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!

 

This year, the JOTA-JOTI Service Circle is once again preparing several items to support the JOTA-JOTI 2025 theme: "Future Proof". First up is the name tag. This year's color is yellow and blue.

 

We also have a badge to support the theme. We're aiming for a slightly larger quantity in the shop this year, and we hope not to disappoint anyone. Please order in advance,of course. Also nice in Glow in the Dark

We also have a kit in development, and that kit will definitely be Future Proof. See below for a picture of the "SQUEEZER." This squeezes the last bit of power from an AA, AAA, or other battery. Alternative energy sources (supercapacitors or solar cells) can also be connected. The light can be switched on/off, or Morse code can be transmitted using the push button. The light color can be switched between white and red (ideal for night vision or stargazing).

The items can be ordered starting in August, and we'll let you know with a message on this website.

The non-profit website for scouts, radio amateurs and other creative people.
The ServiceKring JOTA-JOTI are scouts/radio amateurs who volunteer for everyone with an interest in technology.
So if you shop with us, you can order affordable kits, badges, flags and name tags because we run this shop in our spare time.
We do deliver, but not immediately when you place the order. If your order is urgent, please send us a separate message to info at Kitbuilding.org, then we can see if our logistics can process your order a little faster. Outside the peak weeks around the JOTA-JOTI we check the shop less frequently.
Thank you for your understanding, we certainly appreciate you shopping with us.

This website is now completely renewed. The old software environment was no longer suitable for running a secure website, which is why I created a new website with the latest version of the CMS and the latest version of the Webshop program. If you run into something that doesn't work properly, feel free to send me an email via our association email kitbuilding.org with 

The old accounts no longer work on this renewed website. You can no longer use the old website with the old accounts. You also do not have to create an account separately on the new website. When completing a new order, you can indicate at the end of the process whether you will complete the order without registering an account, or whether you want to record your details in a new account when completing the order. If you register then, you can check running orders and older orders
