    Pool water level stabelizer

    There is no big problem using electrodes to control a relay. Just like an automatic bailout pump for a daycruiser a timer closes the relay 5 minutes or so after continuous contact between the electrodes, this will cure the problem. No rattling relays! But if using AC the electrodes can be partly...

    Pool water level stabelizer

    My experience with sensors is: use stainless steel rods and AC voltage for sensing. Just my two cents. ;)

    need robot magazine

    I believe whatever subject in robotics you are looking for its in some of these books. Are there any particular things you know exists in the books you are looking for and nowhere else?

    Best of 30 LM3886 Application

    Hi AG, When extracting RAR files: I always use the right mouse button to pickup and drop the compressed file on an empty folder and choose extract here! This is less fuzz and no nagging! ;D

    need robot magazine

    Hi smuralisankar, There are many robotics books here: http://ebook.blogfa.com/cat-1.aspx I am not sure about the once you asked for but I believe you will find most of what you need in here! Are you familiar with the SERVO magazine? It’s all about robotic stuff!

    Then you have a faulty stepper motor or some other kind of motor! Stepper motors will even whiteout shorting the wires have clearly noticeable steps, and when shorting the leads it will be very sluggish! Unless of curse the magnets or the windings are gone, then it will spin easy!

    Hi AG, There are many ways you can turn the stepper. If it has a belt wheel it’s enough to turn it between your thumb and index finger. A small crank will work fine too, windmill, gears or rack and pinion with a spring! There are endless possibilities! Even a small stepper generates a fair...

    car battery tester

    Hi MP, Rabid says: “looking at the plans for the “"Simple but reliable car battery tester"”! I just wanted to make sure he didn’t think this circuit works like one!

    Is bluetooth safe?

    There are some values issued by the authority who tells us when it’s dangerous but the accumulated influence is not possible to know.  No one can answer this for another 10 to 15 years when we have had time to study the effects and diagnosed the users! :o Take Care! ;)

    Extract the Code from the Programed and encrypted MCU

    Unless it’s illegal there is no reason to “extract” the code from a chip! ;)

    shake light

    Hi, If you need a battery less torch it’s much better to use an old stepper motor and a few diodes or rectifiers and some bright LEDs. It’s possible to charge some Ni-Cads with the stepper or if you need some backup and don’t want rechargeable cells you can use a Gold-cap or two! Almost any old...

    car battery tester

    It is wrong to call this project a “Simple but reliable car battery tester” this project is not a battery tester! It is a voltage measuring device which reveals nothing about the batterys condition just its voltage!

    Hi Feng, Can you post prize information including shipping for Europe please? I don’t think anyone here is interested in buying a 20 or 40 feet container full of these so prize info for just a few would be nice! ;)
