We talked to Alexis this afternoon about ground transmission, and the solution we will finally go with is a mixture of those proposed in yesterday’s post. We will use wires soldered to the main PCB, and fix the GND wire to the axis with a sleeve clamp. Here is a diagram to present it:
@RoseAce : Could you please give us a hand ?
How many ball bearings did you use for VCC transmission in your project ? Thanks in advance for your help 🙂
Happy New Year everyone, hope you enjoyed the holidays !!
Today we are going to talk about the latest trends of our hardware architecture.
New PCB disposition to drive the petals
We used to try to drive each LED with its own processor. However we could not manage to get every component to fit on the PCB petals. Moreover, the processors were underused as we barely needed half of their timer outputs. Therefore, further inside the Phyllo, we decided to add a layer with slightly bigger PCBs (let’s call them the petal controllers). They have a STM32F207VIT6 which can drive up to 10 LEDs.… Read more
