This model uses a motion detecting rechargeable light and small 5v fan to circulate fragrance depending on movement.
Fragrance oil is added to a cotton pad in a cartridge that slots in the top.
Also creates ambient light depending on the transparency of the material used
Can also be powered via USB
Items required: Full links below
Motion detecting light 10cm\6 LED
5V Fan 40x40x10.5mm
Assembly Instructions
The fan needs to be soldered to the circuit board as shown in the pictures
The positive wire of the fan is soldered to the +battery and the negative to the bottom right leg of the U2 chip, the easiest way to do this is to solder to the resistor as shown.
Put a piece of cotton wool pad in the cartridge and add a few drops of fragrance oil
The fan and light will activate when movement is detected and will run for about 15 seconds if not retriggered. Ideal for bathrooms!
There is room to install a bigger battery if required
I am not an electronics expert, just a tinkerer/maker so if you see a problem let me know, but it works fine for me :-)
Please post your makes and let me know how it went !
