    Make a Microwave oven on a small-scale

    This is a change of pace ante, and for a change I do have some answers. How I came about to understand how microwave ovens work. It was many years ago and I was working as a labourer for a small electrical company for about three months, probably the most interesting and exciting job I have...

    Strange Voltages

    Hi xenobius, why don't you just use an adjustable voltage regulator :).

    Make a Microwave oven on a small-scale

    Ante, I was thinking that a small magnetron would be a little less risky and easier to manage, then a larger one from a microwave oven. If I was to use a microwave oven/magnetron, it would be very difficult to use for experimenting with, because it can only be turned on at full power. I can't...

    Schematics Variable current 12v 60A to 0A

    Ante, the collector of Q2 should be going to the positive side, I really should not of made that mistake :-[. R4 was in the original circuit, I thought the same thing why is it there, maybe it had a function in the original circuit, I wasn't sure so I left it :-\. Yes SW1= ignition switch. Yes...

    Schematics Variable current 12v 60A to 0A

    Ante, I think you are right 8). I'm still trying to find my feet, on the best way to go about developing and putting together these circuits :P. Well this is the result of starting over from scratch. The three relays are activated together by the RPM sensor switch via W3. RLY3 is there to...

    Make a Microwave oven on a small-scale

    Ante, I am trying to reason with the possibility of making my own magnetron :o, can you see any problems with a magnetron maintaining its same function, if I was to replicate it exactly to a small-scale, I'm just considering the possibility 8). What I really need to know at this stage is what...

    Make a Microwave oven on a small-scale

    By the looks of things I need a magnetron that is a third of the size, or maybe smaller. Has anyone invented a shrinking Ray yet :o. Does anyone know of a device, that contains a small magnetron. Or maybe another way it could be done. ante, have ya got any old radar equipment in the...

    Make a Microwave oven on a small-scale

    Thanks Suraj, their sure is a lot of information on microwaves their ;). Steven, I found the circuit you posted, but I can't understand how it works,( lack of knowledge ;D) is it for producing microwave energy.

    Make a Microwave oven on a small-scale

    I would like to understand how a microwave oven works. I would like to experiment with microwave's, to be used in conjunction with electrolysis for producing hydrogen. From what I understand on how microwave ovens work, by vibrating molecules to create heat. I think it may be possible to...

    12v Relay on When Car Running

    It looks good to me. But keep in mind I am only a learner. The mechanical side of a vehicle is more my expertise

    Schematics Variable current 12v 60A to 0A

    Ante, I think I know how I have to go about this now. I'll say that again I think ;D. I'm going to start from scratch, instead of trying to modify these schematics and making a big mess. I have the first schematics that I modified in front of me, as well as the one I just posted, I am...

    12v Relay on When Car Running

    This may help. A post from Ante, helping me with my project. Mud is the word my friend, on some points I can see what you are aiming for. If you want an indication that the engine has started just use the charge indicator light. This takes no sophisticated electronics to achieve. When the...

    inverter

    He did mention that they were popular in China 8). Maybe that's why they don't think they need a good marketing strategy ::).

    inverter

    You would think that the first thing to mention would be its power output. Anyone looking for a inverter, usually wants to POWER something from it. ;D

    Schematics Variable current 12v 60A to 0A

    Ante, I just had an idea on solving the problems with the regulator, in keeping the 12 volt battery isolated, from the varying voltage. Does this looked like it will work in principle. I have basically isolated the stator from the field coil. It's a bit muddy at this stage as usual ;D.

    fax machine with enhancement

    I don't know why anyone would bother with a fax machine, when you have a computer. I send and receive faxes with my fax modem which is very old. It is a little slow but does the job well :).

    Schematics Variable current 12v 60A to 0A

    Ante, I have a question about the six diodes, for the three-phase. If my maximum current was to be 200A, what would the maximum amperage need to be for each diode. Would it be about 33A four each diode, plus a little headroom.

    Schematics Variable current 12v 60A to 0A

    Ante, at our local tips we have recycling plants, and dump rats as they are known as. These are people who own the scavenging rights, and sell anything and everything that they find, that may have some value. I'm a little reluctant to pay good money for something, and find after I've taken it...

    PCB software

    I am glad to hear that I am not the only one, that finds Eagle PCB hard to use :P. Maybe there's a special class somewhere that you can attend, sometimes it seems like there should be :o ;D ;D.
