Dimisloane Electrical

Hi, I want to build a simple electronic circuit for a college project.
It should be analog or mixed (not entirely a digital circuit).
It must be simple and fast to build but not as simple as an op-amp voltage comparator.
It must work!!! Especially at the exam time.
I want the circuit diagram and component numbers of the circuit, along with tips, a photo of the circuit maybe, ….
Please, suggest one such circuit, and don’t tell me about electronics sites where I can search for circuits

here’s a site with hundereds of Circuits Collection . it’s classified and arranged so you can navigate it easily & pick the one that suites you :

Good Luck

What do you think of my poem?

“Endless Roads”

Bristled green trees veil
endless, entwining roads.
Whispers drench
paved trails.

Headlights swallow streets below,
sky emblazons goldenrod.
Hearts beat in a void,
traffic crawls to a defined slow.

Red lights gleaming.
We wait in line,
our minds ablaze,
the engine steaming.

Lives unknown,
feelings unexposed.
Colors streak
muscle and bone.

Which lives have touched each skin…
left imprints, memories?
Who calms every fire
that emerges from within?

Pain scars
with invisible ink.
Memories unseen
by eyes in these cars

Green lights shine in the eve,
emotions slither pathless roads.
Tainted souls are hidden,
eyes will never cease to deceive.

What do you think it means?
And any suggestions/things to change?

Your work is very good easy to read and understand> I would have you change not one thing.
Just continue to write and expand your mind and its horizons, you have a gift use it wisely.
