I'm opening this new topic to discuss crowdfunding related things connected to the open source project that is active for some time here.
The project is "positioned" to bridge the gap between the DIY and professional worlds, and have a great potential to disappear in that gap or become an example how to combine the best practice from both worlds
.
The campaign will be conducted on the CrowdSupply and I'd like to hear your opinions about pledge levels. First please note that I'm not going to offer a completed solution. The reason for that is CE/FCC certification that is very costly and for 100 units that is campaign goal it could make a whole calculation completely unattractive.
Also please note the campaign is conceived as group buy to achieve few goals:
I was thinking about the following pledge levels (the final number and contents will be set in accordance with your wishes):
Thanks in advance for your valuable inputs.

Also please note the campaign is conceived as group buy to achieve few goals:
- Manufacture assembled modules (combined they have almost 800 items and that is far too much for many DIYers/makers despite the fact that DIY-friendly SMD packages are solely used)
- Manufacture compact metal enclosure to mount safely all parts and
- Decrease the cost per unit
I was thinking about the following pledge levels (the final number and contents will be set in accordance with your wishes):
- Set of bare PCBs only (4 of them, 2 layer)
- As above + metal enclosure (with other metal parts such as TFT display support, AC/DC modules support, channel's heatsinks)
- Set of assembled PCBs only
- As above + metal enclosure set + wire harness
- As above + TFT display + AC/DC modules (2 of them)
- As above + Arduino Due
Thanks in advance for your valuable inputs.
The crowdfunding should start any day now, and I decided to reduce number of pledge levels to four to simplify logistics:
Level A (PCBs)
Set of four bare PCBs that has to be populated using convenient SMT components for hand soldering.
Level B (Mechanical parts)
2U height metal enclosure predrilled and painted, nuts&bolts, wire harness and electromechanical parts (AC inlet, cooling fan, binding posts, etc.) required to mount and interconnect all modules inside the enclosure.
Level C (Core modules)
Fully assembled and tested set of four modules that represents the core of the EEZ H24005:
Include all from Level B and Level C and few items to make fully functional unit, or when listed all together that is:

Fully assembled and tested set of four modules that represents the core of the EEZ H24005:
- 1 x AUX PS module,
- 2 x Power board, and
- 1 x Arduino shield (carry Arduino Due or compatible board)
Include all from Level B and Level C and few items to make fully functional unit, or when listed all together that is:
- enclosure,
- nuts&bolts,
- wire harness and electromechanical parts,
- fully assembled and tested core modules,
- 3.2" color touch-screen display,
- Arduino Due board and
- 2 x AC/DC modules (115/230VAC) with power cable.
. That is a picture of what will be included into Complete kit (Level D):
Thank You and Stretch Goal Survey
Thanks to everyone who helped us reach our funding goal in less than two weeks! We still have over a month left in the campaign, so there’s plenty of time to exceed our initial goal and hit some stretch goals. There are a lot of features we’ve been thinking about and we’d like to hear your opinion. Please take our survey to help determine our stretch goals.
We’ll likely make decisions about stretch goals within the next few days, so please take the survey as soon as you can.

Encoder is coming ...
A short version of latest campaign update: the survey is now closed, and I want to thanks to all participants (250+). I got a lots of idea what can be done in the future. But some of them could be easily (and finally?) added into current design and that is mechanical (placement on the PCB) and firmware support for encoder. That is a first stretch goal that I can say with confidence that will be reached, firmware development for adding encoder is almost completed and I'm going to show that soon in a new video.

It's four assembled main modules without heatsinks that are part of the Enclosure and Assemblies pledge level (or Level B as titled before):
An externally hosted image should be here but it was not working when we last tested it.
Enclosure and asemblies pledge level
A respectable number of people decided to support this project by pledging for bare PCBs. Many thanks for that. I'd like to draw their attention in this final days to something what I believe is really worth considering once again and that is Mechanical assemblies that includes some parts that when are ordered alone could easily exceed the total price of that pledge. That is obviously customized enclosure, but not just enclosure alone, since it comes with two customized heatsinks (cut to size!) for Power boards and mounting rail for mounting TFT display among other stuff.
Without going into more details, I'd like to suggest you to check attached BOM of that pledge level where I marked in red few items that I found that is "difficult" (i.e. expensive) to order separately.

Stretch goal #3
I got today an updated quotation for the modules manufacturing. It' seems that with 207 complete kit we just "break even" few minutes ago for Stretch goal #3 (thanks to Mark O from Australia, and of course all of you people). The latest update is also published today with first video about EEZ Studio toolkit.

Crowdfunding campaign fulfillment
The crowdfunding campaign fulfillment is almost accomplished. More then 300 boxes are now on the way to Crowd Supply who is going to dispatch them to their final destinations.
The Complete kit comes with preload firmware v1.0 that now cover almost all functionality of the unit. Firmware development will continue and new releases can be found on the GitHub.
I’d like to thank once again all the backers for their support and patience. We tried to do our best and hope you like your kit.

Leftovers...
I made a list of parts that remains after campaign fulfillment. It's very limited and include various things from TFT displays, bare PCBs, enclosure parts to complete kits. If anyone is interested please contact me by PM. Your inquiry will be processed on first come, first served basis.
