Makita battery resetting & balancing
We inspect compatible Makita battery packs, reset the protection electronics where possible, and balance the cells during servicing.
01 / In development
A compact measurement tool for the camera bag
This project explores a dedicated light meter built around the ESP32-C6. The goal is a focused, practical device that helps photographers read the scene and make exposure decisions without reaching for a phone.
From electronics and firmware to enclosure and user experience, the project brings Nikitron's end-to-end product development approach into one small instrument.

03 / Project focus
Hardware with a clear job
Light measurement
A dedicated workflow for reading the available light and turning it into useful exposure guidance.
ESP32-C6 platform
The project uses the ESP32-C6 as the foundation for connected, capable embedded product development.
Built as a product
Electronics, firmware, industrial design, and usability are considered together from the first prototype.

RTC GPIO stays powered during deep sleep for the internal pull-up.
| Signal | Connection | Configuration |
|---|---|---|
| I2C SDA | GPIO 19 | 100000 Hz |
| I2C SCL | GPIO 18 | |
| Wake button | GPIO 3 to GND | Normally open |
| OLED address | I2C 0x3C | 7-bit address |
Sleep wake: the RTC GPIO domain stays powered so the internal pull-up remains active during deep sleep. No external pull-up is required.
Timing: hold the button for 1200 ms to trigger sleep behavior; release stability is 300 ms.
05 / Development path
