    Electronic flourescent tube starter

    Well, that kind of shows your age, as that is basically codswallop. I once saw an American electrical handbook from the 1940's saying "mains test for dead" could be done using the back of one's hand which goes into the same catagory. Aside from that it appears some of the circuits described...

    Electronic flourescent tube starter

    Dick Smith electronics used to have a kit for fluro electronic starters. I made one perhaps 30 years ago and it worked fine but at a cost. At the time I think around $16.00 AND one had to de-gut a good starter AND it was a really tight squeeze to get everything inside. There were no changes to...

    electrical disturbance on my Raspberry-Pico because of to the electrical motor controler

    No doubt but there still remains the question surrounding where the 5V feeds a 1k resistor top right and bottom right, and then also feeds 3 x circuits (hall ?) bottom left. Point being you would need to common ground somewhere for this to work at all. Therefore optos no point. I'd say redraw...

    electrical disturbance on my Raspberry-Pico because of to the electrical motor controler

    I see there has been some attempt at complete isolation of the grounds by using Gnd and GndRef (I assume separate) However you come unstuck when you make your 5v common ground. No idea how you managed to get that part to work at all unless you made it all common ground. Then you loose the whole...

    I need help picking my bms for my battery pack any help is appreciated

    Depends on your load current requirements. They are available for 3A ($2-$3 each) right up to the 25A shown above. Search for 3s bms on any of the online suppliers.

    Power supply for CB

    You'll need to supply the make/model of your power supply or possibly even better, a link to the supply spec sheet.

    Servo Stop and Reverse

    Well, it was you who poo pooed the same suggestion first up in #3 so don't shoot the messenger. In fact if you bothered to look you'd see the suggested replacement fitted your "mode first turned on" requirement. I'd say best you make up your mind about what you really want.

    Getting voltages from transformer

    Yup, ok but secondaries weren't overloaded , rating was 5A and load was 2 x 2A plus 100ma for the 5v. Does no harm to have one secondary open circuit.

    ADT Safewatch Pro2000 of 25years died

    Lightning travels thousands of kilometres through the atmosphere, so it very rarely ever stops at one component when it gets to electronic circuitry. Time to go shopping for a new device methinks. :cool:

    Getting voltages from transformer

    Once you get it rectified and cleaned up, you could use dc dc converters to give you whatever you like. Depends largely on the transformer capacity (VA) and the load current you require, both of which you do not mention.

    Why Raise Capacitance in Smoothing Caps?

    Then there are inductors for current ripple......

    Servo Stop and Reverse

    Your best approach with anything is to Google what you want as, many times what you think might be your unique idea, would have been thought of before. Such is an example of a quick Google search. https://www.instructables.com/Two-Mode-Servo-Tester/

    Servo Stop and Reverse

    Servos will not withstand anything above 6v normally. There are some that do but most will not. There is an ebay servo tester that runs servos either manually via a pot or automatically through their range back and forth for a couple of dollars.
