XRC PRO is a powerful, open-source RC transmitter and receiver system using STM32 and NRF24L01. It features real-time control.

A replacement PCB for Hori Pad Mini controllers supporting software calibration & Hall Effect sensors.

This project aims to accelerate the process of identifying soil density values from the subgrade, subbase, and base course layers by integrating vibration, speed, and acceleration sensors connected to an Arduino Mega 2560 microcontroller. The data generated enables real-time monitoring and adjustment during the compaction process in accordance with SNI (Indonesian National Standard) 1738-2011.

I am Abdullah, a mechanical engineer specializing in high-quality CAD modeling and design. This single-seater Formula Student style race car showcases my skills in creating precise, functional, and visually appealing models. Featuring a lightweight tubular chassis, ergonomic bucket seat, aerodynamic rear wing, and detailed suspension and drivetrain systems, it demonstrates both technical accuracy and engineering creativity. I provide CAD modeling, 3D rendering, and manufacturing-ready drawings for automotive, mechanical, and industrial projects. My focus is on precision, practicality, and performance, turning concepts into professional, manufacturable designs that exceed expectations.

WiFi-Enabled, modular prototyping platform for creating and testing electronics projects with ease.

This project aims to develop a real-time monitoring system for important water quality parameters such as temperature, turbidity (TDS & turbidity), and pH. The device utilizes sensors such as DS18B20, SEN0244, SEN0189, and pH 4052c, integrated with a WiFi-based Robotdyn Arduino Uno microcontroller, and displays data in real-time via the IoT platform Thinger.io. This system not only displays data on an LCD screen, but can also be accessed from anywhere via a cloud dashboard, and data can be downloaded at any time. Testing was conducted over 7 days and the results showed a fairly good level of accuracy and precision, as well as compliance with the BBPBAT Buleleng koi pond water quality standards. Perfect for those interested in IoT, aquaculture, agricultural automation, or electrical engineering thesis projects! ???? Jangan lupa like, follow, dan comment..

A simple but very useful Zener diode tester

This build integrates an RTL-SDR v3 (RTL2832U+R820T2) covering 500 kHz - 1.766 GHz, paired with a 100 kHz - 2 GHz, 30 dB LNA powered by an internal 5 V → 1.2 - 24 V DC converter. A second RTL-SDR DAB/DVB receiver (RTL2832U+FC0012) covering 45 - 930 MHz, feeds into the USB 3.0 hub that forms the system’s primary data bus. A M8N-type GPS USB module supplies GNSS reception on L1 band (1.559 - 1.610 GHz) along with a PPS output for precision timing. The build also incorporates an EvilCrow RF v2, using a Wi-Fi enabled ESP32-PICO-D4. The microcontroller drives two CC1101 transceivers on 300 - 348 MHz, 387 - 464 MHz, and 779 - 928 MHz, as well as a NRF24L01+PA+LNA (GT24) module for 2.400 - 2.525 GHz operation. External antennas are connected through BNC, SMA, and RP-SMA ports grouped on one side of the device. The ruggedized design and weather-sealed connectors ensure reliable radio reconnaissance in the field.

R4TKN Deauther transforms the Ai-Thinker BW16 (RTL8720DN) into a dual-band 2.4/5 GHz Wi-Fi security lab tool, simulating disconnection events to audit and harden networks—featuring a portable, TFT-driven UI for authorized testing only.
