README
README.mdFancyLight
FancyLight - an LED lamp powered by a Li-Ion battery, which can be found in used electronic cigarettes. It charges via a micro USB connector and is turned on and off using a touch button. A simple project to learn how to work with the TP4056 battery charging controller, a step-up DC-DC converter based on the SB6286 for powering LEDs, a touch switch controller based on the TTP223-BA6, as well as battery protection elements based on the DW01-P and dual MOSFET 8205A.
A touch switch controller is assembled on a separate PCB to improve touch sensing reliability.
TODO
- Fix schematic and PCB:
- Remap MCU pins to use benefits of builtin PWM generator
- Fix auto-on on charging issue: add LDO for sensor and MCU, decoupling capacitors
- Replace MURATA coil with some more common analog
- Rework ISP connector so it compatible with programming clip, place it near the edge
- Make 4 layers stackup
- Update BOM and placement files to automatically mount
- USB-C connector
- LEDs
- Inductor for Step-Up converter
- Replace resistor on SENSE pin to 10k - 100k
- Design mounting hole for PCB itself
- Fix enclosure
- Design mounting for the PCB for easier assembly
- Fix the depth of mode selection pocket
- (Minor) Update schematic and PCB
- Introduce nRF module for BLE
- Add wireless charger receiver as an alternative to USB-C

Questions
How big is the FancyLight V2 PCB?
It measures 40 × 40 mm and has 2 copper layers, 0.65 mm thick.
What parts does the FancyLight V2 use?
52 parts, built around the ATTINY44A-MU, SYN480R, SB6286 and TP4056. 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.
Where can I download the FancyLight V2 KiCad files?
From the Glebka/FancyLight repository on GitHub, at the commit this page was made from: the board is FancyLight-V2.kicad_pcb and its schematic FancyLight-V2.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the FancyLight V2 design in my own project?
Its repository states no licence, so its author keeps all rights: ask Glebka before reusing the design.
