This board is made to charge from 1 to 6 cells in series and supports a thermister for sensing overheating batteries.<br/><br/>This circuit design is planned to be a part of a pen-like stylus with a camera and haptic feedback for blind people to feel visual art.<br/><br/><a href="https://codeberg.org/bcecoop/bce-pcb-bq25172dsgr">https://codeberg.org/bcecoop/bce-pcb-bq25172dsgr</a><br/><br/>#blind #a11y #accessibility #ee #pcb #fosh #foss #bce #prototype #maker #nimh #battery #charger<br/><br/> <img src="https://gnulinux.social/system/media_attachments/files/115/964/351/921/291/264/original/f1c8b7d59707a7f1.png"> 2026-01-27T01:02:25Z https://njump.me/nevent1qqsq4lugadqk67lthgeu9e3eq0mrdapup3svsmz3249tjfumxwg0lwqzyrkv5swgke2safxr76ap6vr94lz48g9y3kg6008c7lctesmt2m55xakdm6t 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.<br/><br/>This is a step toward our first accessibility product for blind people to feel visual art through a haptic pen-like stylus interface.<br/><br/><a href="https://codeberg.org/bcecoop/bce-pcb-bq25172dsgr">https://codeberg.org/bcecoop/bce-pcb-bq25172dsgr</a><br/><br/>#blind #accessibility #a11y #pcb #prototype #fosh #foss #freehardware #freesoftware #copyleft #ee<br/><br/> <img src="https://gnulinux.social/system/media_attachments/files/115/919/649/675/505/343/original/7a1505d162349a9e.png"> 2026-01-19T03:36:14Z
