    Are datasheets important?

    Perhaps the oscillator works with the 100R resistor? but other data for the circuit might not live up to the datasheet values with this higher load! As an example the temperature range promised in the sheet might not be fulfilled! Also I suspect that stability will be affected with this extra...

    Angle Sensor

    Hi Tom, I would try a potentiometer of high quality with some gearing for this.

    building a generator

    Hi Ben, A car alternator can be used as a three-phase AC alternator if the diodes are removed. It is also possible to re-wind it to suit the voltage required. If you don

    Lighting, LED Flasher

    Hi Mike, This thermal flasher depends on a higher current to be drawn than the LED will draw to work properly. Try by paralleling the LED with a normal bulb and they both will flash. If you need the circuit to work with only the load from a LED you have to build an electronic circuit instead...

    "Tenna" PS-20 power supply

    This is a strait forward PSU, I am sure you can find all you need in the datasheet for the LM723. This datasheet covers all the basic circuits for the 723: http://eu.st.com/stonline/books/pdf/docs/4553.pdf

    Buck converter controlled by a microcontroller

    Why would you reinvent the wheel? There are a lot of chips out there with everything built in. All in one chip converters with high stability and no fuzz, why make something more expensive, complicated and less reliable?  :-\

    Basic wiring

    You must wire them in parallel (since both are 12V) and make sure the PSU can supply enough power to run both!

    How to know the ratio of a burnt transformer?

    1. Age makes the insulation weak and repeated heating and cool of makes things even worse. 2. The only way to determine the ratio (if you cannot find the data elsewhere) is to dismantle the  transformer and count the turns as you unwind the coils. 3. No I don

    optoisolator

    None of these can run a motor if not supported by some kind of power device i.e. triac, thyristor or relay. Please post the circuit so we can se what this is all about.

    optoisolator

    Unless the motor is extremely small the MOC 3041 (or MOC 3040) will be toast immediately!

    12 Volt to 220 Volt Inverter 500W

    Hi Jim, You are correct! That was a really dumb question!  ;D ;D The circuit you need for that purpose is much simpler to make. ;)

    Lowpass filter for subwoofer

    The appearance of capacitors differs between manufacturers and these might very well be ceramics. When repairing many different types of equipment one encounters various brands and learns to see the differences and similarities.

    hellp.........

    You will need more than a microcontroller to do this. To make a system like this secure it requires some sophisticated software and storage for all the samples from the people passing in and out of the factory/office building.
