    Can anyone give me the name of this?

    Have a look at JST and Molex connectors to start with. Adam

    Can anyone give me the name of this?

    The bottom picture is the only one I can make out as being a connector. Can you see any logos or writing on the connector. adam

    Questions on LT3080

    The V control pin is separate so you can reduce the power dissipated by the internal transistor by running it from a voltage very close to the output voltage. As Hop mentioned I believe the package is used even with an NC pin for it's thermal properties. Adam

    Hi James Looks like some sort of connector. The pictures are not very clear and the item is too far away for me to see properly. Adam

    controlling hc-sr04 more than one at the same time

    Have you tried to put a delay between the two measurments, say 1 second. Adam

    controlling hc-sr04 more than one at the same time

    What sensors are you using? Do you have a data sheet? Thanks Adam

    controlling hc-sr04 more than one at the same time

    Please explain what your code is suppose to do. And what in particular is not working? Adam

    Solder mask or thru-hole mask in PADS Layout 9.5

    Hi John I have been using PADS for 15 years so you have come to the right place. What you do is setup your TOP layer to be a split mixed plane and add your net you want to use for the plane, go to set up layers for this. You then select the whole board outline and right mouse click and choose...

    RL low pass filter, Voltage across inductor at 100hz

    I make it 154 mV peak across the inductor not 58 mV. Adam

    RL low pass filter, Voltage across inductor at 100hz

    Oooops sorry I thought it said resistor... I'll shut up now :)

    RL low pass filter, Voltage across inductor at 100hz

    But if you measure across the resistor what do you get? This is where it gets interesting... If you try it with another voltage say 10 Volts, what do you get? And if you measure across the inductor what do you get? This should confuse you initially. Well it might do :) Adam

    Considering a design change

    I don't mind either, I think I prefer Fluid V2 Adam

    Considering a design change

    Looks fine to me Beaker. Adam

    I am to design a switched mode psu without IC components.Help please

    This is the sort of thing I am thinking of. This is how your block diagram should look. This is an example only and your blocks may differ and some blocks you may not implement on your design. Adam

    I am to design a switched mode psu without IC components.Help please

    Ok that's a great start. I personally would start a block diagram of the circuit showing power connections and output / inputs coming from and going to the relevant blocks. You can then take one block at a time and look at a circuit for that. Then you build the next block and so on. It's...

    7 segment display driver and counter

    Yes you are correct! Adam

    7 segment display driver and counter

    Just a lucky guess :). Glad you have it working now. Adam

    I am to design a switched mode psu without IC components.Help please

    Ok I am going to bed now, I'll have a think about it and try and help tomorrow. But there is a great bunch of far more knowledgeable guys on here than me that will most likely beat me to it. Adam

    7 segment display driver and counter

    First thing I would try is adding some supply de-coupling and support. Add as close to the IC as possible a 100 nF across each ICs power supply pins. Also add a 2.2 uF- 10 uF Tant or electrolytic capacitor ideally across each ICs power pins (observe correct polarity) but if you can't do that...

    7 segment display driver and counter

    Hello and welcome to E.P. Can we see your circuit diagram if you have one? Adam
