So, I have this:

Redstone Line

Now, what I want is a repeater that would work while keeping the unlit lamp on.

Yeah, that one right there:

This one!

I have this already:

My version

...but the piston turns on and off repeatedly until the input is off.


It looks like you're running the power along a row of raised blocks behind the lamps. This normally works because redstone on top of a block will power the block below it, and that block will power blocks adjacent to it. This is why the repeater is causing a "dead" spot: the repeater isn't powering the block below it, so nothing is powering that one lamp.

Instead of powering a row of blocks beside the lamps, power every second lamp directly. Directly powering a lamp will light both the directly-powered lamp and the two beside it, as the middle lamp powers its neighbours:

A single redstone input powering three adjacent redstone lamps

Because redstone in a line won't directly power an adjacent block, to do this in a line you have to have the redstone "bus" one block distant, with singleton lines going into every second block. This conveniently gives you a place to put your repeaters:

Redstone lamps powered by a nearby redstone bus incorporating repeaters

Of course you can also power every third block instead of every second and it will work the same. If redstone is no object I prefer the redundancy and simplicity of two-block spacing, but three-block spacing works better when redstone dust is a scarce commodity.

  • @PieCrust Bah, you're right. My redstoning is rusty. Mar 15 '15 at 2:42
  • @PieCrust Got a fix for you! Incoming... Mar 15 '15 at 2:45
  • Right, so this is clever. However, there are two issues: One, I'm trying to keep the design as compact as it is now. Two, I was only using the lamps for placeholders, in reality it's pistons facing away from the redstone.

  • I can send world file if you want so you can see what it really is.

  • @PieCrust Ah, yes, pistons are a non-opaque block and power differently. Possible to do, but unfortunately not as compact as you want and IIRC uses lots of repeaters. Mar 16 '15 at 15:09
