Hi, I'm trying to create a simple pop-up timer for a science experiment but don't really know where to start.
**broken link removed**
My idea is basically for a small timer that retracts after a set countdown.
It's for pushing an external button for a very precise amount of time. I want to be able to control the countdown to within a hundredth of a second and to be able to reset it easily. If there was a way to put the timings into memory (like in a calculator) that would be ideal.
How it would work is, I set the time in the timer, and push the trigger button down onto a button which starts the countdown. When the countdown is finished the arm extension would pop-in, disengaging the external button.
The design does not need to be as above, but I would like it to be small and able to fit in and be worked with one hand.
Is this something that could be done by an amateur like myself or would it take considerably more skill? If it's the former, can someone give me some advice on where I can get started?
Does a timer like this already exist? If there is I might prefer to just use that.
