Braille Is Your Own Date Embosser
Braille ( , ) is a tactile writing system used by blind or visually impaired people. It can be read either on embossed paper or by using refreshable braille displays that connect to computers and smartphone devices. Braille can be written using a slate and stylus, a braille writer, an electronic braille notetaker or with the use of a computer connected to a braille embosser. For blind readers, braille is an independent writing system, rather than a code of printed orthography. Braille is named after its creator, Louis Braille, a Frenchman who lost his sight as a result of a childhood accident. In 1824, at the age of fifteen, he developed the braille code based on the French alphabet as an improvement on night writing. He published his system, which subsequently included musical notation, in 1829. The second revision, published in 1837, was the first binary form of writing developed in the modern era. Braille characters are formed using a combination of six raised dot ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Braille Printer
A braille embosser is an impact printer that renders text as tactile braille cells. Using braille translation software, a document or digital text can be embossed with relative ease. This makes braille production efficient and cost-effective. Braille translation software may be free and open-sourced or paid. Braille embossers can emboss single-sided or double-sided (called interpoint) and can produce 6- or 8-dot braille. Blind users tend to call other printers "ink printers," to distinguish them from their braille counterparts. This is often the case regardless of the type of printer being discussed (e.g., thermal printers being called "ink printers" even though they use no ink). As with ink printers and presses, embossers range from those intended for consumers to those used by large publishers. The price of embossers increase with the volume of braille it produces . Types The fastest industrial braille embosser is probably the $92,000 Belgian-made NV Interpoint 55, fi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Braigo
Braigo (Brai-lle +Le-go) is a Braille printer design. Braigo version 1.0 uses a Lego Mindstorms EV3 kit, which includes a microprocessor with assorted components such as electric motors, sensors and actuators. Braigo v1.0 was designed by 13-year-old Shubham Banerjee in January 2014, as an entry in 7th grade school science fair project. The model was based on the PLOTT3R, a bonus model released with the EV3 kit and originally designed by Ralph Hempel. The cost was said to be about US$350 or 250 Euros for the Lego Mindstorms EV3 kit and some extra commonly used hardware whereas a conventional Braille printer retails starting from about $1,900. In August 2014, a new company called Braigo Labs Inc. was formed with an office in Palo Alto, California. Since Shubham Banerjee was a minor, his mother Malini is listed as the President of the company and the law firm Inventus Law acting as advisor. On September 9, 2014, at the Intel Developers Forum (IDF 2014), Banerjee demonstrated 'Braig ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

H8 Family
The Hitachi H8 is a large family of 8-bit, 16-bit and 32-bit microcontrollers made by Renesas Technology, originating in the early 1990s within Hitachi Semiconductor. The original design, the H8/300, was an 8-bit processor that had a 16-bit registers and ALU that allowed some 16-bit operations. Two upgraded versions were introduced, the H8/300L that expanded the instructions to become a full 16-bit machine while being optimized for low cost, and the H8/300H which further expanded the registers to allow 32-bit operations and was optimized for low-power/high-performance roles. Many variations exist. The entire line was sold to Renesas in 2003. Renesas continues to sell the designs , but only to existing customers. An administrator on the Renesas user community boards commented in 2011 that there are no plans for further development of H8 based products. H8 was supported in the Linux kernel starting with version 4.2 but support was removed in version 5.19. For higher performanc ...
