The M-88L70 is a full DTMF Receiver that integrates both bandsplit Filter and decoder functions into a single 18-pin DIP or SOIC package. Manufactured using CMOS process technology, the M-88L70 offers low power consumption (18 mW max), precise data handling.... -
A relatively simple attachment to my Canon SLR to create a motion activated camera using Arduino. A lot of this was based on and inspired by the intervalometer project at The Honey Jar. I made some changes to his circuit to use a 4N35 optocoupler instead of.... -
This is a fun and non-dangeros project for those people who like to throw projectiles magnetically. It simply works by placing a ferromagnetic projectile at one end of a coil and pulsing some power in it. The trick is to switch off power when the projectile.... -
This circuit was created for digital cameras. It`s known the digital cameras have considerable power consumption. For example my camera Minolta E223 requires approximately 800 mA. In practice a mains power supply or high capacity NiMH accumulators.... -
This acticle describes how to build a simple yet effective sound trigger for cameras or flashes. The circuit allows to experiment with high-speed photography.... -
This project aims to build an IR interval timer which can be used to capture images such as time lapse movies of sunrise or sunrise and the night sky. The.... -
A radio camera on a model railway should transmit constantly while the train is moving and continue transmitting for a few minutes after the train stops .. -
This circuit is presented as an alternative to the IR beam break detector featured in the June 2009 issue (Silicon Chip). In order to make it relatively i.... -
This circuit can be used for multiple cameras with one monitor. The circuit can be operated manually or automatically. When operated automatically the swi.... -
The CCD camera sensor is device that have very useful. This project has small size. But quality is a lot good. We can install with Television easily through the video in terminals. and connects to the video signal modulated to To send a broadcast RF signal.... -
JFET input. PN photodiodes such as the popular "bullet cell" put out an extremely low-level signal. Yet photodiodes offer advantages over phototransistors. For example, more rapid response to motion. Also, some photodiodes have a peak response in the range.... -
This is a fun and non-dangeros project for those people who like to throw projectiles magnetically. It simply works by placing a ferromagnetic projectile at one end of a coil and pulsing some power in it. The trick is to switch off power when the projectile.... -
This is a very easy instructable to build a digital switch for your camera in order to take photos with your microcontrollers. What you need: 1.... -
Typically a synchronous camera flash (e. g. slave flash) is triggered via an SCR. In this blog post, I will show you a circuit that can be used to trigger a secondary camera flash using an IGBT. Using an IGBT for camera flash triggering has several.... -
CRV-59AAE is 20" long by 9" wide by 10"high. It weighs a mere 33 pounds. It is at least 60 years old and in excellent condition. It represents some of the finest in miniaturized technology for its time. It uses an iconoscope tube as the imager. It contains.... -
RCA made some of the first commercially available CCD chips. A CCD (Charge Couple Device) is a silicon solid state imaging device that replaces the vidicon tubes of the past. CCD`s are made up a two dimensional array of photo detectors coupled to an array of.... -
With a few basic hand tools and a digital camera, this programmable camera controller project is for you. By using components already available at home, costs may be kept to a minimum. A servomotor may be reused from a radio-controlled model and aluminium.... -
A radio camera on a model railway should transmit constantly while the train is moving and continue transmitting for a few minutes after the train stops. But if the train starts up again after a relatively long halt, imagery should be transmitted.... -
This circuit is presented as an alternative to the IR beam break detector featured in the June 2009 issue (Silicon Chip). In order to make it relatively insensitive to ambient light, it uses a standard IR receiver IC such as the Jaycar ZD-1942. This has a.... -
Powering up my twin digital Sony DSC-V1 cameras at exactly the same time frequently synchronizes the cameras to a remarkable degree, within milliseconds. The cameras are powered up by twinned Sony wired remotes by shorting the ACC port LANC signal conductor.... -

I have been reading a lot of posts about the Lilliput not being able to `auto switch` even though it is in the secret menu, so I decided to make a.... -
The schematic for this project is not terribly complex, however it is very important that you understand the circuit board and how it operates because of the high voltages that are generated. Below is a `rough draft` schematic of the camera used for this.... -
The Clearcom type intercom bus runs at a significantly lower level than the Sony bus, the signal to the camera operator`s headset must be boosted and the signal from the camera operator`s microphone must be attenuated. To do this a very small circuit board.... -
Just 4 integrated circuits and an handful of passive components: the circuit of the Witnesscam is simple. The AVR ATmega32 does an excellent job here. Add the JPG camera module, a PIR sensor and a spare SD-card and you`re done!.. -
Having wired the camera with external shutter leads I now needed a way to trip them. They needed to be tripped (i. e. connected together via a relay) at a regular interval, perhaps 2 seconds, starting at launch. I had read that a 555 timer chip configured as....

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..... -
The best human ear can capture sounds from 20Hz to 20KHz. These limits are known to be the broadest that can exist. Normally the normal limits range from 100Hz to about 13KHz and depend on the age and health of the individual. We for our measurements and to....
