This picture shows the 2AP1 running
digital program created by oz2cpu. In order to do this, you need the
chip programmed with his firmware and it has to be exchanged for mine.
I have a youtube available demonstrating
the method to exchange the chip. Add the chip to a 2" scope clock for
backup included !
This is a 3JP11. The fast blue phosphor is a rare crt color.
This is a VFD (vacuum
fluorescent display) underlit with the blue leds and using green leds
for colons. This is the prototype using IV-12
I use IV-11 tubes (solder-in) coated with blue and blue led colons for
the final version.
This is a new variation of the
Cube, where I use IN-16 nixies and a design like the six-digit Nixie
clock with a removable shroud and blue leds. This is the prototype.
This is the square crt 6LO1i, it
the smallest crt that can still display the analog clock face. It is
a blue led. The screen is touch-sensitive,
touching it moves the display a little : )
Battery backup included !
An oscilloscope clock built with a
crt (blue-yellow phosphor)
