Congratulations to the ten selected projects for receiving 500 US dollars and continue to advance to the 2021 Hackaday Prize finals!Each is a different view Reimagine supporting technical challenges Seek ways to make great hardware ideas serve more people.
E-books make it possible to have a library in everyone’s pocket, including the visually impaired, because text-to-speech can read printed text.But this is not a complete substitute for reading by yourself, so Thenar becomes an affordable and portable Braille e-book readerIt uses a single Braille cell on the edge of the device and a tank track roller for user input.

Okay, quick quiz; how many of us want everything to be powered by solar energy in the future? Most of us have raised our hands now, but how many of us can set up an efficient solar charge controller by ourselves? If the next finalist (pictured above) gets his wish, the answer will be almost everyone. 2.5 kW solar generator in a sturdy briefcase Up to 160 (!) 18650 lithium batteries are being packed. The designed charging side handles Maximum Power Point Tracking (MPPT), while the discharging side protects users through circuit breakers and various regulated outputs (such as 120 V, 24 V, 12 V, and of course all USB)-C function you expect from this system.
