LED torch using MAX660
This is a simple LED torch circuit based on the MAX660 integrated circuit from MAXIM semiconductors. The MAX660 is a CMOS monolithic voltage converter IC capable of driving three bright white LEDs connected in parallel to output pin 8. The...
ultrasonic transmitter circuit
The circuit utilizes a 555 timer integrated circuit (IC) configured as an astable multivibrator, which generates a continuous signal at a specific frequency as long as its reset pin (pin 4) is held high. The ultrasonic transducer employed in this...
simplest mains operated led flasher
The following mains-operated LED flasher circuit, which is essentially an astable multivibrator circuit, utilizes a diac and resistor arrangement to achieve an interesting wig-wag flashing effect with two LEDs. The circuit was shared by Mr. Vineesh, a dedicated follower of...
LED power supply
Efficiency can be increased by using a germanium transistor at the 33 ohm current sense resistor, and by using a proper torroid core in place of the crappy ferrite bead. Single AA cell powers two LEDs at constant current.
The circuit...
RC audio oscillator with 555
The transistor Q5 and the 1000-ohm resistor form the variable element necessary for controlling the frequency of the voltage-controlled oscillator (VCO) by limiting the charging current flowing into the 0.15 microfarad timing capacitor based on the forward bias applied to...
Fairy Flashing LED Lights
This simple and inexpensive circuit is not limited to Christmas use. It consists of two resistors, a small-signal transistor such as a BC547, and a flashing LED.
The circuit operates by utilizing a small-signal transistor, which acts as a switch to...
555 Music lantern controller circuit diagram
