Good luck! The FUNcube satellite challenge team

AAmsatUKIn space, satellites can be found. A recent development in this area are the “CubeSat” satellites. Normal satellites typically have a size ranging from that of a washing machine to a small truck.
CubeSats have the size of a milk-carton! This challenge focuses on the FUNcube-1 (AO-73) Cubesat sattelite. During the JOTA-JOTI a special, coded, message will be transmitted. This message can be received with a simple 2m handheld antenna, e.g. HB9CV, a small yagi or even a vertical, and a SDR-dongle or any SSB radio for 2m. The data is sent by the satellite on its telemetry channel of 145.935 MHz (1200bd BPSK modulated). You will need to set your receiver to Upper Side Band (USB). If you use a FUNcube dongle, you can directly receive the satellite. The message is coded using the Enigma cipher machine. The deciphering key and Enigma correct settings can be obtained by answering the questions below. The message sent by the satellite follows the following format: JOTA JOTI START coded message
STOP Your deciphered message can be mailed to: JJ.Satellite.Challenge (at) kitbuilding.org ( (at)=@)  The mail should contain your name, age, country and Scout group name and the correct answer!
If you have any pictures of the reception of the satellite with your group, this would also be highly appreciated, we would love to see how you did it!  If your answer is right and mailed before the 1st of November 2018, you will participate in a raffle. The winner will get some products from www.kitbuilding.org
Have a lot of fun and good luck! Best 73s, Wouter PA3WEG and Jeroen PE1RGE





1 of our creative staff Charissa from the Service Circle JOTA-JOTI designed a 3D scarf ring and made the design available on thinkercard.

Charissa also designed the badge this year with theme Expedition Cosmos

Now the JOTA-JOTI is coming up soon, we want to give you a status of the products sales of this moment.

The orders come in daily with big quantity’s, and the last moment to order where you may count on receiving your products before the JOTA-JOTI is also approaching.

The last day to order and pay your requested products is October 13. Later orders will be handles after JOTA-JOTI because our team is then also busy packing there goods to prepare for their own JOTA-JOTI2018.

At the moment already one product is completely sold out and that is the SPACE CRUISER.

The Badge is now also sold out. Nametapes and the main kit fir this year being the Claplight are available in large enough quantity’s so there will surely material enough to expand your JOTA-JOTI with these nice goods. So order NOW please, and process payment before October 13.

Then we want to remind you all that many solder kits are available throughout the whole year so any day could be a nice day to have a technology program with your scouts of all adges.

Al remark and ideas are always welcome on This email address is being protected from spambots. You need JavaScript enabled to view it.

Do have a nice JOTA-JOTI

The Service Kring JOTA-JOTI has prepared a number of articles for the next JOTA-JOTI2018. With this you can prepare a piece of technology for your members in your program with your scouting group.

ClaplightMKIIklTHE building package for this year is the CLAPLIGHT MKII. You may have seen this kit come along in 2017. We then prepared a small run for the MOOT2017 in Iceland and a small remainder was also offered on the website. This year we have enough in sales.The Claplight MKII can be switched on by e.g.by clapping in the hands, ore when being put into a jar, by tapping against the jar. The Claplight MKII can be switched off with any infrared remote control. Aim it at the print and press a button, the Claplight MKII will now go out. An old remote control, if you do not have one yourself, can often be found at a thrift store.With the switch you can choose on the print whether the Claplight MKII is also switched off automatically. When the switch is in the ON position, the CLaplight MKII is automatically switched off after approximately 45 to 50 seconds.You want to have this kit in your tent because the High Power LEDS give you a lot of light when you go into the tent in the dark..

 Badge 2018 Expedition Cosmos

In addition to the construction package, we also have a themed badge around the theme EXPEDITION COSMOS. (Thank you Charissa)This badge will also stand out in the dark because the stars en theme text will also be visible in the dark.






