    BLDC Power Inverter Problem.. Need Help Urgently

    Welcome Sufiyan. Why are you posting out of date diagrams. Please update your diagram, this makes it easier for us as we don't have to remember it's now different. Adam

    "Lightpole" Project

    This can be done with a micro processor. I don't quite understand this part. "* The A light stays on. The COUNTER for A on the CONTROL UNIT is added to in actual seconds live" "* The B light stays on. The COUNTER for B on the CONTROL UNIT is added to in actual seconds live" And the counter, is...

    hi i need alittle help here

    What if you made a little chute for the quarter, like a cone in the bottom of the can and so the quarter always dropped through. You could then use a break beam of some kind to trigger the light. Adam

    PIC 12F675 PULSE COUNTING

    Yep that's a good one! Adam

    PLz help me with my project!

    Well if the voltage that appears on the emitter of the transistor is higher than the base by approx. 0.7 Volts then they will both be on. Adam

    PIC 12F675 PULSE COUNTING

    Can you put your checking and decrementing of count into your delay routine. You may need to adjust your timing for the extra stuff you are doing. Adam

    Osillascopes?

    Thank you Dorke for posting that link, very interesting. Adam

    Osillascopes?

    Hi Dorke. I find the higher sampling rate scopes much better for glitch detection. Used a Fluke scope-meter (500Ms/s) versus a Tek TDS210 (1Gs/s) and the difference is quite noticeable. Both had the same bandwidth. I put the difference down to the sampling rate? Adam

    Hello, Welcome! (Introduce yourself)

    Hi Johnny, welcome to E.P, hope you enjoy yourself here! Adam

    I'm fairly new to electronics, but have some idea,BUT how do these work?

    The tuned circuit, in this case would most likely be a parallel type with the capacitor connected across the inductor as the simplest form. The above formula is the frequency at which the tuned circuit is resonant and also has the highest impedance (parallel circuit only). This allows that...

    Osillascopes?

    If you are talking about DSOs then sampling rate is very important, just as bandwidth is. Bandwidth defines the amount of attenuation a signal will have at a given frequency, sampling rate is how accurately it is displayed on the screen. Adam

    Need to build an interface between an audiometer and a set of LED lights

    Ok just looking at this now in more detail and I have some questions. If you are using your own RHI (1 Volt in this case) do you need all the other resistors around the reference pins. Looking at the example in the data sheet, could you connect Ref adj (pin 8) to common and then the LED current...

    Need to build an interface between an audiometer and a set of LED lights

    Ok I have to go in a mo... as I am on lunch at work. Can you make Voltage measurements of all the nodes referenced to 0V common. So that's all the pins of the circuit including the power rail. Make a note of them and edit your drawing with these measurements. This really helps us see what's...

    Need to build an interface between an audiometer and a set of LED lights

    Do you have a multi-meter that you can use? We might need this later. Adam

    Need to build an interface between an audiometer and a set of LED lights

    To start with your PNP transistors look like they are connected differently to my drawing :) Adam

    PS4 lag...tried every fix I could find...PLEASE HELP!!

    Yes me too. Lets hope @Victoria Parish gets it fixed soon. I am off now, enjoy the rest of your day. Adam

    PS4 lag...tried every fix I could find...PLEASE HELP!!

    Yes agree, I don't think it's going to bring it down to 20 ms but it may help. I read that if you use Net-limiter and cut your bandwidth by half your ping will go through the roof. Adam

    PS4 lag...tried every fix I could find...PLEASE HELP!!

    When I upgraded from 20 Mbps to 50 Mbps my ping rate substantially changed, I would be surprised if it didn't up to a certain amount. Adam

    PS4 lag...tried every fix I could find...PLEASE HELP!!

    Depends if they limit the speed of the connection from different data packages. Ask them to reset your bandwidth, tell them it seems restricted.

    PS4 lag...tried every fix I could find...PLEASE HELP!!

    It makes a nice pinging sound. Only joking, it will tell me the round trip time to get a response from you through your IP.
