1. Getting Started & System Navigation

PREVIX ELTECH SOLUTIONS is an advanced engineering platform founded by Mr. Pritam Prashant Chaudhari in Pune, Maharashtra. The system unites commercial hardware distribution, academic publications recognized at Fergusson College, hardware design calculators, laboratory video streams, and AI-powered schematics assistance into a unified portal.

Theme Switching

Toggle between Light mode and Dark mode using the crescent moon/sun icon at the top-right of the navbar. Your preference is persisted in browser storage.

User Authentication

Register with a 10-digit mobile number and secure password. Receive an automated welcome & login security confirmation email whenever you log in.

Session Telemetry

While logged in, your active uptime is dynamically calculated and synchronized to the database via secure 30-second heartbeat telemetry.

2. Products Catalog, Multi-Image Viewer & Cart

Explore industrial IoT controllers, smart switchboards, and STEM hardware modules with real-time stock statuses.

How to Search & Filter Products
  1. Visit Products from the main navigation.
  2. Use category pills (e.g. Embedded Systems, Smart Home, STEM Kits) to isolate product types.
  3. Type keywords, SKU codes (e.g. PRX-ESP32), or features in the instant search box.
  4. Click "View Specifications" to open the full product datasheet page.
Multi-Image Gallery & Cart
  • On product detail pages, click any thumbnail in the gallery to inspect high-resolution PCB zoom views.
  • Click "Add to RFQ Cart" to stage items. Open the cart drawer anytime to verify GST taxes, itemized subtotals, and volume discounts.
  • Click "Download Datasheet (PDF)" to inspect electrical ratings, pinouts, and register maps.

3. Turnkey Engineering Projects & Bill of Materials

Learn how to inspect modular IoT architecture, hardware zero-cross detection schematics, and solar MPPT trackers.

Step-by-step Project Inspection:

1. Go to Projects to view tested prototypes.

2. Click any project card (e.g. Modular IoT Smart Automation Hub) to view its working principle, FreeRTOS architecture, and Bill of Materials (BOM) with quantities.

3. Use the "Live Demo" link or "Schematic Diagram" button to inspect Altium/KiCad circuit representations.

Includes Full Component BOM & Microcontroller Wiring

4. Interactive Engineering Calculators & Circuit Solvers

PREVIX includes 10 precision hardware tools designed to eliminate calculation errors during breadboard assembly.

Solver Name Formula / Standard Required Inputs Output Result
Ohm's Law Solver V = I × R, P = V × I Any 2 values of Voltage, Current, or Resistance Missing electrical parameters + Power consumption in Watts
Resistor Color Code EIA Standard RS-279 Select 4 or 5 color bands from dropdowns Total Ohms, multiplier scale (Ω, kΩ, MΩ), and ±% tolerance
555 Timer Astable Frequency f = 1.44 / ((R1 + 2*R2) * C) Timing resistors R1, R2 and capacitor C1 Oscillation frequency in Hz/kHz, period, and duty cycle %
Voltage Divider Vout = Vin × (R2 / (R1 + R2)) Input voltage Vin, resistor R1, and resistor R2 Output voltage Vout + loaded divider ratio
LED Series Resistor R = (V_sup - V_led) / I_led Supply voltage, forward voltage drop, and operating mA Recommended resistor value (Ω) and minimum power wattage (W)
PCB Trace Width IPC-2221 Standards Continuous current (Amps), temp rise (°C), copper oz Minimum trace width in mils and millimeters for internal/external layers

5. Video Laboratory & Bench Test Demonstrations

Access video walkthroughs directly on Videos.

Category Filtering

Filter by Embedded & IoT, Home Automation, STEM Kits, or Circuit Labs using quick pills.

Zero-Distraction Player

Clicking any video card launches an ultra-responsive 16:9 modal player with duration, view count, and technical bench notes.

Admin Video CMS

Administrators can publish YouTube streams or upload direct video files from disk via the admin control center.

6. PREVIX AI Engineering Assistant & Gemini Integration

The floating AI Assistant (robot icon at the bottom-right corner) provides real-time engineering answers for schematics, firmware code, and hardware selection.

Operational Rules & Limitations:
  • Character Limit: To ensure high precision and avoid buffer overruns, questions are capped at 500 characters per prompt.
  • Rate Limiting: Each client IP is permitted up to 15 queries per minute to protect server resources and maintain high responsiveness.
  • Google Gemini API Key: Click the ⚙️ icon inside the AI drawer to supply your own Google Gemini Key. If no key is set, the assistant automatically utilizes the built-in PREVIX Neural Core Engine for hardware answers.
  • Sample Questions: Try asking: "Calculate series resistor for 3.3V LED with 5V supply" or "Explain ESP32 dual-core FreeRTOS task pinning".
