    Can i discharge Li-lon Battery Pack

    Hi, Most laptops I have encountered will work fine without its battery pack present. If you need your computer and have access to mains power you should be able to run it if you remove the battery. However, I’m not sure if it’s possible to discharge the battery outside the computer and make it...

    NiMH Battery Pack Charger

    That circuit will not supply a constant current!

    Water Tank Water Level Indicator

    Oh, I assumed there was a walk-a-round inspection path for the tank. Is it completely buryed or is its top above ground level? A mechanical device would be the safe way to do it.

    antispeed gun radar

    Yes, that would be very interesting. And a similar device for laser guns is even more useful!  ;)

    Voltage cutout for analogue meter.

    Yes, that will probably work well. Are you running the winch with contactors (relays) or is it run through a controller (adjustable rpm)?

    antispeed gun radar

    Hi arsal, Welcome to our forum. I don’t know where you live or which standards are used for the speed traps in your country. There are four or five bands used as far as I know and you must know your “enemy” to be able to get a fair warning. One should be aware of the fact that sometimes the...

    Water Tank Water Level Indicator

    Why not a transparent tube on the outside from top to bottom so you can se the exact level at any time?

    power trouble

    Depending on the length of the surges from the motors the PC can be protected from shut downs simply by adding a diode and a capacitor to pick up the slack.

    system operation

    Hi Munky, Have you got the values for the parts too, it might help. It looks like a “vox” or similar but I’m not sure!

    Voltage cutout for analogue meter.

    Many shunts have a 5 times the measuring current load limit, however only for a few minutes!

    power trouble

    If the load peaks is too high for the batterys internal resistance the voltage will drop and the computer might shut down. You should consider larger capacity batterys.

    Strange behaviour of 78xx reg.

    Hi Tony, When I build something I like to be able to touch any part of it with my fingers without getting burns. Any excessive heat is a waste of energy and a reduction of lifetime for the circuit. However this “technique” is not applicable for every kind of circuit and then you has to...
