Project JCN-9K: Concluded

And here the final assembly:

Project JCN-9K: Arrived

The kit I bought on Ebay arrived. I built the kit in one day. Very easy and beautiful, just the case is boring, but as soon as possible I will change it.
The pieces:

Tubes:

PCB:

Soldering the components:

And the final test:

It`s Alive!!!!!!!

PRIME: Top Screen

Same process to print the top cover:

And checking the circuit, continuity.

Only one problem found, a miracle!!!! Using soldering the problem was fixed:

PRIME: New PCB

Well, after several problems trying to print the circuit using normal paper and photo paper, I decided to use a transparency paper. I found one step-by-step on the internet showing how to use this method. Print the circuit on a transparency paper and using a hot iron the circuit pass to the PCB.

Perfect!!!

Here my tip to hold the PCB to corrode: wine cork

PRIME: PCB

I am having several problems with my PCB. As the original project the lines are so small and are close each other, the corrosion process kills 2 PCB. Doing the continuity test I found several circuits interrupted. One solution is use soldering to fill the blanks, but as the lines are so close, another problem appeared… short-circuit! As I said, 2 PCB lost.

PRIME, JCN-9K and SPITFIRE

As I am conducting 3 projects in parallel, I will give names for each one as follow:

-          Project PRIME: The 6 digit clock, based on Andrea’s Instructables DIY.

-          Project JCN-9K: Single digit clock

-          Project Spitfire: Nixie kit from England

JCN-9K

In parallel I decided to develop another project, one Nixie clock single-digit. For now I will call it project JCN-9K. This clock will use a big case as a box, so space will not be a problem. So following one friend’s orientation, I will use one mobile charger to provide 5VDC in my project. Simple and cheap.
