Nano Cochlear Implant Sim Kit with Arduino Nano + HC-05
Nano Cochlear Implant Sim Kit with Arduino Nano + HC-05
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
This advanced kit guides you through building a real-time cochlear implant simulation. The MAX9814 microphone captures ambient sound, feeding an 8-band filter bank that splits audio into frequency channels. The Arduino Nano then digitizes these bands, encodes stimulation timing patterns, and streams the data wirelessly over HC-05 Bluetooth to your phone—mimicking the signal processing front-end of a modern neural prosthesis.
What You'll Build
You'll assemble a wearable prototype that converts acoustic signals into stimulation vectors. The complete system uses eight LM358 op-amp stages to create tuned filters, a DS3231 RTC for precise timestamping, and a LiPo battery for portable operation. The final output appears on a custom BLE app, allowing you to analyze how each frequency band contributes to the perceived sound map.
What You'll Learn
- Designing an 8-channel active filter bank with LM358 op-amps
- Real-time audio signal acquisition using MAX9814 and Arduino ADC
- Encoding sound into neural stimulation timing for cochlear models
- Implementing BLE data streaming from Arduino Nano to mobile devices

Who This Kit Is For
Engineered for final-year B.Tech ECE/EEE students, M.Tech biomedical researchers, and Smart India Hackathon health-tech participants. It aligns with IIT, NIT, VIT, and BITS Pilani project curricula, as well as ATL Tinkering Labs running advanced neuroprosthetics workshops. If you are exploring signal processing, neural coding, or wearable medical devices, this kit bridges theory and implementation.
Built and Backed by Compoden
Every Compoden kit ships with an AI build companion trained on this exact project — accessible via a QR code on the box, with WhatsApp and email backup. We've spent 10 years building projects for makers, schools, and institutions across India. If a part fails because of a manufacturing defect, replace it free within 7 days.
What if I get stuck during the build?
The AI companion provides per-step debugging; if you need human help, WhatsApp support from our Bengaluru team is included with the kit.
Can I visualize the stimulation patterns on a phone?
Yes, the HC-05 BLE module transmits encoded frequency-band levels to a sample Android app, ready to display real-time spectrograms and spike patterns.
Does this kit include actual electrode stimulation hardware?
No—it simulates the signal processing pipeline. Electrode-nerve interface components are not part of this kit, making it safe for academic and prototyping use.
Is prior soldering experience mandatory?
Strong soldering skills are required; the kit includes a soldering iron and involves assembling SMD capacitors and op-amp filter arrays on prototyping PCBs.
MAX9814 mic feeds 8-band filter bank. Nano encodes sound to stimulation patterns. Output over BLE to phone.
