maybe i can hack a cheap mouse and use it for my touchscreen project.it would make it cheaper.but still,avr would be available for around rs200,extra components for 50-100 rupees,which is still not very expensive.
hey,i saw a page where it was written that you can use arduino for programming avr mcu's.does anyone know how to do it?h
Ok so you want to run pointer on that LCD with the use of an mouse , you can then use the ATTiny(im not getting this in india at the online stores and not even in wholesale market rather than a 12F683 is heavily available) i misunderstood you , i thought you did want to build it for manufacturing , for studying and development you do take up what GoForSmoke is telling you.and you can take input co=ordinates from the attiny programmed and then show it on the LCD.
Or just study and implement the PS/2 communication protocol for HID instruments and you can implement that in either mouse or keyboard input.
i am going for manufacturing(kind of,you know,if it works good).and i am going to need atmega8,because i need more inputs.moreover,it is cheaper than attiny(i think).the manufacturing cost would be like rs300,as the cost of atmega would be around 200,and the sensors and basic components around 100.then i will build board(as shown in v-usb examples),program it to take values from sensors and react accordingly,and control the mouse pointer.what do you think?
You can give it a try.
I look at Mouser.com (electronics seller) and click Change Country to India and ATtiny85 through hole DIP is $1.62 for just one and $1.30 ea for 25, $1.29 ea for 100. They have 19 locations worldwide (home in Texas) so I don't what the shipping is.
In parts of this country we have entire valleys filled with trash, or very big hills and ranges of hills made of trash (I have seen one that goes for miles back in 1985 in New Jersey, the Amtrack trains run along one edge) and much of it is due to the word 'disposable'. We have places where the trash is covered over with dirt and people and houses on top.
If you have any way to even slow that from becoming normal in India then one human to another; save your country!
Talk around, see what you can do. Nobody makes a repairable mouse. I see no mouse with buttons that don't wear out so they need "throw it out and get another". Light beam interrupt or a touch sense or another way would be better, and touch sense should cost less to make than mechanical button.
The corporate thinking is to sell what must be replaced so they make and sell over and over. But if someone is first for a cheap long lasting or self repairable item, it could catch on to a market too big to fill soon. By then, be ready with another product! If you are small then maybe you get started before the big companies notice. Once they do though, watch out. It will take them longer in meetings to change their minds and ways than to copy what you do. If you get a good one then perhaps the best would be to sell the design and move to the next thing.
yeah...you are right.my circuit is very simple,when compared to the circuits of other mice,and can easily be repaired by anyone with basic knowledge of soldering.it has no mechanical parts as such,and can be repaired very easily.so,it's not bad,is it?
Nobody has the time to repair a cheap item nor all have any solder iron at their place or are willing to take it up, all are not developer minds out their leaving some who would like to explore into the system to know what's wrong with it also please move the end user which could be a manager,etc. They will not leave their job to repair a very cheap item.
All im emphasising is that lotw your end customer mindset, do some surveys know the market them get on something .
sure...i will start right away asking people.....what about internet?any sites you know of?besides,what exactly should i ask?
Try asking friends ,relatives and on internet Facebook will come to somewhat useful value:
- Ask them about what they think about easily repairable mouse and,
- what they think that how much they can spent over a mouse ? and,
- What time period they expect the mouse to work for?
It would depend on what would even need repair or replacement and how it is to be done. The only parts of my mice that need fixed are the dang buttons but perhaps after that the light source would go next. Led hours run 50,000 to 80,000? That is enough to not worry, 24 hrs x 365.25 days = 8,735 hours per year. At 12 hours per day it will be more than 10 years to expected failure. Microswitch or cheaper buttons fail in a fraction of that.
I can make a beam interrupt out of 2 leds and 2 resistors or 1 led, 1 detector, 2 resistors -- either way using 2 digital I/O pins. What might wear out would be the -shell- with the part that bends or hinges to allow movement. Repair could be to change the shell or part of it.
Solder is not the only acceptable electric fastener. Ever seat a chip in a socket?
I also like the accelerometer mouse but they're not cheap.

Only a Accelerometer itself costs about 11 USD but would be a nice development. 
mouse would be nice,how about a touchscreen?and that too not a normal one,an overlay kit,with which you can turn your computer into a touchscreen computer for rs500?by the way, @NI$HANT i found a site bricsworld.com which sells everything cheap.is it reliable,because it looks suspicious
i can't tell only by the site that if its that useful or not because i haven;t ordered anything from this place.
which you can turn your computer into a touchscreen computer for rs500?
Man.....you are getting all over the place ,Do not take ill of my words , im suggesting you in this way because you have go step by step , first learn using the LCD like a GLCD and then after it learn how to make that small GLCD a touch screen LCD then onto from here move to make A REALLY BIG! pc screen a touch screen, step firmly not all over the place but on one pathway achieve one thing then strive onto further thing,
understand what you want to be actually A Business man first or a Developer/Engg. ? if a Business man then you can take up any Developer/Engg. and pay him to develop things to make money out of and if your want to be a Developer/Engg. then you have to understnad the Nobleness and Intricacies of this field.
no no no....you've gotten me all wrong.actually,this is what i am going to do.
users will stick two sensors on their monitor's bottom left and bottom right corners.the sensors will sense the position and give the info to the main circuit.this circuit will be an HID and will change the position of mouse cursor and clicks accordingly.now the cost for production will be cost of atmega+50rs or +60rs max.cost of packaging,i dont know but still, must not be more than 40 rs.even if atmega is 200rs,then total cost price is 300rs.selling price is 500rs so,rs200 pure profit. ]
i am the developer kind of person,not a businessman type.any guides?
Nickity. I´m Sure You deserve that title; that´s how ANY question , how ever STUPID, should be answered. That doesn´t mean that the rest of you don´t help, but you COULD some more.
Thanks, to ALL of You.
