Minecraft Piston Lighthouse

Saturday 23 Jul 2011 10:33

The Minecraft piston powered lighthouse uses sticky pistons to reveal and hide a netherrack bulb in sequence, giving the illusion that the light is circling round like a true lighthouse. It was developed by myself (Kevblog) and Bl0ke. We used Plotz online Minecraft modeller for the basic lighthouse model and then adapted that with the piston system. To look 'correct', all the redstone wiring had to go on the inside of the bulb meaning the circuit had to be very tight. See the lighthouse in action below:

How the piston lighthouse works

At the base of the lighthouse bulb, a row of 3 sticky pistons go up. From the roof, 3 pistons come down at the same time. This hides the bulb at one of the 4 sides. When the pistons lose power, the bulb is revealed again. The redstone power loops in a circle using delayed repeaters, and each side follows the other in turn. The base and roof circuits are the same and are initially powered at exacly the same time to run together.

The circuitry

See the screen shot below. The power initially comes in at the bottom left. A repeater directs it to the left hand (9 o'clock) set of 3 pistons. The power comes out into a repeater with the highest delay and then powers the top (12 o'clock) set of pistons. This process repeats around the the right hand and then bottom set of pistons then continues in and endless loop. The intial power comes from a switch and so has died out (a constant power source would have left all the pistons on all the time).

The lighthouse 'roof' circuit. The base is the same.

Update: I've added the circuit video below:

Not quite perfect

The tight circuity means there isn't enough room to keep the wiring which powers the roof circuit on the inside. It juts out slightly, so we've placed this on the least likely to be seen side of the lighthouse. This 2x2 spiral of blocks takes the power from the bottom to the top. I know 1x1 vertical power can be acheived, but it also had a delay. In this case the top and bottom circuits must be powered at the same time. A lot of people are requesting vertical redstone wiring. If Notch were to implement this, such problems would be solved.

How about adding a solar detector so that it turns off during the day and on at night?

Attempting to do this, can someone link me to screen shots of their light house / and or top and bottom circuitry.

You will be able to "perfect" this design by using the upcoming redstone block and some sticky pistons. Remove the 4 inner repeaters and redstone wires. Push a redstone block up where the removed wire is, control the pistons from below (or above) in the same circular fashion using repeaters.

cool looks awsome

Now that Redstone Lamps have been released, I found that replacing the sticky pistons and the blocks they move with the lamp blocks works better for me than the piston design. It requires fewer overall blocks and is easier to build if you have access to the Nether (that or I just can't find slimes to save my life). The main difference is that it only lights one side at a time instead of only dimming one side at a time.

hey, just a quick thing, using redstone torches from the botton to top layers the circuit can fit inside the circle. all that needs to be done is adding repeters to and from the torches and put them on full delay then put the top layer on full delay. good design tho :)

Just stick a button on the circuit somewhere, the single pulse given will start off the circuit and keep it going continuously

How do you power this thing? Surely to get the on off effect you'd need a separate piston somewhere controlling current flow or something? Please tell me how to activate this thing. I've spent ages building it now it's just sitting there uselessly.

Hello!
I'm trying to build your lighthouse but I cant decide one problem: when I power this circuit it doesnt repeat, pistons make only one turn. how to resolve it>?

i made one where the wiring is inside, used your generator for the tower itself. if u want, stoot me an email and we'll compare notes.

Well macaadmia nuts, how about that.

just as a comment to those who are building this, in that photo the repeaters on the pistons should be in a series of 2, 3, then 4 clicks to give the rotating appearance. If you build straight from picture they will just compress together at same time. Just wanted others to not run into my problem :D

Is their any way you could do a video or full explanation about how to power both floors of pistons at exactly the same time? I can get them to work but not at the same time

How do u turn it on? I've tried most things but they don't work. Plz tell me how to activate it.

@Kayli, I used: diameter 9, floors 2 and step every 2
23 Aug 2011 11:17 by Kayli
Wow!! This is amazing! Can I ask what diameter you used as I'd love trying to recreate this :) Thanks! Keep up the amazing work!

Hi there! I'm new to Plots but already adore it! Thank you for what you do!
I think i have found an easy and hidden way to connect the upper and lower levels together. If you are interested, drop me an email at: MyNick@MyWebsite.co.uk, where the My variables are from this comment :D

MCedit schematic would be great :D
