| Completed clock on circuit boards. | |

| Processor, RTC, and power supplies | |
| Prototype of my nixie clock using an Atmel 89C51RC. The nixies are NH-14's driven by 74141 Russian type TTL drivers. PPS and backup time come from a Dallas DS1307. | |
| This is an earlier prototype using seven segment displays. Also in the picture is the SMPS for the 180v Nixie Anode supply. And the "hacked" out wwvb receiver. | |
| The first wwvb receiver came from an Atomic clock I bought at Super Target. | |
