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 […]

STMicro VD55G1 – A small, low-power global shutter I3C camera sensor for computer vision

STMicro VD55G1 global shutter camera sensor

STMicro VD55G1 is a new global shutter I3C camera sensor with a small die size of 2.7 x 2.2 mm, 804 x 704 pixels native resolution, and consuming about 1mW in its ‘always-on’ autonomous mode to wake up the host when motion is detected. Camera sensors are available with rolling or global shutter, with most from the former type, but as we’ve seen in our reviews of the e-Con Systems See3CAM_24CUG (USB 3.1) and the Raspberry Pi Global Shutter (MIPI CSI) global shutter cameras, the latter is much better we capturing moving objects clearly at high frame rates with fewer artifacts than with rolling cameras. The VD55G1 global shutter sensor will also benefit from the same advantage but is offered in a smaller package working over MIPI CSI and/or I3C, making it suitable for devices with small batteries used in applications such as eye tracking or motion estimation. STMicro VD55G1 […]

MediaTek unveils 5G RedCap solutions: M60 5G modem and T300 Arm Cortex-A35 SoC

MediaTek has introduced its first 5G RedCap solutions with the M60 5G modem and the MediaTek T300 Arm Cortex-A35 SoC design to bring 5G-NR to wearables, light-weight AR devices, IoT modules, and consumer and industrial Edge AI devices. 5G RedCap (Reduced Capability), part of 3GPP Release 17, aims to keep some 5G features such as low latency, low power consumption, enhanced security, and network slicing while limiting the bandwidth (to around 85 Mbps) in order to be used in IoT devices and products that may not need the bandwidth required by smartphones and computers, but would benefit from longer battery life and a smaller footprint. MediaTek claims to be the first company to unveil 5G RedCap chips with the M60 modem and T300 SoC. MediaTek M60 key features and specifications: 3GPP Release 17 standard 5G modem R17 UE power saving R17 Coverage enhancement R17 Small data transmission LTE & NR-FR1 […]
