NumLock, Ad-Free Apps & Party Lights: Tech Tips
Reader Tips Roundup: Enhancements and Tricks
Each week, we compile a selection of helpful suggestions submitted by our readers. This week’s collection focuses on automating NumLock activation, removing advertisements from applications on iOS devices, and creatively repurposing Christmas lights.
Automating NumLock Activation
A common request is to have the NumLock key enabled automatically upon system startup. This eliminates the need to press the NumLock key each time a computer is booted. Several methods exist to achieve this, often involving BIOS settings or registry modifications.
Ad Removal from iOS Apps
Readers have shared techniques for blocking advertisements within iOS applications. These methods typically involve utilizing content blockers or configuring DNS settings to prevent ad servers from loading. It’s important to note that supporting app developers through legitimate means is encouraged.
Transforming Christmas Lights into Audio-Responsive Displays
An inventive idea involves converting standard Christmas lights into a dynamic, audio-reactive display. This is accomplished by connecting the lights to a microcontroller and utilizing a sound sensor to modulate the light patterns based on ambient audio.
The result is a visually engaging party atmosphere where the lights pulse and change in sync with the music. This project requires some technical skill but offers a unique and festive outcome.

Activating NumLock at Startup Through a Registry Modification
A reader, Parthiv, has shared a useful registry hack to consistently enable the NumLock key upon system boot.
For years, Parthiv searched for a method to automatically activate NumLock, starting with Windows XP. Despite suggestions to check the BIOS settings, a solution wasn't found there.
The Registry Tweak Explained
The answer lies in modifying the Windows Registry. Specifically, the data entries labeled "InitialKeyboardIndicators" must be altered to a value of 2.
It’s important to only change entries that initially contain a numerical value, as some entries may represent directories.
To simplify this process, Parthiv created a .reg file to automate the changes. A corresponding file is also included to revert the modification, setting the values back to 0.
Sharing the Solution
We greatly appreciate Parthiv sharing this solution with our readers. This ensures that others facing the same issue can easily find a resolution through a simple search.
The .REG files provided by Parthiv are attached. For those who prefer to examine the code before execution, the contents of the NumLockOnBoot.reg file are detailed below:
NumLockOnBoot.reg File Contents
The following registry entries will be modified:
[HKEY_CURRENT_USER\Control Panel\Keyboard]
"InitialKeyboardIndicators"="2"[HKEY_USERS\.DEFAULT\Control Panel\Keyboard]
"InitialKeyboardIndicators"="2"[HKEY_USERS\S-1-5-18\Control Panel\Keyboard]
"InitialKeyboardIndicators"="2"[HKEY_USERS\S-1-5-19\Control Panel\Keyboard]
"InitialKeyboardIndicators"="2"[HKEY_USERS\S-1-5-20\Control Panel\Keyboard]
"InitialKeyboardIndicators"="2"[HKEY_USERS\S-1-5-21-51780718-2047605258-340133435-1000\Control Panel\Keyboard]
"InitialKeyboardIndicators"="2"[HKEY_USERS\S-1-5-21-51780718-2047605258-340133435-1001\Control Panel\Keyboard]
"InitialKeyboardIndicators"="2"
By implementing this registry change, users can ensure that the NumLock key is activated automatically each time their computer starts.
Eliminating In-App Advertisements on iOS Devices
A user named Nicole has shared a method for removing advertisements from iOS applications.
The Frustration with Persistent Ads
While generally supportive of allowing advertisements to sustain developers, Nicole found a specific situation compelling her to seek a solution. She prefers purchasing applications outright or upgrading to a premium, ad-free version when available.
However, certain applications only offer a free, ad-supported version without a paid alternative. This presents a challenge when the ad placement interferes with usability.
Specifically, the app's design inadvertently leads to frequent accidental clicks on the advertisement banner, creating a disruptive user experience.
The Solution: Disable iAds
Nicole discovered Disable iAds for iOS as a means to address this issue. This requires a jailbroken iPhone or iPad.
Installation involves adding the Kokoabim repository (http://apt.kokoabim.com/ios) to your device, as the application is not found in standard repositories like BigBoss.
Once the repository is added, simply search for "Disable iAds," install the application, and advertisements will be removed.
Supporting Developers and User Experience
We recognize the importance of supporting developers, and appreciate Nicole’s perspective.
There are instances where ad implementation and user interface design clash, resulting in a frustrating experience.
When a straightforward upgrade path to an ad-free version isn't available, the interface can become significantly impaired. This tip offers a viable workaround in such cases.
Transforming Christmas Lights into Sound-Responsive Party Illumination
A reader, Mark, recently shared an engaging post-holiday hack.
This project is a classic, yet remains highly enjoyable. The period following Christmas presents an excellent opportunity to acquire discounted Christmas lights – my local retailer currently offers a 70% reduction. These lights are remarkably simple to repurpose for new applications. A personal favorite involves connecting the lights to an audio system, allowing the electrical signals powering the speakers to control the lights’ brightness. This creates a dynamic visual accompaniment to your music.
The process of modulating light intensity with audio signals adds a unique element to any sound system.
A link to the original instructional YouTube video is included for those interested in replicating this effect.
A Perfect Addition to Entertainment Systems
Completing the installation of a surround sound system in the basement theater is currently on our agenda. This particular hack appears ideally suited for activating a "Party Mode" within that setup.
The ability to synchronize lighting with audio output enhances the overall entertainment experience.
