Designed a PCB (Printed Circuit Board) for prototyping the ADXL343BCCZ-RL7, a 3x5mm 3-axis accelerometer with 13-bits per axis at 1.6kHz resolution with ±16g range and 3.9mg sensitivity.

We plan to use this accelerometer in a pen-like stylus for enabling a blind person to feel visual art through a haptic interface.

Just designed a 3D printed lens system holder for a 6.5x6.5mm lens system that frames the 120Hz SVGA CMOS camera sensor (NOIP1SE0480A). This lens system is planned to be at the tip of a pen-like stylus for a blind person to feel visual art through a haptic interface.

Just designed a new prototyping PCB (Printed Circuit Board) for this 3x3mm chip. which converts USB to UART for interfacing with microcontrollers and FPGAs and can also be used for other serial interface needs.

We plan to use this USB to UART controller to interface with a RISC-V microcontroller in our design for a pen-like stylus haptic accessibility product for a blind person to feel visual art.

We've received a first prototype of an 8mm by 8mm LED (Light Emitting Diode) light ring for a small camera. This ring includes 8 LEDs and is powered by an external 3.3V power supply.

We plan to use this light ring in our design for a pen-like stylus haptic accessibility product for a blind person to feel visual art.
