Thanks for the input and enthusiasm! A few comments and questions and then I gotta get back to hw, lol. 1. idk about the LED, just another(albeit very cheap) thing to implement. I have the code made so it will vibrate the motor to tell you what mode you are in and such, but if you like the LED idea it would be very easy to implement so that depending on the mode you are in the LED is a diff color( I have 2 open outputs on the chip still left over). 2. Of course it needs to reset, lol, I have it setup to do so already 3. Dont worry about size, the chip and motor are very tiny and the chip should be able to be run off of a button cell 4. Instead of a stop/start button I was going to set it up so there was a very light switch that made it so that the chip was only running/had power when the watch was on and it the switch was pressed against your wrist(this would also save power and allow people to easily disable it for tests just by taking it off). 5. Do you really think the time intervals should be reset every time it is turned off? what if the user finds and interval they like and then forget it? Right now I have it so your values are permanently saved in eeprom on board the chip so it is remembered even when no power is applied(still can be changed whenever you want though, of course). 6. do you think 5sec is a short enough alert? I wasnt sure how short and long to make the pauses possible for.
Thanks, Im really enjoying working on this!..though we will have to wait till after christmas for me to have all the parts to begin making a prototype
EDIT: I actually really liked the idea of an LED indicator, so I went ahead and implemented it in the code and schematics Ive got. So now, along with the motor vibrating shortly to say u have entered a mode, the LEDs work as follows: LED1 is lit when in the change alertwait mode and LED2 is lit when in alertlength mode; no LED is lit during the normal alert cycle/not in a mode. This can turn out espescially cool if you use bicolor LEDs, I have some tricolor LEDs laying around and Ill probably just use 2 of their colors for this
