    Schematics Variable current 12v 60A to 0A

    Ante, it has been very difficult to try to find, a IC that is reasonably priced and has the features we need. I have been very reluctant to choose one of the more expensive ICs, because of my inexperience, and I have to design the PCB. I haven't used surface mount chips before, and the mistakes...

    My computer is slowing down!!

    Buy a bigger hammer ;D. Well that's what I feel like doing, to my machine sometimes. If you have Windows XP and have recently installed new software, try restoring your machine to an earlier point, or even if you haven't installed new software.

    Schematics Variable current 12v 60A to 0A

    How about this IC. I can get it, and it is very reasonably priced. And if it is suitable, I'm keen to get the soldiering iron fired up, and happy to stop looking at datasheets. Businessman ante, can you start a business by ordering in four components ;D. Maybe the oil companies have heard of...

    transformer windings

    I have run into problems in using transformers, and trying to work out how they work, and trying to understand why it didn't work the way I expected. Now I understand better :D. Thanks for sharing Kevin.

    Schematics Variable current 12v 60A to 0A

    Ante, I am pleased to say that I can get all of Farnell components ;D ;D ;D. Actually to say pleased is an understatement. They sent me their catalogue, and their catalogue on CD. their catalogue is in three parts well over 2000 pages combined. There CD is set up for business use, and...

    PC oscilloscope useful or not

    I was wondering if anyone was using a PC oscilloscope. And if they really have any practical use in electronics . What would be the best set up to use, to be the most useful.

    Schematics Variable current 12v 60A to 0A

    Ante,is this the kind of IC we're looking for :-\. I feel like I have looked at a million datasheets. They're sure is a lot of them. hopefully I'm learning something by going through them all. I sure do, get a shock at the price of some of them :o.

    Schematics Variable current 12v 60A to 0A

    The time it takes doesn't matter, a successful outcome does. I'm beginning to wonder if I have taken on this project too soon. Considering my very limited knowledge in electronics :-\. Ante, do you think the electronics side of this project, is the sort of thing a beginner should be taking on...

    Wanted: Old Serial Mice

    I have one, and could probably get more, but it's a long way to send them to you from Australia. There are plenty of opportunity shops here were I live. These are organisations like guide dogs and Red Cross, that set up shops to sell donated clothing white goods etc. It's amazing what you can...

    \Need these parts. please look in

    Hi stuee, I have the same problem in trying to source components in Australia. I will soon be constructing a project, that the components are going to be hard to find. If you find a good supplier of components in Australia, please let me know. I will let you know if I come up with anything.

    Schematics Variable current 12v 60A to 0A

    Ante, the catalyst is going to take some time to discover, I think there is going to be a lot of experimenting with my prototype to discover it. The stirling engine, would be ideal to use with my hydrogen power engine, to drive the alternator. I think space is going to start to become a real...

    ultrasonic mosquitoes repeller

    I have a circuit for a mosquito repellor, in a book for getting started into Electronics. I haven't tried it so I don't know if it works. I will scan it and post it.

    Schematics Variable current 12v 60A to 0A

    Well I have a lot to say ;D. yes I think my post are getting progressively bigger. Maybe if I had broken them down into multiple post, I could have been upgraded from Newbie >:(.

    Schematics Variable current 12v 60A to 0A

    Ante, I should explain the steps or stages,that I would like to go through to discover and improve on, all of the unknowns in this system. Budget is a factor until I at least yield positive results, and still the budget is very tight. I would first need a good PWM that I can rely on for my...

    Beer has been legal to brew for as long as I can remember. Distilling spirits is only illegal if you get caught ;D. You can buy a still from your local homebrew shop legally, but the pot must be less than five leaders and you don't refer to it as a still for spirits, it's for extracting...
