You may believe that CD and DVD players have seen their last days, yet they are treasure troves for DIY ventures. Open one up, and you will discover stepper motors, laser assemblies, DAC chips, power circuits, infrared receivers, and precision mechanical elements — components that remain perfectly functional even if the device itself is no longer operational.
These components were designed to endure countless hours of disc spinning, data reading, and signal converting, making them sturdy. They are dependable, over-engineered in the most positive sense, and unexpectedly adaptable for hobby electronics, robotic applications, audio modifications, or custom control systems.
If you have one of these gathering dust in a cupboard or are about to dispose of it, consider pausing. Instead of adding to electronic waste, you can actually transform these into something beneficial. Here are five intriguing ways to revitalize that old CD or DVD player of yours.
Have you ever opened an old DVD writer? Inside, you’ll find a laser diode, sled mechanism, and stepper motor, which just so happen to be everything you require to create a miniature laser engraver. An Argentine maker named Aoshido discovered how to convert multiple DVD drives into a functioning engraver. He arranged the sled assemblies from two drives in an XY layout — one managing horizontal movement, the other vertical. An Arduino running GRBL firmware controlled the steppers, while the laser
Read MoreThe Apple Watch continues to be one of the top-selling smartwatches, with a variety of models available. Its reputation stems from its smooth integration with iOS, user-friendly watchOS interface, and dependable health and fitness tracking capabilities. As of July 2025, whether your priorities lie in fitness, wellness, or daily productivity, there’s an Apple Watch suited for everyone.
Regardless of whether you have the latest Apple Watch Series 10 or an earlier version, one fact remains: Apple Watch batteries deteriorate over time. Similar to all lithium-ion batteries, the battery inside your Apple Watch undergoes chemical aging, limiting its charge retention as time progresses. Frequent usage, elevated temperatures, and standard charging cycles all contribute to this gradual performance decline.
Apple states that a standard Apple Watch battery is intended to maintain up to 80% of its initial capacity after 1,000 complete charge cycles. You can track your device’s battery health directly within the watch settings to identify if a replacement is necessary.
Apple Watch battery duration is influenced by several factors, including the specific model you possess. For instance, when it’s brand new, the Apple Watch Series 10 is rated for as much as 18 hours of battery life per charge. The more robust and premium Apple Watch Ultra 2 significantly enhances performance, offering up to 36 hours of battery life in standard mode and up to 72 hours when utilizing Low Power Mode.
### How to assess your Apple Watch battery health
While it isn’t necessary to check your Apple Watch battery health every day, it’s wise to review it from time to time, especially if you encounter issues like unexpected shutdowns or if your watch isn’t lasting as long on a full charge as it used to. These indications often suggest battery degradation, a normal aspect of any lithium-ion battery’s lifecycle.
The primary metric to examine is the Maximum Capacity, which shows how much charge your Apple Watch battery can hold in comparison to when it was new. For example, if the maximum capacity significantly falls below 100%, your watch may struggle to last a full day on one charge. This figure aids in assessing whether your battery is still in sound condition or if it’s time for a replacement.
You can verify your battery health on your Apple Watch in just a few straightforward steps. Here’s what to do:
1. Press the crown to access the Home Screen.
2. Tap on the Settings icon.
3. Tap on Battery.
4. Scroll down to Battery Health.
When reviewing your Apple Watch battery health, you will see a Maximum Capacity percentage. A healthy battery usually displays above 80%, and anything under that may necessitate a battery replacement, no matter how long you’ve had the watch. Although a brand-new Apple Watch should show nearly 100% capacity, Apple acknowledges that minor discrepancies can occur due to the time between manufacture and purchase. Following regular usage, it’s typical to observe a decrease in capacity.
### How to enhance your Apple Watch battery
Apple provides several integrated features to optimize Apple Watch battery life, and keeping your device updated guarantees that you benefit from the latest energy-efficiency enhancements in watchOS. Activating Low Power Mode (accessible via Control Center or Settings) turns off non-essential features, like always-on display, background heart and oxygen monitoring, and cellular connections.
For long-term battery health maintenance, Apple suggests using Optimized Battery Charging, available in watchOS 7 and later, which learns your routine and pauses charging past 80% when necessary. Optimized Charge Limit further fine-tunes charging behavior to maintain battery longevity on supported models (Series 6 and later, SE, and Ultra). You can also minimize screen wake-ups by deactivating Wake on Wrist Raise, or activating Theater Mode, and enabling Bluetooth on your iPhone ensures efficient syncing and reduced power drain on the watch.
While exercising, you can enable Power Saving Mode, which will turn off the heart rate sensor. Simply navigate to the Apple Watch app on your iPhone, select My Watch, and then choose Workout. From there, you can activate Power Saving Mode; however, keep in mind that calorie burn estimates may be less precise.

