|OpenRPN Prototyping In Progress|
Message #1 Posted by Hugh Evans on 18 Oct 2011, 5:06 p.m.
I will post pictures as the process goes forward, but hardware development is in full swing. Lead time is a couple of weeks for some of the parts, like deep drawn aluminum enclosures. I am working with several electronic design companies, but I really wish someone from this community would help with this instead.
The plan is to make a motherboard that can be used in any model. it will be built using SODIMM form factor. The planned CPU is ARM Cortex M3 (low power and a good enough display driver we could run a touchscreen!) running 16MB to 128MB PSRAM and as much flash as reasonable, a micro MMC slot will allow for expansion.
I'm waiting to hear back from e-ink regarding a custom display.
Since people who volunteered rapid prototyping seem to have vanished, there is a decision to make. If anyone has CNC, injection molding equipment (or mold design experience) can mill metal/other materials, rapid prototyping, etc. Please contact me. Otherwise, I can have many of the parts fabricated through emachineshop, but it will require larger runs to be feasible.
Building a hardware platform is priority number 1, if anyone is interested in partnering with me to help with financing it would be greatly appreciated. This will be a profitable venture.
I feel like I'm almost going at this alone and wish more of you would stop by openrpn.org to interact. This is not vaporware. I'm proud of the fact that I'm not afraid to try something and strike out. Last time we got a lot of useful code. I was also a less than wealthy Mechanical Engineering student when this project first started. Now I'm in a much better position to make this happen, but I would still appreciate some help (I'm sure Pauli wouldn't mind not being the lone programmer!)
As a side note: Can we please put the past behind us? For the most part OpenRPN is not the same project it once was. Effectively, this project might as well be two weeks old. So the comments of "vaporware" are uncalled for. OpenRPN is for the people in this community and other like minded individuals. Once the hardware is ready I plan to put it up for sale so people can start tinkering. The *fix core will make programming and creating new commands/menus simple. We have a lot to look forward to. I consider what we are doing to be the first calculator to advance to the 21st century. Give us a chance-- you won't be disappointed and you can help define the calculators of your dreams.
Thanks for taking the time to read this, I hope to see you on the forums at OpenRPN soon. I live near Columbus, OH... If anyone in the project is halfway near, perhaps we can meet up.
