What is wrong with this circuit?

When powered by 5V battery all is good.

What is wrong with the circuit where AVR is powered by 5V regulator? Videos show results.

Code:

// the setup function runs once when you press reset or power the board

void setup() {

  // initialize digital pin 1 (ATTiny pin6)and 3 (ATTiny pin 2)as outputs.

  pinMode(1, OUTPUT);

  pinMode(3, OUTPUT);

}



// the loop function runs over and over again forever

void loop() {

  digitalWrite(1, HIGH);

  digitalWrite(1, LOW);   // turn the LED on (LOW is the voltage level to turn on TIP117 PNP Darlington)

  delay(250);

  digitalWrite(1, HIGH);    // turn the LED off by making the voltage HIGH 

  digitalWrite(3, HIGH);

  digitalWrite(3, LOW);  

  delay(50);              

  digitalWrite(3, HIGH);    

  delay(100);             

  digitalWrite(3, LOW);   

  delay(50);              

  digitalWrite(3, HIGH);    

  delay(100);             

  digitalWrite(3, LOW);  

  delay(50);              

  digitalWrite(3, HIGH);    

  delay(900);              

}

Re: What is wrong with this circuit?

Is this using what is known as a picaxe? I have been looking at those somewhat, just not sure where to start with them.

Flasher looks fine to me.

Re: What is wrong with this circuit?

Just using an ATTiny. coding is dead simple for strobe/beacon.

Got the issue sorted out as it was "flashing off" not "on"

It is back to this flashing pattern with AVR run from 5V and lights from 6.6 versus the bad flashing pattern when trying to run it without the extra circuitry.
