Take over responsilibility for inverter development and support

Post by johu »

So, this is kind of a biggie for me. I want to step back from inverter development completely. So I would be happy to hand over
- Responsibility for stm32-sine and FOC firmware repository
- Responsibility for inverter-hardware, Tesla-Large-Drive-Unit and Tesla-Front-Drive-Unit repository
- Drafting of new releases, integrating PRs etc.
- Maintaining boards
- Optional: Selling boards
- Doing support on the forum
- Doing payed support

I will remain active in BMS, CCS and libopeninv development!

Whichever (group?) takes this over will have to set up a web shop or other distribution channel for the boards if so intended. Happy to leave them in the OI shop as stubs and link to the new source.

---
Reason: I think I've given this topic all I can and I no longer want to deal with blown Tesla inverters especially. I want to focus my resources more on the remaining projects.

For a bit of practise for the willing I will start ignoring inverter-related topics

I'll be the first to admit I absolutely do not have the knowledge to take over the firmware. But, I might be able to take on board distribution, at least for the US market*. Its something I've already thought about, but let me do some research over the next couple of weeks.

*given the state of geopolitics, it might be worth having different folks handle the US and EU.

Thanks for speaking up.

So, the inventory:
- West side EV already sells SDU and LDU kits
- A Californian citizen is offering to take over HW/SW development AND board distribution
- You also want to distribute boards

So in the US we have 3 (potential) distributors, in Europe none. Lets see how we can build up upon this.

In light if that, I would say go ahead with the person in California. I wouldn't be able to get something set up right now.

I will, however, make the following commitments to the community:
- I will do my best to get a store set up by the end of the year as an additional source for OI related boards.
- I am actively working on getting the education I need to start helping develop new boards - specifically to work on stuff that's only or primarily available in the North American market.

Would love to help with stuff like that where possible. Especially for racing applications, lowering the barriers and getting more conversions on track. What kind of education are you talking about?

I don't want to completely hijack this thread, but essentially, basic electronics design. I'm currently researching what I can find online, and considering some community college courses too. My engineering background is much more on the mechanical side of things.

Johu, do you want to hand over the wiki and forum administration as well?

If you do, I think it is well worth the time to create searchable backups that don't allow for adding information, but are online forever in the event of things going south. I have been part of communities where the handover of the forum went badly and the community died. These things happen, but the tragedy is the decade of accumulated knowledge that built up in the forum before the handover is now gone forever. If someone had just set up a cron job to export the forum data to a static site on github pages each week that knowledge would still be available.

Happy to help with that.

Just the inverter project.
This backup idea might still be worthwhile. Right now I just pull a complete file system and data base backup to a local raid array.

Hi guys,

I`m Karim the mention "Californian Citizen". I`ve been part of this community and following the amazing great projects here. i do HW design and developments for living and very passionate about the OI community. 2 complete projects running for more than 4 years based on OI work and Johannes's and Damien's best creations.

For this topic i torched based with Johannes and I`m ready to give hand right away on
- inverter-HW development/maintaining, LDU-HW and Front DU-HW.
-Marinating Boards current and future revs.
-Giving support both on OI and other non-conventual requests for the motioned items.
-Selling the Mentions items based of the US to both US and EU. "Web shop is in progress and could be up and running within 2 weeks"
-for the FW repo and managing PRs and releases I'm familiar and have managed my own custom firmware for my projects, but will be more of a partnership with another main POC for FW initially until we can see the workload.

Johannes, thanks again for creating the OI community and your efforts to continue supporting the future of those mentioned items. I would like to give you a hand or two helping as we discussed on our call.
Hammer, Duct tape, WD-40 that`s it :D
