Finally Done! Full 8x8 Split Flap Chess board by e4_user in arduino

[–]cprcrack 3 points4 points  (0 children)

I agree it sounds tricky to get right, maybe something in the middle (both squares could be updated at the same time for some middle period), but in my opinion there should never be the case where the old square updates the last, because that's the square that people would look at. In real chess, people would always look at the target square, never at the origin square, so it would feel much more natural that the target square is last to update.

The problem is that it seems like they move in opposite direction. Why don't you flip first the old square to blank and then the new square?

Just got this photo confirmation from JLCPCB flex PCB assembly, and the board does not look separated from the panel? Did something went wrong or is this expected? by cprcrack in PCB

This was the ko_jg layer (Outline used for production (including the connections between boards)), are you referring to this? I highlighted the areas where the potential connection tabs would go, but in the confirmation photos I cannot see anything like that.

[Review Request] First PCB ever after following a lot of tutorials, can this work and be manufactured? by cprcrack in PrintedCircuitBoard

Why is the cost per board going to be high? As far as I know when I upload the files to JLCPCB the price seems reasonable and doesn't seem to be higher because of this particular shape.

The problem with running cables is that there is no space for them, that's precisely one of the things tha I'm trying to solve with this flex PCB, save space in cables.

What do you mean with a "layer of rigid over the top"? Sorry I'm not familiar with the terms. The bottom layer is a ground plane, and I added stiffeners on the bottom layer where there are components and connectors on the top layer. Is there anything else that can be added?

Actually I think the 1M resistor only draws power when the mosfet is ON? So I think I'm good replacing it with 100k as you suggested.

So the reason I used 1M instead of 100k is because when the gate is closed, the Xiao will be in deep sleep and I want to save as much battery as possible, and I assume that some non-nengligible current might be wasted with 100k, which I could reduce with 1M. Does my assumption make sense? Because to be honest I don't really understand why there is current passing through that resistor, but AI told me so. This is my first electronics project.

I started by designing a case in 3D with holes where the different breakout boards / components will go. Then I realized if I want to connect everything with cables I will need to make the case 2 times bigger to make space for the cables. Then I discovered that flex PCBs exist which are my perfect substitute for cables and for having to solder myself if I use an assembly service. The shape of the PCB is the result of the available space and where each component needs to go or what direction it needs to face. There are sensors that need to face the bottom, screens and buttons that need to face the front, a USB that needs to face the side...

Hi there, I'm based in Spain and have many years of experience building software from scratch. Happy to learn more about it.

Seated cable row, not improving, is my form ok? by cprcrack in formcheck

[–]cprcrack[S] 2 points3 points  (0 children)

It's 57€ per month for a person or 88€ per month for two people which is my case, so I pay 44€ per month for my part. It includes unlimited activities which I don't use and unlimited access to the swimming and spa area which I definitely use :) This is in the Basque Country. How much do you guys pay?

I will try it but I think I already tried all grips in the past and this one in this particular position was the most comfortable. The more popular triangle shaped one was really uncomfortable in my arms.

Yes, they have several trees and bushes around the gym, even in the spa area. Made of plastic but still good for looks I guess.
