Meter v2.002.000 is Availible!.
03/31/2026.
Meter v2 is finaly out now. This circuit can scan real-line objects and then read its colours, using a colour detector by hit the NO pusbutton and then release this button. After scan the real-life object, the from the colour detector readed colours are printed on a liquid crystal I2C LCD display as RGB colour values. You can download this project from the 'JCadsand Learn' page as breadboard project to build it.

The Hunt to the Core behind Menarlination!.
03/22/2026.
Things are getting a bit more exciting. Menar v1 / Pre-progress Fool Proof 1A is launching. The question is as follows: could technology soon completely regulate our dreams? Jamie van Cadsand (that’s me) is starting the first real pre-progress experimental fool-proof tests with it.
DISCLAIMER: Jamie van Cadsand is testing it on himself first. And therefore wants to know for sure if it works.

Menar Technological Experiments 1 / 1 has been started!.
03/14/2026.
It has taken longer than expected, but my first pre-progress experiments at the Menar Technological wiring level have started. It remains to be seen what the results will be, but at this moment (as mentioned earlier), the experiments are only at the electronic wiring level. The virtual gadget will not be available for the time being. I also have not yet scheduled a release date for this complete do-it-yourself project regarding both hardware and software. And for the time being, I do not want to say much about the technical details regarding Menar Technological.

Menar v1. I am Ready for my First Experiments.
01/30/2026.
Finally. My pre-progress experiments on Menar technology are about to begin. But not yet with my virtual gadget. No, first there will be experiments at the electrical wiring level only. The complete design isn't there yet and won't be for a while. So, for now, my first Menar Technological experiments will, as mentioned, only be performed at the circuit level. And only later at the virtual gadget level. It will still take some time before the entire Menar Technology is released to the world as a virtual gadget and can be downloaded as a project from the download page within Menar. But this will hopefully be THE BEGINNING of this enormous innovation. I expect that, if all goes well, my Menar virtual gadget will appear on this website in the summer of 2028. But I can't promise anything yet. There is a lot of misery in this world, and I don't know how things will turn out.

Meter v1.002.000 is Availible!.
01/17/2026.
Meter v1 is finaly out now. A completely new project i was working on. This project use a DHT11, a LDR, a Liquid Crystal Display to print the temperature, humidity and licht on the screen. And even a NO Pushbutton with a 100nF Capacitor to read the next sensor pin. Now you can download this project from the download page outside Menar.

Meter v1. A New Project is in Progress.
01/11/2026.
Before i start experiments on Menar Technology. First i work on an completely new breadboard project. Called Meter v1. A Simple Meter wich can display the environment temperature, humidity and even light range in values on an LCD Display I2C. Working with an Arduino Uno R3, a DHT11 Sensor and a LDR. Now i am working on it to do the last things, before release it to the download page outside Menar Technology. I Hope to release this project soon.

JCadsand 2026 Starts Now!.
01/02/2026.
Now, a new big project will be started this year. Called Project Menar. This will be my first real technology I've been working on the next years. Its still under construction and it can take a lot of time. But i hope to make it true tomorow. A new page is added to this website, called 'Downloads / Menar' to follow it. First, i will start experiments on breadboard level soon. And if it will works, i plan to create a file-based PCB of it and create a plan to invent this as a completely real working DIY-project to bring it out under the GNU General Public License on this download page in the near future.
This can take a lot of time. But i hope this will be succeed!.

Menar Technological Experiments at Breadboard Level.
12/20/2025.
It will probably take a few more weeks. But the initial preparations for the Menar Experimental area are already well underway. I already have a power station in my room, just in case of a power outage. A 9V battery charger with the correct batteries. Later, I also want to add a Li-Po battery charger with Li-Po batteries. Besides printing out a lot of electronics information for building and programming my Menar Machine, I also have a lot of purchases to do. At least, if all goes well. And then I want to start working out my first breadboard-level experiments on paper. And actually put them into practice.

Will Menar Technology becomes Reality !?.
12/11/2025.
Menar Technology. Will it become reality?,
I (Jamie van Cadsand), the future pioneer of the next virtual gadgets, am working hard to make these drastically changing simulations a reality. I'm putting everything down on paper so I can soon conduct some experiments with it on various breadboards and preliminary, working prototypes. I don't want to say yet how this technology will take shape. But if it ever does, it would also be free and open source for DIYers. So people can build it themselves from the future manual at home. But it will still take some time before it's online. So, of course, don't expect it to be possible anytime soon. This is just the beginning of the enormous innovation. But you never know.

Light v3.001.000 is Availible!.
11/22/2025.
Finally. My last Light Series is here, for now. Light v3. This is a lamp with sixteen white LEDs controlled by two 8-bit logic shift registers, a 10kR trim potentiometer, and an Arduino Uno R3 board. You can, of course, also download it from my download page.

The last Light Serie is in Progress!.
11/07/2025.
To wrap it up. I'm currently working on the final Light Series, Version 3. This will be a lamp with not just one, but sixteen white LEDs. Although I don't want to say much about it yet. I also don't want to reveal how I plan to control these sixteen LEDs and what this lamp should be capable of. It's just a few things. I can't work on it yet due to a component shortage. But I do have some theoretical ideas.

Will Menar Technology Be the Next Project?
11/06/2025.
Right now, I'm occasionally working hard on my latest LED circuit, Light v3. A lamp with sixteen white LEDs. But what will my next project be?!
I already announced it last month. If it were up to me, there would be a huge surge in innovation. And yes, anyone with a good memory will probably remember: dreams will become the virtual gadgets of the future. The era of the so-called Menar Machines is coming. At least, by 2026, I want to describe a comprehensive theory for it. Although I don't want to reveal yet how this technology will take shape. I hope to have my first Menar Machine online as soon as possible. Who knows, maybe within four years. But of course, you never know how things will turn out. Because there's a lot of misery in the world.

Light v2.004.000 is Availible!.
10/31/2025.
Finally. My brand new lamp project is now out. Light v2.004.000. This is a completely new variant of my Light X Series. This lamp is normally on. But it turns off as soon as you press and hold all three breadboard-mounted pushbuttons. These then control the two 2-Input Logic Gate ICs, including the potentiometer and subsequently the LED. On to the next project.

An new Light Serie is in Progress!.
10/26/2025.
Now that I've most likely released the last Light v1 series, I'm already working on a completely new series, the Light v2. This will be a logical lamp that should only be able to be switched on in two or three ways. But I don't want to say too much about the technical details yet. It will be a completely new series.

Light v1.007.000 is Availible!
10/24/2025.
It's been a while since I released an update to my Light v1 series. But here it is. Light v1.007.000. An update to v1.006.004. This one has simplified instructions and works with an Arduino Uno R3 instead of a Nano. It's also built on a cardboard base, which makes it easier to grip. This update now is downloadible from my download page.

10/22/2025.
A new update to my Light v1 series is coming. This time, it features an Arduino Uno R3 on a board with a small breadboard, making it easier to grip. I hope to release this soon, before I start working on a new Light series.

Will dreams become the next virtual gadgets?
10/12/2025.
I was already talking about it in 2014. The era of the Menar Machines. Virtual Worlds in which people would have to immerse themselves. Starting next year, I plan to investigate how this enormous technology should become a reality. At least, if it were up to me. I certainly don’t want to say anything about it technically yet. But this technology should change your life drastically. Forever.
