As observers can detect the state of other observers, placing two adjacent observers, each watching the other, can make a fast and compact redstone clock….Limitations.

Can you change the color of a beacon without glass?
[NOTE i: Plain glass will not change the color of the Beacon. White will also not change it unless it’s combined with another color.] [NOTE ii: Once you have a glass block over the Beacon, you don’t have to Shift+Click, just build as you normally do.]
Can you change Beacon color?
1 Answer. You can change beacon colors by placing a colored stained glass block above the beacon’s light. You can combine several different colors to make different colors to create different hues.
Do observers detect cauldrons?
The Observer detects an attempt to add water to a Cauldron from a Water Bucket, Water Bottle, Splash Water Bottle, or Lingering Water Bottle, even if the Cauldron is already full. It also detects removal of water by the same items, but only if the Cauldron isn’t empty.
Can observers detect Minecarts?
The observer block powers a comparator clock, which powers powered-rails below the minecart. You can use this reliably in a minecart system, as long as you have a minecart-destroying mechanism at the end of each stop (e.g. running the minecart into cactus).
Is there a way to change the color of a beacon?
You can change beacon colors by placing a colored stained glass block above the beacon’s light. You can combine several different colors to make different colors to create different hues. @Wouter You would need a piston system for that. – Kingsley Zhong Jul 10 ’17 at 16:35 This also works with panes. – Ben Jul 11 ’17 at 1:10
How can I detect the presence of an iBeacon?
Use region monitoring to detect the presence of an iBeacon. Use beacon ranging to determine the proximity to a detected iBeacon. Using a two-step process for detecting beacons significantly reduces power consumption.
How to check for beacons in an app?
In your app, you can look for related groups of beacons by specifying only a subset of values. Use region monitoring to alert your app when an iBeacon is nearby. To monitor for beacons, create a CLBeaconRegion object and register it with the startMonitoring (for:) method of your CLLocationManager object.
What are the values of the Beacon region?
The beacon region contains the proximity UUID, major value, and minor value of the beacons that you want to detect. Only beacons with matching values trigger a call to your delegate object. Listing 1 shows an example of how to set up region monitoring for a company’s beacons.
