To all the redstone people out there

On my way.. -Fixed

lol thanks so when i put string down do i have to have a tripwire somewhere?

Not to my knowledge. I personally use redstone; but I'd assume string alone would work.

I'm thinking if you added a tripwire on the end, it might lay down the string for it to work. Not sure.

I might be late to this thread But, I have designed in the past ones that only turn on when all redstone is placed down - and doesn't turn off until all redstone is turned into obsidian.

The one that I designed leaves a perfect gap in between two pulses, so the lava is only in front of the dispenser long enough to form obsidian and then goes back. I might look into making a design on SP which makes sure there's redstone though. Powering it with a torch isn't a bad idea

I do have one question...could i expand it?

Yep. but I'd need to redesign it since I put the input system on the right side and edge of your residence is on the left.

Also, I just hopped into SP and successfully made a design that will quickly make sure that all your redstone is placed down (to prevent lava leakage) and it's also super compact. I may make a youtube video on it later

well could you change mine into that design? also make it longer?

I don't know why you'd want it any longer.. and also if you want it longer than 13 dispensers than it'd take extra repeaters and redstone. The new design replaces the button and adds a monostable circuit as well. You're better off basically destroying the one I made you.. Not worth trying to upgrade it.

Don't apologize, it is a great idea
