Hey, did you spot me yet?
Then you're a real scout 😉
Because since August 14, 2026, I am also physically available in the Servicekring JOTA-JOTI webshop.

.

Who am I? I am the Chameleon, a small soldering kit that can change color and loves to get moving along with you.

A somewhat handy scout can build the circuit board so that it can also be safely worn on clothing or attached to your bag, without the risk of damaging your clothes.

If you prefer to solder the kit the traditional way, that is of course perfectly fine too 😀

You can also play all kinds of games with the Chameleon; need inspiration? Then keep an eye on our website for game ideas.

That way, you get double the fun from your Chameleon: a fun soldering activity followed by playing a nice game together.

Nature lovers among our scouts, as well as budding Freek Vonks, can also indulge themselves with this electronic Kamili 😉

Additionally, you can find the JOTA-JOTI annual badge and the name tag for 2026 in our shop. Don't wait too long, because once they're gone, they're gone!

   

Chameleon

Spring is already emphatically present and the summer holidays are not that far away. It is therefore high time to update our JOTA-JOTI-minded audience about the state of affairs regarding the articles that we as Service Kring JOTA-JOTI prepare annually to provide technical support for the JOTA-JOTI and that can introduce the youth to the technology.

We are releasing a name band for our uniforms again.This year's name band has a green background color with gray letters. and it features the theme of this year's JOTA-joti: DIGITAL PHYSICAL.

 

Then we also have a badge with the same theme on it. On the website of Scouting Netherlands  you will find everything about the theme

If you light up the badge and then view the badge in the dark, you will see another Glow in ther Dark effect

 

We now have the name tags and badges in stock and sales have started. The soldering project will also go on sale soon.

 

The soldering project for this year is not quite finished yet, but I can already reveal a tip of the veil.

The soldering project kit is called the Chameleon, or Chameleon  in pas. dat English

The soldering project kit is called the Chameleon, in English. Naturally, colors are involved, which explains the name.

The Chameleon is interactive again: You can vary the colors of the Chameleon's LED by pressing a button. Additionally, it is possible to activate a motion sensor, causing the Chameleon's color to change in response to movement. The PCB can be worn on clothing, so the components can be mounted using semi-surface mounting, but it is also possible to build the PCB using traditional methods. Furthermore, the Chameleon has a few contact points for connecting external switches for color change. These points, as well as the motion sensor, offer possibilities for games.

SALES STARTED TODAY.

 

The Service Kring JOTA-JOTI will also have a booth at Amateur Radio Day. We'll be sharing a booth with the National JOTA-JOTI organization near the stairs on the first floor. Booths 2600 and 2612. You can pick up your order at our booth if you placed your order and paid before November 10th. Select "PICK UP YOURSELF" as the shipping method and indicate in the comments box that you'd like to pick up your order on Amateur Radio Day. Will you be visiting us?

We use a lot of electronic devices that use batteries. Sometimes the batteries can be recharged, but often not.

Of course, we return the non-rechargeable batteries neatly to a collection point, but...... they are often not completely empty yet! They may contain too little energy for the device they come from, but the energy has not yet run out. With the "Squeezer" you can get the last bit of energy out of the battery (squeeze!) before the battery disappears into the recycling bin.

So what does the "Squeezer" do with this last bit of energy? The "Squeezer" uses the energy to light up a bright LED, so it's a flashlight!

You can choose between white light or red light. This can be useful as a marking in the dark, for example when you walk along a dark road. White light on the front, red light on the back.

But the red light is also useful when you go stargazing, for example. Astronomers like to use red light when they are working outside. In the dark your eyes are used to low light, when you turn on a white flashlight, your eyes have to get used to bright light again, after this it takes a long time for your eyes to get used to the dark. With red light, this is much easier!

The "Squeezer" also has a push button with which you can use it to give light signals. This way you can communicate with light-Morse signals!

AA and AAA batteries fit in the "Squeezer", these are the most commonly used batteries nowadays. For Scouts who want to experiment, the "Squeezer" also has two special connectors. Other energy sources can be connected to this. Think, for example, of a 4.5 Volt battery or a 9 Volt battery, or use solar cells and supercapacitors. You will have to tinker with some wires.

If you are a real researcher, you can also use these connections to connect your homemade battery. You can make your own battery with, for example, a lemon or a glass of cola and a galvanized nail and a piece of copper wire. Will you be able to generate enough energy for the "Squeezer"?

Finally, two important instructions for use:

1. Do not use rechargeable batteries in the "Squeezer"! Rechargeable batteries cannot withstand it when they are completely discharged (all energy out). This will break down the batteries and prevent them from being charged (properly). So only use the "Squeezer" with alkaline (disposable) batteries.

2. If you don't have an "empty" battery, you can of course also use a new battery. Then you can enjoy your "Squeezer" even longer!

With the "Squeezer" you are energy-efficient, green and Future-proof as a Scout!
