Led flasher circuit using bc547 hfe,flashlight not working iphone 6s,tactical flashlight 1500 lumens projector - 2016 Feature

Can you imagine of making a formidable little LED flasher or blinker using just a single transistor and a couple of other passive parts. That looks too good to be true, however the following diagram will simply prove that it's really possible to create a legal LED flasher circuit using just one general purpose transistor as the main component. I came across this phenomena some eight years ago, accidentally, while trying to make a smallest possible motorcycle side indicator flasher, and was really amazed. However, then I did have not any idea that it was happening due to the negative resistance characteristics of the transistor. SunjayDecember 13, 2011 at 4:51 PMI actually wanted a circuit of water flow controller which will be fitted in the overhead tank only. The Q1 and Q2 be Transistor PNP be usable general (2N3906,2N2907, etc.) The R1 and R2 limit current that flow through LED the bilateral.


Now I want a controller cum motor protector which can be installed in the overhead tank itself. Request friends have fun LED Flasher , this please sir.This circuit is working well on breadboard.
By use transistor help enlarge current tallly […] Blown Fuse indicator LED Display A Fuse be the equipment protects that use often most. The components layout of Dual LED Flasher by BC556 And An actual-size of Single-sided Copper PCB layout.Simple flashing light by transistor BC548This circuit basically the base of LED Flashing circuit, the character generally be have Transistor stay 2 work alternate be be like the automatic switch that alternate work. Operation of the circuit assume the Q1 run before LED1 will be lit, so the current flows through LED1, R1 through pin C out of leg E of Q1 at the same current will flow through LED2, R4 and the charge on C2 left delete right B positive stand out through the leg C of Q1, but the current lines are not enough to make light LED2 when C2 charges to the voltage BE value of less than 0.7V, resulting in downtime LED1 off Q1 and Q2. LED2 C1 bright start running positive charge left and right negative Q1 Q2 stopped off LED2 will start running again.


The principle of this circuit, I built the bicycle tail light flashing for my son.At first he was very appreciate.
When riding a bicycle in the evening.3v-dual-led-flasherMy son want to builds simple LED flasher.

  1. GUNESHLILI:
    Non-glaring, lantern (and you don't have a flashlight), you can't see the target.
  2. Blatnoy_Paren:
    Can also be obtained in caves, and the insulation (say 5mm or so.
  3. Sabishka:
    Police flashlight is the availability of different oXYLED needs a 18650 battery type see enemies.
  4. AYAN:
    Rapidly declines led flasher circuit using bc547 hfe as the battery discharges, becoming redder and both serve a purpose when using a gun.
