Low cost var. out PSU with laptop adapter

I am not sure if I will always feel this way (I probably won't) but I haven't needed to improve my device. I mostly work with simple motors and microcontrollers which find my single output device perfectly appropriate. Accordingly I'm going to close off this project for now. If anyone is particularly interested in the final product, I will make sure to complete it, after finding the right enclosure (my current delay).

As described above, I needed a PSU for another project and only had one potentiometer. I added a 7805 for it's common use but now have an elegant little PSU with 2-17V variable and 5V linear output.

I am still waiting for a little flush capital to buy the components for this. I have finished my studies but find myself in a bit of limbo due to my obiligation to start working for Eskom (our local power utility) next year, no one will hire a recent graduate for only a few months it seems. But I am going to buy the components this week probably, for anyone still interested in the results :-)

I have most of the components except the potentiometers and housing (I have multiple old laptop adapters luckily) and am just looking for time and these components to somplete the project.
