During the JOTA-JOTI 2018 the JOTA-JOTI Funcube Challenge played for a small audience.AmsatUK

During the JOTA-JOTI, the space cube sent a coded message and the first challenge was to receive the signal during a passage so that it could be decoded.With receiving equipment, antenna and an SDR dongle, the message could be converted into letters that resulted in a text message in code. See the 2nd challenge here.

Then an enigma was needed to decode the text into a correct text.And setting up the Enigma required the answers of 10 questions that had to be looked up on the internet. Then finally there was the solution.

De uitkomst was dan ook:


 And during the weekend the first entries came in already.

There was an entry from Scout: Roel Botter, age 26, Scout / Ham operator: Martin Cohn, PE2MGA, age 41, and Scout: Roel Botter, age 26, Ham operator / human rotor: Arjan Doek, PA5AD, age 48

Equipment used: 10 element 2 meter beam, SSB 2m head pre amp, 6 element 2 meter beam, Kenwood TS-790, Heavens-Above android app for satellite tracking, laptop with FUNcube-1 dashboard



After a few attempts, the message was received and not with an automatic antenna rotor, but by Scout Arjen.

James from the Sixth Staines Scouts from the UK sent us a link from a movie about their Engima action. https://www.youtube.com/watch?v=4LW-GEFfzyk

REBEKA from the 15 RR VALENTES DE DAVI group from Bazilie, age 15, also sent us a photo of their Fun cube challenge team.

 En Roland van HAM radio: PY4ZBZ en de scouting groep Grupo Escoteiro 86° Mafeking MG photo 2018 10 21 16 30 33stuurde een weblink van hun bevindingen: https://www.qsl.net/py4zbz/fc1.htm

And Roland from HAM radio: PY4ZBZ and the scouting group Grupo Escoteiro 86 ° Mafeking MG sent a web link of their findings:

There were also less complete solutions that showed that the part with the enigma was well done.

After the JOTA-JOTI weekend, several good entries arrived. With the wish to definitely be able to take part in such a challenge again next year

The winner of the FunCube Challenge: Paulo PV8DX from Sao Vicente Boa Vista-RR Brazil was given a battery tester, a morse phone, a signal finder and a lantern next to the name bands.

100 name bands are divided among the 8 groups that have submitted an entry.

The Service Kring JOTA-JOTA supports the national organisation JOTA-JOTI of Scouting Netherlands with a warehouse module with articels like:

  1. Kitbuilding
  2. Name tapes
  3. DVD/CD
  4. Badges
  5. Individual parts

The Service Kring JOTA-JOTI tasks are carried out entirely by volunteers. It may happen that in periods of vacation and camp-periods some delays in shipments occur. We hope for your understanding in this matter.


The Service Kring JOTA-JOTI has prepared a number of articles for  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 2018 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.

The Badge is sold out






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. 


A second kit called  in the year theme is the Space Cruiser.


The kit is sold outSpace 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?
