It's a hobby project in that case, not a commercial one. --- End quote --- Actually this is an EEVBlog project. The revenue from the video discussing the making of the custom LCD will probably cover the cost. I'm looking forward to seeing the video. |

I think that’s a good start. Custom character LCDs really are great for visibility and clarity, especially under variable lighting conditions. Plus they use a lot less power (which may or may not be relevant here.) On the multi-colour backlight front, do remember that there are colourblind people out there. Assuming you’re not running into trouble with segment count, I would suggest the following (most useful to least IMHO): - Error - CP (constant power) - Over currrnt trip - Over voltage trip - Remote - Ohm, kOhm indicators (in case someone wants to make a uLoad) As others have suggested, a bar graph could be nice but isn’t critical. Edit: removed stuff that was already done (I was late to party...) |

It will help legibility and look more polished. --- End quote --- I didn't even notice the kerning problem, it happened in the conversion from vector artwork to png. Weird. --- Quote from: Mr. Scram on October 25, 2017, 01:07:30 am ---That already looks a lot more mature than the previous version. I like the increased legibility of the things in solid blocks. I do notice that the MIN/MAX aren't sized the same on the volt side of things. That should of course be a minor fix. --- End quote --- Yeah that was fixed, forgot to update the section with the MIN/MAX template. Thanks everyone! --- End quote --- From a intuition point, i'd have MAX above MIN (rather than the otherway around) on the display. In fact, i might have: MAX CC MIN to make it even more intuitive |
