Building an ESP32-S3-Based SR6 Clone with a Built-in Web UI

[Karasukaigan]

I’m planning to build an ESP32-S3-based device similar to the SR6 from scratch. The goal is to solve one of the biggest usability issues with TCode devices: they typically depend on desktop software or mobile apps before they’re usable. Both the 3D models and firmware will be redesigned from the ground up while remaining compatible with the TCode v0.3 protocol.

I previously created T-Code Controller, and I’d like to take the idea a step further. Instead of relying on external software, the TCode device itself would host a built-in web interface that can be accessed directly from any browser.

T-Code Controller — control your T-Code devices from any browser, no app to install

I built T-Code Controller, a firmware for the ESP32-S3 that turns it into a Wi-Fi web controller for T-Code compatible devices. [r_1] The problem I wanted to solve: Controlling T-Code devices usually means installing multiple apps on your phone or computer, with features scattered across different programs. There wasn’t a simple, integrated way to do it. What it does: T-Code Controller runs as firmware on an ESP32-S3 development board. You connect your T-Code device to the board’s USB-OTG po…

The web interface would integrate features such as:

• Device control
• A Funscript player
• A Funscript editor
• A serial monitor
• An achievement system
• And more

The end goal is a true plug-and-play TCode device: power it on, connect with a browser, and start using it immediately—no software or app installation required.
