20 white LEDs connected in series circuit is formed. 220V. Pointing 310V AC current. DC (1.41X220), we obtain and the “220-volt Led Operation” in article 310-volt outlet using the account to be used’re placing stones resistance.
My hands, I had a great saving bulb container I use it to mount and bore a sticker I cut according to his section.
CAUTION Be careful is working with high voltage capacitor circuit connections + Please note – If you connect the high voltage polarity may be large explosions before running the insured Power Line circuit, wear protective goggles

Simple cheap pic programmer Circuit
I tested a simple and inexpensive serial pic programming circuit. The foundation mesh “JDM Programmer” pic of the programming circuit. RDC Programmer name resistors, diodes, capacitors, circuit test is based on the fact that I did with the PIC16F628 com cable directly from the PC using RS232 socket on the rear of the chassis I’ve used the program IC-Prog
There are a lot of programs on the programming card support, but inside there was rdc selected while JDM attempt did not trouble
