@dc42 Sorry, its the part cooling fans that keep turning on and off as the LED's turn off and on.

I have the Smart Effector v1.3 and have been using it for a while. Today it started to flash the LED's and fans on and off randomly like the whole unit is losing power.

I took the effector off, and it looks ok visually. I started tracing VCC with my multi-meter, and it appears that R7 is the issue. I am not getting any continuity or resistance across R7, which goes to RST on the ATTINY45.

Any recommended fixes/workarounds without having to replace the Smart Effector?
