what kind of tin would work?

You used a 200mm as circumfrence but for you to draw a circle with that circumference with a compass, u needed to find the radius of the circle. Using 2Πr = circumference hence radius is equal to circumference/2Π and you got 4mm as you radius. Good but how did you trace 4mm Along the curve on the circle? I mean how did you draw each teeth on the gear.

Please explain how you drew the cogs...

Nice first comment by the way

Good job...Nice working!! Can you please name the materials which you used ?

The gear is easy... but MATHS IS NOT EASY

What is the each gear teeth crest height; since you have drawn the outer ring at a particular radius from the center ; what was the distance between the inner circle and the outer circle. it seems that the triangle of the teeth seems to be 30 degrees on all sides. give the outer circle radius.

Good review. Sound quality is bad.

Wow

Like how you make the gear.

You've used the actual working that is used in real school bell.good job..

Was hoping you’d make another gear to fit in with the other one for a gear system but eh at least it works

I am sure you can still buy handbook with all info you need on INPLIX. Just google it.

This isn`t a version B? The TDA7297 I`m looking at doesn`t have a socket for a power plug and the 3.55mm input is on the right side, not in front. And the Drok 7297 has this layout but cost ten times more than this:www.ebay.com/sch/i.html?_from=R40&_sacat=0&LH_FS=1&_nkw=TDA7297+Version+B&_sop=15 Could you link to the specific one you`re using here? Also if you know what the differences are I`d like to know :)

That amp can easily over power your speakers. Try to find drivers that can handle 15 watts each.
