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.

I've gone through @bce 's product purchase process, including product browsing, configuration, adding to cart, viewing cart, and checkout pages to make sure they are accessible to screen reader users. I've replaced all tables with hierarchical headings, and made sure all inputs are labelled. I'm testing with LibreWolf on Debian with Orca. If any blind users out there could test with their setups and have any feedback, it would be greatly appreciated! Thank you!

Note that once this web software is stable, it will be released as FOSS to assist other blind entrepreneurs as well.

New Product:

*2 AAAA Series Battery Holder*

https://bce.center/products/BCE-BHAAAA2S

Hold 2 AAAA batteries in series for your maker project. Have this battery case in a custom color of your choice.

This product is a step toward our future product for allowing a blind person to feel visual art through a haptic stylus pen-like interface.

New Product:

*Boost Converter Voltage Regulator*

https://bce.center/products/BCE-TPS61299YBHR

Take a low voltage battery input and supply one of 21 different regulated voltages for your maker project, including 1.8v, 3.3v, 4.2v, 5v, or 5.5v among others.

We are planning to use this power supply in our future product for blind people to feel visual art through a pen-like stylus haptic interface.
