On the product:
An electronic kit for self-construction of a digital FM radio transmitter that also serves as a wireless microphone

From this circuit you can build a real digital FM radio transmitter and actually transmit to your radio as a wireless microphone. After you have built the circuit, connect a microphone to the dedicated connection in the assembled kit (a standard 3.5 mm banana jack), tune in to any station on the home radio and search for the station on the transmitter by turning a potentiometer that controls the frequency.
As soon as you find the desired station, start talking into the microphone and you will hear yourself on the radio!

This kit is a creative kit for youth and children aged 10 and over and includes delicate work with a soldering iron to build and assemble a complete electronic circuit with components from the world of analog and digital electronics.
The electronics kit for children and youth allows them to build an electronic circuit of a real radio transmitter by themselves and provides them with both an experience of experimenting with real electronics as well as creation and delicate work that develops focus tolerance and deep concentration.

The kit includes all the electronic components required to build the kit – the kit includes resistors, capacitors, jock, relay, LED lights, electronic board, battery house and more…

The circuit operates on a voltage of 3-5 volts (battery house is attached, batteries are not included)
*In order to build the kit, you must equip yourself with a soldering iron and tin:
To purchase a perfect soldering kit
To purchase a USB soldering iron
to purchase tin

The circuit comes with marking the locations of the components on the board and a digital instruction booklet in Hebrew.
