Compact 3×AA to 200–400 V DC Boost Converter Prototype with Integrated Digital Display
Budget: $30 – $250 USD
The immediate goal is a compact, battery-powered prototype that turns three AA cells into an adjustable 200 – 400 V DC output. An off-the-shelf DC-DC boost module with an LED/LCD digital display converter module is fine—what matters is reliability, efficiency, and a small footprint.
Key points you should know up front
• Input: 3 × AA (alkaline or NiMH)
• Output: 200-400 V DC adjustable
• Display: LED/LCD continuously reporting
• Form factor: pocket-sized if possible
Deliverables for this first phase
- A fully assembled, tested prototype
