    Hi,

    I am a freqenct visitor of this site and really like the detailed articles on basic topics. Good thing about these articles is that they deal with advanced topic yet keep it easy to follow. I am a person with basic electronics background but detailed computer knowledge.
    I would love to see an article on setting up of dome cameras and controlling them wireless via computer or just the basic of how to get started about those.

    Thanks
    Vivek

    A correction Please. The topic I suggested on December 2,2011 at 8.31 am, is not for charging the Mobile phone while on Rail journey, but to supply power to Mobile Phone direct, bypassing the regular battery available in the Mobile Phone. By mistake I mentioned it for charging the mobile phone. With the above means One can have an uninterrupted talk (if he wishes) as the power supply is supported by a Power bank of 6V 4ah rechargeable battery. Thanks. VG KRISHNA.

  4. V GOPALA KRISHNA

    We often find ourselves wanting a provision to charge our mobiles phones while on Rail journey. The need is more felt when the journey is long. Provison for mobile charging is not provided by Railways (except in higher class) in the coach for each individual/one scoket each. I wish that there should be a stand alone arrangement to be carried by individuals for charging the mobile phone while on journey. For this purpose a circuit is to be developed by innovators for charging mobiles phones while on journey. The power should be drawn from a battery like 6V 4Ah, a rechargeable battery (with treasure of power),to get the required supply of voltage and current in milli amps to charge a typical mobile phone. Also there should be a provision of a socket to the mobile phone which bypasses the regular battery in the phone in the above suggested case of charging. I think people will not hesitate to carry this item in a small box, eventhough it may weigh 1/2 kgs. I hope in future the Manufactureres of Mobile phones should think of giving such facility to mobile phones, so that the phone will not starve for power while on journey. V G KRISHNA.

    Hi Judie 500watts amp with 12 volt 2amp power supply (24watts power) supply?!!
    Hi Shoaibee depends on the required time duration of the light, you have to rate the battery (terminal voltage, AH rating etc)and charging circuit.

  9. Judie Franz Marquez

    Single chip 500-watt amplifier with no external components other than the power supply, speakers, heat sink, volume control, switch, input jacks and LED power signal with a standard equalizer. This is one design that would not take over 15minutes to complete. Needs only a very small PCB. Operated at 12voltsDC @ 2 amperes power supply. “Small but terrible”

    AUTOMATIC MOTOR CONTROL USING LOGIC GATES
    OR
    MICROCONTROLLER
    -: Using this Condition :-

    (1)When head tank is empty and ground tank is full, motor(relay) starts running. [If ground tank empty show warning.]
    (2)When ground tank get empty or head tank get full stop the motor.
    (3)For sensing water level use AC current.(Which prevent electrolysis of water.) graphite[Lead of Pencil] will work well for prevent corrosion.But in DC it starts electrolysis of water.

    If possible it show 3 or 4 desired water Level.

    In countries like India, Pakistan & Bangladesh people use ceiling fans in summer. When it is time of change of weather from summer to winter the problem occurs that at early hours of night a certain fan speed is required but in early morning hours say 2.00 am to on ward it makes more cooling effect.

    Why not modify existing fan speed dimmers with some thermister control so that it automatically regulates speed according to room temperature.

    You can have robotics as a field. Though it has mechanical and computer science involved i feel its nothing without electronics. Moreover the world is going automatic with robots all over so it must be the most wanted topic for all.

    Please published full description of USB Audio Kit,”Which can play MP3 audio file from pen drive and out Audio with out computer. which can attach any type of Audio Amplifier .

    Microphones for PC sound cards need a relatively high impedence of 2500 to 10Kohms. Many microphones are cheaply made and its hard to tell meet needed specs. or if they will work with devices, i.e. tape recorders, PC sound card, etc. How about a circuit to measure the microphone’s impedence. I don’t think that a simple resistance check by a meter will work.

    Reference article in Linux Pro Magazine #93 Aug. 2008,Article name “Learning Curve” page 64, under the paragraph Sound and Vision, next to Figure 1. Cite that impedence values above.

    I agree with the first comment regarding programming in embedded C.

    My idea: Article on Interfacing pitfalls. Connecting different technologies. Like ttl/cmos. And the very basic. How to connect and not to connect stuff to a uC.

    Rock on 🙂

    A safety mechanism to protect electric door bells

    I would like you discuss a solution to the following situation.

    A safety mechanism to protect electric door bells. I had to replace couple of electric doorbells due to prolong pressing of the doorbell switch at my gate by visitors. Some keep on pressing without waiting for a response.

    I would appreciate you discuss this idea and come up with a simple solution to cut of the supply for the doorbell for a specified time, when the switch is pressed once. It has to be operated with mains supply of 230v or 110v.

    Almost every houshold has a Quartz clock which in many cases does not keep time very accurately

  232. Maurice Gooneratne

    Please publish an article on how to adjust a quartz clock make it run slow or fast) Thank you

  233. Hari Kiran

    I wish you can design a circuit that is used in Quad copters to control flight & stabilization that is controlled using a transmitter and receiver kit including some sensors like
    1. Ultra-violet sensor
    2. Gyro sensor
    3. 3- axis accelerometer
    I think it is a little difficult but can be done, If you take it as a challenge you can really work on it

  235. suman

    My idea is
    “RF based automatic speed limiter for vehicles”..
    This project is very useful to reduce road accidents if it is implemented.

    Tutorial series on programming microcontrollers (avr vs pic) and hardware features for different chip models.

  245. rajan singh bhadoria

    1.you have to give the details of inductor coils like how to make.
    2.you can give the whole projects or a pack of projects in one click download.

  246. mubarak

    make a digital watt meter, which can measure the usage of electricity.By this we will be able to know our electricity consumption from time to time .Thus our electricity bills can be reduced and moreover energy can be conserved.

  247. rakesh

    Sir,
    I need no prize, but if you consider this two topics:-
    1> usb to parallel port(bi directional) converter :—
    I think, this project will further help developing more projects.

    2> usb to optical output converter/usb-optical fibre interface (bidirectional data connection)

    3> Digital security lock
