I have been doing a lot of component placement work on the new scope
clock board. Tetris! This is what it looks like. The six square controls
with equilateral triangle dots are the oscilloscope knobs, and the
function encoder is at bottom center. The other square pots are trimmers
accessible through the front panel.

The HV power supply is at upper left, deflection at upper right, V power
lower left, computer at lower right. A big USB-B connector is behind the
lower right corner. RTC battery is at bottom.

The thru-hole parts (other than controls) are rear mounted, with all SMT
parts on the front. There will be 5/16" standoffs in the six outer holes
to mount the board to the front panel.

This is a work in progress.

Hey David, that looks great. I'm cheering you on.. BTW, I have a pick and place machine and a reflow oven, so when you get to the point of doing small runs look me up..
Cheers

David, how big is that center opening?

The hole for the tube is 3.25". I could make a 5" version if there are
enough tubes out there.

I plan to or adapt a little GPS board to be bolted to the top.

I have here in my stash of tubes, crts etc., 10 (ten) NOS D13-622GH CRTs
here in their original carboard box :)

I haven't been able to find much info on these CRTs on the web, though.
I would love to build a monster clock with all 10 at once..not sure I can
afford 10 of you kits, but looking forward to hearing the price, I am.

Dan

David,
 
Has a target price been set?
I am very interested since I don't have a scope clock yet.
 
So, full kit needed.   Clear case (obviously).
 
Also, what is the tube life expectancy as I might need to get 1 spare as well.
 
PS.  Is there going to be a feature to have it power off during certain hours, etc?
 
Michail

I looked in my Philips CRT book dated April of 1968 and it went as far
as D13-480. Perhaps someone with a later book may be able to help. Ira.

David, would you consider adding a socket for the nrf24L01+? Even if you don't implement any functionality with your initial software release, lots of options such as remote control and who knows what else, become available. And all it takes is 3.3v and connections to the SPI bus.

David,
If you do consider remote control, I would like to suggest you use an ESP8266 module, like the ESP-01.
These are very inexpensive($2), are plug and play(from a hardware perspective) run wifi, and can be loaded with an Arduino bootloader thereby allowing anyone to easily modify it.
The other 'radio' technologies are very proprietary and in my opinion have now been supplanted by this ioT technology.

Mitch,

The board has the following jacks on the right side, accessible form the
rear (the inside of the case):

SPI with 5V
Serial I/O with 5V
X and Y analog input
USB

I could also add I2C, if that's important in addition to the above.
