For a long time now I have been seeing this machine lying around in my house. The vaporizer cartridge got over sometime back and I never bought a new refill.

I then thought of using it for a different purpose. First thing that came to my mind was to turn it into a night lamp since I felt its cartridge can be a very good light diffuser.

Finished lamp can be powered directly through the mains [220-240 volts]

For those of you who are not very familiar with this machine, it is used as a mosquito repellant!

Step 1: Things needed

• Mortein Vaporizer Machine & Cartridge
• 3 White LEDs
• 8mm clear pipe [length 2 inches]
• Sand Paper [Fine]
• Solder Gun
• Solder Wire
• Pliers
• Screwdriver
• Insulating Tape

Great post... Thanks <br>
Nice one Ram,<br>really innovative<br><br>The circuit from http://hobbycircuits.blogspot.com/2008/03/220v-line-powered-led-lamp.html will be good<br><br>the 0.22U capacitor will provide around 14.8K impedance at a frequency of 50Hz+ the series resistor of 1k added to it will provide around 15 to 16 milliamp thru the LED, at 230VAC , 50 Hz ,<br>assuming the forward voltage of the LED to be around 4 to 5 volt , the power in the LED would be around .075 watt, so a series string of 3 LEDs will consume around 0.225 watt, which is really Green.<br><br>The power thru the LEDs can be increased to around 25 ma by using a capacitor value of 0.33u/600, but be carefull to check that the LED is rated for the higher current, else you will end with burned LEDs<br><br>If this has to work from a 110 VAC , 60 Hz input, the Value of the capacitor<br>should be increased to 0.33u/600 or to 0.47u/600 , to keep the same amount of current thru the LEDs<br><br>And by using the Capacitive drop technique there is no power loss, a series resistor of 14.8K would have dissipated around 2.75 watt, (R1 will still dissipate around 0.3 watt)<br><br>AND AS THE NEUTRAL IS COMMON , DO NOT TOUCH, RISK OF ELECTROCUTION
Thanks for sharing this info, this definitely helps me building my knowledge
<br> I'm quite sure I haven't seen anyone do this before, nice job - I like it.<br> <br> Do I understand correctly that you're using the heating element as something like an ~8KOhm resistor?<br> <br> L<br>
To be honest, I have no idea what resistor is being used there. I tried to open one of the heat sink sleeves but it was so tight around the resistor that while removing all the color codes came along with it. so there was nothing for me to look at! Some articles on the internet say that the minimum need are a series a high voltage capacitor and a resistor. A diode also in parallel with the LED in reverse polarity connection.<br><br>http://hobbycircuits.blogspot.com/2008/03/220v-line-powered-led-lamp.html<br>
