    Connect Switch Receiver

    As I understood the reply from the OP, the new unit is a general purpose remote, in no way associated with the door.

    Any idea for this switch?

    Link a standard push button momentry contact switch to a 555 monostable.

    How do I run a dc motor slowly?

    . No it will not..........If you read the suggestion they are "gear motors".......miniature units. Many different voltage ratings and gear ratios available.

    Cash deposit for battery

    Usually because the cost of transport of " dangerous goods" exceeds the scrap value.

    Working of a JK Flip-Flop. Help needed with the circuit.

    Try talkingelectronics web site. Many beginner circuits and animations there for various things.

    How do I run a dc motor slowly?

    There are small dc permanent magnet gear motors on Ebay for around Aus$8.00. Maybe 20mm long and 14 wide x 10 high. 6v one should run ok on 3v. For xtra one can even get an encoder already fitted. Lovely stuff.... I saw a query for size earlier but no answer was forthcoming.

    Photoresistor Issue In Water Filter

    . I hope you mean you measure the ldr out of circuit? Zero does not sound right, 1k0 does.

    Solenoid Help

    Cannot see the wattage on the coil but I wouldn't mind betting it exceeds the current handling ability of those little smoke alarm batteries.

    Trouble finding 120V DC - 10A breaker.. alternatives..

    Both are used, input and output DC and AC. DC isolators adjacent to the panels are also a requirement in many instances, depending on your location.

    Connect Switch Receiver

    I'd be surprised if there was not an after-market keyfob available on Ebay or similar. What is the type/model/brand of the door?

    Stupidly Simple Question

    Seems to me that if there is a mains input and a low voltage dc input that you have lost 2 leads. Have you gone back to where you bought the item and asked them? If a retail outlet I think they should be able to point you in the right direction.

    Controller board fails to stay switched on

    I pointed to the link you supplied as it states there in section 2 that the battery has to be charged for a full 8 hours before use. Now I could be wrong but that sort of infers that the system runs off the battery and the solar provides a re-charge to some extent. I took it that the solar did...

    Trouble finding 120V DC - 10A breaker.. alternatives..

    Moeller Schneider make a range of circuit breakers to suit solar installs. Most we have anything to do with are higher voltage and 6Ka rated but that would make no difference to your application. Most authorities require use of double pole breakers for the incoming dc off the panel.

    Using CCFLs from broken laptop screens - how well matched do tubes and power supplies need to be?

    They run on high voltage and care should be taken using these outside of any casing otherwise you may just make more of a pretty light than you expect. A much safer alternative is the LED version. One can buy these from Ebay ( 2 strings and a driver) for around Aus$15.00.

    Controller board fails to stay switched on

    Did you follow all the instructions in the link you provided? Did you check the battery as it sounds like it might be faulty or not charging or both. With the crystal and two caps I assume the chip is a microcontroller so if one or the other above faults exist, perhaps it's program is...

    Turn Signal and Side Marker in the one bulb?

    CMA, Had a closer look at your post but I cannot see what drives the park/turn in the original. Not clear exactly what you are trying to do as the original seems to cover it. Apart from that, the mosfet link is a good idea. What they are doing there is simply using a P channel which is...

    Turn Signal and Side Marker in the one bulb?

    Quite simply , it won't work. Circuit shown is a basic steering diode arrangement. As shown it will work with one input or the other without disrupting any other circuitry BUT when both are active the light will just follow the continuous "on" signal. What you will have to do is use the blinker...
