Talk:Tutorials/Block update detector

I created this page because I felt this information was lacking from the wiki. There is much more info on the topic. Please help expand this page. Smickles 01:22, 23 August 2011 (UTC)

What is a BUD Switch? An introduction paragraph would help, explaining what one is. --HexZyle 19:14, 23 August 2011 (UTC)
 * Thanks for making this page, it was on my list of things to do and it's an important redstone mechanism. I've never seen a rail powered rail style, do you have an image or video?Qcdynamics 23:06, 25 September 2011 (UTC)

Tree growth
In response to this edit: http://www.minecraftwiki.net/index.php?title=Tutorials/Block_update_detector&curid=16349&diff=134098&oldid=134095

BUDs detect tree growth, at least both of the piston-based do. The water-based surely does not, and I don't know for sure why.

Cored's publishing of the discovery
I feel like this should link to the video, rather than the reddit post. Am I wrong here? –The preceding unsigned comment was added by Smickles (Talk . Please sign your posts with
 * My take on videos (and all external links in the tutorial section) is that they are only necessary if the information on the page doesn't (or can't) fully cover the material. Personally, I don't think that video adds anything, although a tutorial on how to build one would be appreciated.
 * I'm also not a huge fan of naming people who 'create' something like this since it is a community and generally not a single person's invention. I'm not saying he didn't create it on his own or anything, it's just not that useful to throw names around like they are the only important figure in the invention. I mean, isn't kiershar's furnace trap essentially a bud switch, albeit with a one time use? Qcdynamics 23:06, 25 September 2011 (UTC)

More information or links needed
The list of things that BUDs can detect contains: "Dirt becoming tilled soil, soil becoming moist, soil reverting to dirt (but this can be more easily detected with a repeater)" The word "repeater" is linked, but there's no information on that page or this one about how a repeater an be used to detect these sorts of things. I think that information should be on this page, as such detection is similar to the function of a BUD switch (and is mentioned). I'd add the information myself, but I'm not sure how one could use a repeater to detect changes in dirt. --67.2.118.57 05:57, 25 December 2011 (UTC)
