Soldering Smoke-absorber Powered by Single Chip

this is a small "smoke-absorber" which is used to absorb a small account of smoke. (i was going to throw this candy box but it dawned to that it could be something useful)

Step 1: Drill the Box

we need to drill the box

holes are 4*5

windows 1*front 1* back

make sure the two windows are right opposite to guarantee the air/smoke flow easily.

Step 2: The Single Chip (16 Pins)

we need a single chip (16 pins) to display numbers on the LED.

then fix the chip on the front, you could use clue,just place it well in the hole.

Step 3: Make a "mesh Board" Using Acrylic Plate and Pin a Fan in It

heat a Acrylic plate til it make the same curvy lines with the box, cuz we need to put into the box.

Drill as many holes on it as possible, to make the air and smoke flow as free and fast as they can.remember to drill a hole in the center of the plate for a motor. then put the small electric-motor in the middle of the plate.and connect the fan.
