Xenon Circuits

In this strobe-light, two circuits are needed; one circuit charges a capacitor placing 320 V de between the cathode and anode of the flashtube. The other circuit provides bursts of approximately 4000 V to trigger the flashtube into conduction. The.... -
This strobe gives a visual indication of a sensor input. The input signal causes Ul, a light dependent resistor, to chaijge CI.. -
The circuit is activated by an LED/photoresistor isolator (Ul), which is a combination of a light-dependent resistor (LDR) and an LED in a single package. That device was chosen because of its high isolation (2000 V) characteristic, which is necessary.... -
This strobe light operates from standard 120-Vac power. Rl limits the amount of current applied to the voltage doubler stage, which is comprised of CI, C2, C3, Dl, D2, C4, C5, and C6. Capacitors CI, C2, and C3 are connected in parallel and form a.... -
Initially the neon and xenon lamps are not conducting and act like a very high (almost infinite) resistance. Capacitors Cl and C4 in conjunction with DI and D2 form a voltage doubler circuit, which can charge C2 up to about 300 Vdc after several ac cycles..... -

This Adjustable Strobe Light is the bigger brother of the plain old strobe light. This one uses a much more powerful "horse shoe" Xenon tube which produces more light. You can also control the flash rate up to about 20Hz. Do not look directly at the flash.... -
This DC-DC converter ("inverter") needs nothing but unmodified Radio Shack parts. You don`t need to build or wind any coils or transformers. This is a cheap-and-dirty experimenter`s circuit. I tested this and it worked for me, but I disclaim all warranties!.... -
Figure 1 shows a complete circuit for an emergency lamp that operates from a 12V automotive battery. The xenon flash tube requires a 250V-dc anode voltage and a 4-kV trigger pulse. To generate the 250V dc, IC1, a switching regulator controller, and T1, a....

Cell phones and PDAs are approaching the limit for small form factors, but their feature sets are growing with new functions such as built-in cameras and even video cameras. The initial in-phone cameras were basic, low resolution devices with little in the....

Since the circuit operates at greater than mains potential and is not isolated by a transformer, it is extremely dangerous. The DC operating potential is about 340V, and there is more than enough stored charge to kill you many times over (although in my.... -
Flash lamp is made ??with experimental parts removed from a disposable camera flash circuit.Xenon try to use what I think is easily affordable experiment. AC100V to a voltage doubler rectifier, DC voltage of about 270V is derived. This voltage is R2, C3 is.... -
The way that this circuit works is as follows. The AC line voltage is rectified by D1 and D2 which connects to a voltage doubler circuit made up of the two 22uf capacitors. The Flash Freq. Pot and the 10uf capacitor charge up which triggers the Diac and.... -
If you have no idea what is a "strobo", "strobe", "stroboscopy" or whatever way it is called, it is simply a flashing light. It is usually used on police cars, 'disco' places and many interesting applications, including scientific ones. This project is.... -
This circuit typically uses a voltage around 300 volts for the main high voltage supply and needs a low voltage supply of typically 6 to 15 volts. 555 pin connections not shown above: 1 goes to ground / negative of both low and high voltage supplies. 4,8....

This is one of my stroboscope designs. Usually many stoboscope circuit work directly from mains voltage, but this circuit uses 12V DC intead od mains AC. This is very good idea if you don't want to mess with direct mains voltage connected circuit or you want.... -
This page contains some information on circuits which can be used for triggering stroboscopes from external circuits. The circuit here are designed to be integrate to strboscope circuits so that they can triggered using external trigger pulse. The standard.... -
A stroboscope is an instrument which is used to view the object which is moving rapidly with a periodic motion as if they are at rest. The strobe light flashes at a frequency that synchronizes with the resolution of a wheel or moving object which seems to be.... -

This circuit is xenon lamp flash detector. It has a very low standby current requirement yet has very high sensitivity toward the light flashes from a xenon lamp. When connected to a flip/flop it can serve as an on on/off controller... -
The circuit was taken from one of the old elektor electronics magazine and it is indeed a very cute little circuit which may be used for creating high intensity lighting effects during festivals, parties and fun gatherings. Diodes D1 and D2 along with the.... -
