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