A while back I purchased the Sparkfun function generator kit and frequency counter kit. I had originally seen the Nuxie kits, but they became unavailable and shortly after Sparkfun filled the gap. I built them up, but never did much with them. Over the last year I have made it a side hobby to build some of my own test gear:
Here is an Si570 RF Generator kit that I built into an aluminum chasis:

Here is a basic frequency counter kit built into the same chasis:

With the Sparkfun kits, I thought it would be fun to put them together into a single function generator unit. I used the same Hammond aluminum case. CNC'ed the front and rear panels for display, controls, AC power, ect. I did make one mistake on my width of the LCD window. I might cover that up with a little smoked plexi frame somewhere down the road. Here are some pictures of the build:
Front panel CNC'ed and everything installed:
Rear view of front panel:
Front panel pre-installed in chasis and starting to mock up the rest:
Wiring from front panel to generator board complete, including remote installation of all generator switches and pots:
CNC'ed mounting hole for standard power cord receptacle:
Installed +15VDC Meanwell switching power supply:
Here you can see the DC connection to the function generator board. I decided to keep the coaxial power jack:
I used SMA bulkhead connectors for the adjustable and fixed waveform outputs:
Both panels installed and power up check:
Completed project!
