r/Braille•

Does anyone have a recommendation? I'm looking for cards with short stories (or similar) to practice as I learn braille.

Ideally looking for a set of both level 1 and level 2.

Must ship to Canada

Is there anywhere that sells tiny SMD solenoids that have <2.5mm spacing? I want them to be as strong of magnets as possible.

I've looked at 0805 inductors, but haven't had luck with them because the shielding used on them is too magnetic, and blocks the magnetic field. The case itself is also magnetic, so I can't attract/repell tiny magnets because they always just stick to the case.

I'm exploring actuation methods for a refreshable braille display as a side-project. Thanks for any advice!

How do I export Google Maps Timeline data now in 2024? It seems that they switched it up so that it's not stored in the same normal format online, but rather in some encrypted format, with the keys mostly linked to phones/devices.

Google Takeout doesn't appear to actually export the location history.

Is there a way to export it? I'm looking for a CSV/JSON/GeoJSON/Shapefile/similar format.

I want to buy a trackpoint (the mouse-control device in the middle of Lenovo Thinkpad keyboards, which looks like it's from the 90s) for a custom mechanical keyboard I'm designing.

I thought about taking one from an old keyboard, but I'm trying to avoid doing that so that I can assemble multiple of the exact design without having to reverse-engineer each trackpoint from each laptop.

Any advice on finding these little guys on Digikey/Mouser/LCSC/any other major supplier? I'm not having any luck with the usual search techniques

What haptic feedback modules are most similar in quality to Apple's haptic feedback devices?

I'm looking to buy a small module from Digikey or similar for a keyboard/trackpad project I'm working on.

I've seen lots of "eccentric rotating mass" (ERM) devices, but I don't see any of them coming close to the quality of Apple's iPhone and Mac feedback (especially the hammer-like abrupt feedback).
