    Looking for a mentor

    This is a forum, I doubt you will get anyone with the time to do this but I might be wrong. If you have specific questions then why not post them on here and let us all help you its much more fun. Much better than just one Mentor, we have lots of members that have experience in lots of different...

    Motion captor (with ball)

    You could also try a simple tilt / vibration switch. If the old unit just triggers the toy then this might be an option. But if the old sensor has a timer in it which controls the toy then it won't work. Have a look here for examples...

    Laser dalek!!

    Hi Yes I would think its no problem. Just waiting for our resident Darlek expert Kris to come on line. :) Adam

    Lead-Acid temperature compensation in charging

    Temp compensation is important if you are charging it at high or low temp. The other thing that makes a difference is how much current you are using to charge the battery as this inreases the batery temp, also if its wet or gell type makes a difference. Aceptance charge for gell type and wet...

    IR volume control for Onkyo AV receiver?

    You would need to know the IR protocal to do this. If you can find this then yes it could be done. You could be a bit naughty and order one and then get one of those universal remotes to learn the codes. Then send the exspensive one back for a refund. :) Adam

    Why was this equation required to be in metres before resolving?

    Hey dont worry. They thought Einstein was simple when he was at school. He was just bored :) Adam

    Cannot figure out the connector name/model

    Going to be a tricky one me old mucker. Unless someone on here has used that type before. Adam

    Cannot figure out the connector name/model

    Ummm needle in haystack springs to mind. Are there any markings on the connectors? Adam

    design 1A current limiter for my 300V dc supply

    I think the FETS ok the way it is, being a N type the input will be max 12V higher than the source clamped by the zener. You need to change the value of R2. Reduce the value to 0.5R and try that. Adam

    Non-changing current with C-EMF

    Can you just clarify a few things please. You show the power source as a battery, are you planning on switch this on and off if so at what frequency. You show something that looks like a magnet, is this producing the changing magnetic field or is this just a horse shoe magnet of some kind...

    Measuring Sine Wave Using ADC

    I agree he was not very clear Kris, but he mentioned measuring a 1 KHz sine wave I guess he wants to measure the frequency also. Adam

    Non-changing current with C-EMF

    Can we have a bit more detail please. A circuit diagram would be good, and as Gryd3 said what's it for. Thanks Adam

    Measuring Sine Wave Using ADC

    You could try converting to a square wave and then measure the period using the timers of the micro. Then take the reciprocal of this and you have your frequency. Otherwise I think you will need to sample a lot to measure a sine wave. Just an idea Adam

    [woo] Does anyone know of this breakthrough technology ?

    So it's still basically bollocks then, as we originally thought. Adam

    Why was this equation required to be in metres before resolving?

    Hi Chopnhack The SI unit for length is the metre which is probably why they used metres. They have complicated things by writing 1mm instead of 1*10^-3 m. So it quite easy for someone to enter this as just 1 and not 1*10^-3. I always use the *10^x button on my calculator so enter the figures as...
