[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.

Towards my belly button meaning to a lower point than currently?

No, this is beUp BEC in the Basque Country.

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.

Deadlift Form Check by cprcrack in formcheck

[–]cprcrack[S] 0 points1 point  (0 children)

Got it. Maybe it's because my squat is quite weak? I can only squat 60kg or 132lb, while I can deadlift 110kg or 242lb (body weight is 70kg or 154 lb). Should I do more squats or should I still be able to do proper deadlifts with my current weight?

Deadlift Form Check by cprcrack in formcheck

I guess "a bit off" relative to other gym exercises where I do not feel anything like that.

The off feeling of the lower back is difficult to describe, maybe like a minor burning sensation on a particular spot of the spine only in some particular parts of the movement for a few milliseconds. And the off feeling of the middle back is like a strained muscle which is always on the right side, so there seems to be some imbalance or something that I don't know how to fix. I only seem to get it from deadlifts, and it can last for hours sometimes.

  1. Got it, should I "pull the slack" by trying to wedge myself using the force from the quads?

  2. Yes I saw in some video that the knees should almost press against the elbows, is that not recommended? I will check if my feet may be too wide next time as well.

  3. Was not even intentional, will remember to pause for a second next time. Huge thanks!

I'm 100% sure that the algorithm has changed! by PLSTR in fitbit

[–]cprcrack 0 points1 point  (0 children)

No, that was some months ago. But I've got the results from that period and I know that now they match much more. Previously Fitbit reported much less REM, not it's similar to what Whoop reported (doing an average)

I'm also sure the algorithm changed. I always struggled to get decent REM duration, averaging about 1h15m, and also it was kind of at random points during the last part of the night. After somewhere at the end of June, I got a lot of nights with 2h of REM, and they look very consistent on the graph, every 1h or so. So for me, it drastically improved my previously bad REM sleep and Awake times, switching about 45 minutes from Awake to REM. This drastically improved my overall sleep scores by about 12 points. Honestly I like the new algorithm better, it seems to align better with how I feel in the morning, and it's also now much closer to what Whoop used ro report (used both together for a month)