Then we also made a name tape, With this you can decorate your uniform and show that you participated in the JOTA-JOTI2018 again





Then we have taken a new direction with the supply of building kits.The kits of the last years became more fun, and could do more and more, but the construction time also became longer and sometimes a bit more difficult. We start this year with a series with smaller kits that contain fewer parts, and can be built by younger scouts (with sufficient guidance of course). We called them as "Cubscout kits" as a work name. The cost price of the kits will also be a bit lower.


First comes the lantern: the Latern2018

This building package contains only 10 parts and the PCB. The LED light will come on when you touch the large contact surfaces at the bottom and immediately off when you release. If you press the push button, the LED light will go on at full strength and very slowly. 


Our designer Jeroen is working on a second kit called the Space Cruiser.


Now it's doneSpace CruiserKL

Then there is a new choice in the main menu.Technical Games. A creative addition to our team in the person of Jeroen van Kuijk is concerned with coming up with games with all the beauty that we always offer on our webshop. The first 3 games can be found there




During the DvdRA, we received from Hans Boonstra, a satisfied customer, the schedule of an auto power on / off circuit for the bat detector. If you add this, the bat detector automatically switches when you connect a headset.

The days to the JOTA-JOTI 2017 are counted.

But even now I would like to show you some interesting new items.

1   De RF-INTERFACE as a kit ca now be ordered and the usermanual is toegevoegd

2 De Morse Phone user manual is written in the Norwegian Language by Peter Ebsworth uit Forland, Sotra, West Norway.

We were equally excited about how the extension of the Morse Phone would be, but here it is.

It eventually became a circuit board mounted underneath the Morse Phone.You will have a full mobile signal device


Addendum The Morse Phone

Now that a large number of Morse Phones have been sent, we have also received some feedback from our customers and we would like to share them with you

It concerns: thePiezo speakertje,Coil,Tip for construction

The JOTA-JOTI Service Service is now busy with the shipments of the new products for a month. Even in the Netherlands, many orders have already been sent to Europe, and also outside Europe, the world. See the maps below.



This summer was the 15th World Scout Moot held in Iceland from July 25 to August 2, 2017. At this camp Remko Welling along with the Service Kring JOTA-JOTI developed a kit to the MOOT2017 soldering with the participants in the section Radio Scouting and Electronics activity. The kit for this purpose was the Claplight 2017 MKII

Every year, the Service Kring JOTA-JOTI developed a building kit for the scouts to solder themselves and then enjoy themselves with the result.

Morse Phone2017 1

For this year, "The Morse Phone" has been developed, as the name suggests, you can start with this kit with Morse code. The Morse Phone is a Morse-buzzer that can be used independently, but can also be linked with other Morse Phones, communicating, after all, is done in pairs! The Morse Phone is inspired by the Fuller phone. For the technicians, an article on this subject can be found elsewhere on this website. Google also gives a nice explanation of the origin and use of the Fuller phone.

The kit comes with all the components except the 9Volt battery.

GD5 0198 3Our secretary was recently surprised by the VERON with the issuing of a gold pin for his commitment to VERON, and SCOUTING. The VERON magazine published the following article:







Here you can see who are behind the JOTA-JOTI Service Circuit.

The photo shows all members by name. Then I would like to mention which posts belong to the members:



In all these experiments make use of the contacts between the blades of the Light Mill. It's easy when you attach a piece of flexible electrical wire here. Stick a piece of tape over the light sensor.



Color  the patches starts and  finish with a soft black pencil (preferably 6B). Slide the metal surfaces
paperclip on the  surfaces, connect the wires to the paper clips. Draw a path through the islands and bridges. If the path is well marked, without interruptions, the mill will run faster.





LM7Lost your wire???
In a pile of wire ends it is sometimes difficult to find the acompanied ends. Try it with the LightMill!





Pak both the end of a wire of the Light Mill bite. Join hands, watching a good look at what happened!



Which materials conduct electricity? Try it with the Light Mill!


Connect different resistances between the wires. What can you say about the speed of the mill and the value of the resistor?
