Professional RF jammer with RF VCO and power RF amplifier
This project contains a Spice model for the popular NE555 timer IC, which is widely used in electronic circuits for generating accurate time delays or oscillations.
⌛ Control a relay connected device for a period of 1 to 100 seconds using a 555
Implemented a smart glasses project for the visually impaired, using advanced IoT technologies without Arduino. The system offers real-time feedback and navigation assistance, with comprehensive documentation and code available. Aimed at enhancing accessibility and independence.
MCU-less analog biomimetic bat flapping-wing robot with segmented wing driving
NE555 timer was launched in 1971 and has a history of 50 years. It is easy to use, stable and cheap, so it is still widely used, and its output in 2003 was 1 billion. Now I use NE555 to make timers. Most of the control parts of electronic door locks use this circuit. The timing method is very simple, 1.1 x RC, which is not very accurate compared…
When people go on vacations or are not present at home for a long period of time, they forget to water their plants. This project is an excellent solution for such problems, so plants can be watered automatically, without any human interference.
A laser-based intruder alarm circuit that triggers the buzzer and LED when the laser beam is interrupted.
Several circuit examples supporting the LCD displays (HITACHI HD44780 modules: 1) LCD1602A, v3, 2) LCD1602A, v3, with the PCF8574A chip providing I2C input and 3) LCD2004A, v1.3, with the PCF8574A chip providing I2C input) and OLED displays (JMD 0.91A and JMD 0.96A-2). Projects require SDCC to compile.
A high efficiency inverter that converts 12V DC into 220V AC using an NE555 timer, push pull MOSFET switching and a step up transformer. Designed and simulated in Proteus, then built and tested as hardware for the Electronic Devices and Circuits CEP at Bahria University.
Luminous Touch Toy made with NE555 IC & a piezo-electric sensor, with auto-off functionality.
