WIP: Timeline of Bristol Braille Development
- First prototype machine: Rotating disc of Braille.
Second prototype: Ticker tape embosser.
Worked with N Krishnaswamy and Keith Shaw to help NK develop the Natesan Display: Single line, Natesan Disc based, serial actuation from carriage head.
Moved into Pervasive Media Studio to continue development.
Third prototype: Dot matrix printer based, serial actuation from carriage head.
First General Meeting in January.
Founded Bristol Braille Technology CIC in February.
Fourth prototype: single cell, per dot shape memory alloy actuation.
Moved to shared office with Fear of Fiction, Clare St.
Fifth prototype: two cell, parallel shuttle and per dot solenoid locking.
First Quixote prototype: single line, parallel actuating, slider-encoder, parallel shuttle, per half cell solenoid locking.
Second Quixote prototype.
Attended World Blind Union’s Braille 21 conference at Leipzig.
Third Quixote prototype.
Moved to Bristol Hackspace.
Quixote development continued by third party.
First Canute prototype: three cell on one line, double size cells, multiline-capable, rotor-encoder, parallel stepper motor driven line, per half cell solenoid lock.
Second Canute prototype: two cells by one line, normal size cells.
Fourth Quixote prototype developed by third party: 32 cells by one line.
Quixote indefinitely post-poned.
First Midas prototype: pseudo-Braille, one cell, glove mounted, vibration actuation.
Third Canute prototype.
For Canute demonstrations since 2014 see demos.
Fourth Canute prototype: twelve cells by one line.
Second Midas prototype.
Midas spun off to be developed by sister company, Babel Technology CIC.
Fifth Canute prototype: 48 cells by four lines.
Third Midas prototype.
Braillists becomes independent of BBT.
Sixth Canute prototype: 112 cells by four lines, stand-alone e-reader functionality, PEF compatibility, 2 built.
Midas development indefinitely postponed.
Seventh Canute prototype: 512 cells by 16 lines, per line refresh by DC motors, parallel per half cell actuation by stepper motor.
For publications since 2016 see publications.
Eighth Canute prototype: 256 cells by 8 lines, encoded Natesan Disc, display only (not stand-alone).
Ninth Canute prototype: 256 cells by 8 lines, stand-alone e-reader.
Tenth Canute prototype: 360 cells by 9 lines, BRF compatibility.
Eleventh Canute prototype: 360 cells by 9 lines, 2 built.
Twelth Canute prototype: 360 cells by 9 lines, reduced size to 1/5th (7.5“x14”x1.7“).
- Thirteenth Canute prototype: TBA…
