Never satisfied until the best. Or something like that. When you've grown up with a die-hard blue-nosed Everton fan, stuff like that tends to stick in your head and pop out at the most inappropriate moments. Perhaps today it's not quite so inappropriate.
After all, the ScoreStore Game Keeping Device (see, it has a name now, thanks to Robot Steve over at BotBuilder.co.uk) is done, finished, working, tested, working, done, finished. But somehow, I feel it's not quite there...
For a start, the LCD display is big and clumsy. Secondly, it needs more than 2xAAA batteries to power it. Thinking about the enclosure - which has yet to be designed - this is going to make the device quite a big heavy thing to carry around in your pocket! A big display I can live with, but having to pump 4 x AAA batteries into something like this seems a bit overkill - a portable CD player or a torch, maybe, but an LCD display with a couple of buttons?
My game score keeping device will end up the size of a C90 cassette tape! It'd be easier to carry an A5 notebook in your pocket - there has to be some way of making the whole thing smaller, lighter, and altogether more "professional" looking.
As it turns out, this little thing appeared on eBay. It's a GLCD (graphical LCD). Look at it - it's tiny. No thicker than an After Eight mint. And, best of all, it runs at 3v (as low as 2.5v, so it still works even after a bit of battery drain!). Brilliant.
Low profile, low voltage, and 4 times bigger than a 16x2 character display.
What's not to love about this GLCD?
Luckily the Oshonsoft PIC18 simulator/compiler supports graphical LCD displays - so the commands currently used for writing data out to the 16x2 LCD can be quickly and easily upgraded to use the GLCD. And, to put the cherry on the cake, we can have some nice icons and monochrome bitmaps, just to show off how clever it all is!
