Dirty Electricity Filter
After watching ScottiesTech.info video Make your own Dirty Electricity Filters! on YouTube I tried to make some.
Supplies
- 5 pcs induction cooker capacitor (5UF 275V-400V 1200V MKP-X2)
- 2 pcs 220k 2W 1% resistors
- 2 pcs 220pF ceramic 1kV capacitors
- wiring / file / soldering iron / energy saving box or big smart plug

Open Box and Remove Circuitboard
Unscrew the box. The smart plug depicted had triangular shaped screw heads, but can be opened with a small flathead screwdriver as well.
- tear off flatcable
- unscrew and remove big circuitboard
- unscrew small key panel circuitboard but keep the board and the screws
- scratch underneath the green led over the length of the circuit board with a utility knife and break off the top part of the board with a pair of pliers
- screw key panel circuitboard back in place
Remove Circuitboard Sockets
With a pair of side-cutter pliers cut off the sockets that held the circuitboard in place. With a utility knife remove any leftovers.
Place Capacitors in the Box and Solder Wiring
- put 4 of the 5 uF capacitors in the box topside down
- file a groove in the bottom edge of 1 5 uF capacitor as shown
- solder two wires each to 5 pins of the 5 capacitors (the capacitors have no polarity, so which way around they're placed makes no difference)
- solder the incoming live wire to one of the 5 pin wires, and the neutral to the other 5 pin wire
- both live and neutral get a 220pF capacitor to the black earth wire
- solder two 220k resistors over the live and neutral wire to discharge the capacitors once unplugged
