Cogwheel Nixie System

• Latest refinement of a very stable design• Drives up to 8 tubes with up to 16

segments (includes B7971)• On-board sockets for 7 IN-17 miniature

nixies• Connector to drive separate tube boards • Low parts-count; 3 HV drivers in stead of

32 transistors

Cogwheel Nixie System

• Optional Bluetooth module• Non-volatile clock accurate +/- 1 minute/year• Uses ATMEGA 328• Compatible w/Arduino development tools

On-board Tubes

Off-board Tubes

•These tube boards are already designed and working.•Plan to offer them on batchpcb marketplace initially
