Digital pregnancy tests are almost as effective as the original IBM PC

Pregnancy tests used to be pretty simple sticks to pee on, but the move to digital versions has turned them into tiny computers, almost as powerful as the original IBM PC. Fascinated by the digital age of pregnancy tests, Twitter users Telephone and xtoff recently took apart examples from Walmart and Clearblue to show what’s really going on inside.

Each test, which costs less than $ 5, includes a processor, RAM, a coin cell battery, and a tiny LCD screen to display the result. The processor is an 8-bit Holtek microcontroller with 64 bytes of RAM, capable of running at 4 or 8 MHz depending on the battery configuration. It may sound very simple, but the chip is surprisingly complex.

“You might think it is very limited because it only has 64 bytes of RAM, but it actually uses a pipelined architecture to run at 1 instruction per cycle, which gives it pretty good performance for a 4 MHz processor.” explains Fung on the fun Twitter thread.

Fung suggests that the device “is probably faster at processing numbers and basic I / O than the CPU used in the original IBM PC.” The original IBM PC was based on the Intel 8088 microprocessor, an 8-bit chip running at 5 MHz. The difference is that this is a pregnancy test that you pee on and then throw away.

You might assume that adding an LCD screen and a processor to digitize this pregnancy test would improve the accuracy or modernize the test’s performance, but this is certainly not the case. This digital pregnancy test still includes a paper strip to measure the chemical reaction you create when you urinate on the strip.

The paper strip inside acts like a wick, so when wet, it activates the battery and turns on the device. The device then uses three LEDs and two photosensors to read the lines on the paper strip, which would normally provide the result of a pregnancy test. The processor, RAM, battery, and LCD literally exist to read the paper strip and improve the legibility of the test, displaying “pregnant” or “not pregnant” instead of the usual lines that can be difficult to read.

Unfortunately, the chip inside is not programmable, so people cannot Doom use these digital pregnancy tests. I would recommend reading full foone Twitter thread as this is an exciting analysis. While these digital pregnancy tests seem like an incredible waste of plastic and electronics, I’m just grateful that humanity has moved away from squirting frogs with urine to check pregnancy.

Samsung plans to release a tablet with a folding screen

BUT Samsung has already made it clear that it intends to continue betting on foldable phones, which will include the company’s new Galaxy Z Fold 4 and Galaxy Z Flip 4 models this week.

Apart from wanting to contribute to the foldable mobile phone category, a South Korean tech company is also known to be developing a foldable screen tablet. Who says this is the Ice Universe page on the Chinese social network Weibo (via Android Headers), referring to the fact that the tablet in question will be called the Galaxy Tab Fold.

The page in question suggests that the Galaxy Tab Fold will be announced at the same Galaxy Tab S9 launch event that Samsung usually holds in the first quarter of the year.

It is possible that the presentation of these two tablets will take place in early 2023, but given that we had to wait two years between the Galaxy S7 (2020) and Galaxy S8 (2022), there is also a possibility that the Galaxy Tab Fold and Galaxy Tab S9 will appear only in 2024.

“The Truth About Weight” is the title of a new podcast promoted by Novo Nordisk that aims to help “understand what obesity is: a chronic disease that can be influenced by many factors, from genetics to lifestyle.”

The podcast is hosted by host Vanessa Oliveira and general and family medicine physician Margarida Santos, joined by special guests for “informal and intimate” conversations about obesity and overweight.

The first two episodes of the podcast are now available on Spotify, Youtube, Google Podcasts, Apple Podcasts and Pocket Casts, featuring endocrinologist Joana Menezes and singer Ana Bacalhau. Psychiatrist Julio Machado Vas is another of the already confirmed names.

“We all have a role to play in promoting health literacy and responsible communication on issues that pose real public health challenges, such as obesity. This podcast is for knowledge sharing where the truth about weight will be revealed. Our goal is to help better understand obesity and motivate the search for adequate support to overcome the challenges associated with this complex disease and thus live a fuller and healthier life,” Paula Barriga, CEO of Novo Nordisk Portugal, said in a statement.

This is an initiative of Novo Nordisk in partnership with ADEXO – the Portuguese Association of Obese and Formerly Obese Patients in Portugal, SPEO – the Portuguese Society for the Study of Obesity and SPEDM – the Portuguese Society for Endocrinology, Diabetes and Metabolism.

There are issues that are delaying the release of iPadOS 16

September is usually the month of Apple. The new iPhone 14, Apple Watch Series 8 and AirPods Pro 2 are expected to launch. And in the area of ​​operating systems, iOS 16, watchOS 9 and iPad OS 16 are expected to be released. iPadOS 16 is expected to arrive no earlier than October.

It’s common for iOS and iPadOS to reach users at the same time, but flaws in the iPad’s operating system app will change the release date of the new software version this year.

It’s the new blame for the delay Multitasking Stage Manager what kind, According to The Verge, development will take longer than expected.. As in previous years, iPadOS 16 may be released in its final version without some previously announced features.

At this point in the beta, the team working on Stage Manager was very critical because the software was confusing and resulted in a lot of bugs. Besides, it is only compatible with iPad with M1.

The Stage Manager will allow you to resize windows, overlap them, or drag and drop multiple applications at the same time. In an interim version, when using an iPad with an external display, the system locks up and returns the user to the home screen. From the news, we also noticed that when using the window resizing option, some applications react unexpectedly.

Since the release of the new version of the operating system for Apple tablets is delayed until September, the release date may change again to coincide with the presentation of new models.
