I westdave, also have the E1T tubes they have been in the drawers a
long time but there are 6 of them they are looking for a kit to come along

Hi All
Over the last year Nick Stock and I have been working on a clock
using six E1T decade counting tubes. I have been working on the
electronics and firmware and Nick has been working on the overall
presentation and case for the clock.
Here's a preliminary view of the clock:
This show a development test case using laser cut acrylic. Our
final "built and tested" case will be black anodised machined
aluminium. Over the top will go a clear acrylic cover to protect
the tubes. The PCBs are green solder mask prototypes but the final
boards will be black.
The project has reach the point where we are about to order the
PCBs and we will then work toward having the clock available. We
should have the clock available all the way from just bare PCB
sets to fully built and tested.
The main points about the electronics design are - SAM3X8C 32 bit
microcontroller, firmware written in C using Atmel Studio (GCC
compiler), PIR to sense room occupancy and to shut down/wake up
the clock, chimes based on playing stereo WAV files, bling-bling 3
colour led modules, IR handset and rotary encoder user controls,
automatic time setting using WIFI or GPS, RTC using TCXO, power
supplies etc
All will be open design and open source firmware.
The purpose of this email is to try to gauge interest in the clock
to help us get the right number of PCBs made. So I would
appreciate an email from any one who has some E1T tubes and might
want to build a clock with them. _Such an email will be on a
no-obligation basis_. If you choose not to buy any PCBs or a kit
then that choice is still yours to make.
It is unlikely that Nick and I will be selling any E1T tubes as we
only have enough for our own clocks and for what we hope to sell
with built and tested.
If you want to see more about the clock, then this link will take
you to a work-in-progress case 3D render:
https://a360.co/2U5lDPZ
And this link will take you to a dropbox where you will find some
rough documentation, Eagle files, work-in-progress 3D printed
parts, DXF files for acrylic cutting and so on:
https://www.dropbox.com/sh/6eoeioya5ljh116/AAClQipdvQUYd7n6a6jbGigua?dl=0
<https://www.dropbox.com/sh/6eoeioya5ljh116/AAClQipdvQUYd7n6a6jbGigua?dl=0>
If nothing else, you will see from the dropbox what we feel being
"open" is all about.
So, if you might be interested then drop us a line, there is no
obligation on your part, the only obligation is on us to keep you
informed of progress and, eventually, the kit options and prices.
Enjoy! Questions?
Nick and Grahame
