    need help

    Maybe he might like the one I used to work on. Powered an Air Traffic Control tower for 3 hours. Ok. Maybe a little large.

    9v + (2xAAA) = ????

    I think he means solenoid or more precise, a relay.

    9v + (2xAAA) = ????

    You could use a 3.3V regulator on the kit that runs off the 2 AAs. This way you could run them both from the 9V battery. If 3.3V is a bit much then you could also put a Schotky diode in series with the 3.3V supply.

    Scope calibration service???

    In this case I would say there is definately a problem. I don't think this is a calibration problem either. I would say there is actually something wrong with it internally. There must be somewhere in your area that can repair it. I am in Australia so I can't recommend anyone.

    dipole antenna formula

    I assume when you say formula you want to know what dimensions you need to use. If this is the case then you should consider the centre frquency that you want. To make things easy we will use 100Mhz which is close enough to the centre frequency. Now that we have 100Mhz as the frequency one...

    Scope calibration service???

    I think you may have missunderstood my question. A CRO probe has an earth/GND lead on it. Sometimes when the probe doesn't have its GND lead connected to GND then there may be some spurious pick up at the tip. There could be a small GND point on the front of the CRO. Try connecting the GND lead...

    Scope calibration service???

    Silly question. But have you put your earth lead to a decent earth?

    dipole antenna formula

    You are correct. They are very rare and also don't work all that well. But they are useful in confined spaces.

    dipole antenna formula

    What do you mean by formula? Do you want a half  wave or quater wave dipole?

    Need help

    Can you post a schematic of what you have. It is hard to understand what you are having problems with.

    Hey all. New member ere. Little help please??

    I don't think so as the glowing of the wire has nothing to do with current flow. It is purely resdidual heat from the previous firing. As the fuel is compressed the flash point of the fuel lowers and bang. To start a glow plug engine you need to apply a voltage to the plug. This is removed once...

    Hey all. New member ere. Little help please??

    As I suggested try getting a colder plug. Most model stores that stock the engines should have a full range of plugs.

    Is this funny?

    OUCH

    Temperature Probe

    Well to start with 200F is not all that hot. Not even boiling yet. Most semiconductor manufacturers make temperature sensor chips. For example an LM45 is a 3 pin device that we use here quite a bit. It is rated for -20C to 100C (212F). This is quite small but it is an SOT-23 style package which...

    Hey all. New member ere. Little help please??

    The only way I know of other than reducing compression is to buy a colder plug. Maybe try a weaker fuel.

    Amplitude Modulation

    Premece. Take your little oscillator, glue some sharp razor blades to it and place it where the sun don't shine.

    Amplitude Modulation

    I know this might seem a bit of a cop out but being a college project it should be you designing the circuit. And you are correct, it is a simple task. How about you start with a design and post it here and we will give it a go at improving it or fixing it.

    Hey all. New member ere. Little help please??

    It sounds a lot like a glow plug engine. Similar top those used in model planes and cars. I am not sure why you would want to limit the glowing of this as it is what ignites the fuel. Stop or reduce the glow and it may fail to work.

    Voltage level shifting

    The current sensor I am using is an LEM LTS15. A little drift won't be to much of a problem so super stable designs aren't required. This is more of a confidence circuit.
