This is a microwave with every part that a real microwave has, from a magnetron to a power chord. It is made to immitate a real, functional microwave.

Diyas are the heart of major Indian festivals, most notably Diwali, the "Festival of Lights." Lighting rows of diyas during Diwali symbolizes the victory of Lord Rama over Ravana and the welcoming of prosperity and Godess Lakshmi (the goddess of wealth). Tired of oily Diyas? In this tutorial, I will show you guys how I created these super simple 3D printed Diwali Diyas which are safe, non greasy, reusable, easy to make and will last forever.

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.

Easy-to-build VFO (Variable Frequency Oscillator) that features a clear, touch-enabled circular display with retro-style virtual scales.

when using the 3D probe like WP500 , the user need to send Clamp-UnClamp command to the CNC macine in order to catch the probe. But if the controll PC is far from the machine it is difficult to hold the probe and insert it manualy to the router, and send the command to clamp the probe. I use small device M5Stack core, that attach to the machine , and it connect to the CNC by the wifi network and carvera tcp protocol for MDI commands. by using the 3 M5stack buttons i can send commands directly to the CNC.

Project #16: Sound – Sound Sensor – Mk28

This project presents a hand blender designed and modeled in SolidWorks.The primary goal of this design is to demonstrate how a simple mechanical system can successfully perform its intended function while providing high efficiency and significant energy savings. Although the blender is based on a basic mechanism consisting of only two gears, it achieves effective mixing performance and stands as a clear example of how simplicity in design can lead to reliability, durability, and sustainability. The blender operates using a two-gear transmission system that transfers rotational motion from the motor to the blade assembly. This simple gear mechanism was intentionally selected to reduce mechanical complexity, minimize friction losses, and improve overall system efficiency. As a result, the blender can mix dense or viscous materials efficiently without requiring high power consumption, which directly contributes to electric energy savings.
