Raspberry Pi Hackers

@rock12johnson What are you talking about please? What is Cash App?

The Open Hardware Summit is the annual conference organized by the Open Source Hardware Association a 501(c)(3) not for profit charity. It is the world’s first comprehensive conference on open hardware; a venue and community in which we discuss and draw attention to the rapidly growing Open Source Hardware movement.

The Open Hardware Summit was founded in 2010 by Alicia Gibb and Ayah Bdeir with support from Peter Semmelhack and Bug Labs in its founding years. Read more about the history of the organization and feel free to contact us with any questions.

From 2013-2018 the Open Hardware Summit was chaired by Addie Wagenknecht. In 2020, we welcomed Rolly Seth as chair, and the Summit was held virtually in light of the Covid-19 pandemic. For the 2021 Summit, which is also being conducted virtually, our chair is libi rose striegl. The Summit chair also serves as a board member.

Tickets are available and for sale on Eventbrite. Standard and Backer tickets must be purchased by March 25 to help ensure your goodie bag arrives before the summit.

Did anyone use Arduino Portenta H7 with Arduino IOT Cloud? It is listed on IOT Cloud Page but it's not supporting!

When I was trying to connect the board with the, it says The device found is not compatible

But it's listed in the supporting board page.

also mentioned in the portenta page .

@milanvarghese No, the battery comes into the play only if there is no power from the solar cell. It's like inverters in our home. They activate only if main power is gone, rest of the time they keep charging. similarly here the direct power will be coming from the solar cell, only if the solar cell can't produce enough voltage battery comes into the loop and starts providing voltage to our circuit.

@milanvarghese Basically you have cited the solution to your question. yes, you can run the Arduino microcontroller from a solar panel with some protection circuitry in between. There are many tutorials and blogs out there. You can start with something as following.

. solved right?

Hi all,

I recently came across this post where they have shown photos printed on PCB in high resolution. I would like to know how to add this kind of photos to the silkscreen layers of the PCB in Eagle/Altium.

Adding such kind of photos will be attractive for beginners and also can be used for educational purposes too.
Please let me know in case anybody knows.
