Some guy managed to make one...

That link was featured on Hackaday!

Sounds interesting... I'll add it.

I think it's a good idea, shouldn't be very hard to do either only problem is that who will do it? I have to take a look at the code of pipeworks and digilines. I do not know if i am able to do it. I'll try to make it, but I have to find out how to use the pipeworks API. I'll surely make the detect...

There was also a bug in the cardboard computer mod, and there's a bug in the circuit diagram in this topic. Everything is buggy...

Too sketchy sketch... Apart from the protection diode for the solenoid, I have to add a 3.3V regulator after the two diodes and feed it with at least 6V (maybe 5V from USB ports depending on the regulator's drop). I plan to use a switching regulator as linear ones like the 1117 are inefficient (~ 3...

I got very shocked when I saw this on github. It's a smartwatch designed by Jeija!!! It has also minetest controller mode :D. It has that ESP8266 Wi-Fi chip at the core. It's a cheap and powerful chip for Wi-Fi... The ESP8266 is actually much more powerful. It can render dynamic 3D meshes and decode...

I made a tutorial using your mod: https://www.youtube.com/watch?v=_s9CVFaw1eI

Wow, my work is on YT!!!

Software update to my cardboard-PC and a new mod for Minetest: a fork of the computer mod that adds handheld games and cardboard computers. Releasing it today.

Here's what I got after drawing some devices in Fritzing:


The digiline flash memory is there just for fun. It's just a 24LCxx I2C flash chip (xx is the memory size).

I'm still alive, but pretty far from Minetest. Moved to 8-bit chips (= Arduino) and some small mods for Minetest (= elytra mod without 3D models).

Most important thing in development:

(Yes, it's a bit off topic...)

Back after a very long while... My laptop's keyboard broke and now I have an uncovered computer. And I'm using a mini wireless keyboard which is usable just for quick coding and web searching, and not intended for playing MT. So I can't debug my mods and make complex stuff. But I got an idea for gho...

That's impossible. Minetest has no support for custom cameras and recording videos. And it's not possible to stream videos on a texture, so the TV would be also impossible. (Impossible until you patch MT and make a pull request, but that's not easy!) The PC, however, is possible. It could be a (sand...

Here's a quick Fritzing drawing about a luacontroller project:

I will make the circuit board design in KiCad soon.

If you want to learn hardware, I suggest you to start with Arduino , which is an 8-bit microcontroller packaged in a fancy circuit board, with one of these dongles built in. There are many tutorials and examples on the web about Arduino . Just search for them :) If you know a bit of Javascript or Lu...

While making a project of the programming interface for the luacontrollers, I saw an USB-to-serial dongle on my desk. And I thought it could be used. And it can be used to program the luacontroller . Here's one of those magic dongles: https://forum.minetest.net/download/file.php?mode=view&id=460...

I found an issue with character LCDs: older LCDs need 5V to operate (newer work with 3.3v), and the mesecon circuits are 3.3v. Then we have to find a display that works with just 3v (the i2c adapter works both at 5 and 3 volts) or make some type of boost converter . And boost converters are not DIY...

About the screen + keyboard set, there is a mod that has one, but I can add it anyway.
However I'm busy these days in building a javascript computer and other things with chips, including luacontrollers in real life.
I will add it when I can.

I got some ATtiny's and I'm doing some testing. Just 8K of flash memory, but that's enough (lua scripts are compiled with some custom thing to C and then assembly language with gcc-avr). Tiny25/45 could also be used (they are identical except for the amount of flash memory, and they cost less). I wi...

I'm not sure about digiline command blocks. They are easy to make, but there are security issues: Minetest allows executing commands only by players unlike Minecraft that has a special safe "bot" used by command blocks Mesecon command blocks are locked and only the owner can change command...

That LED driver would be simply a resistor + transistor which is only 2mm long... you can place it behind the LED, and you need just one for all LEDs. You even don't need a transistor if you want to control a single LED which isn't very bright. For noteblocks, we could add the same capacitive sensor...

I'm working on real life mesecons and digilines too! Here's the topic about that. I need to chose a chip to use for the luacontroller... The code for the luacontroller could be compiled into C then machine code (with gcc?) and sent to the controller with some programmer block or something you place ...

I have some microcontrollers around and I like programming MT's virtual luacontrollers, so I decided to port these luacontrollers to real life. Maybe with pistons, LCDs, and meselamps, along to all other mesecons devices. I decided to use a STM32F103C8T6 , which is a tiny 32-bit microcontroller avai...

The same for my JTAG and the clock factory. It consists of four parts: the stocking unit, with chests for luacontrollersand materials, the programming factory that programs several luacontrollers with the display drivers and the timekeeping program, the factory assembling the clock and the remote te...

I'm working on something more interesting: a fully automated digital clock factory! It takes your orders via digiline and make a clock as you want (you can customize light colors and the base material, and even add a custom alarm!) It programs the luacontrollers with my JTAG programmer mod (still in...

Did you used a delayer-based timer in the first version? It's not reliable... it stops after a game restart... Why did you don't use red plants, they generate an interrupt every 3 seconds! And why do you need a hardware timer? Here's my improved code, it does not need any hardware timer. Port D is u...

And another good source for free music Newgrounds.com, I got some music from there and the artists only require you to link back to them when you use their stuff. Say that to me, I have 50 newgrounds songs on my pc... And I injected one in the main menu. That's simple: Go in your minetest directory...
