Most of you guys asked about Radio transmitter circuit diagrams.Today I;m going to give you a transmitter which is operated with 1.5 power.and another thing is this circuit runs with 2N2222 .after building up this circuit diagram you can check this with any radio set. Note # Build this circuit on a p.c.b # Don't supply over 5V # We don't get any responsibility of miss using this circuit.This is any for educational purposes

Most of you who use 110V asked me LED light circuits which can be operated with 110V.By using this circuit you can light up 4 LEDs form110V.Use white colour LEDs Note:   # If you are under 10 don't try this circuit   # Be careful when you deal with 120V  # Build this circuit on a PCB

I've been testing the PIC32 DMA recently. The PIC32 has a DMA (direct memory access) module that allows the data transfer in the PIC32 without CPU intervention during data transfer - thus freeing up CPU to perform other tasks while the data is transferred). First, I did a simple test to just see if it works (I've also done some DMA timing testing - I'll talk about them soon in another article). The first test was to just use the DMA module to transfer data from a constant array (from FLASH) to PORTA (LATA for output). This would be visually seen as LEDs connected to PORTA blinking. The code is: //================================ /***************************************************  * Programmer: Syed Tahmid Mahbub  * Target PIC: PIC32MX250F128B  *  * Date: 05/08/2014 - 05/10/2014  *  * Program to test DMA operation  * DMA will transfer const (from FLASH) to PORTA  ***************************************************/ #include "plib.h"  ...

Most of guys asked about 230V flashing circuits so I suppose this would be the most easiest circuit diagram.Here we have used common multivibrator circuit and two 3V relays.You can connect your AC line via the relay.( Use relay as a switch) Even the persons who use 110V can use this circuit.Not only that If you like to attach this circuit for you car you can  attach 12 v to the relay (as a switch).This circuit can be operated with 3V power supply. Note:  # Don't supply over 4V  # Find best relays  #Build this circuit on a PCB
