I just received, assembled, and configured the Anavi 12-key Macro Keyboard. There is a python file that shows up on a USB filesystem that appears when the keyboard is plugged in, which is easy to configure to produce any macro keys. I'm using it to control OBS hotkey scripts for live streaming. I highly recommend this keyboard.

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.

Designed a PCB centered around the high current dual op-amp, MC33178DMR2G, taking +14V power input and 0V to +3.3V analog haptic motor control signal input and outputs an AC ±6V haptic drive signal with active single pole high-pass filter with 1.6Hz cutoff and 10x amplification centered around a DC +7V powered center tap. Designed to drive the piezoelectric haptic motor, PHUA3015-30A-21-000.

Just finished a first design for a higher voltage boost converter voltage regulator for a motor power supply for our pen-like stylus for allowing a blind person to feel visual art through a haptic interface. The output voltage of this boost converter can produce any output voltage between 3.3V to 14V and can function with input voltages down to 1.5V.

Just placed an order for a new prototype PCB (Printed Circuit Board) for makers. This one charges NiMH (Nickel-metal Hydride) rechargeable batteries with charging speed options, support for up to 6 cells, temperature sensor, and USB-C plug.

This is a step toward our first accessibility product for blind people to feel visual art through a haptic pen-like stylus interface.
