DRIVE HOME AUTOMATION LIGHT LOW HYSTERESIS


SCHEMA DRIVE LIGHT:

This device serves to vary I'intensite one or more incandescent bulbs up to a load of 1000 watts maximum, by changing the amount of energy applied to the same bulb.



The arc of setting is very gradual with a particular bias circuit reduces almost to zero the unpleasant effect of hysteresis present in almost all electronic regulators of light. The device is equipped with a special filter that greatly reduced the spread RF interference


dimmer print system    



It is also recommended not to try to use this drive with neon bulbs.
It is advisable for those who use the device has the maximum power for prolonged periods, put a heat sink TRIACT1.

SWITCH SOUND: schema and realization of electronics assembly


ACOUSTIC SWITCH SCHEME:



It is a device sensitive to sounds and noises, Receipts in a microphone capsule and drafts act on a relay.



It can be set in two different operating modes:
1) The relay is energized whenever it receives a sound and de-energizes when the sound stops. 2) The relay is energized when the capsule receives a sound and remains excited when the sound stops. To energize, you have another sound. It thus functions as a switch in itself. It is a device sensitive to sounds and noises. It can be pre-rule in two different modes of operation With the DV selector in position 1, the relay is energized when the capsule M receives a sound and de-energizes when the sound stops DV With the deflector in position 2, the relay s 'excite the capsule M recoil when a sound and the relay remains excited when the sound stops. To energize requires a different sound. It thus functions as a real interrupteur.La sensitivity is governed by acting on the trimmer Tl. The microphone capsule is connected to the circuit by a small armored cable, it is placed at a distance (minimum 15 to 20 cm) in a way not not pick up the vibrations of the relay. The supply voltage must be 12 Volt DC stabilized. At rest the consommalion is approximately 1 mA with relay excited she is about 45 mA.















For the completion of the installation, you must follow the atlenlivement components planting scheme.

DETECTOR VIBRATIONS FOR CAMERA OBSCURE circuit schematic with explanation



It is an instrument of great precision and sensitivity, realized with very modern concepts. I / element
sensitive is is a photo resistance that is able to reveal smaller changes in light thanks to two transistors Tl and T2 connected in Darlington. Vindication of dimming is performed by a series of 1 6 LEDs.
DETECTOR VIBRATIONS FOR CAMERA OBSCURE circuit schematic with explanation




The connection between resistance and picture circuitry is printed with a cable effeclue blind. For the adjustment, you must proceed as follows:
1) Install the photo resistance in terms of the enlarger (sensitive part to haul)
2) Adjust the lens to a diaphragm of 5.6 or 8.
3) Adjust the enlarger for the maximum amplitude (maximum height). At present, adjust the trimmer Tl to the ignition point of the LED number 16. By lowering the enlarger, note the extinction of the aforementioned LED and I Ignition other depending on the distance of the light from the plane. Each LED corresponds to a number, just done the user, by precedent trials will build a table oil make it correspond to the numbers data, exposure times; and, whenever it will make prints it will have the exact indication of exposure time for any expansion.





DETECTOR VIBRATIONS FOR CAMERA OBSCURE circuit schematic with explanation


It is to be noted that for the operations of adjustment, and for normal use of the exposure meter, insert the film in the enlarger. Laboratory tests were performed realized by using an enlarger DURST B30 model with an objective NEOTAR 1: 3.5 / 50 and a lamp of 75 watts. Remember also that you should not perform tests with different values diaphragm, because, like any amateur photographer knows, for each additional diaphragm must double the time of exposure while for each diaphragm and less time is halved. Ie device must be powered with a stabilized 12 volts ; For mounting of components, follow the scheme practical implementation carefully.

The emit signal by the buzzer BZ is very unpleasant for I'ensemble insects and especially mosquitoes.



Its waveform that many harmonics. and therefore ultrasound SONL generes.La frequency of the signal is at the limits of human hearing threshold, the Q quartz can keep it constant. The system can be powered by AC or 230 volts with a single 9-volt battery. The maximum current consumption is 15 mA. The lighting of the LED ensures perfect functioning of the device. CAUTION! When batlerie is inserted, DO NOT connect the device to the mains voltage. WARNING! When the device is connected to the mains voltage 230 Volt AC, it must be very careful when handling. During assembly of the components, you must be very careful to insert the diodes in the right direction. A reversal in recent irreparably damage the assembly.












Given the signal strength (particularly with a supply of 230 Volts AC), the BZ buzzer can generate noticeable vibrations by a loud and unpleasant hiss. This disadvantage can be eliminated by insurant between the buzzer and the circuit will print a thick cardboard or foam rubber.
