Here is information on how to build a diy time lapse circuit which will allows a camera to automaticly take photos between a certain time interval. Those photos then can be then to create time lapse film. It is used in this circuit a 2, 5 to 3, 5 stereo jack adapter which will be connected to the camera, a 3, 5 stereo jack cable and 3, 5 f

emale jack connector which will be connected to the circuit with wires. To test this out before assembling the circuit, connect everything and touch with a wire the ground of the female connector to one of the its tips and the camera should either focus or shoot (more info in ). It is possible to use only a 2, 5 cable by dismantling it and solder the wires directly to the circuit. The main part of this circuit is the 555 timer IC which will control the time in the circuit. The 555 will be in astable (or oscillator) mode which will produce an output pulse on pin 3 during a certain amount of time, stop it during a certain amount of time and will keep repeating these two states. To prevent the camera to keep shooting during the period the circuit is outputting the pulse, it is necessary to disable the camera`s continuous shooting option so that camera only shoots one shot when the circuit starts to output the signal. The time interval between shots will be one cycle of these two states, in another words, it will be the the amount of time that circuit outputs the pulse plus amount of that time that the circuit pauses before it starts outputting the pulse again. All you need now is to connected the battery as seen above and the circuit should be working. It is wise to add and ON/OFF switch to the battery and LED to check if the circuit is on or off. This calculator will calculate the value of the R2 resistor necessary to...
This project fits more for custom made battery casing that can have more space to hide things inside. This switch with few alterations can be used for any other project as well but is designed based on e-bike needs! This project use a clever functionality of....
The circuit described here uses ultrasonic oscillations and operates based on the propagation velocity of these oscillations in the air. Thus, we can easily determine the distance of two points if the time within which the wave travels this distance is....
Sometimes the precious metals are hidden too deep and are not detected except with complicated devices. In many cases, however, small pieces of precious metal buried near the surface can be detected by relatively simple means. Everyone is very attractive to....
Many times for various reasons we forget or can not water the plants that we have in our homes. And many humidity sensors units just notify us with a beeping sound or with a flashing light, that the pot needs watering. But what if we are away from home? This....
The principle behind a metal detector is really very simple. Proof of this is the circuit that follows, in which it proves that the construction of a metal detector can be done in the minute, with few components that we find very easily everywhere. With the....
The sub-harmonic bass generator is a sound producing unit for guitars. The sound it produces looks very much like that of the bass guitar. The octave generator is sometimes quite unusual since it does not produce any of the usual ways of coloring the sound,....
In the past the sounding (sea bottom measurement) was done with the "bullet", that is, with a heavy lead object that the seamen plucked into the sea hung from a calibrated rope. As soon as the "bullet" reached the bottom, the depth appeared directly from the....
This Amplifier was designed to have the following specifications: Distortion less than 0.1% at full power of 100W even at 20KHz. Power has to be attributed to an extended bandwidth. The output transistors must be protected against short circuits. The power....
A series of LEDs serve to alert the gardener when plants need water. Using two conventional digital integrated LEDs and a series of LEDs, we make a very useful device for gardening. The device detects the amount of water in the pot and alerts the grower.....
