The new nixie clock design is almost ready. It's a slim design for IN-14 tubes with good performance.

Features:

• Tubevoltage controlled by microcontroller.
• Tube dimming (by duty cycle) is possible, manually or with LDR.
• Under and over voltage detect on supply voltage.
• Built in memory backup
• Support for DCF-77 (and possibly GPS in later firmware)
• Serial port for firmware upgrade
• IR-Remote sensor for adjustment and control
• Tube illumination LEDs
• Case can be designed really slim
• 32.768kHz oscillator for good accuracy
• 8Mhz clock frequecy and relaxed tube-driving gives plenty of CPU time for effects
• Source code avalible
• Tested with IN-14 and IN-16. Work with IN-18 in progress.

Currently, sold as PCB only. Component kits can be arranged.
