Title: High Voltage Driver & Startup Circuit for Neon/Plasma Tube Lighting Description: I’m looking for an experienced electronics engineer to design a high voltage driver and startup circuit for a neon/plasma tube (LT‑2 or equivalent) used in a lighting project. The project involves DC-DC voltage conversion, microcontroller-based control, and monitoring for startup and full-power operation. Project Requirements: Input voltage: 12V–24V DC Output voltage: ~500V DC steady-state, with strike pulses up to ~600–700V Tube startup: low-light “warm-up” mode with gradual ramp to full brightness Microcontroller interface (ATmega328p) for: PWM strike control Voltage and current monitoring via ADC Optional 1” I²C OLED display for status Adjustable HV output via trim pot Optional brightness control via PWM pot Deliverables: Complete schematic (KiCad preferred) including: HV module, strike MOSFET, tube, series resistor, voltage divider, current sense, MCU, OLED interface Custom HV module symbol for KiCad Bill of Materials (BOM) Functional block diagram and documentation including net names and safety notes Recommendations for PCB layout and safety clearances (optional but preferred) Skills & Experience Required: High voltage electronics design (400–600V DC range) DC-DC converter design (boost/flyback) Experience with neon/plasma tube circuits or high-voltage lighting applications MCU interfacing (ATmega328p) Familiarity with KiCad or other EDA tools Knowledge of HV safety, isolation, and creepage Additional Notes: Safety is critical; this is a bench / lighting project, not industrial. Candidate should advise on resistor sizing, capacitor selection, and safe handling of HV circuits. Budget & Timeline: Flexible, to be discussed based on experience and deliverables.

Hello, I have reviewed provided file and can design the complete high-voltage driver and startup circuit for your neon/plasma tube project (~500–700V DC) using KiCad, including MCU-based control, voltage/current monitoring, and optional OLED interface. The work will focus on safe DC-DC boost/flyback design, strike pulse generation, warm-up ramp, and proper HV isolation. All work will follow IPC, IEC standards and DFM best practices. Following are the deliverables: • Complete schematic design in KiCad • Functional block diagram • Design documentation • Recommendations for PCB layout • Bill of materials I wanted to ask: • Should the HV output be adjustable over the full 500–700V range, or only fine-tuning via trim pot? I have 7+ years of experience in projects like: • High-voltage electronics design for neon/plasma lighting (400–600V DC range) • DC-DC boost/flyback converter design and HV MOSFET driver circuits Thank you for considering my proposal. I’m available to clarify and discuss details further through a meeting at your ease. Best Regards, Abubakar
