From drawing board to reality
Things are moving pretty quickly at Nerd Towers, with our Score Sure Golf Pro gaming device finally making it off the screen and onto the hardware!
Here's a picture of the device in development:
It's not entirely complete: there's something funny going on with the display. When a few characters are displayed, the contrast is nice and sharp and each pixel stands out clearly. As more pixels are lit up, the contrast gets dimmer and dimmer. To the point where if you try to display a bitmap image, the screen appears blank - and only by waving it about do you realise that the image is there, it's just that the contrast is so low, the pixels don't appear to be lit up.
Even during "normal" operation, where rows of text are sent to the screen, pale stripes appear everywhere, where the contrast for an entire column is lower than other parts of the screen.
Perhaps it's because it's one of these low voltage 3v ones.
Maybe there's a reason why most LCDs run off 5v.....
