UPDATE: (8-10-2021 Badges are sold out now)

The JOTA-JOTI is approaching, so I would like to provide an update on the status of items and shipments.
We are now working with the utmost urgency to get rid of all the packages. As we promised, we will ship the orders ordered and paid until October 9th in time for the JOTA-JOTI

What is ordered after October 9th will be shipped after the JOTA-JOTI and you will not receive it with jOTA-JOTI.

Building kits:

With regard to the Lasergame MKIII the following: The PCBs have not yet arrived 😕 Certain components are also/remain problematic. It will eventually work, but for the JOTA is now (unfortunately) no longer realistic. This means that the Lasergame MKIII will not be available with JOTA-JOTI. We previously reported that the small kit (Orgel) will not be finished in time either. Hellas has given us more time, but has also created many more obstacles. Such as less available time with our volunteers, and parts that are difficult to obtain.

We will continue to prepare for both kits, and as soon as they are available we will publish it on this website



What is social safety?

Social security within our group means that members feel and feel protected against cross-border behavior in the association. Cross-border behavior is understood to mean exceeding standards (code of conduct) and the law. Such as: morals, embezzlement, bullying, peer pressure, violence etc.
Together with Scouting Nederland, we actively participate in the protection of all members at local, regional and national level. Awareness and prevention are important ingredients that contribute to a socially safe environment.



Code of Conduct

The code of conduct sets limits in contact with minors. This code should be endorsed by anyone who fulfills a position within our Scouting group. We use the Scouting Nederland code of conduct, which you can download here. All volunteers are made aware of this code of conduct at the start of their voluntary work.

Certificate of good conduct

When you think of children, young people and Scouting, you immediately think of play, fun and a challenging life. No one associates these words with transgressive behavior. A mandatory Certificate of Good Behavior (VOG) is one of the measures that the Service Kring JOTA-JOTI  has taken to provide a safe environment within our organization. The Scouting Netherlands Household Regulations offer sufficient possibilities to exclude and / or unsubscribe members in the event of cross-border behavior and  or failure to submit a VOG.

Appointment Policy

The Service Kring JOTA-JOTI has a volunteer who coaches and guides our team members. To ensure that the wishes and expectations of (new) volunteer (s) match with the wishes of our organization, we not only conduct introductory meetings / intake interviews, but we have also agreed in accordance with the Scouting Netherlands Internal Regulations that the first 3 months will be a kind of trial period. to be. We also request a VOG for every volunteer. In the trial period we zoom in further on the substantive function within the team and inform our (new) volunteer about all kinds of training courses that he / she can follow to feel as part of our organization as quickly as possible. As a board, we use various methods developed by Scouting Nederland.

Confidential advisor

Our board members will be happy to assist you in the event of a calamity situation, such as transgressive behavior, an accident or a death. Send an email to our confidential advisor via email address: This email address is being protected from spambots. You need JavaScript enabled to view it.
You can also always contact the national reception team. This team consists of national volunteers who advise group boards on how to deal with this. These volunteers are experienced in assistance and have a lot of experience with these kinds of situations. They refer Scouting groups to the appropriate authorities if necessary.

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.

IMG 3558 resize

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.

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

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.

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?

Digi-Dice 2014

This year, the Service Kring JOTA-JOTI again managed to establish a fun and educational construction project what we called Digi-Dice. As in previous years, this kit is intended for use by children soldered together (under supervision) and to become familiar with electronics. Besides this is a nice kit it is also useful because it can be used in Scouting games on various ways

Digidice2014 Kl1


Usage and options:


Once the batteries are installed, the Dig-Dice and performs a self-test.

All segments go on one by one and then burn all segments simultaneously. The Digi-Dice is now ready for use as dice. Press the button to start the dice, a running light appears and a number is displayed. Press the button to throw again.

However, the Digi-Dice has even more possibilities. By holding the button down longer, you can switch to another mode, this is indicated in the display.

There is the d. of dice, as we have seen above, we can note the dice here and there will be a number from 1/6 to appear on the display. One press of the button is throwing again.

   Then there is the r. of random (random) in this position, the Dig-Dice will provide a random number from 0 / to 9.

  Then there is the G. guide (guide), in this mode you can use the Digi-Dice for a direction to determine this, go back completely random There are three possibilities, turn left, turn right and go straight.

Finally we have the F. flash (flash), this is a kind of running light, the display will continuously run in circles.

Except that the Digi-Dice a fun and decorative structure there are also countless fun games to play with. Using a number of printing a fun scavenger hunt in the neighborhood or in the forest and use it as a die in games.

Do you have other ideas please tell us!

Do you have comments or want to provide feedback on the Digi-Dice?

Do you have comments or questions about the Service Circuit JOTA-JOTI?



pointer3bDo you just hate when you can not find your tent in the dark. Or that the one leading Post-it just is not enough standing out among all other memo leaves? Then you really need the "Pointer"! The Pointer is a a running light that turns itself On in the light or in the dark.

The speed of the running light, in the form of an arrow, is variable. By pointing the Arrow anyone can draw the attention to something important. But you can also take off for a trip in the dark: Hang the pointer on an inconspicuous area. If a flashlight is shone, the Pointer work and you know which way to go (just follow the arrows !).

Of course you can also use the indoor Pointer: Hang it next to your own bedroom door and at night you can always find your own room back! Have you become very enthusiastic of soldering: Three pointers form a perfect circle!

The kit is powered by a 9V battery and will cost around 4.50 Euro go

You can order your Pointers NOW
