I'm becoming fond of the polymer electrolytics in apparatus I build myself.
While they don't have quite the heat ratings
In my opinion, safety is #1 regardless of cost.
*Fuses* - If you are bringing line-voltage into your clock, use a UL-listed
power-entry module with an IEC connector (for the power cord), and an
integrated fuse.
If you simulate your design, you can calculate the RMS line current under
max-load

like to monitor the temperature inside the case adding a DS18B20 to the
