    In circuit transistor tester

    Look at that one The design shown will test PNP and NPN transistors, diodes and SCRs both "in-situ" (equipment of course de-energised) and also by direct connection to a stand-alone component. It is a simple GO/NOGO test which can identify diode and transistor action and will indicate diode...

    Inside a TO-3 Transistor case

    I have heard about this but I never thought It was true. Do the Solar Cells have the same working structure ???

    Making PCBs with magazine's paper

    Ante don`t worry the electrolyte consists of Sulphuric Acid and distiled water the standard is 60% Sulphuric Acid and 40% Water of course different manufacturers add other chemicals to lengthen the life of the battery.I should be more worried when I start the electrolysis process because there...

    Need part for Samsung TV

    Why don`t you replace it with another one model part the bridge is not a critical part like an IC, transistor,diode or else

    Making PCBs with magazine's paper

    No I mean electrolysis Here it is how it works You get an old car battery you take the electrolyte then you mix 1 liter of the electrolyte with 300ml of distiled water (30%).Then you put the liquid in a tub you put the plus electrode to the copper which has to be eaten away and you use for a...

    Making PCBs with magazine's paper

    Haha I`ve been using this method for making PCB`s for year and more.There are a little secrets for making these PCB`s. First for me I`ve tried so many types of paper but I think that the best one is Ink Tec`s Premium photo paper. The most important process is the ironing most of people say...

    project ideas

    Try building a robotized hand It`s easyer than u think U need just stepper motors and drivers for them.

    First Project

    Actually my first project was a Time Delay Relay Why don`t you try this? The first delay relay I made had only four transistors after that I tryed the 555 timer monostable,astable mode after that CMOS circuits, TTL and so on and so on.Just you`ve got to be patient.Don`t worry if you burn a chip...
