    Need to test some fuses

    As duke37 says, you need to get some more info from your customer on what the fuse is supplying. Have they checked the actual current flowing through the fuse? They may have selected the wrong size fuse. Does the fuse blow on power up or after some time? What type of fuse are they, eg glass...

    #5000

    Well done. Mind if I ask how many keyboards you have worn out in the process?:D Hope all you guys with huge numbers of posts still have time to do your own projects.

    Remote whose buttons need to be held down

    Also use the cotton bud to clean the battery connections. Check tension between the batteries and connectors. Are you using 1.2v rechargeable batteries instead of 1.5v dry cells? Are you using good quality batteries? I assume you have tried new batteries. Try gently pressing components on the...

    wi-fi

    Probably need to boost the free library wi-fi signal at its source. They must have a reasonable signal already if you can pick it up 300m away. Not sure that the library would be too pleased if they realised that they were providing free wi-fi to the whole neighbourhood though.:)

    20A CB not activating

    Sorry Marrion, but I am totally confused by your posts. Please clarify exactly what you have and what you are trying to do.

    12V Battery on a 230V/50Hz Pump

    Our goldfish pond has a low voltage 12vac pump. It came with a 230vac to 12vac transformer. Brand is Pondmaster. Easy to install. Being low voltage it doesn't need the cable to be installed to meet safety regulations. Transformer is in the garage and twin core cable runs around fences to pond...

    Microwave Door Switch

    Can you measure the current through the switch? Can you buy the correct switch from Frigidaire?

    Microwave Door Switch

    This is a European standard. The first number is the resistive load. The number in brackets is the inductive load. A is Amps. 16(4)A 250V = 16 Amps resistive load, 4 Amps inductive load, 250v.

    What Potentiometer should I get to control the speed of a computer fan?

    Are you using the fan in a computer, or are you using it for another application?

    measuring 3 phase circuits correctly

    Would using an oscilloscope give a better idea of what is happening to the CNC router power supply?

    AC Compressor blowing fuse

    I just keep two 1000v diodes in stock; 1N4007 for low current inductive sources, eg relays, hydraulic solenoids etc, 1N5408 for higher current inductive sources, eg aircond clutches, starter slave solenoids, etc. I always fit the diode as close to the source as possible.

    Any idea what these are?

    Look like Deutsch DT socket terminals.

    Power Supply Questions

    What current do you require at 48V? What current do you require at 24V? Why not use the Arduino 5V regulator?

    Protection diode melted and burnt

    Thanks Steve. I also see that they use 100E instead of the usual 100R for R1.

    Protection diode melted and burnt

    C4 has a symbol that I am not familiar with. What type of capacitor does it indicate? 1N4007's are the only diode I keep, so fitting one would be my first move.

    Automotive Switch Panel

    Haven't seen any DIY touch screen switch panels in vehicles yet. I have seen some panels made up using these switches that look very good. http://www.amazon.com/Silver-Stainless-Illuminated-Latching-Pushbutton/dp/B0062P5GZG Might be a good project for someone to build with a touch screen and...
