If I learn electronics, can I get this idea to work using a breadboard?
You can buy your components from:What are good sources for parts? DigiKey? Newark? Others?
JugglingReferee said:I gave my particulars to a design company and their quote was $10,000 to design the device and produce a prototype.
My device is nothing except a countdown timer, that sits in a box that clips to your belt.
So, I need a power button, a start button, a stop button, a reset button, and a simple LCD display, and a battery of some type (hopefully a AAA or CR2032).
Hi,Chipmunk said:..Or do you have any special requirements regarding power consumption ? How long do you want the battery to last ?
Housing: small plastic case (like a TV wireless microphone transmitter) with belt clip
Power: Either CR2032 or AA or AAA (that can use re-chargable AA or AAA batteries)
Display: LCD (since LED requires much more power), with a minimum of two (2) 7-segment characters, although a 1-line, 16-character display would be nice
Switch:
a) Countdown/Set
Buttons:
a) Power (responds only to holding for 4-seconds, much like the PC power off operation)
b) Start/+
i) Start in Countdown mode
ii) +1 in Set mode
c) Stop/-
i) Stop in Countdown mode
ii) -1 in Set mode
d) Reset Timer 1/Active Timer 1
i) Resets Timer 1 to user-defined value in Countdown mode, and also stops the countdown if it was running when pressed
ii) Sets the display to show the value of countdown timer 1 and change according to + and - buttons
e) Reset Timer 2/Active Timer 2
i) Resets Timer 2 to user-defined value in Countdown mode, and also stops the countdown if it was running when pressed
ii) Sets the display to show the value of countdown timer 2 and change according to + and - buttons
it sounds just like a piece of cake
u can built such device under 6$ if u r in pakistan
