The camera and shutter control are completely self contained and can be used in any situation where you would like to take a number of photos automatically at a set interval in time. In this case it is for Kite Aerial Photography, but I have used this camera with an RC plane as well. I am sure you will come up with many more interesting applicatio

ns for this camera. I look forward to hearing how you use this design. The inexpensive LMC555 CMOS Timer IC can be configured as an astable oscillator. That is a fancy way of saying that it can close a switch every few seconds, open it again and repeat until the camera`s memory is full. In this case, at a resolution of 640x480, that is 180 pictures, or 15 minutes of photography. A more sophisticated intelligent shutter control which still requires no external power and only 2 wires to connect to this camera or any camera with similar features can be built using Texas Instruments MSP430 line of low power microprocessors. I have recently constructed a controller for the GoPro HD Hero camera. GoPro HD Hero Controller. As the Mustek Mini 3 camera shutter is a simple switch (not all cameras are), this simple circuit will operate the camera automatically, taking a picture every 5 seconds, from the time it is turned on. It only takes one IC, 3 resistors, and a capacitor to build it. The power is stolen from the shutter circuit of the camera. The 555 IC must be the CMOS type as it is being powered by the camera itself. The capacitor should be of a low leakage type, or the actual time will be longer than the calculated value. There is nothing critical about the construction. For minimum simplicity and weight, I used the dead bug construction method of flattening the IC and wiring the parts together without a circuit board. The...
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.....
