CAMJAM EDUKIT-2 Sensors (Thermometer)
2 Sensors
Having visited the Egham Raspberry Jam on a few occasions I decided to see if my 9 year old would be interested in having a go at Python and using the EDU KIT and learning how to read the temperature from the thermometer and convert it to both C and F on the screen.
Thermometer coding
This is the worksheet showing the circuit for the thermometer, the lights and buzzer are left on the board, but are not initially used or needed.
The above video shows the thermometer running and the output on the screen in C, holding it in my hands you can see the temp rise and then fall back to room temp
CAMJAM EDUKIT-2 Sensors (Lights and Buzzers)
2 Sensors
Having visited the Egham Raspberry Jam on a few occasions I decided to see if my 9 year oldwould be interested in having a go at Python and using the EDU KIT and learning how to control lights and buzzers and various sensors. After following the initial code We played around and made the lights flash on and off, one on two one etc and the busser. This is a great way to learn some simple python code and see it interact with physical components. Highly recommended!
Lights and Buzzers coding
This is the worksheet downloaded for the CamJam site above showing the circuit. The code can be downloaded or typed in from the sheet.
The Video above shows the 2 LED lights and the buzzer and what we did by playing around with the code to show various functions.

AMSAT UK Oscar Magazine publishes our July ISS success
Chertsey Radio Club
Hello, I am part of Chertsey Radio Club.
Over 3 weekends in July there were several amateur radio experiments run from the International Space Station and I would love to share with the BBC and the general public what has been happening, hopefully this will encourage some people to look and have a go at our hobby, or spark an interest in space or communications in general.
Chertsey Radio Club is also proud to be associated with AMSAT-UK, who help track monitor and support all things satellite related and keep the community updated with all the latest operating and technical data on the satellites.
Part-1
Firstly, on 5th July, The ISS crew were instructed to test out 2 cube satellites, Tanusha-1 and Tanusha-2, before deployment. The Tanyusha-YuZGU 1 and 2 (also TanyushaSWSU 1 and 2 or Tanyusha 1 and 2), also known as Radioskaf RS-6 and 7, are two small Russian experimental satellites, which are to be deployed from the ISS during a spacewalk. They were developed at the Southwestern State University (SWSU, YuZGU), Kursk The satellites will broadcast greetings messages in Russian, English, Spanish and Chinese. The test was to ensure the Satellites would both transmit their messages, so using the ISS onboard Amateur radio equipment, relay the messages from the satellite out on 144.800Mhz FM. Amateur radio operators around the world were given an opportunity to hear the messages and I could receive them on my radio set at home.
Part 2
On Saturday 8th July, being experimenters in radio communications, we were very lucky to be able to send voice communications via the International space station, whilst the satellites were being swapped over. The uplink was on 437.050Mhz (output of the Satellite) and downlink on 145.800Mhz I was very lucky to make an initial contact with another Amateur radio station in Spain EA4SG. On the second pass a few hours later, I could talk to Amateur radio operators in Spain, France and I also spoke to my friend in the UK Abdel (M0NPT) which was an exciting and amazingly rare opportunity.
Part 3
On the last weekend Amateur Radio on the
International Space Station (ARISS) celebrated its
20th anniversary – 20 years on both Mir Space
Station and on the ISS.
This organization helps to run and maintain
amateur radio on the space station, and set up
and run the contacts with many schools around
the world including Tim Peake’s Principia
mission when he spoke to 10 UK schools last
year.
As part of the celebrations the ISS sent a set of 12
images using slow scan television (SSTV), which
when heard on the radio sounds like the old fax
noises.
We were able to receive the sounds and
convert them into images when the ISS was in
range.
People all around the globe used simple
receivers along with mobile phones, raspberry
pi’s, computers and tablets to decode the images.
I was able to get all 12 of the images at home
and some of them are displayed here. the full
set can be seen here: http://chertseyradioclub.

I recorded a couple of the passes, so you can see
how this works, but the earliest in the UK was
23:23 and transmitted through into the early
hours of the morning, so we left the decoder
running and went to bed.
Best regards, M0JFP Chertsey Radio Club (MX0MXO)
