Mod edit:
See also Carte multifonctions SBC_IO board pour arduino, which is in French. As it has many replies and contains what might be useful information I have left it where it is, but it's closed as it is a duplicate of this topic. I can't merge them as that would produce a topic in a mixture of French and English.
I see that censorship is everywhere ... I propose a collaborative project so that the greatest number can have access to a board for Arduino that interests a large number of makers.
Continue to censor, it will not prevent this board from being developed, and without a collaborative project, you will simply pay double for it!
For those interested in this card "carte-sbc-io-multifonctions-universelle", please contact me by private message.
I’m not sure why there’s any issue with censorship, as I never saw your post. Just to let you know, what you’re working on can actually be done using chips that are available for less than $1.00 US. These parts come with configurations from 1 to 32 inputs/outputs and might simplify your design.
Since the header on this thread states that this is @banjo33333’s first post I am guessing that either an attempt under another ID was made that violated the rules, most likely spam.
There are multiple ways to accomplish the stated objectives, RS232, RS485, AND CAN come to mind immediately. Not to mention SPI and I2C. How about USB?
Yes I flagged it as spam. That's what it looked like to me. It contained a link to a web site that promoted a commercial system. Spammers often do this to get their link promoted to gain extra rankings in a search.
What I saw on there was just an attempt to get people to pay over the odds for accesses for well known techniques of interfacing. So I flagged it.
Any post flagged as spam goes to the forum moderators to take action either to ignore or take action. Who looks like they changed something.
This is not censorship, it is keeping our forum free from spam.
Also it was a French link in an English section of the forum.
Yes I think he registered again and added a few more 3s to a new account. Again a cardinal sin in these parts. Known as a sock puppet.
Hello, to answer your questions: yes this project is proposed on ulule, no it is not spam, and not a commercial project I do not need money. It is just a collaborative project that must be able to serve as many people as possible. And yes, it will be possible to connect this card to an SBC or a PC or a MAC by UART and by USB.
You have to admit you kind of set off on the wrong foot there, although I can see how the quote above was a bit of an unfortunate formulation of something you perhaps didn't really mean that way.
Still, for a non-commercial project, I'd imagine it would be possible to simply release the technical documentation so anyone could replicate it. Marginal cost in terms of PCB manufacture etc. would be for the user to bear.
Maybe we have a different understanding of 'commercial'; if you want to recoup the cost of developing something without necessarily running a profit on the activity, I'd still call it 'commercial'. After all, you're investing (in cash and in kind) and then recovering that investment through sales. That's business. Not wanting to run a profit would still make it business (just bad practice from an economic viewpoint). We have a lot of business activity masquerading as 'non commercial' in society.
The question is where the project is stuck. What is/are the bottleneck(s) you're trying to navigate?
I want to help society and especially makers, but the development of such a project will last at least 6 months. So for those who are interested, it does not seem abnormal to me to participate a minimum in the financing of this project. This is the very essence of crowdfunding. Otherwise, I develop this card without asking for anything, and in this case it will simply be sold at the market price. I came to this forum (and others) to make the project known because if it remains unknown, it will simply never see the light of day.
By this, do you mean to say "I think it's normal that I ask for a financial contribution to my project"? I'm just clarifying, because your literal formulation refers to your own financial investment in the project.
The only thing the term literally means is a group of people putting money into something. In practice, it is used for many purposes, ranging from arts projects, personal health/improvement projects (cf. gofundme) and first and foremost many business ventures.
In any case, I notice that the emphasis of your question has moved to the financial investment people are supposed to make in your project. People tend to invest only if they understand what they're investing in, and what it's going to yield (for them or for someone/some entity they care about). So you may want to clarify a little:
What kind of investment you're expecting - in cash, how much do you ask? "In kind" (i.e. non-financial investment): what kind of input in terms of knowledge, experience, assets & work are you looking for?
What is your project going to result in? I.e. what exactly is it going to yield, what does the final product look like, how will it be produced and marketed or otherwise made available to the community, and at what cost?
How do potential investors (in cash and/or in kind) benefit from their investment? Do they get anything in return? What is the basis/rationale for their investment?
The main reason why it may not see the light of day is that while you've made the existence of the project known, you've told virtually nothing about what it's about. We have to literally pull the critical information out of you! How do you expect this thing to fly if you're so secretive about the whole thing?
The same message was posted in the French section.
Unfortunately @banjo33333 did not answer the technical questions.
The questions were mainly about the serial/usb commands to drive the component (LCD, UART, GPIO, ...)
I closed the discussion in the French forum as there was no technical feedback from the OP on questions and the overall tone of the conversation was going south.
We don’t need duplicate postings .
If OP wants to provide more info on his project (esp how he foresees the software part to work + answer the feedback he got on the hardware choices / cost) he can do it here.
That would help clear out the feeling that it’s ill designed and closer to a scam than a community project.
Why doesn't OP develop the whole thing on his own funding and then go to market with it and see if it's successful. He gave target list price anyway.
I’m completely fine with the idea of raising funds on crowdfunding platforms like Ulule (his project is listed as "Universal I/O Board for SBC, Arduino, Raspberry Pi, PC, Mac... - Ulule") and seeking input and visibility on technical forums. However, if you’re promoting it on technical forums, the minimum expectation would be to answer technical questions (ideally documented on the Ulule site) to demonstrate that the project is well thought out.
