Automatic round trip car report based on Launch_pad (program + schematic + PCB)

The MSP430 microcontroller is used as the detection and control core of the car; a photoelectric sensor is used to detect the black belt on the road, and the feedback signal is sent to the MSP430 microcontroller, so that the MPS430 microcontroller controls the car to drive at a predetermined speed in each area according to the predetermined working mode, and The MSP430 microcontroller can control driving in different directions depending on the working mode selected; the Hall element A44E is used to detect the driving speed of the car; the 1602LCD is used to display the driving time of the car in real time. After the car stops driving, the driving time, driving distance and each speed zone of the car are displayed in turn. Travel time. This design has a simple structure and is relatively easy to implement, but it is highly intelligent and humane, and reflects intelligence to a certain extent.

Steno-Flex: An innovative, cheap, customizable shorthand

Steno-Flex is a unique, low-cost stenotype that matches standard stenotype layouts and key actions. By using flexible keys with touch sensors, Steno-Flex is able to simplify the stenotype's design and mechanics, making Steno-Flex lighter and less expensive than current stenotypes on the market. Steno-Flex uses modern materials and electronic equipment, combined with computers, to allow students and novices to develop shorthand skills. Just plug the USB cable into your computer, launch the open source shorthand software Plover, and you're ready to go. Provides online tutorials and guides. Steno-Flex is an effective device for people who want to learn shorthand and develop real-time speech transcription. Shorthand technology is evolving to become the standard solution for data entry, from simple keyboards to sophisticated shorthand controls.
