6 layer PCB FAB+Assembly - ONLY $2! :jlcpcb.com/?from=LeftyMaker
I decided to make my own breadboard power supply because I wasn't happy with any of the other options on the market. I wanted adjustable voltage, a voltage display, and safety features -- all at an affordable price.
So I partnered with JLCPCB to design and make this DIY power supply for breadboard use. It is based around the TLV767 chip and has output voltage ranging from 0.8 to 14 volts. Not bad!
Unfortunately, it may overheat under certain conditions, meaning that my PCB design does not provide enough surface area for cooling. Still, it is a good first attempt, in my opinion. It can provide 1W without issues, which is enough for many basic projects.

I playwd with electronics a bit when i was a kid, and now my children are old enough to start. Ive been thinking forabout little kits like this to build together... Anxieuouly awaiting version 2

It's not out of the question for a DIY kit to come out of this one day :)

why not add some screws beside the chip and then screw on a heatsink? or maybe you can make it so that the chip controls the output voltage using a mosfet, which should also be able to solve the problem

Hmm. I should look into your second suggestion. I remember seeing transistors used with chips like 7805 or 317 to increase their current output.

you have a lot of space for a 2mm chip... it's nonsense! you can use bigger voltage regulator! tiny chips are for tiny projects and... tiny currents 😊

The reference design by TI was much larger in area. I guess I trusted the 1A rating in the datasheet too much.
