s advances in computer-generated graphics have meant you can show things you can’t begin to build. Case in point: Goodyear has a video touting the Aero — a solid car tire that doubles as a propeller for your garden variety flying car.
To us, the thing looks more like a science fiction movie trailer than anything remotely practical. Four relatively small wheels with no central hub can flip and provide enough lift to propel a sizeable vehicle skyward. Even more interesting, is to transition modes from ground to flight, the vehicle balances on two wheels while using only two as propellers to generate lift.

If you’re looking for an Open Source computer, good luck. The RISC-V stuff isn’t there yet, and with anything else you’re going to be dealing with NDA’d Intel, AMD, or some other proprietary cruft. System76, however, makes the most big-O Open computer, and they will be announcing a new Open computer called the Thelio next month. It was on display at the Open Hardware Summit, although smartly there were no pictures taken of this box. Liliputing has reported on it, but there are a few things wrong with that speculation. No, it’s not RISC-V. We’re looking at x86 here. It’s a desktop. It has wood (walnut or maple). It doesn’t have enough cold cathode lighting to blind you, but I guess that’s a matter of taste. Everything will be announced in October.
I have a plan in the works to sell snake oil to people. Actually, it’s not snake *oil*, but it is derived from snakes. There are rattlesnake farmers out there, who breed snakes for meat (tastes like chicken!) and their skins for boots. The fascia of the skins is disposed of when this leather is being prepared, and this can be used as the base component of a glue, or something resembling gelatin. It’s basically no different than fish or animal glue, except it’s from snakes. This can be used as one of the ingredients in gummy candy. This is my plan: I’m going to sell snake oil, except it’s really snake-based gummies. They promote digestion and get rid of ions in your body, or something. Better living through snake gummies.
The paragraph you just read is a better business plan than this bit of snake oil. It’s a battery that recharges itself. It’s unclear if it recharges itself over time; if if it just recharges itself automatically, wouldn’t the battery just have more energy in it? It’s hitting all the checkmarks of snake oil too: there are references to Tesla being a ‘forgotten genius’, zero-point energy fields, and a countdown timer to their crowdfunding campaign. This rabbit hole goes deep.
Did you know Hackaday has a Retro Edition, specifically designed for old computers that somehow have web browsers? It’s true! Sometimes, we even add pics of people pulling the Retro Edition up on their ancient devices. [Steven McDonald] wondered if his Blackberry counted. Sure thing! If you can pull up the Retro Edition on your ancient computer, we’ll mention it in the Links post, too. We’re also taking suggestions on how to improve the Retro Edition; I’ll get around to improving it eventually.
