    Replacing touchscreen on exercise bike console

    I would imagine it to be an oem device. Replacement with the same unit may or may not be complex for such as yourself. Difficult to say as it depends on the unit and your level of adaptability to new situations. Thing is, it may be other interface devices at fault or failing.

    Powering system using battery

    I would not put too much credence in a POC such as that. Balance charging is not the issue, the way it charges and the cut off levels, is. The charger I use comes in at around $80.00 odd but there are cheaper, just as there are more expensive. One could try the cheap versions but no guarantees...

    That's what I said, yes.

    Powering system using battery

    One can get ready made bms boards relatively cheap so one could make the battery(3s would suffice) from single cells. Bms boards available in a variety of current ratings, 3A I believe the smallest. Arduino can take 12v at the raw terminal without any other converter. Lipo cells require...

    Rain gauge resetter

    The unit i have here is rechargeable AA and a small solar panel adjacent to the sensors. Even so, the data there is not stored for more than a couple of minutes where it then gets sent out to the main unit for long haul storage.

    Rain gauge resetter

    Many of these have a download to pc usb facility...... As far as the rain collection bucket is concerned, it's normally just a simple reed switch and magnet which pulses once each transition. This is collected in the main receiver along with any other weather data available on the different...

    I'd like to know how put a digital sound bite on a component

    Can be done via an SD card, an adaptor and an Arduino along with suitable power supplies and amplifiers etc. for playback and some general uC know-how.. In this instance the SD card being your wav storage device.

    Connecting the OLED-048O064A-LPP3N00000 to a PCB

    Most would simply use the already made interface board.

    Question About Resistors

    There is available a standard pin for pin drop in flasher unit that operates as a timer as opposed to current draw for flash rate. You may need to search for one which suits your model of vehicle.

    Powering LEDs Question

    Even could go 2 legs in parallel, 6 leds in series and a 100R resistor in each of the two legs. Original circuit would exceed the current rating (200mA) of the 555 (216mA)

    Shaded pole motor.

    If you intend going miniature, you could give a thought to brushless motors from any of the r/c aircraft, drones etc. Tons of torque and speed controlled via cheap esc controller and an equally cheap servo tester. Can be battery powered or via old pc power supply or plug pack...

    LI-ION 18v Battery Pack

    I have a car that keeps stopping, so can you tell me what's wrong..?? Show some details otherwise it is just an educated guess but we don't live that long to list the possibilities.

    LI-ION 18v Battery Pack

    I'd have to see this to believe it. Then again I have a neighbout who mows the lawn at night with a 4 foot fluro and extension lead cable tied to the handle bars. If you already have the wheel barrow as a carry device for your power source, perhaps wack a generator in there for almost unlimited...

    Fan regulator feedback generator

    Show the specs and a circuit diagram of the complete system. That way someone may be able to get some idea as to your application. Other than that, crystal ball batteries are down this end.

    Fan regulator feedback generator

    Why would it need feedback..? Assuming you mean ceiling fan here...if not, then be more specific. The ceiling fan motor runs at the supply frequency minus slip on high speed. On lower speeds it's just a stab in the dark speed anyhow.

    LI-ION 18v Battery Pack

    If these are nicads, where did the 18650 query come in...?? Either way, at 1.3Ah it is not a large capacity by any means so one might deduce the current is not all that much. To answer you question though, calculating the motor current from the Ah capacity is not possible.

    LI-ION 18v Battery Pack

    Your use is in a battery circular saw so check what current the saw draws under load. It should have it on the label or a spec sheet if it is a reputable brand. Reason being, the cells have a maximum discharge rate. This can be a certain amount over say a few minutes or just burst of a few...

    LI-ION 18v Battery Pack

    Note to watch the discharge ratings when you buy the cells in that application.

    LI-ION 18v Battery Pack

    RS Components in the UK would be one . There you can check the cell specs at least. I have used Hobby King at times and they seem ok but times do change.
