Lost & Stranded: Can a Business Bridge the Gap for Those Without Essential Documents and Belongings?

Image
I chatted with Gemini and at some point I got this summary:

Repair of multi-cooker control board CFXB60-W-MS2-DP CFXB60-W-MS2\MS3-DP GX V2.0 CORSO with IC TS3F465D-HD from Sapir SP-1985-A5

I suspected that the integrated circuit TS3F465D-HD is broken. But I was wrong.

Banks and bank-like fintech companies do not understand different address formats, especially one of the address schemes used in Bulgaria

"All Wise debit cards are valid for 3 years." - Wise.com ; Update: it's 5 years, not 3

I asked them: "I can't find where on your website is specified for how long is valid the debit card (after how many years will be the expire date)." The answer: Thanks for getting in touch! All Wise debit cards are valid for 3 years. We’ll let you know 2 months before your card expires, so you can get a new card by clicking on Order a new one. This way we won’t charge you a replacement fee. If you choose the Replace card option instead, you’ll be asked to pay a fee. If you want to replace your expiring card before the 2 month notification is sent, we can’t refund the fees. Let us know if you have any other questions. We're happy to help. Update: after I ordered a card I noticed that the card is valid for 5 years, not 3. (May 2022) My article about Wise in Bulgarian: Подводни камъни при ползването на Wise.com през 2021-2022 година

UX issues when signing up to Wise.com

Image
  The problem is "First name(s)" does not sound right for many users. Many will not notice it and will write their first name without realizing that they should also write their middle name or surname. There should be another field for the middle names and surnames. This may affect payments, because some banks and payment institutions do not allow payments with account holder names not matching 100%. After Wise accepted my passport they did not notice that the middle name is missing. And now I am waiting for them to correct this mistake. I can't do it because It's not possible to add a middle name:

The backlight of MOTOROLA MOTO E6S does not seem to use PWM for the backlight

Image
I tested it with a photodiode connected to the microphone input of the sound card.  When I position the photodiode towards the phone's LCD dispaly I do not hear signs of PWM. When I position the photodiode towards my LCD monitor Acer S222HQL Abid I hear about 1kHz beep (this is to confirm that my setup is correct). Here is a photo of MOTOROLA MOTO E6S: I am posting this MOTOROLA MOTO E6S image because this way my article will be better indexed by search engines. And may help users searching information about MOTOROLA MOTO E6S (if PWM is used for the backlight or not). Another photo of moto e6s: I am using these devices (stylus pens) instead of my fingers because I don't want fingerprints and dirt on the display:

HP1740 not working correctly, problem with colours and flickering

Image
Most likely the problem is with RTD2523. The board is BENQ 48.L1G01.A02. The power supply is providing 4.97V and 3.28V in standby mode and 4.93 and 3.26V in "on" mode. I checked and the chip should work with voltage greater than 3V, so 3.26V should be fine. Now I have RTD2523, will write later what happened.
