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.
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…
Several circuit examples supporting the following 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. Projects require SDCC to compile.
