Hi everyone,

I'm working on a battery-powered OECT-based ECG acquisition system for a research project and need to source the following components with a delivery timeline of approximately 2–5 days. I'm looking for reliable vendors/distributors that can provide genuine parts and reasonably fast shipping.

Main components:

• ADS1292R (Texas Instruments) – ECG Analog Front-End

• MDBT50Q-1MV2 (Raytac Nordic BLE Module)

• nPM1100-QDAA-R7 (Nordic Power Management IC)

• MCP4725 (12-bit I²C DAC) ×2

• OPA2333 (Dual Precision Op-Amp)

• OPA333 (Precision Op-Amp)

• INA180A1 (Current Sense Amplifier)

• USB Type-C Connector

• Li-Ion Battery Connector

• 2.2 µH Power Inductor (for nPM1100)

• Precision Resistors (0.1%)

• Standard 0603 Capacitors (100 nF, 1 µF, 10 µF)

​

Location: Jodhpur, Rajasthan,India

​

Could anyone recommend distributors or vendors that typically stock these components and can deliver within 2–5 days? Experiences with DigiKey, Mouser, Arrow, element14/Farnell, RS, LCSC, or local distributors would also be helpful.

Thank you.

Hi everyone,

I'm planning to design a PCB for a wireless wearable ECG device that can acquire ECG signals and transmit them to a computer or mobile phone.

I'm relatively new to biomedical PCB design and would like to understand the overall design process.

How would you approach designing such a PCB from scratch? What are the main blocks that need to be included, and what should I learn first before starting the schematic and PCB layout?

Any guidance, design flow, or resources would be appreciated.

Thanks!

Hi everyone,

I'm currently doing an internship at IIT Jodhpur and have been assigned a project related to Neural Networks and Image-Based Processing.

The challenge is that I'm a complete beginner in Machine Learning, Deep Learning, CNNs, and Computer Vision. Our mentors have provided several research papers, and our task is to understand them, explain their methodology, and learn how the techniques are applied in real-world image processing tasks.

We have only about 2 days to get a decent understanding of the topic before discussing it further.

Could experienced people suggest the most efficient learning path for someone starting from zero?

Some specific questions:

What concepts should I learn first before reading research papers?

Should I focus on Machine Learning basics first or directly start with Deep Learning/CNNs?

How do you read and understand research papers efficiently as a beginner?

What are the most important topics in image processing and computer vision that I should prioritize?

Are there any YouTube channels, courses, notes, or resources that can help me learn the fundamentals quickly?

My goal is not to become an expert in 2 days, but to understand enough to explain the papers and discuss the concepts intelligently.

Any advice would be greatly appreciated.

Thanks!
