DigiKey - Sharper Image [Maker Update] | Maker.io
The video highlights several DIY projects showcasing creativity and technical skills. The first project involves creating a high-contrast television by combining an LCD panel from a salvaged TV with a projector, achieving dynamic backlighting and improved contrast. This project demonstrates the potential of repurposing old technology for enhanced performance. Another project focuses on making a DIY skincare mask using red LEDs, offering a cost-effective alternative to expensive commercial products. This project emphasizes understanding the science behind red light therapy and applying it practically. Additionally, a 3D printed game simulates logistics in the solar system, showcasing iterative design and problem-solving. An all-terrain skateboard with tank treads is also featured, highlighting the challenges and learning experiences in DIY engineering. Lastly, a gesture sensor developed by Corebb offers a novel approach to integrating gesture control into projects without visible sensors, enhancing design flexibility.

2. š¬ Introduction and Project of the Week
- The segment introduces the Maker Update show, a platform to explore innovative projects by Makers.
- Hosted by Tyler Winegarner, the episode aims to inspire viewers while keeping them informed about the latest in the Maker community.
- The introduction sets an enthusiastic tone for the 'Project of the Week,' encouraging engagement and anticipation.
3. šŗ DIY High-Contrast TV
- DIY Perks is enhancing TV contrast using old TV parts to approximate modern OLED displays.
- LCD panels' contrast limitations stem from backlights that cannot be fully blocked, leading to washed-out dark areas.
- Manufacturers use selective backlight illumination to improve contrast, which can result in a blooming effect.
- The project uses a salvaged LCD panel without its backlight, paired with a projector for dynamic backlighting, enhancing contrast.
- Aligning the projector with the LCD panel poses challenges like ghosting, but this method shows promise.
- Key innovations include removing the projector's color wheel for increased light output and using OBS software's Luma Key filter to enhance specific contrast areas.
- Image projection through mirrors allows closer wall placement, increasing practicality.
- While not fully matching modern OLEDs, this DIY approach significantly boosts contrast using repurposed materials.
- Step-by-step alignment involves meticulous calibration to prevent ghosting and achieve optimal image quality.
- Challenges include managing projector heat and ensuring proper image processing to maintain color accuracy.
4. š” DIY Skincare Welding Mask
- The project was a collaboration between Ruth Amos, Michelle (LabMuffin), and Becky Stern to create an affordable DIY red light therapy mask.
- The main goal was to explore the science behind red light skincare therapy and perform an electronics teardown of existing devices.
- Ruth Amos aimed to produce a cost-effective alternative to commercial red light masks, which typically cost around $400.
- The DIY version was made using a welding hood and LEDs, significantly reducing the cost while maintaining potential effectiveness.
- The project involved identifying the ideal wavelength for efficacy and applying this knowledge in a budget-friendly manner.

- The gesture sensor by Corebb is designed for high sensitivity and can be completely hidden, unlike traditional optical sensors that require visibility.
- It features a large PCB with high precision in detecting hand movements and communicates over i2c, making it easy to integrate into various projects.
- Corebb has made all sensor details available on GitHub, allowing developers easy access to the technology.
- Adafruit's Sparkle Motion boards offer extensive control over addressable LEDs, with pre-programmed controllers compatible with WLED software.
- There are three versions of Sparkle Motion boards: a mini version and two full-sized versions, each with different antenna configurations.
- The full-sized Sparkle Motion boards support xLights software, enabling LED pattern sequencing and music synchronization.
- Sparkle Motion boards are praised for their robust build, comprehensive documentation, and affordability.
9. š Understanding Brushless DC Motors
- Brushless motors operate longer and require lower maintenance than brushed motors due to fewer parts that can wear out, such as brushes and commutators.
- They are quieter due to their construction, which eliminates friction noise typically found in brushed motors.
- The design complexity of brushless motors is higher, necessitating internal hall effect sensors to determine motor position and an external controller for operation.
- Applications of brushless motors include electric vehicles, drones, and industrial machinery, where efficiency and reliability are critical.
- While the initial cost is higher, the long-term savings on maintenance and improved performance make brushless motors a preferred choice in many high-demand applications.
- Brushless motors offer higher efficiency and better performance metrics, such as torque and speed control, compared to brushed motors.
