Product Description
Unlock your productivity while mastering soldering skills with our Pomodoro Timer Solder Kit. Transform the work-rest productivity technique into a desk accessory you built yourself. Some of the popular Pomodoro intervals are 25-minute work with 5-minute rest, or 45-minute work with 15-minute rest. This Level 2 solder kit challenges intermediate makers to assemble a fully programmable timer featuring a four digit 7-segment display, RGB LED, and customizable buzzer alerts. Whether you’re a student studying in sessions, a professional managing work blocks, or a maker wanting to enhance your workspace, this kit combines practical productivity tools with hands-on electronics education.
Built around the RP2040 microcontroller and programmed in beginner-friendly MicroPython, this timer offers complete customization of work and rest periods in 5-minute increments. The WS2812B RGB LED provides instant visual feedback – red for work time, green for rest periods, and yellow warning when transitions approach. Four buttons control select/pause, reset, and time adjustment functions, different melodies you can select via jumpers ensure you’ll never miss a session change. The compact 7x7cm PCB design sits perfectly on any desk, requiring only USB-C power to transform your productivity workflow.
This kit perfectly balances practical utility with advanced learning, teaching professionals soldering techniques while creating a useful productivity tool. Complete open-source design includes schematics, code. KiCad files, and 3D-printable enclosure files, enabling unlimited customization and learning opportunities. Easily re-program this kit in MicroPython yourself! The comprehensive documentation guides you through each assembly step while explaining the electronics principles behind this timer system.