As per the recent release of Mark Gurman’s Power On newsletter, Apple is making notable progress to venture into the AI search domain, signaling a shift from its earlier hesitance to embrace chatbot solutions. This transition comes as Apple seeks to bolster its contributions to artificial intelligence, particularly in light of mounting rivalry.
In the past, Apple Intelligence has encountered difficulties, with features such as Genmoji and Notification Summaries garnering only modest feedback. Additionally, the highly awaited revamp of Siri has experienced delays, postponing its rollout by more than a year. This situation has led Apple to reevaluate its tactics and competencies in AI.
To rejuvenate its initiative, Apple has formed a new internal group referred to as “Answers, Knowledge, and Information” (AKI). This group is responsible for investigating various internal AI offerings, aiming to forge a search experience similar to ChatGPT. Although there are some philosophical hesitations among Apple leaders about AI, the creation of AKI marks a decisive engagement in advancing this field.
The team is headed by Robby Walker, a former executive affiliated with Siri, who has previously voiced concerns regarding delays in Siri’s progression. Walker’s guidance is anticipated to direct the new endeavor towards a more competitive AI search solution. Apple has also expressed interest in partnering with AI startups like Perplexity, which focuses on AI-enhanced search engines, further underscoring its aspiration to innovate in this domain.
Although the initiative remains in its nascent phase, the prospect of Apple launching a robust AI search experience is stirring enthusiasm among users and industry analysts alike. As the tech behemoth continues to hone its AI capabilities, many are keen to observe how this new path will evolve and its implications for the future of search technology.

The advancements from the AKI group will be monitored closely as they strive to provide a new AI-powered search experience that could transform how users engage with information on Apple devices.
Read MoreiOS 26 public beta has been available for several days now, but I’ve been experimenting with iOS 26 since the initial developer beta. Apple has made significant improvements over the last two months, but it still remains imperfect, particularly if you plan to use the software on your main device.
iOS 26 introduces a variety of new features, such as the completely revamped Liquid Glass design, enhanced integration of ChatGPT, new Continuity capabilities when you have iPadOS 26, macOS Tahoe 26, or watchOS 26 installed, and more. Nevertheless, making the most of these fresh features requires readiness for all the bugs and complications that come with this beta. After all, this is a test version, and many issues won’t be resolved until Apple launches the official version later this year.
While the overall experience should improve significantly throughout the beta cycle, there’s a reason Apple doesn’t immediately release this version to the public. Indeed, we’ve identified six reasons to bypass the iOS 26 public beta and hold out for the official release later this fall.
affordable testing tools.” That was true a few years back, prior to Google enabling the download of Android applications from the Play Store. The introduction of Steam has been a significant development, allowing users to convert their laptops into gaming devices.
For individuals lacking a contemporary gaming PC or console, a Chromebook equipped with Steam provides numerous opportunities. You can now enjoy nearly any game on a Chromebook.

Even if your Chromebook has sufficient power to run Steam, that doesn’t guarantee you can play every available game. However, you can access some, albeit with reduced graphical quality if you only meet the basic hardware requirements.
Local 12, users of Gmail have indicated they are receiving phone calls from individuals who assert they work for Google, even showing a caller ID that reflects this claim. Once engaged, the caller informs them that their Google account has been breached in some manner.
The fraudsters then propose to send a verification code or reset link to the user’s phone, stating that it will rectify the compromised account. Often, these links can closely resemble the genuine links you might receive from legitimate technology companies when addressing account concerns. However, it’s crucial not to trust them, as clicking on them and signing in grants the scammers unrestricted entry to your Gmail account. Similar attempts to infiltrate consumer accounts have also been observed on Apple devices.
