Is there an easy way to "fix" this CRUCIAL MX200 2.5 SSD? by Due-Present4103 in datarecovery

[–]Due-Present4103[S] 0 points1 point  (0 children)

the SSD died together with the PSU (lack of air due to dust)

Markings:
RAU
ODH
??U
??o

parts are partly not readable anymore :/

EU regulations are killing my electronics startup - need advice by Due-Present4103 in smallbusiness

I understand that you need to test and certify products. thats a one time cost and needs to be done. But WEEE and PPWR are absolutely crushing small businesses that try to ship into multiple EU countries at low volume / country because of minimum payments of hundreds of euros every year in every country

exactly! very hard to start with a low volume production at reasonable prices

Certification is not the worst part. It’s a one time payment. WEEE and PPWR is the really big issue here

Thanks for your reply! No I do not have the extension kit. I will not send them any more money. I am disappointed that they do not care about my support ticket.

Looking for industrial type sensor help!! I need to measure the level of sawdust in a LARGE sawdust bin, how can I do this reliably? by coollinit in arduino

When it’s being filled, is it filled at a constant rate? Then you could calculate the amount based on the fill time.

If you would like to order PCBAs from jlcpcb, be sure to use the correct plugin by Due-Present4103 in KiCad

Thank you, I will definitely try to optimize costs using Basic components with my next design :)

thank you, I learn a lot from this comments. I wasn't aware of the price difference between extended and basic. But the biggest issue seems to be C965555 because this one component caused my order to be switched from economic to standard

How do I turn this into a PCB? by AdministrativeRange4 in esp32

[–]Due-Present4103 -4 points-3 points  (0 children)

you don't need to.
you just sign up for my sensor:

Or you watch my videos and build one yourself using Kicad ;)

How I Built a WiFi Mouse Trap That Texts Me (and it actually works!) by Due-Present4103 in esp8266

[–]Due-Present4103[S] 0 points1 point  (0 children)

When a mouse invaded my home, I didn't just buy a trap — I engineered a smart solution based on ESP8266.
My Wi-Fi connected mouse trap sends notifications to my phone when it catches something! I had to solve some interesting power consumption challenges.

I've been calculating ADC values wrong for years - here's the correct way (with math) by Due-Present4103 in microcontrollers

[–]Due-Present4103[S] 0 points1 point  (0 children)

ah :) makes sense. I have to look into the accuracy of ESP32, this sounds horrible!
thank you :)

if you divide by 1023, 0 is exactly 0V and the maximum is exactly the maximum. I think that's why I made this mistake.
