Yes...yes... a fine DIY attempt. But the result is normally predictable, when constructed by amatuer diy'ster.
The result could be like the above mentioned, major short of major component, costly damage. Or the project works but not to expectation. Or the works somewhat, then blows easily. Or at best works with some minor glitches.
Let me remind everyone that, to undertake such a project, you must be more than an amatuer. Even for me who dabble in electronics circuit almost every day, I will tell you that I will make mistakes doing it first time too. Just little chance of fatal mistake only.
It's just even not remotely as simple as installing the motherboard and components of a PC to make it work. Which I see plenty of disaster cases too.
Kits maker and sellers will make it sound simple, just because they want you to buy their kit. They will not ask you in depth if you are skilled enough.
Good luck. :wink:
