The current state of the EU's Cyber Resilience Act (CRA) will have severe and negative consequences for open source communities. Help us #FixTheCRA by making your voice heard. Learn more at linuxfoundation.eu/cyber-resilien… @LF_Europe @ep_industry

ThingSet + #ZephyrRTOS: Transport-Agnostic Device Connectivity Within 10 Minutes. Need to see it to believe it? Martin Jäger w/ @LibreSolar will present a live demo at #ZephyrDevSummit. Register to attend virtually and add this to your schedule: hubs.la/Q01Tqtrt0 @ZephyrIoT

The #opensource #BMS, created by @LibreSolar and funded by @EnAccessFdn can save you a significant amount of money. How much? Martin Jäger, Lead Developer, explains it all here. Get your hands on all the Open Source tools you need to get started here -> enaccess.org/battery-manage…

Prototypes of our new BMS C1 funded by @EnAccessFdn are currently being assembled at @fabulousstpauli. Really excited to power them up later today.

Can building your own #renewableenergy system really be as easy as assembling IKEA furniture? Yes! It’s all about open educational resources & taking an #opensource hardware approach. Learn more from this presentation by our partners at @LibreSolar: youtube.com/watch?v=G2cUZp…

Today is Open Hardware Summit time! Don't miss the talk by @RoboTinxs and Michel from Libre Solar team about "How to Enable Anyone to Build their Own Renewable Energy System". @ohsummit 2022.oshwa.org

"How to Enable Anyone to Build their Own Renewable Energy System” will be covered by our partners from @LibreSolar at the 2022 Open Hardware Summit. Join us to learn about the opportunities of our Battery Management System (BMS) project with @LibreSolar! 2022.oshwa.org

@dotunebiekuraju @kicad_pcb Looks great! We are also developing MPPT charge controllers (as Open Source Hardware) with KiCad, but most designs are still with v5. Just now switching to v6 for our next gen BMS. Check out libre.solar.

Made this charge controller with KiCad 6.0, it was a breeze compared with older versions. Thumbs up for the @kicad_pcb team. You rock!

We are happy to be elected as new board members of @fabcityhamburg. Together we will make huge steps towards locally produced and globally developed #OpenSource Hardware for everything.

We are applying for funding from @EnAccessFdn to develop a next gen #opensource and IoT-enabled 48V Battery Management System running @ZephyrIoT. Suitable for 2nd life, productive use and micro-grid applications! Leave your feedback here to make it happen: community.enaccess.org/t/open-source-…

On June 9 we will talk about using @ZephyrIoT for digitally controlled Solar Power Converters at #ZephyrDevSummit. Register now and get in contact with the amazing Zephyr community: github.com/zephyrproject-…

The deadline to register for the #ZephyrDevSummit is tomorrow! Check out Day 2 sessions from @AVSystemCom, Circuit Dojo (@jaredwolff)@intel @IntelSoftware @LaasCNRS @LegrandNA @LibreSolar @LinaroOrg @lpnplant @muni_cz @percepio & Teslabs Engineering: bit.ly/3fNRi6j #RTOS

Last week at the @LFE_Foundation Spring Summit, @LibreSolar presented the Open DC Grid Project w/ @jlgula1953 & talked about using @ZephyrIoT for power electronics. If you missed it - check out the slides: bit.ly/3gjPVgc #LFEnergySummit #ZephyrRTOS #opensource #RTOS

@JordoSilverman Yes, it was recorded. Will be published on YouTube soon, as far as I understood.

@LibreSolar Nice! Was it recorded so we can catch up?

Q&A session in the middle of the night :) We talked about how #opensource standards and hardware can help to accelerate access to clean energy in off-grid areas at #LFEnergySummit.

@_kate_stewart @ZephyrIoT We could only scratch the surface in this talk, so we are planning to dive deeper into Power Electronics Applications on upcoming Zephyr Developer Summit.

Ever want to be in 2 places at once? Wishing very much I could listen to sched.co/iKO9 live, but I have to give my talk at the same time. 🤩

We will present the Open DC Grid Project (open-dc-grid.org) together with @jlgula1953 and talk about using @ZephyrIoT for power electronics at @LFE_Foundation Spring Summit. Hope to see you there! sched.co/iKZh

Next gen 20A MPPT charge controllers just arrived and ready for testing. As usual, boards developed with @kicad_pcb and fully #opensource: github.com/LibreSolar/mpp…

Our #preprint is out: "Standardisation of practices in Open Source Hardware" arxiv.org/abs/2004.07143. In an amazing collaboration with #OpenHardware advocates @Du33Jerry @jenny_molloy and Martin Häuer! @GOSHCommunity @ShuttleworthFdn @DIN_Norm @openHWleaders @alfredoh1234

@uint8_t @jlgula1953 The people from @solar_cooling (Julian was also in the call) are developing DC fridges.

Keen to develop an open specification for 48V DC grids? Check out dc-grid.github.io and join tomorrow's kick-off meeting with @jlgula1953. Jan 14, 15:00 UTC (16:00 in Germany): freeconferencecall.com/wall/jlgula
