Just as a cliffhanger for a possible future:

I see a big potential for E-TKT to transform into an accessible open source braile label maker.

Reizen RL350 is a Braille label maker that's pretty much analog to how E-TKT's daisywheel works.

Just think how better the labelling user experience could be for the blind not only by all the features already present in the E-TKT, but also by incorporating voice commands and other things that might be uncovered?

To begin with, I even think that the whole system might be simpler by using a rotating encoder with a 6 pin in matrix instead of a daisy wheel.

Yeah, that's a radical change but lets keep that in mind ;)

That's it for now, let's see what future holds!
