Analog tone synthetizator based on a 555 timer meant for STEM education.
Tone o mat is an open-source printed circuit board by Vedatori, from the Vedatori/Tone-O-Mat repository on GitHub. It is a 2-layer board of 193 × 81.9 mm with 133 parts on 46 nets, routed with 498 tracks and 69 vias.
It is built around the NE555PS and BC547. Its parts include 82 resistors, 20 connectors, 13 capacitors, 3 diodes and 2 ICs.
Tone-O-Mat je analogový syntetizátor vytvořený pro Letní robotický tábor 2023 organizovaný spolkem Vědátoři. Jedná se o stavebnici založenou na 555 timeru určenou pro vzdělávání v oblasti STEM s reproduktorem nebo výstupem pro audio-jack. Stavebnice se skládá ze dvou hlavních částí - plošného spoje osazeného elektronickými součástkami a dřevěné krabičky. Tuto stavebnici účastníci tábora obdrželi k montáži. Hlavním cílem bylo zdokonalit dovednosti pájení a zručnost v práci se dřevem. Z připravených dřevěných dílů si účastníci sami sestavili a slepili krabičku. Poté se pustili do pájení všech součástek na plošný spoj. Měli možnost volit mezi tradičním pájením THT a náročnějším zapájením SMD součástek. Tento projekt byl koncipován tak, aby byl přístupný jak úplným začátečníkům v pájení, tak i těm s více zkušenostmi. Po dokončení stavebnice mohli účastníci na syntetizátoru hrát jako na malém klavírku.

Tone-O-Mat is an analog tone synthesizer designed for Summer robotics camp 2023 (cz) organized by Vědátoři team (cz). It is an electronic kit based on a 555 timer meant for STEM education, with speaker or audio-jack output. It is composed of two main parts - a printed circuit board with electronic components and a wooden enclosure. Participants at the camp received this kit for assembly. The primary objective was to enhance soldering skills and proficiency in working with wood. From the pre-cut wooden pieces, participants assembled and glued the enclosure themselves. They then proceeded to solder all the components onto the printed circuit board. They had the option to choose between traditional THT soldering and the more challenging SMD soldering. This project was designed to be accessible to both complete beginners in soldering and those with more experience. Upon completing the assembly, participants could play the synthesizer as a miniature keyboard.
The schematic was customised from the schematic found at https://gr33nonline.wordpress.com/2018/04/25/stylophone/

It measures 193 × 81.9 mm and has 2 copper layers, 1.6 mm thick.
133 parts, built around the NE555PS and BC547. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
From the Vedatori/Tone-O-Mat repository on GitHub, at the commit this page was made from: the board is Electronics/tone-o-mat.kicad_pcb and its schematic Electronics/tone-o-mat.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Its repository states no licence, so its author keeps all rights: ask Vedatori before reusing the design.
