well, got the boards in finally, all 50 of them. soldered up one of the boards and it looks great.

For what these cost I'm glad I made them. getting one of these ready to go take about 5 minutes of soldering and no time at all to add to a breadboard or protoboard. It's easy enough to program them in-circuit and they are able to take a voltage anywhere from 5v to 15v while also supplying a 5v supply for other circuit elements. it's also worth keeping in mind that these are still relatively inexpensive for what they are, here's the running total: 

$16.17 for 50 boards (shipping included) = $0.3234

$1.24 for attiny85 (assuming no bulk pricing) 

$0.17 for ams1117 (roughly) 

and lets say $.10 for the capacitors and headers. 

meaning the entire board start to finish costs $1.83 or just 47% more than a standard attiny85 project. Saving a lot of time that's well worth the cost in this case. 

I also took a video of one of these running a simple counting program for which the code is included at the bottom. 

#define F_CPU 8000000
#include <avr/io.h>
#include <avr/interrupt.h>
#include <util/delay.h>
void init() {
  DDRB |= (1 << PB2) | (1 << PB3) | (1 << PB4) | (1 << PB1);
}
int main(void) {
  init();
  while (1) {
    PORTB++;
    _delay_ms(10);
  }
}

see you in the next project! this one's been short and sweet.
