QJ Timer, More Accurate/Precise than SS Timer???

Wouldn't the only real way to test if they are accurate to each other is by starting and stopping them at the same time? One might ask how to do that...

Stefan posted an "Inside the Stackmat" thread a couple weeks ago or something. Just start the timer by using switches hooked to both at the same time.

If you plan on using the "I'll just put my hands on both of them" that would be invalid because there would be no proof you actually hit both of them at the exact same moment.

Robot rig :3

It'd be much easier to just take two toggle switches, wire one to the left side of both timers, wire the other one to the right side of both timers, then flip the switches. All you have to do is flip one switch, flip the other, then flip it again, wait however long you want, and flip it again.

If the timers don't agree on the time, one of them is wrong! It would actually be really interesting to do this to say 10 stackmat timers at a time.

New idea for the next comp maybe? Lol

You are saying that the QJ timer is precise, yes, but just to let you know that it's a different story from being accurate.

A timer may be able to record up to thousandth of a second, but each second may be 3 seconds for the clock. If you are to prove that the timer is accurate, you'll need to verify it with an atomic ****.

Daniel your word after atomic was censored from the forum settings. I'm guessing it was to be something that goes boom and creates a big cloud of fire and smoke and is pretty lethal? If so, that wouldn't prove it's accuracy, only the accuracy of the builder of that such device that was mentioned (when you build those it's wire lengths and other things that count, not the actual detonation timer).

Does anybody here have both a stackmat and QJ timer?

WTF? why is the word "c-l-o-c-k" censored???????

this forums' weird :fp

Clock.

What??? lemme trry again:

Atomic clock

That's odd. When I first read your paragraph I thought you meant clock, but then I realized the asterisks probably weren't put there from you, and thought of the next best thing that would be censored and also need some sort of accurate timing.

Anyway, I completely agree with you, we'll need to measure it with an atomic clock. The problem is...how will we be able to do that? I don't know enough about atomic clocks (other than they use microwaves or something from energy) to know if we can actually start and stop an atomic clock?

I know it wasnt clear but when i posted accurate/precise i meant individually.
I know that measurements that start at 0.01 and increase by 0.01 is more precise than a timer that starts on 0.02 and increases by 0.02, but as i dont own a stackmat, do they count in 0.02's or just thats the earliest it can stop?

I think that he may have perhaps forgotten about the "l" in clock.
