Q: It looks as though there is an ESP32 chip on board. Can you confirm that this will have WiFi and Bluetooth connectivity?

MennoB There is alternative firmware available that unlocks this functionality.

The colours are hard to see because of the green PCB. Try to leave the leads a bit longer than the manual (not included, see site) recommends, so you can fold the LED's flat on the surface of the PCB. My kit came with only nine LED's, luckily I had a few in my part bin. Whilst being an experienced solderer (0603 SMD by hand), I found the LED's hard to solder on: tiny pads that required my 0,5 mm solder and extra flux to solder.

Arrived in less than two weeks. It has two female SMA-connectors, make sure you have the proper connectors for your dongle. Even though mine is now provisionally connected to my RTL-SDR with a Dupont-connector and crocodile clips, I already am more than doubling my range, from 100 km to 250 km. Quite impressive.

Quite impressive, so much functionality for so little money. I built it in an old subwoofer with an extra speaker for the high frequencies. Unsoldered the IR-receiver, soldered wires on and soldered those to the board. The receiver can now "look" outside through s small hole in the case. Overall sound quality reasonable, though there is some flutter audible when there are pauses in the music. Might be par for the course with Bluetooth though, my Bluetooth headphones suffer from the same problem.

Attention: of this kit only 1N5817 and 1N5822 are Schottky diodes. The description does not make this very clear.

Ordered a second one after on the first one the thermocouple wire broke off. So be careful not to bend this wire too much.

Q: Can I Connect two LED Strip 5050 (24W) & 5630 (30W) in parallel with this?

perguntado por Mohit Abhishek sobre 2019-10-26 03:16:56

MennoB No, 2 x 24 + 30 = 78W. This PSU can supply 12 V x 5 A = 60 W, so that is not enough. You can power the two 5050's, or one 5050 and the 5630, but that is already close to the specified maximum power. @mikeb1970: It's a rule of thumb to leave some margin. As as engineer, you should have heard of that.
