I spent an enjoyable evening installing my Iowa Scaled Engineering fast clock which includes two wireless slaves. 

The beauty of the ISE setup is its simplicity, ease of installation, and minimalistic look which fits my personal aesthetic perfectly. 

I started by measuring the printed circuit board footprints so that I could make accurate cuts in the layout fascia. This was critical because the faceplate screw holes are fairly close to the circuit board and I needed to make sure not to cut too much fascia away. I made paper templates from the measurements and taped them into position; scribed the outlines onto the fascia; and carefully removed the wood with my DeWALT oscillating multi-tool. 

The DeWALT oscillating tool makes quick work cutting through the fascia.

I have a separate 12 volt power supply that feeds several of my auxiliary features around the layout, so I ran the feeders to the main clock and I was up and running. 

I like the clean format that ISE has built into their system.

The two slaves are also powered by the 12 volt supply. They tie into the main clock via XBee receivers which work very well. Again, the slaves are clean and minimalistic which is a great look.  

I plan to run the time ratio where an eight hour work day is condensed into roughly two hours of operating time.
