"Software engineer Alastair Roberts builds Alma, a 3D printed synthesizer for toddlers that lets young users produce and play child-friendly electronic music. Complete with an onboard sound module and a built-in speaker, the musical toy can play sounds without connecting to a computer or external equipment. The design includes several control knobs for tempo, volume, scale, pitch, and instrument type, allowing the young users to change how the loop behaves."
"When a slider is moved up, the pitch becomes higher, and when it is moved down, the pitch becomes lower. The loop repeats continuously, so the user can move the sliders at any time to change the sound. The internal electronics are mounted on a custom printed circuit board, and the outer shell is 3D printed."
Alma is a 3D-printed synthesizer for toddlers that produces child-friendly electronic music using an onboard sound module and built-in speaker. The device includes knobs for tempo, volume, scale, pitch, and instrument type, plus an OLED screen that shows visual feedback and a small animated panda indicating notes. Four sliders control individual notes in a continuous four-step loop, allowing pitch changes in real time as the loop repeats. The internal electronics sit on a custom printed circuit board while the shell is 3D printed and colored pink. The project originated from a Montessori activity board and served as a learning experience in microcontrollers, PCB design, and CAD.
