I bought some wick on eBay (China). Comparing to the one I get in the shop
here, it's kinda fluffy and absorbs way worse.

The one I get here is more tightly knitted, while the other one is more
sloppy. Flux could play a role too, but there is definitely a difference in
quality!

 Thanks !

 I could make a kit, but I not sure how well a pure SMD kit would sell ?

 I could make a through-hole version, but some components needs to sit
 tight (especially the power supply).

Flux (of some form) is definitely a must, personally I use a no-clean flux
gel. A loupe, good light and a reasonably
sized solder tip does the trick.

Most of the components are 0805 (resistors, caps, LED's), they are also the
smallest. The LT3757 chip in the power supply
is a bit tricky; small pin pitch and it has a pad on the bottom that needs
to be soldered to ground. I could eventually pre-solder
it on a kit, if I make one. Also, the 5V buck converter IC is pretty small
(SOT-23-6), but slightly easier to solder than the LT3757.

Maybe I'll release the schematics. It is based on the LT3757 datasheet,
with some modifications. Certainly not the cheapest supply, but it
runs smooth without significant heating..

Cool project.  I've done a bit of SMD and it wasn't too bad.  My soldering 
iron tip isn't the smallest but it was still doable.  The flux pen helped a 
lot.
That flyback power supply looks neat.  You could do that as a separate 
kit.  People are always looking for a good Nixie PSU.  
Would you be willing to release the schematics of the PSU?  I understand 
keeping it private if you would like to sell the modules.

[Nicholas Stock]

SMD (of reasonable sizes, not the really tiny stuff) is actually pretty
straightforward with a good iron and small tip. As mentioned previously,
for chips with small pin spacing, a flux pen is a life saver

Re: [neonixie-l] Re: Ongoing project: 12 tube date + time clock

[loknar28]

I would love one depending on affordability. I used to be afraid but after 
learning the techniques and discover flux pens that all changed. ;-)
The kits that GRA-AFCH sells are all SMD. I think they have nice kits which 
sell pretty well and they must since they have two stores on eBay.

I could make a kit, but I not sure how well a pure SMD kit would sell ?

I could make a through-hole version, but some components needs to sit tight
(especially the power supply).

Wow, that is one amazing clock.  I would bet if you made a kit, they would 
sell like crazy.  Great job.
