Hello friend
today in this video i will show you how to make easy cheap and reliable powersupply for your arduino projects, this is a capacitor dropper type power supply, although it generates 240 mili amps only but it is enough to powerup your microcontroller or development board, it occupies minimum space thus we can minimize our projects, It is Cheap, reliable and long lasting power supply that we can run 24 x 7 with out projects,
Yet it its dangerous,
1) Never switch on the powe rsupply without load.
2) Never interchange Live wire and neutral wire.
3) Never touch the terminals of the components.
Advantages
1) Low Cost
2) light Weight
3) minimum Size
4) Long lasting
Disadvantages
1) Low amp. output
2) cant swap live and Neutral wire
3) can apply electric shock.
List of Components
1) Polyester Capacitor 185j400V
2) Resistor 330 K
3) MD107 Bridge Rectifier
4) Pf 104 x2
5) Capacitor 1000 mf 50 volt
6) Capacitor 470 mf 16 volt
7) 7805 Voltage Regulator
8) 12 volt Zener diode x2
9)69 Ohm Resistor
10) LED for Power indicator
