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.... -
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.... -
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.... -
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,.... -
The photoflash circuit is showed as above. The seagulls SD - 150 type studio flash combines formative light and photography intense light source also accompanied by advanced synchronous remote control device of inside light modulation, which makes many.... -
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.... -
The camera flashlight circuit when K1 is put through, the self-motivation oscillator composing of BG1, C1, B1 and R1 is starting to work, after being boosted by B1 and rectified by D1, it is charging C2. DW2 makes BG4 conduct when it is 5.6v, the.... -
This circuit is composed of the light measurement circuit and the flash circuit, as the figure shows. It can be used in the POPTICS (one kind of popular integration camera), the Franka X-500 and the WIZEN-860S cameras. It is composed of the following.... -
The circuit is formed by light metering circuit and flash circuit,just as shown in picture.It is suitable for POPTICS (a popular integrated camera), Franka X-500, WIZEN-860S and so on.It consists of the following circuit:(1)VT1,VT2,light metering device RG.... -
Manufacturers are starting to turn to new high power to provide a photoflash function for these low-light conditions called white-light LEDs. These LEDs output....

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.....
