    timer

    Sorry, this has got a bit out of hand. I was hoping for a simple circuit and all I got was complicated questions and answers. Went into a parts store yesterday and bought myself a cheapo kit. well, it wasn't all that cheapo! in fact was darn expensive for what it contained but it will set me off...

    timer

    OK, so you have a spoon in your hand and you put it down on the unit and take your hand away. Sorry if that sounds patronising but it was the only way of explaining it. :D Deigh

    timer

    I am involved in a project where a small and inexpensive timer is required. Can anyone help me with a circuit? Requirements are that it be battery powered and that anything placed on it would cause a light (LED) to switch on and stay on for a certain time. This time should be adjustable from...

    phones

    A few months ago I had to purchase a new phone to use the new frequencies allocated by the government. I purchased a Samsung and had a lot of trouble getting used to it. It costs twice as much to run as my previous unit but that is a crafty move by the ISP people to make more money. Have now...

    can I run a laptop on a 12VDC 'car' battery?

    I've just purchased a Samsung computer which is 12v. I have ordered a cigarette lighter plug-in device on the internet which should run it. Unfortunately it is coming from Australia and hasn't arrived yet. I have tried several inverters but they do not work with the existing battery setup in...

    computer/amp interface

    Sorry about not answering, didn't realise it was required to answer everyone, Answered four out of five My amp has no line in. I liked your idea of adjusting the volume in the computer and planned to have a look at in today. The downfall was that one would have to remember to reset it All...

    computer/amp interface

    Just getting to grips with updating my guitar playing equip. Now using windows 8 and find that when I plug the output from the earphone socket to the amplifier the output is too great and distortion results. Obviously I need an interface between them to correct the imbalance. Anybody got...

    lockable knobs

    t once again the simplest approach would be perspex over the panel. Thanks for those leads. The second one would be ideal till I looked at the price! $16 US would be about $20 NZ and I would want eight of them. WOW! :eek: Think I will temporarily drop back to your sheet of perspex idea and...

    lockable knobs

    Don't think so, the shafts were normal and the knob mechanism locked on to them in the same way that the normal knobs do. Might end up having to make them myself but my workshop facilities are pretty poor at the moment.

    lockable knobs

    No, nothing like that at all! Thanks for try though. Knobs were silver and just looked like any others except that to use them you had to pull them out a click, then they turned the shaft. Release them and they clicked back into place and would not turn. This solved all the problems of...

    lockable knobs

    Being a clumsy guitarist (fumblefingers is my nickname!) I get a bit annoyed having to set up my amplifier anew every time I move it into and out of the car. I'd like some knobs that actually lock in place and have to be pulled out slightly before readjusting a setting. I know these things do...

    Amp

    See the letter from Duke37 yesterday, I followed the instructions and the only reading I got was the input so it looks as though the unit has died.
