    555 astable

    will reqire a slightly different circuit with diodes added to even get close if my memory serves me correctly.

    555 astable

    Very seldom , if ever, do I have a problem with any of the "imported parts". More likely the pots as mentioned earlier. If you do not like/cannot do the maths, there are numerous online interactive calculators which will give you a variety of values, depending on which end you need to start...

    Battery Car Starter - Voltage is not fixed

    If the starter is a direct drive it will be substantially more than that........ try around 250A.

    Sony KV-8AD11 ac/dc TV power on issues.

    I cannot see what you can see, therefore relying on your photos which are not clear in the area of interest. Therefore, from your current description can only gather the bridge rectifier IS the "black plastic connector" Assuming you have continuity to the mains power, (connector CN603 I...

    What do you suppose the amps are for this solar charger?

    Maybe 50 mA in full sunlight and facing due North if in the Southern hemisphere if you are lucky.

    Connect two relays in parallel from one power source to activate a pump

    Just use the time delay relay on it's own. The circuit is not quite right as it shows normally open push buttons which would need to be kept pressed to operate. If these are in fact toggle switches, then the on-off would be included with the delay relay on it's own. Assuming delay is to switch...

    Sony KV-8AD11 ac/dc TV power on issues.

    This is like getting blood out of a stone............. again I'll ask.....where does the wiring which plugs in to D601 go...?? Can you show a photo of that. I'm guessing it it a remote bridge rectifier unit. Without that, nothing works.

    What do you suppose the amps are for this solar charger?

    Probably around 2W. Wasting your time trying to charge a battery with that.

    Sony KV-8AD11 ac/dc TV power on issues.

    It's not to test the connector, rather, to see and check what is hooked to the other end of it. Would help to supply a few photos of what you can see there, we are flying blind. Have a feeling this is going nowhere and you need somone with some electronics experience. Not only that but you...

    Sony KV-8AD11 ac/dc TV power on issues.

    Connector D601 appears to be a 4 pin connector and the markings on it suggest a remote bridge rectifier. ( 2 AC markings and 2 DC, positive and negative) Has this been checked. Difficult for you to do anything unless you have even a basic understanding and a multimeter.

    Analogue correlation circuit to measure water flow in a pipe?

    Water Resources Qld used to use anubars placed in the flow to measure up and downstream pressure difference, then the meter would calculate flow. These were later replaced by ( minute in comparison) external ultrasonic transducer unit, not much bigger than a cigarette packet. The latter was over...

    Arduino Resets -- Why?

    Better to use Bertus idea and use a 12v relay module.

    Balance Potentiometer Bypass

    Just copy the connections...I don't see the problem.

    Balance Potentiometer Bypass

    No idea what this is supposed to mean. If referring to connection and the pots are measured and set to centre as it should be, there is no difference.

    Balance Potentiometer Bypass

    I suggested you just replace the existing balance pot dual gang with 2 x 50K miniature pots (centred) and hang them inside somewhere. I think you will find the reference to 22k resistor would be to use 4 of them. Two each join together in series, 3 wires from each pot section go to the end ...

    Balance Potentiometer Bypass

    not a good idea to go shorting out any input outputs, bound to create problems there

    Balance Potentiometer Bypass

    Perhaps replace with a couple of 50k trim pots set to centre. They are small and could be left floating with a small amount of insulation tape wrapped around each separately.

    Portable Battery Charging Pod for E-Bike Trailer

    Yes but he still has to drag his own weight around AND it is a limited period of output, i.e. cannot be sustained at your theoretical figures. It still comes down to any energy will have to be in excess of the above AND as already proven, maximum output is 1/7hp which is a tad over 100w...
