WS2801 project

Firsts outside tests:

The WS 2801 modules  live now outside since 2 days...

Was somewhere very lucky : not enough cold (6°C), but a lot of rain since 2 days...
so here is the result this morning:








Happy man

Find a rubbish bin and fill it with water.. at least 500mm of water.  Sit them in the bottom for 7 days.. then report back.

I don't need to use these modules in a swimming pool or under water pessure  for moment...
Just to warranty the commun external weather conditions.
I made yet  the tests under water for half a day to check the cabling holes once finished (but without the caps).
Results were good : normal, i have double side wall inside and between then, once cabling was made i fill with resin. So no way to have water input from cabling....
Now, for the caps, i used silicon to seal them, and again,  the caps comes just over the second wall. So not to much possibilities to water enters in ( I made a lot of tests with different silicon products and i found the right one)
Why Silicon?
just to have the possibility to replace a faulty module and repair it in case...
I could use resin too, to be 100% waterproof and use the modules for swimming pools or fish plans, but once the module will dead direct to trash....
This is not my idea, and resin have some cost too, more than silicon. But maybe in the future i will try something in my swimming pool.... I have a lot of ideas pending ( just time is a pb)

If you insist, i can make full test on my swimming pool and take some pictures, i will it's interesting to do it, but what is the real insterest?
Just to prove we can use them in waterplans?

I don't search benefits or profits on that. Just wants to share my expereience and provide for those who are interest this PCB and ideas to use it  ( i don't need personnaly 5000 PCBs) for my personal use

I merely suggested the extended water test as a really good way of testing your water-tightness..   Just sticking them under water does'nt really prove much but under a little water really helps.

The other thing that you can do for accelerated testing is to put some in a container of water and freeze... If they survive that, you've got it sorted!

Submarine led lights?
Why not, but this is a "niche" market
Why not sending some modules to be iced on iceberg on north pole

i will open in the next incoming days a new post on pixel flood lights....

Another interesting application based on same modul 

For moment, i'll continue the tests with this pixel light WS2801 made from 'NOWHERE LIGHTS'.

Stay ahead

hey Henri,

I have Question how did you drive the Led module with the WS2801,
because I have Some led modules form onumen. And a controller the Mc-2100,
But this is not Working yet,

so I want TO know A simple other way to drive the Modules, do you have a solution,

and regarding to the Software from Onumen, I have it, works Fine do you need it?
 

[riri7707]

Hi EC,
to drive the modules, you can use the ONUMEN software directly.
Just use the right module option on ONUMEN software as you launch the SW.
In most of cases, you will need to transfer to SD card, previous to see the results

I used them on different ONUMEN modules without any PB...

The other way, is to use TP device/ but here i faced some PB about skips and flickering on actual firmware.
Not yet solved , but i expect some update in next weeks or months...

Nothing happened since December on that....

By other side, the modules works fine, as i used them for other applications..

I built more than 2000 units.... I have some available if you're interest on...

I will continue the post as i can, but actually i travel a lot through EMEA.

So just be a little patient, i think in 3 weeks i will go back to continue the WS2801 SAGA...

Thanks for your interest....

Cheers.... Henri
