Re: Affordable Braille Displays: Cost vs Quality
Thanks everyone for taking the time to share your thoughts on this, it's proving to be quite informative, heh.
Wireless systems tend to be unreliable in general, its hard to say if its usually a result of the transmitter being too weak or too much localized EM interference, or both. Like you say though the cost of bluetooth shouldn't be all that much, the Raspberry Pi Zero retails for 5$, while the RasPi Zero W with built in bluetooth and wifi capabilities retails for 10$. Sure its double the price, but the overall cost, especially when you compare it to other RasPi models both with and without wifi which are around 35$ its still relatively cheap. Your thoughts on manual refresh for slow refresh rates also makes sense, it would really suck to have a display suddenly decide to refresh for a few seconds, having control for when it refreshes or not seems like a good quality of life option.
Alright here's another question, some open source electronics like the [OpenBCI] EEG headset retail for around 800$, but you can buy them as a kit of parts that you assemble yourself for 600$, or just the electronics where you have to 3D print the other components and assemble it all yourself for 350$. What if you could buy a braille display as a kit that you assemble yourself, or with some assistance, for such a discount or half price? Is that an option any of you would consider? Lets assume for the moment that there's no soldering or cutting involved, something more like ikea furniture.
As a bonus question, what about being able to customize your braille display? Such as having a custom embossed image on the case, custom shaped case, or braille text? Or how about custom braille pins? Like smooth rounded pins, square pins, rough textured pins, pointy pins, or combinations thereof?
