you need:

1 Redstone lamp

1 Redstone block

1 daylight sensor

1 Sticky flask

3 Redstone

1 repeater

1 Redstone torch

1 glass block

1 block of your choice

Instructions:

first you make a 6 X 1 X 5 hole in the ground , after that you build up again on the ground except 2 , go to the corner where 1 block is down and look up there you put on the 3 height a sticky piston 1 release and then a redstone block , a daylight sensor is built on top of the bulb and a glass block on top of it (sets the daylight sensor to night) , now they build next to the Redstoneblock again a earth block , sorry the pictures are now a little darker I have not noticed that it was dark I hope it is not bad but it is better because then the redstoneblock is still down and you can build better, now comes there 1 times Redstone as in the picture , now you put a repeater next to the redstone , next to the repeater are now 3 earth blocks like in the picture , put on top of the wall again 2 earth blocks there , and on top of the wall another 1 block , now place Redstone on the 2 blocks (see picture) , put 1 redstone flare on top of the block (the redstone flare should be OFF now!!!) , When you're done, close the hole. , now put a block of your choice on it 3 examples (for modern houses) Quartz column: , (not exactly the best choice) cobblestone: , (for Middle Ages) Wood: , and you're done testing: , , Here are a few more tips: Tip 1: If you want you can take another block around the daylight sensor, for example, you have a stone away that you then does so: , Tip 2:you don't see any redstone! , I hope you enjoyed it. also look at my first idea because I put 2 sofa cushions on stairs (sofa) very cool idea.
