Remember the Nixie Clock with LED Accents that we featured last year? Well our friend Muris has made a new version with lots of updates.

“Important hardware changes between this new version and the previous one are:

– Timekeeping is more accurate and is done by DS3231 (or DS3232) RTC IC
– There is no DS18S20 temperature sensor – the internal one of RTC IC is used instead
– Backup battery is not powering AVR anymore, but only the RTC IC
– There is no “slide switch” to control the alarm – now it is done in firmware
– Crystal on PCB is optional and can be chosen up to 16 MHz. It clocks AVR and GSCLK pin of TLC59401 IC
– Pin-compatible with previous version of Nixie “shields””
