The PCBs

These seem to work rock solid now with the current kernel. All the hardware features we tested work fine, all bugs seem to have been fixed, so I guess we can really call the PCBs fully finished and ready for mass production!

Nikolaus made one small change / bugfix to the Display board: It was flickering sometimes under high load. It turned out that the PWM wouldn't handle the power the LCD needed which caused the flickering.
And it was also shuttering when the display brightness was dim due to the frequency the PWM used.

The PWM is now replaced (just one chip on the display board) which increases the maximum brightness of the LCD and also provides a smoother, flicker-free backlight.

We also received a production report from Global Components which show potential issues for production (pads too close to each other, etc.)
Luckily, these are just small changes, the layout doesn't change, only some components are being moved around a few 0.2mm, so no new prototypes are needed (no worries )

Nikolaus is now working on wrapping up all the production files: Cleaning up the part lists (some parts have changed), implementing the results from the production report into the design files, etc.

We plan to have them finished within December (we don't know if it works out before or after christmas), which means I DO plan to greenlight the mass production of the PCBs this year!

So much for the good news, now the ugly part...

The cases

Geez, that topic is pretty annoying and time consuming.
While all stuff HAS been picked up by the carrier, our beloved company has held them back as they first wanted to receive the final payment (last changes and the 500 produced transparend cases).
Of course (you know their speed by now), it took them 2 weeks to let me know the costs and another 2 weeks to confirm my payment.
My contact in Greece is now visiting them twice a week to speed things up and thinks that everything should be resolved next week...

Seriously, I'm making more then three crosses when everything arrived at UniquePlast...

Anyways, it's very annoying, in worst case I'll fly to Greece again (as they always seem to move forward faster when I'm around), but I'm also planning to get these moulds moved to UniquePlast within December!

I'll let you know as soon as I receive more details from my contact (should be tomorrow or on Monday).

I'm sure we can solve that, as we've solved other things as well (remember the huge task moving the parts from CC to Global Components when we moved the production to Germany...?)

Few hours later.... and we're finished with everything. We will pack up the moulds tomorrow and arrange pickup for Thursday morning, just to be safe (we don't want that the courier pops up while we're still packing up).

Everything worked out well so far, even though it was quite a long discussion.
Will post a more comprehensive update later tonight... now I seriously need some alcohol

Maar op een gegeven moment wordt het wel tijd. Ik heb ook Kickstarterprojecten waarbij er na 2-3 jaar eindelijk iets komt, tof, maar er zijn er ook waar je al 4 jaar alleen maar beloftes hoort en er nooit iets ven de grond komt, behalve zo nu en dan een excuus.

The production of the first PCBs can start middle of September, btw, everything will be there then.
Then we just need to finish the case, the logo, packaging, etc. and it's time to ship.

I'm planning for the full production sometimes end of October maybe and the preorder-prototypes should go out early September.

Geen idee of dat hier moet/mag of er een speciaal topic voor is maar dit ziet er wel behoorlijk smooth uit

Probably end of July / early August.

The PCBs have all been populated already, only waiting for the heat spreaders and the case coating, everything else is already done.

Ik weet dat het cpu-board updatebaar is, maar is ie nu niet al lang achterhaald?
