Circuit comparison in everycircuit

Click For Summary
A user attempted to recreate a circuit from EveryCircuit but encountered issues with functionality. After comparing their reproduction with the original, they identified a discrepancy in the dimensions of a component, specifically the width of an n-channel MOSFET. Adjusting the measurement from 1 μm to 1 mm resolved the problem, allowing the circuit to work correctly. The user acknowledged their inexperience in electronics and considered taking breaks when facing difficulties. This highlights the importance of attention to detail in circuit design and reproduction.

Hi.
Found a circuit pre made at everycircuit and tryed to reproduce it for scratch but the new circuit does not work. I am as new to electronics as one can be, so that is why i ask if i don't understand something with these circuits or is this probably a bug with everycircuit?
In image left is reproduced; Right original.

Credit for original circuit: bixio @ everycircuit

PS. This was the closest forum section i should find, Did not intend to wrong post is so.

What is this thing in the right lower corner, that is 1 μm on the left and 1 mm on the right?

Did not se that. Changed the reproduction to 1mm and it works. Thanks.
It is the width of an n-channel mosfet, That is all i know.
I should probably start taking a brake when I am stuck.

Thread 'I thought it was only Amazon that sold unsafe junk'

I grabbed an under cabinet LED light today at a big box store. Nothing special. 18 inches in length and made to plug several lights together. Here is a pic of the power cord: The drawing on the box led me to believe that it would accept a standard IEC cord which surprised me. But it's a variation of it. I didn't try it, but I would assume you could plug a standard IEC cord into this and have a double male cord AKA suicide cord. And to boot, it's likely going to reverse the hot and...
