Research Lab Kit 15 Quantum Random Number Generator
Research Lab Kit 15: Build a True Random Number Generator with Avalanche Noise on Raspberry Pi 5
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
Transform a Raspberry Pi 5 into a true random number generator using the avalanche noise of a reverse-biased BC547 transistor. This advanced research kit challenges you to harvest raw entropy, amplify and digitize the signal with precision electronics, then rigorously compare your hardware RNG against pseudorandom algorithms using the NIST statistical test suite ā exactly as done in modern quantum cryptography labs.
What You'll Build
A fully instrumented hardware entropy source that outputs cryptographically useful random bits. You'll capture the noise signal from a reverse-biased transistor junction, amplify it with an LM741 op-amp, sample it via the ADS1115 ADC, and process the raw data on the Pi 5. The project includes storing bitstreams on an NVMe SSD and running a complete NIST SP 800-22 test suite to validate randomness, finally pitting your hardware generator against Python's PRNG.
What You'll Learn
- Characterizing avalanche breakdown noise in a reverse-biased BC547 transistor
- Designing a low-noise analog front-end with operational amplifier gain stages
- Interfacing an I2C ADC with Raspberry Pi 5 for high-resolution entropy sampling
- Implementing and interpreting NIST statistical tests for true randomness

Who This Kit Is For
Ideal for B.Tech ECE/EEE final-year students working on cryptography or hardware security projects, researchers exploring entropy sources for QKD, and mentors guiding Smart India Hackathon teams in cybersecurity themes. The project aligns with advanced lab curricula at IITs, NITs, and BITS Pilani, giving students hands-on experience normally confined to dedicated research facilities.
Built and Backed by Compoden
Every Compoden kit ships with an AI build companion trained on this exact project ā 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?
Our AI build companion, accessible via QR code, has been trained on this exact noise generator circuit and software workflow. If you need human help, message us on WhatsApp for detailed guidance.
Do I need an oscilloscope to complete this project?
No, the ADC and Pi handle all signal capture. However, an oscilloscope (optional) helps visualise the noise waveform ā the build companion will suggest connections if you have one.
How do the statistical tests work?
The kit includes Python scripts to run the NIST test suite on both your TRNG output and Python's random module, generating clear pass/fail reports for monobit, runs, and other tests ā you'll learn what makes entropy truly random.
Can this kit be used for cryptography applications?
While the bit rate is low (around 1ā10 Kbps), the project demonstrates the principle of physical randomness suitable for generating seed values in cryptographic systems; it's an excellent educational foundation for QKD research.
Avalanche noise from a reverse-biased transistor generates hardware random bits ā statistical tests vs PRNG on Pi 5.
