The Theremin was the first music synthesizer. The Junior Theremin is our, smaller, version of that classic electronic musical instrument. As you move your hand towards and away from the wire aerial, the Theremin responds by changing the pitch of the note it is playing. It can play individual notes as well as varying the tone of a single note. How do you use the theremin? The wire aerial responds to the movement of your hand towards and away from it and changes the pitch of the note it plays, without actually being touched. Junior Theremin works in two modes – continuous and discrete. When you first connect the battery Junior Theremin is in continuous mode. Pressing both pushbuttons together switches between continuous and discrete modes. Discrete mode, as its name implies, plays individual or discrete notes rather than a continuously variable tone. Eight notes over a single octave are available. In discrete mode the two pushbuttons change the octave of the notes. The left-hand pushbutton (marked -) lowers the octave, and the right-hand pushbutton (marked +) raises the octave. The pushbuttons only change the octave so long as they are pressed. In continuous mode the pushbuttons have no effect. Downloads Manual

When playing a board game, do you find it annoying when you push away all the pawns with the dice? Or when friends try to cheat by manipulating the dice? With this soldering kit, this is a thing of the past. Instead of pressing a button, you activate this microprocessor-controlled dice by shaking. The 7 flashing LEDs run out slowly and the final combination is displayed flashing. The kit works with one CR2025 or one CR2032 button cell (not included). Downloads Manual

Looking for a fun DIY Christmas project? Assemble and program this extra-large Poly Reindeer figurine and make its LEDs shine all the colors of the rainbow! Ideal for both beginners and advanced makers! This educational and fun kit combines soldering and programming skills in one XL-sized project. First, you will need to solder some simple components onto the copper plated circuit board. The components include fancy RGB LEDs that have a special diffused effect. Once the soldering work is finished, you will be able to program the colors and light effects of the different LEDs thanks to the onboard Arduino Nano Every. The Arduino will be pre-programmed with some basic LED effects, so your kit will work once you power it with the included adaptor. Or you can choose to write your own code based on the available example code. Programmable add-ons The printed circuit board of this project is designed especially so you can add different add-ons. For example, add an OLED screen to display messages or program it to countdown the days until Christmas! Or add an IoT Tuya chip so your project can communicate with your smartphone. You can even add a sound microphone, motion sensor or light sensor.
