Television Camera Experiments

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 of visible light. On the other hand, most phototransistors provide peak response in the... .
Mini efficient coil launcher from disposable camera flash

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 is at the middle of the coil, there are some ways to do it but it isn`t important now. The .

Synchronous Camera Flash Trigger Using IGBT

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 advantages over the traditional SCR triggering mechanism: for instance, the width of the... .

All tubes are present and accounted for.It... .
1980 RCA TC-2811 First Generation CCD Surveillance Camera

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 shift registers. In operation, the imaging cy .
Programmable time-lapse camera controller

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 for the adaptor plate may be acquired from a manufacturer`s scrap bin. Be sure to ask for... .
5V Power Supply For On-Train Radio Camera

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 immediately. Consequently, the power source for the camera cannot be rechargeable batteries (since the .
Beam-break Detector For Camera Shutter or Flash Control

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 high output (+5V) as long as a modulated beam is detected. The IR detector (IC3) controls an .
Stereo Digital Camera Power-up Pulse Generator

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 with the ACC port ground. With experimentation, I find further that the synchronization... .
Lilliput auto video switching for reversing camera

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 Stunning Camera Circuit

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 project. The schematic seen above isn`t complete, however the general idea of the circuit is .
Interfacing to Sony Cameras

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 is added to the camera containing this circuitry. The earphone level is boosted wit .

Camera external shutter circuit 555 timer

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 a multivibrator can work. I purchased Engineer`sas a timer. Mini-Notebook, 555 Timer... .
Safe Sync to Adapt Digital Camera to Higher Voltage Flash

This circuit adds a datasheet-compliant trigger signal, reversed polarity protection, optional test button, and optional battery operation. U1 L601E3 or MAC97A8 triac. 400 V, 1 A. When U1 is enabled, the + and - wires of the flash are electrically connected, just as though the camera hot shoe had done so. A triac is a semiconductor switch,... .
Motorized Video Camera Mount

The camera rotator circuit uses a 2716 EPROM to store a table of logic values that control the motor driver (H-bridge) circuit. The EPROM data is shown in the schematic. By using the EPROM, a large number of discrete gates are eliminated. The logic table is designed to allow the motor to turn clockwise until the clockwise limit sensor is activated .
555 camera flash delay circuit

As the figure 17-1 showns, the camera flash delay circuit can be used to capture the high-speed scene, and you can get a very short exposure time. The light door is composed of the luminous diode and the 3DU type photosensitive tube. When the light is shadowed, the positive transition pulse adds to the VT2. The IC1(555) is triggered by the... .
