The kit I have available is a professionally made pc board and the components to populate it, including the ICs and the preprogrammed microcontrollers written with my firmware.

With the HV transformer option, a higher voltage is available which can drive CRTs up to 5" such as 5UP1, 5ABP1, 5CP1 and other similar types. A homemade enclosure is available for small CRTs. Size can be customized, please inquire. This is an advanced version (OSC4.6) that will drive both the smaller CRTS, (DG7-6, 2BP1, etc.) in "low voltage" (600VDC) mode and also larger CRTs, (5UP1, 5CP1, etc.) in "high voltage" (1,000VDC) mode.

There is also a port in back for gps module or wifi module input for automatic time / date set.

It uses a simple low voltage dual secondary transformer and a line fed voltage multiplier for the HV. I supply the instructions for assembly and a parts list with the board and components. You can download the Documentation, Datasheet and BOM from this page.

Some CRT types that I have used with this board are:

• DG7-32
• DG7-6
• 2AP1
• 2BP1
• LB-8
• 6Loi1
• 50HB1
• 7SJ33J
• 3SP1
• B7S2
• LO-247
• 3GP1
• 3Lo1i
• 1EP1

Many other small relatively low voltage CRTs may work with the kit.

Automatically sets for 50/60HZ. The display alternates every ten seconds between digital and analog style. The display also moves slightly every six seconds to help prevent "burn in" of the CRT. The microcontroller and all chips are in sockets for easy replacement.

It can be set for 120VAC (U.S. standard) or 240VAC (some other countries).

I will ship it anywhere in the world, but I cannot be responsible for problems and/or delays caused by customs in your country. International buyers, please send your address for a shipping quote.
