AliExpress

I'm almost sure it was sent from China and not Emirates. I think they are trying to trick Canada Post for the reasons you explained.
 
On a good AE note, I ordered 5 items at once, 3 were combined and got here in 10 days. The other 2 shipping were upgraded.
I didn't realize you can change the shipping options, different vendors may cost a bit more but full tracking may be much cheaper. AE is tricky!

This is the faked packet with fake tracking number, not the AE one on the website and the fake Emirates stuff. Who knows what the AE tracking was that showed it got to Canada about 6 weeks ago. I wonder if China has spoofing for the tracking number.

This is my project to use a PIC 16F877A to display sensor values on a little OLED screen. So far it has a PM2.5 & CO2 sensor using I2C. More coding to come. The Arduino at the edge is just to provide power.
 
I ordered 60 cc syringes (for watering the plants) 10 for $10 with shipping and they got here in 9 days. Got to enjoy AE while it lasts.
 
Aliexpress is a hit or miss IME, no delivery even after 2 months, then when I ask for refund, manager does request to wait another 30 days !!!
Did you escalate to AliExpress itself? In the past, they have actually sided with me and not the vendor. Now luckily, I've only been out a few dollars on the rare occasion. My larger purchases (for astronomy stuff) all went well. I would think long and hard about buying something over $150.00, say.

That's a decision of Aliexpress to wait for another 30 days ! In the past, if I asked for refund, let's say after 1 extra week, I got the refund immediately. Prefer Temu, prompt delivery, however need to order 35$ at least.

This reads a UV sensor. The red LED blinks every second. The green LED goes on when the UV index is 3 or over. Then I know to put my sunglasses on. I added a mini switch. When you push it, you have 4 seconds to check the UV, then it goes into a very low power state. Also I soldered 3 button batteries together for a more convenient power supply. The off current is very low so the batteries should last.
Problem: if it's bright, I can't see if the LED is on! So I changed the code so if UV3 is detected the MCU goes to sleep with the LED on. Then I can check the LED in the shade. Then I cover the sensor, press the button and the LED will go off to save battery power.
The experiment board is from @WillyCKH.
