Most homes today have at least a few infrared remote controls, whether they be for the television, the video recorder, the stereo, etc. Despite that fact, who among us has not cursed the light that remained lit after we just sat down in a comfortable chair to watch a good film? This project proposes to solve that problem thanks to its original approach. In fact, it is for a common on/off switch for infrared remote controls, but what differentiates it from the commercial products is the fact that it is capable of working with any remote control. Therefore, the first one you find allows you to turn off the light and enjoy your movie in the best possible conditions. The infrared receiver part of our project is entrusted to an integrated receiver (Sony SBX 1620-52) which has the advantage of costing less than the components required to make the same function. After being inverted by T1, the pulses delivered by this receiver trigger IC2a, which is nothing other than a D flip-flop configured...

There are 2 kinds of solar automatic tracking controllers. One is Schmitt trigger light control composed of a light sensor and a Schmitt trigger or monostable trigger. Solar Automatic Tracking Controller Circuit Diagram: The second one is usingtwo light sensors and two comparators to form two light-control motors and controlforeward and reversing. As throughout the year, the strength of the sun in the morning and at noon changes in ambient light, and the range is enormous, the above two controllersare difficult to make large solar energy receiver track in the sun-weather season. The control circuit described here also includes two voltage comparators. Butthe input side of the light sensors is composed of two photosensitive resistors connected in series.

Here is a light-operated, remote-controlled solidstate switch to operate a lamp. During darkness, the resistance of LDR shoots up to meg-ohm range. Thus, the triac does not get gate drive and hence it does not conduct. Circuit diagram: Light-Operated Light Switch Circuit Diagram When LDR is illuminated by means of a torch-light beam, the resistance of LDR suddenly decreases (below 10-kilo-ohm). This causes the triac to conduct and switch  ‘on’ the lamp. Light received from the lamp (not from the torch) keeps LDR’s resistance low. So, the lamp re-mains continuously ‘on’. Once the lamp is‘on’, it can be switched  ‘off’ again by in-terrupting the light falling on LDR, by either waving hand in front of it or by interrupting power supply to the circuit for a moment. RFC emplo-yed here can be made by winding about 15 turns of 18 SWG wire over an insulated ferrite rod. Author : Pradeep G.  - Copyright :electronicsforu

Here is the simple virtual ground circuit based on discrete components. This simple design comes from miniaturization guru Sijosae. Is to make a buffer from generic discrete components. The transistors can be most any complementary pair of small-signal transistors. Suitable alternatives are the PN2222A and PN2907A. The diodes are generic small-signal types. An acceptable alternative is the 1N914. This circuit has better performance than a simple resistive divider virtual ground, and the parts cost is lower than for any other circuit mentioned here. It is, however, the least accurate of the buffered virtual ground circuits.

This circuit was developed to power an AVR microcontroller from a 12 V lead-acid battery. The regulator itself draws only 14 µA. Of course, there are dedicated ICs, for example from Linear Technology or Maxim, which can be used, but these can be very hard to get hold of and are frequently only available in SMD packages these days. These difficulties are simply and quickly avoided using this discrete circuit. Circuit diagram : The series regulator component is the widely-available type BS170 FET. When power is applied it is driven on via R1. When the output voltage reaches 5.1 V, T2 starts to conduct and limits any further rise in the output voltage by pulling down the voltage on the gate of T1. The output voltage can be calculated as follows: UOUT = (ULED + UBE) × (R4 + R2) / R4 where we can set ULED at 1.6 V and UBE at 0.5 V. The temperature coefficients of ULED and UBE can also be incorporated into the formula. The circuit is so simple that of course someone has thought of it before...

Introduce Lenovo Debuts 5-Inch Vibe X Smartphone . Lenovo unveiled its new Vibe X, a fairly clear-cut smartphone, at IFA Berlin on Thursday. The 5-inch apparatus arrives with a 1,080p IPS display, a quad-core, 1.5GHz processor, a 13-megapixel camera (coupled with an oddly powerful 5-megapixel one on the front), 2GB of recollection and 16GB of storage. The specs are admirable, but they aren't the best out there. although, add in the premium polycarbonate body — which is just 6.9 millimeters thick and weighs about a quarter of a pound — and Vibe X becomes a solid lightweight competitor in the crowded 5-inch Android arena. On the programs edge, just like most of its new brethren, it sprints Android 4.2. The Vibe X will never reach European or the U.S. coastlines, we've been notified. Price and release designated day are not yet available.

This Simple Cmos Motorcycle Alarm Circuit Diagram features an intermittent siren output and automatic reset. It can be operated manually using a key-switch or a hidden switch; but it can also be wired to set itself automatically when you turn-off the ignition. By adding external relays you can immobilize the bike - flash the lights etc. Cmos Motorcycle Alarm Schematic Diagram     Notes Any number of normally-open switches may be used. Fit "tilt" switches that close when the steering is moved or when the bike is lifted off its side-stand or pushed forward off its centre-stand. Use micro-switches to protect removable panels and the lids of panniers etc. Once activated - the rate at which the siren switches on and off is controlled by R9 & C5. For example - increasing the value of C5 will slow it down - while reducing the value of R9 will make it faster. While at least one switch remains closed the siren will sound. About thirty seconds after all of the switches have been ...

Hey, what should we do today? How about making a fuzz pedal? Cool, I knew you were up for it. As you may be aware, I’ve recently been helping my friend Adam with a few guitar projects and he was keen to get started on pedal making (specifically a fuzz pedal). I suggested the Bazz Fuss as an easy starter project. It’s only 5 components (and a pot) and it sounds good too. It's designed primarily for a bass guitar, but it sounds great with a normal guitar too. Here it is (note that I laid mine out slightly differently, and I eventually swapped the 10k resistor for a 100k one): [from http://diyyoguitare.hautetfort.com/archive/2010/07/13/bazz-fuss.html] And here's my very professional layout: Since I hadn’t already made a Bazz Fuss myself, I decided it might be fun to do so. Apart from having one for myself, it would be handy to have one to refer to if Adam ran into any issues while he made his. I decided to challenge myself a bit and see if I could fit it into a Hammond 1590A enclo...
