In this video, the speaker reviews various products from AliExpress, ranging from a VFD display to an ATX power supply breakout board. They provide details on the features and performance of each product and give recommendations on whether they are worth purchasing or not. The video also includes a sponsored segment for PVCase, a PV planning software. Overall, the speaker found several useful products on AliExpress and encourages the audience to stay tuned for future episodes.
Here are the key facts extracted from the provided text:
1. The speaker reviews products from AliExpress in a video series.
2. The first product discussed is a VFD (vacuum fluorescent display) similar in appearance to a common 16x2 LCD, but it is 23 times more expensive due to its different display technology.
3. VFDs can be used with the same Arduino code as LCDs but require more current.
4. VFDs offer superior contrast, wide-angle viewing, and better performance in low temperatures.
5. VFDs are still used today, especially in harsh environments.
6. The second product discussed is T-Splitters for cable connections, which claim to be faster and better than traditional wiring techniques.
7. The speaker disagrees and finds traditional wiring with Wago connectors faster.
8. Testing reveals that T-Splitters have higher resistance than Wago connectors, debunking one of their claims.
9. The third product is a solar panel multimeter for 78€, which is considered expensive.
10. The multimeter provides information about solar panels' parameters.
11. It can help determine the perfect position and angle for solar panels.
12. PVCase is mentioned as a sponsor, offering PV planning software.
13. The fourth product is a circuit board for charging lithium batteries with a USB port and 5V output.
14. The board can provide a stable output voltage up to 3.1A and has good efficiency.
15. It also has low quiescent current, making the battery last longer.
16. The fifth product is damaged screw extractor drill bits for 4€, but they didn't work as expected.
17. The sixth product is an ESP32 microcontroller development board with an LCD for 10€.
18. It comes pre-loaded with a demo sketch and is suitable for projects requiring a graphical user interface.
19. The seventh product is an ATX power supply breakout board for 3€, which can convert an ATX power supply into a lab bench power supply.
20. It offers multiple voltage rails and USB ports for devices.
21. It includes a random feature of checking if an infrared remote still works.
22. The speaker recommends several products found on AliExpress.
