e-bike that charges itself while driving

Designing an e-bike that charges itself while driving (i.e., regenerative charging or solar-assisted charging) under a ₹20,000 budget is extremely challenging but not impossible if done smartly with DIY parts , recycled components, and simplified design. Let’s brainstorm ideas and give you a working plan , with rough costs and steps. ⚡️ CORE IDEA: A low-speed e-bike (20–25 km/h) with self-charging via pedal generator + small solar panel + regenerative braking using hub motor – ultra-lightweight, DIY. 🔩 COMPONENTS NEEDED (Approximate Costs in ₹ INR): Component Description Estimated Cost Hub Motor (250W) BLDC hub motor with regenerative braking support ₹3,500 Controller (36V, Regen Support) BLDC controller with regen input ₹1,200 Battery (Lithium 36V 7Ah) Used/recycled battery from e-waste (buy/salvage) ₹3,000 Solar Panel (30W–50W) Mounted on bike body or rear ₹2,000 Pedal Dynamo Used as backup charging source ₹600 Chassis / Bicycle Frame ...

Create working car for 10000 , components and assembly

Creating a working car for ₹10,000 (~$120) that can travel across India or even the world is extremely ambitious. But if your goal is innovation, resourcefulness, and a radical prototype, here's a breakdown of how you might approach it creatively, legally, and functionally : 🔧 Concept: “Jugaad Nomad” – Ultra-Budget Travel Car ✅ Objective : Functional enough to carry 1–2 people. Moves reliably on roads at 25–40 km/h. Lightweight, serviceable, fuel-efficient, DIY-style. Base cost: ₹10,000 or less (excluding taxes or paperwork). 🚗 CORE DESIGN IDEAS: 1. Chassis & Frame Upcycle bicycle/scooter/moped frame or old three-wheeler base. Rickshaw chassis from scrap yards. Use welded square tubing or angle iron (cheap and strong). Option: Reuse scrapped Tata Nano or Maruti 800 body shells . 2. Engine Options Option 1: 2-stroke used moped/scooter engine (Bajaj Chetak, Hero Honda CD100) from junkyard – ₹1,500–₹3,000. Option 2: Electric cycle kit (250W BLDC motor ...

Create a working car for 10000 RS

Creating a working car for ₹10,000 (~$120) that can travel across India or even the world is an extreme challenge—but not impossible if you think creatively and reduce the concept to essentials . Here’s a brainstorm of practical, innovative, and alternative ideas to help you move toward this vision. 💡 BASIC CONCEPTS Before diving into ideas, let’s clarify: ₹10,000 is not enough for a traditional car, but it can build an ultra-minimalist vehicle . Think beyond fuel cars: electric, pedal, solar, or hybrid . Focus on DIY, recycled materials, and local innovation . 🔧 1. Recycled Electric Rickshaw Base Buy old/damaged e-rickshaw parts from scrap dealers. Build a 3-wheel EV with: Salvaged battery packs (old inverter batteries or laptop cells) Scrap metal chassis Bicycle wheels or small scooter tyres Estimated Cost Breakdown: Item Estimated ₹ Scrap e-rickshaw frame 2500 Battery (scrap/used) 3000 Motor (DC, used) 2000 Wheels and tyres 2000 Mi...
