This must be east...90-degree turn-pause-turn-pause-etc

Archive: 9 posts


EDIT: Grrrr, Title should say "Easy"


Thanks to excitement due to LBP3, I'm trying to get back into creating...but I feel dumb.

The logic should be simple. I have a cross(A "+"). I need it to turn counter clockwise quickly (.5 seconds-ish), exactly 90 -degrees. Then pause for a set amount of time (2-5 seconds, haven't decided) then do it again, continuously. Always the same direction. Turn, pause, turn pause, etc. There are other things that will be happening in there, but that's the part I can't figure out.

I've come up with some ham fisted ideas that kinda work involving the selector and tags, but it's completely inconsistent.

Can you fine folks help? Am I missing a simple tool here?

First. A "Selector" with 4 outputs. A timer with the output connected to the "Cycle" input of the "Selector" and to it's own "Reset" input. 4 "Gyroscopes", first pointing up with the first "Selector" output connected, second pointing right with the second output connected, third pointing down with the third output connected and the fourth pointing left with the last output of the "Selector" connected. Just in case you don't fully understand I've uploaded an image as what you will need to do. Remember the "Microchip" needs to be in the middle of the object.

Hi Biv.
You could use gyroscopes.
Start by locating the centre of the cross that you wish to turn and in the centre place a microchip.
On this place a sequencer set to play forward and loop. The strips per second will set the speed of the sequence.
Set The sequencers length to 8 bars and place 4 gyroscopes(for rotating and pausing times... So it would be-- 1.rotate 90deg, 2.pause, 3.rotate 90deg., 4.pause, 5.rotate 90deg., 6.pause, 7.rotate 90deg., 8.pause ).

In other words... On the 8 bar sequencer, place like this..
BAR 1- 90deg 100% GYROSCOPE...BAR 2 -NOTHING....BAR 3- 90deg 100% GYRO...BAR 4- NOTHING.... and so on until you have 4 gyros and 4 spaces.

HOW IT WORKS...
On the microchip have something trigger the sequencer, (a switch, a battery, a timer?, anything).
When the sequencer activates it starts playing forward, at a desired speed.
As it does it firstly plays bar 1 and rotates the cross 90 degrees anticlockwise (set by you)
It plays on over bar 2, which is just a space, so will do nothing. This will give you a pause.
Next it passes bar 3, another 90degree gyroscope, rotating it a further 90 degrees anticlockwise.
Next, it passes bar 4, another empty space which pauses it before the next turn....
And so on, with 4 turns and 4 pauses.
As it reaches the end it will loop back to the start.
When building it, use the 90 degree angle settings on grid options to keep it squared off.
This should work fine,
But, I'd be happy to make and send it to you if you need my friend

Thank you both!!!

And thanks for the offer Sean. I'm going to see about figuring it out on my own based on the info you two gave me.

Gyroscopes, of course. *slaps forehead*

Thanks again!!!!

HI Biv.
I actually explained it slightly wrong, I apologise.
You wont be able to place the gyroscopes on the actual sequencer, so instead, place the 4 rotated gyroscopes on the actual chipboard, and where they were, place 4 100% batterys. Wire each battery in order into each gyroscope. This will work for you.
Also if the cross is not bolted in the centre to the background, you could place an antigrav on the central chipboard (set to 100 antigrav, 99 dampening)
Sorry for the oversight buddy.

It's good. Once you said "gyroscopes" and "sequencer" I mostly skimmed as the rest of the steps clicked into place anyway.

I think the wobble bolt has a positional input on it. I'm not sure. If it does you could just change the analog signal strength to match your four stopping points. 25 50 75 and 100%. Batteries on a sequencer would work.

Edit; I just tested this. The wobble bolt only works for 1 360? rotation then it winds back to reset.

But a joystick rotator works awesome. 4 batteries on a sequencer going through two signal combiners to a single joystick rotator.

You could just use a rotator. I think the speed is in degrees per second. To do 90 degrees, trigger a basic rotator at 180 speed for half a second like you said. Have a sequencer that loops do this. Immediately following the rotator on the sequencer put a 100% dampening grav tweaker to give it perfect deceleration. Space out the rest of the sequencer so that it is timed properly ( ID have each bar be one second and have 3-6 bars as needed) .

The other methods will get the job done, but here's a different take on it that could work if you want it localized. For example, if the object doesn't start pointing the direction of the first gyroscope as mentioned above, you could use this method instead.

I think I settled on Tynz method. (Thanks, BTW) Seems the most stable so far. Sean's method worked well, but used a lot more "parts."

Now, if I can get the rest of it to behave. You folks may be hearing from me again soon.
