...or, Go Back...
...May 17th...They're baaaaaaaaack...
Build your very own Numitron clock like this one:
Just add your own tubes, tube sockets, and 9Vac (1000mA) power supply.
Kit includes 7x3" PC board with solder mask and silk screen and all components, including:
47 diodes, 13 transistors, 15 resistors, 5 capacitors, 1 diode bridge, 1 resistor sip, 5314N, socket, 2 switches,
3 pushbuttons, pinheaders, and four standoffs to place this in your own enclosure.
NO TUBES, SOCKETS, or POWER SUPPLY INCLUDED...
...But you get all this pictured below (brand of parts may vary):
Pinout is for RCA DR2000/Apollo DA2000 tubes or similar.
Will accept both the standard tube sockets and also the smaller footprint ones from
gas-pump and circuit boards.

Functions include time set (fast, slow, and hold), 12/24 hour, 50/60 Hz, and bright/dim selection.
Dimming is done with diodes. Or you can use your own LM317T (not included) for voltage regulator dimming.
Cost of this kit is $56.00. The cost of a kit WITHOUT the MM5314N is $42.00
The cost of the board only is $20, which includes only the resistor SIP and bridge
Shipping is $7.00 priority shipping with insurance within the U.S.
Overseas must inquire about shipping cost -
Paypal (preferred) or money order only.

NEW FEATURE:
 |
Pinheader holes under the normal socket holes! |
So now you can use DTF104B's - or other Russian tubes:
(I can design boards, but I hate packaging these things :-)
This is a board and kit designed by me, as a hobby.
Assembly instructions will be provided. I will answer questions as
fast as I can if you get stuck.
The MM5314N's are new old stock and tested before they are packed.
Due to limited quantities, I cannot sell the MM5314N seperately (sorry). I have no tubes to sell either - but they can be found on Ebay.
This kit will not drive high-voltage nixie tubes - only low-voltage 7-segment displays such as the numitron tube - or minitrons.
Final Rev.F board - built with pinheaders instead of bases (top)
