I'm curious what other people have been making with mesecons.

I tried making an elevator normal and one of those people use to load straw or hay into a barn. Neither worked though sadly.... My favorite thing I made was using command blocks to make a question maze, where you travel through answering questions from a choice of 3 buttons. But I have made a lot with Mesecon...

I love making mesecon mechanisms. If you want a system, just tell it to me and I will try to make it.

Do digilines and other mesecons/digilines-related mods count? I suppose the Luacontroller is from mesecons...

This nifty contraption is a 3-tier, dual sided, piston gate, that is powered by a single switch.
Image
here is a basic version of the mechanism:
Image
The idea is, the inner tier rails are powered first, and then through a delayer, the inner tier powers the middle tier, then, the same for the outer tier, and through another repeater, the outer tier, powers the middle tier when it retracts, that way, the inner tier is retracted to its open position.

figured id share this little tip someplace:
(note the button going into the side, and the switches that don't match the output lights)
Image
using the normal microcontroller, (not the luacontroller or fpga) and punching in this line of code:

Code: Select all

sbi(A,C);if(A)sbi(B,D);
creates a pule-updated memory cell component.

how it works:
A is the pulse-line input
C is the pulse-line output (for chaining them. i.e. registers)

B is the input. it is only read upon a mese signal on the pulse-line input (A in example code)
D is the output of the "memory cell" (microcontroller)

Another flip-flop

Here you have the front view:
Image

here you have the back view:
Image

This is the gated S-R latch. Two buttons S, R switch the light to yellow or red. This can be considered as system input. The state of the system on the input can be remembered at the time selected by the player and frozen for as long as the player wishes. The player does this with lever E. In a real system of this type, it is not the man who controls it, but the pulse of the clock. But this is a minetest. Alternatively, the system can be expanded and automated to select one of two possibilities at a certain time or event. For example, did someone else visit your base on the server when you were off-line. But it's easier to build something like that with a luacontroller, I guess. Here you can find a diagram and a table explaining how this S-R latch works in real.

2-state Lightstone Disco floor with custom pattern

How it works:
- a grid of straight insulated wires, with not gates strewn in where inversions in each row are needed.
- Blinky Power plant toggles the rows,
- mesecons torches convey the power state of the piece below them to the disco floor lightstone blocks.
- in this example, each odd row has an initial inversion.
- a not gate will match its above lightstone.
- a insulated wire will NOT match its above lightstone.

Figured id post this here as its simple enough to understand from the screenshot.

Since benrob0329 seems to like building elevators that don't use Luacontrollers, here's a 3-stop movestone elevator, with working doors, that doesn't use any Luacontrollers or even the logic gates: https://www.youtube.com/watch?v=FFMTDol5KvE - the video is a bit old and was taken before the actual building was built or the car buttons were put in. The picture below was taken later.

I managed to create a memory cell that uses only one FPGA gate.

Inputs/outputs:

Code: Select all

A: Input signal
B: Set state to input
C: State (output signal)
D: Set state to inverse of input
Notes:
If both B and D are on, it will set the state to the input signal (not the inverse, i.e. B overrides D)
If the input signal changes while B or D are on, the state will update accordingly

Gate configuration:

Code: Select all

A AND B -> 0
A OR B -> 1
NOT 1 -> 2
2 AND D -> 3
B OR D -> 4
NOT 4 -> 5
5 AND C -> 6
3 OR 6 -> 7
0 OR 7 -> C
Note that it relies on being able to read an write an output in each update which I'm not sure is "documented" behavior.

(To make this, I used a Karnaugh map with all the inputs and desired output and did simple boolean optimizations, such as De Morgan's law.)

I made a device that detects and saves the names of players who came within a 9 node distance of the player detector. It also saves the time in seconds that each player was in the area. The parts consist of a lua controller in the center, two buttons on two ports, one additional port having the digistuff player detector, and the other port having a scifi screen. The first number is the "page" number; one of the buttons increases an integer value, which is associated with a player. Each time a new player is found, the value is increased, so one of the buttons increases the value and the other button/ switch decreases the value.

I recently got a new computer, and I am looking forward to adding a video showing the function.

Here it is:

Hey cheapie,

how to program the touchscreen of your digistuff mod??

I really need it, so I hope you answer fast

Hi,
I have try to do the same like this

https://youtu.be/Qr4LoYF6W-M
but that can't work.
I don't undestand how is it working.
go a code like that

Code: Select all

 local var
if event.type == "digiline" and event.channel == "username" then
local var = event.msg
digiline_send("lcd", var)
end
but the username isn't read or saved ?
Can i have some help to undestand this ?

Hi, I save the name values inside a table. I can create a table using for j=1,100 do var[j]=0 end. Then every time a new player comes up I would do "username" which has the name of the person, and then do var[j]= "username". Then I would do j=j+1 when there is a new player. Does this help? Also, looking at your code, try event.msg[0] or event.msg[1]. Because I think this type of player detector as of the mod can detect multiple players at once, so it would make sense that itself/ the data is stored in a table.

I helped already by changing the code that it don't add the player into a table but that the detector sends the players, but I think yours will also work
