Amazing

Excellent basic function; could use "finishing touches"
For Turntable Strobe
For finishing touches I mean:
A. for use as it is currently embodied, some kind of casing, wrap, or cover so the circuitry is not exposed would be highly desirable as an option. Obviously this would be quite small, but some kind of small plastic sleeve/box would serve, and could be sold as an extra.
B. for an alternative use case, where installation in a turntable is the thing, providing the possibility for external power and "remoting" the LED would be ideal. Also in this case some mounting scheme would be needed to hold the PCB in place; either holes in the corners or some alternative arrangement.

Decent Breakout Board
For ATtiny84 development board

Easy to assemble and works well.
For ATtiny84 development board
After identifying the pins on the SPI connector and connecting a ISP device (USBASP or Arduino as ISP), one can easily burn a "boot" loader or application sketch. I found with the raw devices that one has to "burn" a boot loader to ensure the Arduino ISP timing functions work properly. The Arduino IDE "burns" a generic boot loader to the raw ATtiny84 (or 85). The Arduino IDE generic boot loader does not support programming by a serial or USB connection. But, it does work. With the generic boot loader, one needs to use a SPI connection. The raw devices have this SPI functionality built in.
The documentation does cover assembling the board. It needs to have diagram showing the SPI pin locations. This is not a major problem, if one has Volt Ohm meter to to determine the pins.
I am happy that I got these boards. They work well and come quickly in the mail
