    RCD Fault - I'm dumbstruck

    Hi Guys, I'm still haven't got round to testing this double socket. I can't remember how to carry out the tests, can someone briefly describe how to test it to jog my memory? I have a standard multimeter.

    Corded Drill - How does it work?

    "The motor used in corded drills is often a universal motor due to its high power." "The universal motor is a type of electric motor that can operate on both AC and DC power" Thanks guys! Now I know what I'm looking for. :]

    Corded Drill - How does it work?

    Hi Mursal, Thanks man, I admire your google/keyword skills. Haven't looked at one with brushes and a commutator, I studied motors a few years back, so I know those are DC right?. The assembly diagrams on here are really useful.

    Corded Drill - How does it work?

    Hi Guys. I have a report to write about a corded drill. This includes inside the drill, its components and how it functions. I can't seem to find the specific names of all the components within the drill. Could anyone please point me in the right direction? The corded drill is AC 230...

    RCD Fault - I'm dumbstruck

    Yeah I can understand why that would cause a fault, and I have had to go through a tight bend.. although its all thermoset plastic. No obvious signs of damage, I'll disconnect the spur and see what tests say.

    RCD Fault - I'm dumbstruck

    Hi Guys, I have recently installed a new double socket, so I can put both my tumble dryer and chest freezer in a convenient space :) It's flush with the fuse board/consumer unit, and a direct spur from the ring main. However, when I use the double socket, I get an RCD fault. Note: that the...

    12V - 6V circuit to drive motor

    Thanks Steve, appreciate your help. I'll post a circuit diagram before I make a prototype on a board, Ash,

    12V - 6V circuit to drive motor

    I'm comfortable with PWM and those conventional good practices you mentioned. So hopefully all goes smoothly. One simple question, what is the 10k resistor between the gate and source for?

    12V - 6V circuit to drive motor

    Okay, so how about a 555 timer set-up in PWM with a trim-pot to preset the duty cycle to 50%. Then a high rated transistor or fet to switch the motor on the collector? AH is capacity - I really should of known that.

    12V - 6V circuit to drive motor

    Hi guys, I'm planning to repair my nephews electric-powered quad bike. I measured the '6V 5AH' battery voltage after a full charge cycle with a reading of just 3.6V, so i'm going to replace the battery. Having three spare 12V batteries I decided it would be best to create a small circuit to...

    Ceramic Capacitors Voltage Breakdown

    Thanks Steve, much appreciated.

    Ceramic Capacitors Voltage Breakdown

    Hi Guys, Is there a specific breakdown voltage for a 0.1uF (104) ceramic cap? I'm assuming ceramic caps can handle 12v comfortably, but what is the common breakdown voltages of these capacitors?

    Help with transformer. Large surge currents

    The important thing is I've learnt alot during this thread, perhaps this will be avoided next time. If I can't find another, ill have to buy one. Thanks everyone for your posts, :) Ashley

    Identifying 3 unkown components

    Just as Duke said, the last components are Film Polypropylene capacitors (plastic caps), I found an example of one here http://www.tedss.com/2222-464-73011. The axial plastic capacitors like this one is obviously less common than the radial leaded type. Thanks everyone, Ash

    Help with transformer. Large surge currents

    Some important pointers there Duke, I'll need remember them for identifying more transformers in the future :). The transformer is used around audio and video then, which explains the copper band. Nice googling skills Steve, :) Is there still hope in re-using this transformer? I can see...

    How to break a faulty wireless keyboard and mouse.

    Hi, I'm not sure which country you live in but in the UK, if a company refuses to repair or replace you item, you can report it to your local Trading Standards Department because they're breaching your 'statutory rights'. If you phone the retailer and tell them your going to do this, it might...

    Help with transformer. Large surge currents

    Sorry guys was quite busy yesterday and couldn't reply. Yeah my 2A power supply is DC. Sadly I don't have a bench power supply, just my cheap 2A DC supply. My multimeter doesn't have an inductance function :(, I'm going to buy either a multimeter or bench supply in a few weeks because I need...

    Help with transformer. Large surge currents

    I tested the other two transformers at 240V with a 100W bulb in series, both tests lit the bulb brightly aswell. I have tried putting 5V a set of windings in order to perform atest with my multimeter, but it overheats my 2A variable voltage supply just at 2V so had to switch it off. Is it...

    Identifying 3 unkown components

    Okay so we're sure we have ferrites and most likely axial electrolytic capacitors. I need to check the accuracy of my multimeter on brand new capacitors before testing the capacitors as it's getting old. I'm going to write out the markings on the last set of components because its much easier...

    Help with transformer. Large surge currents

    Hi Bob, I think so, I'm assuming the primary side is the one with just two input pins on this specific transformer. But how can you identify them if they have multiple pins on both sides? By the size of the windings?
