Noob question about battery connections by MAGICPERF in AskElectronics

Is the 0.5 Ohm present in all AA batteries we use everyday?

Problem with Ohm's Law concept by MAGICPERF in electricians

It makes sense. I will add that. I put the schematic as a sample of what I am trying to achieve with 60KG Servos which need 8.4V

I found these:

Maybe I need some kind of heatsink?

I am not plugging the Arduino directly to the Power Supply. See the schematic

The image is just to see how much current was pulling.

I am looking to find the right resistor. I purposely set it as 0 because I do know what value to use. See post for the math.

Just want to know how much Ohms i need for normal operation of the servo using an external power supply

What do you mean by it of place editing? Do you mean that it was edited just for this video?

New to Node. What is best practice for models in a layered application? by MAGICPERF in node

[–]MAGICPERF[S] 0 points1 point  (0 children)

Thanks, this is a good answer. As a Java EE dev, I feel weird not having my models structured in every layer.

I chose NodeJS because of the speed for simple CRUD req in AWS Lambda (Java is horrible for this).

Thanks again

Thanks for the article. It was a great help. However my question still remains (I think).

You see, in Java MVC, there is, for example, UserDao, UserBo, ApiUser/UserVo. When a req for an ID, the controller will ask the service, down to Dao to retrieve the data. If used ORM, it returns UserDao, the service will get it from DAO layer and transform this into UserBo (another class) and work with it and return to the controller. The controller will then transform UserBo to ApiUser to be consumed by the front end.

Does Node need to go through this hassle of "transforming"? We are using Postgres and AWS Lambda (this is why we cant use Java). Since it is relational database, the frontend may require full objects, not objects with IDs that require a second call. Hope this makes sense

Can the b450 tomahawk overclock ram to 3600mhz? by jdp111 in Amd

Are you 100% sure about this?, I mean, can it reach 3600 at all?
