I found an assembly instruction book for the Open ReVolt

Welll... So far, after about 10 hours of searching over the net, I don't still have a clue of where to start from to buy or build my Open ReVolt Controller. It looks like everything related to this project is pointing towards M. Paul Holmes and that he is no longer supporting the project. I got the original project files though. It includes the control board schematics in .pdf format which could be very useful if I ever succeed to get what I need to build the unit but it also includes files with the .sch and .pcb extensions. I tried to use Orcad to view the .pcb with no luck. Anyone knows what are the softwares that were used to generate these files? Maybe these are containing my missing link...

Do you still have these files? Would you be willing to share them?
Also, do we have a lead yet on the actual code to put on these things once we get them built?

I do still have some boards if you want to buy some

what Boards do you have??

 

[MattsAwesomeStuff]

I swear I dug the files out again and gave them to someone other than Remy this year...

Again, probably not a good solution. I haven't heard of anyone building an OpenReVolt in half a decade.

...and it's likely the components could have as much as a two year leadtime. Without even one key component, you have nothing.

Make your project dependent on a $6 part with a 2 year delivery time and it will wind up as salvage in the classifieds.

This is not something to dismiss. Have all of the parts in hand before you fabricate any board these days. Here's an update I got from a supplier on parts for one of my projects from this past Sunday, if you don't believe me:

Which ATTINY? digi-key.com has ATTINY841-SSU in stock right now if they are what you need or will work. They might have the other chip in stock as well.
Later floyd

"Right now" is the important caveat in that statement.

Design your schematic, board layout, send it to PCB fab...then find zero stock.

The whole methodology has been turned in its head to where it doesn't go on the schematic unless it's ordered. Which is fine for a handful of devices and boards.

Then you go back, redesign the schematic and firmware to use your '841.

Then you go back, redesign the schematic and firmware to use the next one that's in stock.

A documentation, support, and revision control nightmare.

Okay, so the next question... supposing we get all the parts and get the hardware assembled and it's glorious, does anyone have the code that needs to go on these to make them function?

Here’s a link to the files I have (If I find more files I’ll add them):

How many sets of boards do you have? Do you have both Logic and Power boards?

 

[CapCarCap]

I have 3 logic boards left and no power boards
