Many in the community are skeptical about the security of commercial smart home devices, and for good reason. It’s not like you have to look far to find examples of poorly implemented systems, or products that are abandoned by their manufacturers and left without critical security updates. But the design flaw in this video doorbell really drives home how little thought some companies give to their customer’s security.
As explained by [Nova Mostra], and demonstrated in the video after the break, all you need to do if you want to get into a home equipped with one of these vulnerable door bells is pop the unit off the wall and hit it with 12 volts DC.
Incredibly, the terminals that connect to the electronic lock inside the house are completely accessible on the back of the unit. They even labeled them, on the off-chance the robber forgets which wire is which. It’s not even as though the thing is held on with some kind of weird security screws, it’s just a garden variety Phillips.
In the video, [Nova Mostra] even shows he used a little gadget attached to a QuickCharge USB battery bank to get a portable 12 VDC source suitable for tripping these locks. Which, interestingly enough, is based on a trick he read about in the Hackaday comments. Something to consider while penning your next comment on these storied pages.
[Nova Mostra] says he’s reached out to the company to get their side of the story, but so far, hasn’t received a response. We aren’t surprised, this is a fundamental flaw in the product’s execution. Clearly they wanted to make an easy to install device that doesn’t require any additional electronics in the house, and this is the inevitable end result of that oversimplification. All the more reason to roll your own smart doorbell.

A laser cutter is a useful tool to have in any workshop. While many hackers use them for their cutting abilities, it’s important to remember that they can be great as engravers, too. [Wrickert] was well aware of this when he set his to work, producing attractive packaging for his Tindie orders.
[Wrickert] sells a variety of small PCB-based devices on Tindie, and it’s nice to have something to package them up with, rather than just sending a bare board. To do this quickly and effectively, KiCAD is used to help generate the packaging from the original PCB geometry itself. The board outlines are exported as an SVG file, reopened in KiCAD, and then used to create the required cardboard parts. The laser can then also be used to engrave the cardboard too.
It’s a tidy packaging solution that requires no messy inks or printers, and can be designed in the same software as the device itself. We’ve covered this area before, talking about what it takes to go from a home project to a saleable kit. If you’re in the game, you might find [Wrickert]’s hack to be just the ticket!

It is common wisdom that solderless breadboards are only good for low frequencies. But how fast can they really go? There’s been a contest going on to see who can make the fastest breadboard-mounted oscillator and [Joe Smith] has been trying to keep his leading position. He’s already managed 6 GHz and now he’s shooting for 20 GHz, as you can see in the video below.
One of the biggest challenges at these frequencies is just measuring your output. You may have a scope, but how does it do at 20 GHz? So half of the story is how [Joe] managed to monitor his output.
You’ll see in the video that while the breadboard is just an ordinary-looking breadboard, it is covered with strange-looking cages, feed lines, and shields. The rules prohibit using ICs and crystals, so if you want to compete, you’ll need to brush up on your RF skills.
If you enjoy this sort of thing, there are several older videos on the topic from [Joe.] We aren’t sure what practical use there is to building a microwave transmitter on a breadboard, but we get the sport of it.
We see a number of contestants that try to unseat the ubiquitous solderless breadboard, but none of them seem to stick. Maybe if it isn’t broke, there’s no need to fix it.

Every home needs renovations after a few decades, and the International Space Station is no different. This fall, they’ll be getting a new Universal Waste Management System (UWMS), aka a new toilet.
Though the news coincides with increased traffic to the ISS, this move stems from a more serious issue with bacterial contamination during longer-term space travel. Today’s ISS toilets already recycle urine back into potable water and scrub the air reclaimed from solid waste as it gets compacted and stored. The new UWMS will act more like a food dehydrator, reducing the water content as much as possible to save on space, and petrifying the poo to inactivate the bacteria.
The current commode on the American side of the ISS was designed in the 1990s and is based on the Space Shuttle’s facilities. It has a funnel with a hose for urine and a bag-lined canister with a seat for solid waste, both of which are heavily vacuum-assisted.
Though the current toilet still does everything it’s supposed to do, there is room for improvement. For instance, women find it difficult to engage both parts of the system at the same time, and almost everyone prefers the toe bars on the Russian toilet to the more encumbering thigh bars on the American throne. Also, the current commode’s interface is more complicated than it needs to be, which takes up valuable crew time.

The most intimate change is probably the seat design. In a weightless environment, it’s more like a hovering zone than a throne. According to the white paper (PDF), the UWMS seat has homing ridges and “includes a tailbone section to encourage crew cheek separation”. Maybe the vacuum works against separation? We’re not sure.
Although the new latrine wasn’t designed specifically for the ISS, the crew members will make excellent guinea pigs to test the new features. And they don’t have to send it back or anything — it will stay up there until it breaks, or until the ISS is retired, whichever comes first. A second unit is being built for those longer-term missions and will be installed on the Orion capsule, which is slated to return to the Moon in 2024.
