    Removing hard glue from Transformer coils?

    Think you will find it is epoxy based these days. Even the older motor varnish would be a one way process.

    Hegner Scroll Saw - Motor speed control issue

    Agree.....however, wouldn't be the first time someone has fiddled and stuffed a speed control in an old motor for whatever reason. That is what made me suspicious. Strange reply from manufacturer though " that this should be....." although previous owner also "thought it should be...

    small motor fishing line keeps snapping

    This is an electrical forum. What you describe is a mechanical issue so perhaps use a heavier guage fishing line or brickies stringline.

    How come the lamp won't light?

    So the red lamp is an LED or incandescent? If the latter, 2.5v @ 300ma approx, 8 ohm....8 ohm in series with 100 = 108 4.5v @ 108 ohm approx. 40ma which does not allow your (2.5 * 0.3 = 0.75w) bulb to light. To calculate 5mm or 3mm common LED current/ resistor values, common red led voltage is...

    How come the lamp won't light?

    What is the lamp? Voltage, wattage and what is the battery capacity(type) if you like.

    Most effective way to build simple counter

    8mm will be pushing it.......just a bare cell would be at least 10.5mm....but that depends .....never seen a ruler with " a little bit" as a unit of measure.

    Timer Circuit design needed... Help !!!

    Series ac motor requires reversal of armature in relation to both field coils. Problem is, some series motors do not take kindly to reversal due to the lead lag placement of the brushes. Result is usually a lot of sparking and eventually catastrophic burn up. Stopping would, if all above not...

    Designing Active Cell Balancer using STM-32

    Question is, just what type of cells are you trying to balance @ 1.5v? Apart from that, normal to load a cell to some degree on testing.

    Alternating L/R 4-way flashers

    Be aware most automotive is earth return. i.e. not as simple as one first thinks when weird things start to happen (feedback)

    Alternating L/R 4-way flashers

    Your description suggests it is only 2 way not 4 way....unless you mean left front , right front etc. If that is the case,rewire.

    Hegner Scroll Saw - Motor speed control issue

    What is the model number? There are fixed and variable speed models and your motor nameplate only says 1400 rpm. Not 400/1400 as in the variable speed type. M2039 fixed M2040 variable

    Help with a simple circuit

    You didn't mention time delay previously however........ The standard TTL 555 can operate from a supply voltage between 4.5 volts and 18 volts, with its output voltage approximately 2 volts lower than its supply voltage VCC. The 555 can source or sink a maximum output current of 200mA, (but it...
