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.
Step 4: USB Hole
leave a particular rectangle that will suit your USB for charging.
Step 5: Melt Adhesive and Assemble
melt adhesive and assemble
make the parts tight, watch out the position of the parts that are close to the holes and window.
Step 6: Enjoy and the End
there is a on and off button on the top.USB is set. it is small and can only absorb a little amount of smoke, just for fun.
