Between 2012 and 2013, Raúl Bartolomé co-owned Janty, Ltd. and directed the development of the MiD One — an electronic cigarette system that combined hardware, PC software, and a web portal. The MiD was the first electronic cigarette to introduce vaping profiles: editable, visual timelines that allowed users to program the dynamics of each puff with precision.
This innovation, protected by patents in the US and EU, gave users unprecedented control over voltage, power, and even LED color throughout a 0–12 second puff. The MiD was launched in 2014, rapidly attracting attention in the market and soon imitated by competitors in China.
Three Integrated Products
The project consisted of three interconnected elements:
1. Electronic Cigarette
The MiD required complete electronic product development. At its core was an NXP Cortex-M3 microcontroller, supported by SPI Flash, MOSFET power drivers, shunt amplifiers, regulators, and an RGB LED system. Firmware was developed in C with Keil tools, using an RTOS and optimized libraries. The device featured robust protections (battery, thermal, short-circuit, overpower), full monitoring (battery status, atomizer resistance, temperature), and a proprietary file system designed for efficiency within limited memory resources. Mechanical design, executed in SOLIDWORKS, ensured precision assembly and durability.
2. PC Application
Developed in C# with Microsoft Visual Studio, the multi-threaded application allowed users to configure devices, upload/download vaping profiles, update firmware, monitor real-time data, and manage licenses. It also connected to web servers, linking the device to a broader digital ecosystem. The interface supported detailed statistics, history of puffs, error logs, and personalized settings — making it both a control center and a gateway for customization.
3. Website and Licensing Portal
The MiD ecosystem included two web platforms:
- A Joomla!-based user interface, providing social features and a purchasing process for licenses.
- A CodeIgniter-based backend for license management, unique identifier generation, and integration with end-of-line testing.
Together, these sites allowed Janty to monetize advanced features while creating a community-driven ecosystem around the product.
Technical Specifications
The MiD One supported both single and dual-battery configurations, delivering up to 25 W of power and 8 V of output. Users could define up to four vaping profiles, each editable at 0.1-second intervals, with controls over voltage, wattage, LED color, and other thresholds. Protections were extensive, including reverse polarity, thermal monitoring, and atomizer safety. Despite its sophistication, the device was compact and lightweight (116.6 mm length, 19.4 mm diameter, 40 g).
Raúl’s Contribution
As co-owner and chief engineer, Raúl led the complete system development: from concept to hardware, firmware, software, and web integration. He not only invented and patented the concept of vaping profiles but also coordinated engineering teams across hardware, software, and digital platforms. His dual role as executive and senior engineer ensured that the MiD combined technical innovation with a viable business model.
Legacy
The MiD One was the flagship product of Janty, Ltd., representing a major innovation in the e-cigarette industry. It introduced concepts that later became industry standards and highlighted how integrated ecosystems (device + PC + web) could reshape consumer experiences. The project demonstrated Raúl’s ability to lead multi-domain innovation, bridging electronics, software, and business strategy in a fast-moving consumer electronics market.
