Default 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);              
}
