I'm pretty new into electronics, But I do this mostly for educational purposes. Even if there are cheaper/more effective ways to build a power supply, I want it to be based of the LM317.
This project isn't finished yet, I just wanted to ask for any insights or tips that might make this better/safer. This is my circuit atm:

I was also thinking of using two extra pots for fine tuning the current + voltage.
My main goal is to have a simple power supply based of LM317 with both Current and Voltage adjustment. Thank you!
EDIT: If i use this design and what to add a transistor for increased load like this: https://embed.gyazo.com/e8ff3fd621ad4c0f7444903f880a4804.png
Where does the collector go?
EDIT2: One guy here suggested that i might use a wire-wound potmeter to control the current. Is there any other solution? Maybe controlling the current using an op-amp/transistor? If so can anyone show me an example circuit? I have checked out most of the datasheets but i don't think that they explain it that well. Cheers!
