Talk:Redstone circuits

Bat based RNGs
I was thinking of doing some further research into RNG circuits made with bats in minecarts, but wasn't sure where to put that information. obviously the premise is simple - have a bat in a minecart over some detector rails - but where should that information go?

 * Random number generators? They're currently in Redstone Circuits/Other. --Munin295 04:37, 25 November 2012 (UTC)


 * Thanks. I recall that being on this page and was wondering where it had gone. There should probably be a link to there somewhere on this page, perhaps alongside the advanced circuits page in the see also section. Firebastard 05:43, 25 November 2012 (UTC)


 * Randomizers (of which RNGs are a significant subset) are listed as a topic under "Other advanced circuits", and that section already includes a link to Redstone Circuits/Other. It is all the way at the bottom of the page, so it might be hard to find, but then again it's a much more obscure topic than the other circuits above it. I'll try to work the phrase "random number generator (RNG)" in there somewhere (sometime; or you can), since that is a phrase one might search for. --Munin295 06:50, 25 November 2012 (UTC)

More targeted tutorials
I'd like to see some plans for more complex but practical systems, such as:
 * You have a rail loop (that is, a station) with two exits. You want to be able to:
 * open the loop at either T junction with a button, but...
 * also have the loop re-closed when a new train comes in, so it doesn't just head onward to the next station. An alternative would be to have it stay open for a few seconds, long enough to feed a Powered Minecart and have it push two or three carts out of the station.

So far, I've managed to get a D flip-flop with a detector rail (on the far side of the loop :- going to the clock, and the button going to both the clock and the data. I had to put two extra repeaters protecting the clock line, and I'm still not sure why.  This sort of thing should be a "solved problem" by now, and I'm not wild about having to reinvent it. --Mental Mouse 16:58, 5 December 2012 (UTC)
 * So you're saying we need complicated but practical circuits? I might be able to help. I have a working 4 digit keypad, very customizable. Buttons must be pushed in a certain order. With the addition of the Latch though I may be able to make it more practical, because it takes up a fairly large space. But if you push the wrong button, or push them out of order, the circuit resets and you need to start over. I'm working on a display that functions for it, but it requires so much it would be very impractical. Without the display though it's pretty useful. Not sure if there are designs already for it, but it can be make to have as many inputs as desired (as many correct buttons and in any order). Maybe I can provide a few screenshots of my first successful attempt on it, it is only tall because i thought i would need alot of space, so i used worldedit to make a large platform. #trigger_hurt (I 18:15, 5 December 2012 (UTC)
 * I have made several different circuits without tutorials, and can make most of those circuits I know in minutes, if not seconds, including the keypad. Something else I made that is so compact that you could almost install it into a regular home, is a hidden lavaplace entrance. There are others now, but mine has the wall which I have not seen in any of the other videos I've seen. #trigger_hurt (I 19:42, 5 December 2012 (UTC)
 * I'm less concerned with keypads and similar circuits than with all the little ways in which redstone can be useful... if you can figure out a circuit that does what you want without sprawling over half the countryside. Traffic management for minecarts is a biggie (and I'm about to try a pulse extender instead of my prior solution above), but even things like making a Redstone Lamp blink (but compactly, because it's atop a pillar) would be good, or a prefab clock with period over a few seconds (including describing the adjustments to make it longer or shorter). --Mental Mouse 23:31, 5 December 2012 (UTC)
 * Also: tips for compact crossovers!
