GlowStitch LEDs – A machine-sewable LED board for adding lights to wearables and crafts (Crowdfunding)

GlowStitch LEDs is an innovative new project that is aimed at making machine-sewable LEDs for wearable tech and special crafts of all forms. The LEDs are made from flexible circuit boards which makes them sewable with a machine and usable for various creative projects by makers, cosplayers, fashion designers, and hobbyists. Until now, sewing LEDs to clothing and soft circuits (e-textiles) had to be done by hand with conductive thread, an arduous process that requires a lot of patience. With the GlowStitch LEDs, creative projects can be prototyped using conductive tape and actualized with a sewing machine. This project has a focus on education and the kit is designed to be used by makers of all skill levels. The LED strips can be machine-washed. However, the maker recommends hand-washing with no tumble dry. The battery should always be removed before washing. Although this is not a kit that requires coding […]

WP-DLC01 USB RGB LED controller supports dynamic lighting (in Windows 11 for now)

WisdPi WP-DLC01 dynamic lighting controller is a small USB board that can drive RGB LED strips and supports the Dynamic Lighting feature just introduced in the latest Windows 11 23H2 release. The board comes with a WisdPi RGB213-5 chip, a button, a USB-C port for control, and a 3-pin header designed to connect an ARGB LED strip which the user can place inside a PC or along a desk or table to personalize the user experience beyond the screen. Right now this works in Windows 11 23H2, but as we’ll see further below it should (eventually) work with other operating systems. The first step is to connect the controller either externally via a USB-C to USB-A/C cable or internally using the 15cm USB 2.0 internal motherboard header to USB Type-C cable provided with the WP-DLC01 board by default. WisdPi also offers a full kit that adds a 1-meter USB 2.0 […]

5V wireless LED lights up thanks to magnetic resonance coupling technology

Wireless power, no matter how inefficient it may be, sounds good and even looks good with the “5V remote wireless power supply LED pack” we feature in this post. It also feels magical with the LEDs lighting up thanks to magnetic resonance coupling technology. The solution comes with a coil as a transmitter and each LED bead also includes a small coil as a receiver. When the two are coupled, energy can be transferred from the transmitter to the receiver through the air, paper, or plastic casing, and the LEDs will light up. The magnetic field intensity in this technology is said to be similar to that of the Earth’s magnetic field, and it will not be harmful to human health and other devices. Specifications: Transmitter Module Input Voltage – 5 V Power – 0.5W (10 LEDs) Transmitting Coil Outer Diameter – 70mm, inner diameter 65mm, thickness 0.5mm Transmitter Board […]
