Affordable, Safety-Isolated Power Supply for Bio-Hacking & Student Projects
The post talks about a student's EMG (Electromyography) project. A comment raises an important safety concern: "Be very careful with how you supply this... Either use a medical-grade power supply (hah, super expensive) or use batteries...". This highlights a significant challenge for students and hobbyists working on bio-signal projects (like EMG, ECG, EEG) that involve direct connection to the human body—the high cost of safe power supplies.
Product Opportunity: An affordable, dedicated, and safe power supply module for bio-signal acquisition projects.
Product Suggestion: A compact power supply module specifically designed for hobbyist and student bio-signal projects (like EMG, ECG, EEG). This module could feature:
- Battery-Powered Option with Built-in Isolation: A module that runs on standard rechargeable or non-rechargeable batteries (e.g., Li-ion, AA) and incorporates robust electrical isolation (e.g., using isolated DC-DC converters or optical isolation on any data lines if the module also includes signal conditioning) to ensure no direct path from mains power or unsafe ground loops to the user. It should also include necessary battery management features like overcharge/discharge protection.
- Medically-Inspired Isolated AC-DC Adapter: A low-cost AC-DC power supply unit that, while not necessarily meeting full medical-grade certification (which drives up cost significantly), employs key safety principles like high levels of input-to-output isolation (e.g., reinforced insulation, high isolation voltage rating), low leakage current, and potentially current limiting, specifically designed for powering circuits connected to the human body in non-clinical, educational, or hobbyist settings.
- Clear Safety Indicators: Visual indicators (LEDs) for proper grounding (if applicable), isolation integrity, or battery status.
- Standardized Output: Provides common low voltages (e.g., +5V, +/-5V, 3.3V) suitable for op-amps and microcontrollers used in such projects.
- Educational Material: Accompanied by clear documentation on safe usage, principles of electrical isolation in bio-potential measurements, and limitations.
Expected Benefits:
- Enhanced Safety: Greatly reduces the risk of electrical shock or other hazards for students and hobbyists working on projects directly connected to the human body.
- Increased Accessibility: Makes bio-signal acquisition projects more financially accessible by providing a significantly cheaper alternative to expensive medical-grade power supplies.
- Simplified Project Development: Offers a plug-and-play (or easy-to-integrate) power solution, allowing users to focus on the bio-signal acquisition and processing aspects rather than complex and potentially dangerous power supply design.
- Peace of Mind: Reduces anxiety associated with using potentially unsafe power setups for sensitive applications.
- Fosters Innovation: By lowering the barrier to entry, it could encourage more experimentation and learning in the field of biomedical engineering and DIY bio-hacking.

My first project - An EMG (Electromyography) module

Hi everyone! I'm a second-year Electrical & Electronics Engineering student, and this is my EMG (Electromyography) sensor project, built as part of the Analog System Design course in my c

Yes I'll keep that in mind about socketing the ICs for prototypes, it certainly would make stuff easier to debug and replace. About the decoupling capacitors, I should have added them.

Nice neat work on the wire links too. May I ask what the type of wire you use is?
I've considered buying a pack of the breadboard

Edit: I think you did a nice job. Some constructive feedback:
What are you powering it with?
You should *never* attach a live circuit to a person if it isn't safety isolated. That means no

I used a battery powered dc supply to power this circuit, we were made aware of the precautions to take in case of such projects. So we were pretty careful about not harming anyone.
