Neural Network KNN — Road Surface Condition Classification
AI & Machine Learning
Neural Network KNN is a machine learning project designed to determine road surface conditions based on accelerometer sensor data. The model uses K-Nearest Neighbors (KNN) to classify road states by analyzing datasets obtained from the Z-axis accelerometer indicator.
This solution can be applied in vehicle telemetry, road quality monitoring, and intelligent transport systems.
… How It Works
Sensor data collected from an accelerometer is processed and used as input for the KNN model. By analyzing vibration patterns along the Z-axis, the algorithm identifies and classifies the current road surface condition.
The model is trained on prepared datasets and can be adapted to different vehicles or sensor configurations.
Key Features & Capabilities
Road Surface Classification Detects and classifies road conditions based on accelerometer data.
KNN-Based Machine Learning Model Simple, effective, and interpretable approach for sensor data classification.
Z-Axis Accelerometer Analysis Focuses on vertical vibration data for accurate road condition detection.
Extensible Data Pipeline Easily adaptable to new datasets or sensor inputs.

Flashbots Transaction Sender — Private Ethereum Transaction
Cryptocurrency & Blockchain
Flashbots Transaction Sender is a Python-based tool for sending Ethereum transactions directly through Flashbots, bypassing the public mempool and protecting transactions from frontrunning and MEV attacks.
The script uses Web3.py together with the Flashbots API to submit transaction bundles straight to block producers, increasing execution reliability for sensitive or high-value operations.
… How It Works
The sender connects to the Ethereum network via an Infura RPC endpoint and submits transactions as Flashbots bundles. Instead of exposing the transaction to the public mempool, it is delivered privately to miners, reducing the risk of frontrunning.
The tool continuously monitors transaction inclusion and automatically adapts its strategy if execution fails.
Key Features & Capabilities
Web3.py Integration Connects to Ethereum nodes using Infura RPC for reliable network access.
Flashbots Bundle Submission Sends transactions directly to miners, bypassing the public mempool.
Dynamic Gas Fee Adjustment Automatically increases gas fees to improve inclusion probability.
Transaction Inclusion Monitoring Verifies whether the transaction has been mined and included in a block.
Automated Retry Logic Retries failed submissions with progressively adjusted gas parameters.
Use Cases
MEV-sensitive transactions
High-value Ethereum operations
Arbitrage and DeFi automation
Frontrunning-resistant contract interactions
