The discussion revolves around a user attempting to create a pool heater using an old air conditioning unit, facing challenges with the circuit board design. The user needs to integrate a 240V AC supply and a 12V DC signal cable but is confused about having only one neutral for both AC and DC. Forum members express concern over safety and the user's lack of knowledge in handling electrical components. They advise seeking help from a qualified electrician or engineer instead of attempting the project independently. The thread concludes with a closure due to safety concerns.

Hi

I am currently making a pool heater and i have a comodated an old air con unit i have come to a point on the circuit board where i am stuck.

I am makeing a controler to send a signal to the outdoor heater but the out door heater has a 240v ac supplie and 1 live 12v DC signal cable. But there is only 1 nuteral for the ac and non for the DC.

I have an idea what board i need to make, I am just stumped with only 1 nuteral for AC and DC.

Help please
Thank you

Welcome to the PF.

We have a rule against dangerous discussions here, and with your lack of knowledge, it would not be a good idea for us to try to help you do this. Please find a local resource (EE, electrician, etc.) to help you with this project. Thread is closed.
 

Thread 'Does acceleration affect impact energy vs constant velocity?'

I do not have a good working knowledge of physics yet. I tried to piece this together but after researching this, I couldn’t figure out the correct laws of physics to combine to develop a formula to answer this question. Ex. 1 - A moving object impacts a static object at a constant velocity. Ex. 2 - A moving object impacts a static object at the same velocity but is accelerating at the moment of impact. Assuming the mass of the objects is the same and the velocity at the moment of impact...
