ysobelI am trying redstone circuitry.
...it is not going well. /rubs at head/
Project A is -- I have a pressure plate in my basement that opens a Door To Mining Stuffs. It is a wooden door, because I have, er, issues, with punching a button and then also getting through the door before it closes. (Not that iron doors need buttons per se, but any sort of input device either doesn't keep mobs out in case some skeletons get loose downstairs, or is a pita for me to use.
On the inside, I have a pressure plate directly inside the door. In theory, this is so that the door will open when I want to go through it (from my basement), and close behind me, and when I go through the other way will, after a short delay, close. It automates the process for pretty much everything except opening the door from outside.
In practice, since the basement is also where I Store Shit, I end up tripping over the pressure plate. A lot. Which is more of an annoyance than a safety issue since I haven't actually seen mobs on the mining-stuffs staircase, but I still would rather get rid of it.
The obvious-to-me solution is to have a lever that will combine into an AND gate: if the lever is off, the pressure plate does nothing; if the lever is on, the pressure plate operates as it normally does.
This is fairly easy in concept. Execution? Not so much.
I have a creative-mode sandbox world up that I'm trying to do mockups in before I "commit" any survival-mode resources. I can get an AND gate to work. (Usually. Right now I can't get a pressure plate to light up adjacent redstone wiring, let alone function as part of a gate.) So I tried making a mockup of my basement, to try to figure something out that would work but not get in my way.
I can set up a circuit with redstone wire leading from the pressure plate (not adjacent to the door) through a gap in the wall to the AND gate setup, and a lever nearby on the wall toggling redstone wire in the gap beneath it, and the functionality of the AND gate set behind the wall so most of it isn't in the way of basement activities, and except for the current issues with the pressure plate, I can get a proper AND gate going, powering wire that leads in a tunnel around the corner to the door.
Or, in bad ascii artwork:
where C = cobblestone wall of basement; D is the door to stairs; A is the gap for the redstone input from pressure plate P; B is the gap for the redstone input from lever L; G is the AND gate (which is several blocks and some torches and stuff, not really relevant; and - - - - and | are the two directions of redstone wiring.
That didn't help much, but, uh, it amused me?
I can't for the life of me get the redstone wire that is output from the AND gate, to power the door.

Project B is some sort of automated wheat farm thing, just so I can have an easily renewable source of foodz. Which I figure will be some sort of arrangement with running water trough next to tilled land next to sticky pistons (on the level of the wheat, not the dirt blocks) with redstone wire threading through the sticky pistons and then connecting to a button or somesuch, so that all I have to do is flip the lever and the crops will kathunk and drift into a collection spot. Granted, I still would have to go back through and manually replant seeds, but it'll save the wheat-punching, right?
...even with watching a bunch of tutorial youtube videos, I can't figure it out.

There are all these videos of people doing amazing shit -- clocks, timers, elevators, etc.
I can't even figure out a basic redstone circuit.
I am this close to deciding it is too hard and giving up.

Date: 2012-02-29 02:41 pm (UTC)Anyway, as far as I can tell, the problem is that redstone wire running parallel to something will not power it, whereas redstone wire running directly into something will. So, instead of:
you need:
Because Notch hates us. And wants us to suffer.
An interesting corollary is that if you put an extra piece of redstone wire in the gap in the working circuit, it suddenly stops working. Instead of seeing this as three wires going into the wall/door, the game sees it as two wires parallel to the wall, with some crossover, but none of it actually going into the wall/door.
This is a problem when it comes to pistons, where you'll be wanting to power a bunch of adjacent pistons. You can get around it by using redstone repeaters, thus:
(where r is a repeater and p is a piston.)
Apparently, the thing with redstone wires not powering things they run adjacent to which applies to doors and pistons doesn't apply to repeaters. You know why this is. It's because Notch hates us and wants us to suffer.
