    555 Circuit

    http://www.talkingelectronics.com/te_interactive_index.html Scroll down the left hand side to 50 ...555 circuits. Click on that....... Scroll down main page to complete list under the heading "contents". Click on delay... As an added note, does your LED strip require a driver or is it built in..??

    Dual DC motor wiring help

    Dynamic braking is normally a good idea on freerunning motors however, with the gear ratios involved here and the load of the passenger, it will not even be noticeable As far as nothing will catch fire, when dealing with LiPo batteries, especially those with the sort of capacity you show in the...

    Samsung Monitor repair

    It could be backlight problem. With the monitor turned on, if you look at an angle to the screen with daylight reflection, can you see any really dim image on the screen..?? Failing that, you will need a multimeter and with it set on DC voltage, run through the measurements on the terminal...

    Detecting horizontal position

    How much space is this..? A quick sketch would help.

    Dual DC motor wiring help

    If the supply is a tad over double and the motors are the same, where does 4 times the speed originate..?

    250v 150mA Slow Blow fuse replacement

    More likely a fusible 18R metal film resistor. Mostly these are used as inrush current limiters in smps power supplies. It is sometimes (not always) an advantage to use a 150w floodlamp in series with the suspect power supply input for testing purposes. At turn on if the fault still exists...

    Powering a linear actuator with a battery

    Just be aware the 2.3Ah is a 20 hour discharge rating. 1C discharging to 9.6v pd is only 1.3Ah.

    Safety capacitor for a Singer Sewing Machine

    They are simply rf suppressors. No idea where the term you use (safety) comes from.

    12volt solar power cables

    Freezer has a motor and motors draw up to 6 times full load at startup. If the capacity to drive this is not present, the motor simply will create a voltage drop that will hold in the start winding until the motor burns out. Exception to this is inverter style drives which freezers don't have. I...

    Current sensing using Arduino

    Still has the analog problem requiring averaging. Whereas the INA219 module is digital I2c.

    Help Testing if LED TV Power Board is Functional

    Cannot follow your description here but normally a 5v supply is a "startup" voltage and the unit is waiting for some input from the operator to start the main power supply section. It may be you have unplugged part of this requirement for successful testing.

    Motor timer.

    Arduino microcontroller is probably the simplest and cheapest way to go but you will need to learn how to code the sketch. These devices were made for such things. You could use hardware timers and time delay modules etc but I doubt you would follow the requirements. First you need to get the...

    DC Motor Low RPM under load

    Motor undoubtedly driven by the relay. It may well have cooked contacts and even cooked coil. I would disconnect the motor wires at the motor and connect directly to a 12v car battery for a short test.( couple of seconds) That would eliminate problems within the motor. Motors like this do not...

    Momentary Switch Bypass

    Information given should therefore be no problem to follow then at that rate. Still waiting for you to provide useful details on the "smart plug". What you have to recognise is, we have no idea what you have in front of you until you provide the details we require. Jump up and down as much as...

    dc electric bike questions

    Appears just where these mystery reading came from are lost into oblivion forever. I've no doubt some resemblance will pop up some time in the future though.:):)
