There are other technologies which are sort of like eink but better, here's one example: It's expensive though. |

I am not a fan of LCDs for instrumentation. Glare, low contrast ratio, low resolution. Give me graphical OLED or VFD for high end, segmented VFD for mid and plain old regular 7 segment LEDs and illuminated indicators (think icons with an LED behind to light up when they're active) for low end. graphical LCDs and segmented LCDs are actually a "feature" point that turn me off of selecting an instrument. |

E-ink would just be a novel(and have obvious problems that are not that easy to solve unless you buy ready-made one, like backlight), LCD is just much better fit for the job --- End quote --- That was not my link or proposition. I'm just somewhat aware of the capabilities of the technology. Again, let's be factual. I don't quite understand the comment about "ready made". LCD would be too, right? The same applies to both technologies. |

Basing a production design on surplus parts is also very risky, unless they are so cheap you can buy a reasonable lifetime's worth of stock. --- End quote --- See, that's a real argument. Power supplies have to be safe. |

Personally I am another advocate for a bar graph or % of set-current display. I also want to have the current shown in mA where appropriate. Here is a craptacular mock-up of a way to shoehorn those features in. |
