How much would you pay for a fully programable thermal computer with a 4x20 Matrix Orbital LCD taht could be bypassed (i.e. controlled by the PC). It will have 8 sencors and 8 Fan channels. With each channel having 4 levels 100%,75%,50%,0% all controlled automatically. Goes beyond any similar porduct currently out there.
sounds like a matrix orbital crossed with a digidoc5 and then added nething else that would make it better um alot?
I want to know how much people are prepared to pay for what darkangel basically said a matrix orbiatal crossed with a beefed up Digidoc. I am planning to producae bettween 10 and 20 of these in a few months in order to make a bit of cash. Hence why I want to know
Sounds like £20-30 worth of 'tronics on top of the cost of the LCD to me... you could probably sell the addon board on its own for a bit more than that I'd say Rob. p.s. where abouts in cambridge are you mate?
About £30 worth of electronics + the LCD is about right however there is a bucket load of programming to do all in ASM (about 2000+ lines) so that is not too easy. I was wondering what people woudl be prepared to buy it for. The only problem with selling the board only will be that it will only work with 20x4 LCDs or else I would have to trotaly reprogram the GUI. I am just of trumpington road.
If you're going to so much trouble why use an MO display? Adding a parallel-serial convertor to your controller won't take that much effort and will bring the cost of the displays down by a lot. Rob.
For 1 the MO display is very high quality and will require no adjustment what so ever. 2) I know how to output to an MO LCD 3) MO LCDs have a very large software base for when you bypass the LCD. 4) Ok lame excuse but it is more electronics on a board that has already 8 transistors and a shed load of resistors + a 64pin IC and more stuff for flashign the IC. 5) If you woudl be kind enough to find a high quality Parrrellel LCD the uses identical input signals to an MO LCD then I would be very interested in transfering over to ap parrellel LCD. (Must be 20x4 and have a nice coloured back ligh)
Well MO just use plain ordinary // lcd units... sure they choose them with good contrast displays and nice backlights but it's easy to do the same. If you just took the easy route and bought from crystalfontz you'd save about 1/2 - 2/3 of your LCD budget. Of course software will be an issue, if you're just making a few then I don't think MO could do anything about you using their command set in a cheeky fashion though. Just seems odd to spend so much time and money to make a grand-daughter board for a bare parallel display and be forced to sell the whole lot for a large amount of money (we're talking in the ball park of £100 - be hard to get a lot of sales at that cost) when you could just skip the middle man. Rob.
looking at Crystal Font's webby chagning to a Parrellel LCD woudl save me some money but as I would have to make a seria to parrellel convertor to power it which woulb be a few pounds and a lot of hassle (not much but a enough) and as this is an A level Tech project that is primarily for myself I think I can cope with spending that bit extra to allow me to use different baud rates e.t.c that I coudl not do if I had to make my own serial-parrellel convertor. Just thinking of selling a few to people as they are far better at reducing fan noice than a DigiDoc and you dont need to adjust the setting like a normal rheobus (and it looks nicer)
Fairly snuff - your call CF are the easy option, I've seen 4x20 // blue LCD's go for $15 and less before now. Rob.
