Pretty decent solar panel but as it seems with all solar panels in similar price range it's nominal power is probably only possible if you take a rocket and measure it in the vicinity of the sun, just before it starts to melt. The rocket I think :P I joked a bit, but honestly - the specs looks like to be very optimistic. Haven't measured the effective power but it was not able to charge a simple 4000 mAh (with 5 Volts it means 20W, right(?)) battery pack when connected for multiple sunny days, positioning the panel correctly, disconnecting it before sunset, connecting it at sunrise. Will test it further to get better data, looks like I have to make a simple logging tool to be able to track charging possibilities... At the same time I need to check this in the summer, with much stronger sun... Nice pack with accessories. Am pretty sure that this can not charge a car battery without the rocket ( :D ), but I will be using the accessories for other purposes :D But - for this price I think it is worth the money - I will try to charge a smaller battery as it should probably work better.

Looking good, but one must be careful when re-connecting often. One of mine broken very fast and I needed to fix it with some soldering

As a beginner with electronics I was very happy to see this tiny option I could use for small proofs of concept and I gave it a try. These are my personal opinions; I was a bit dissapointed when I plugged in the usb cable and struggled with installing a driver. After reading a bit more on the subject - it looks like it is missing a bootloader and you need to use additional special hardware to program it (would be nice if they came preloaded with micronucleous bootloader, especially for a noob like me) - so there is no easy way for plug and play. Bought one cheap USB ISP programmer and tried to use it but it was too complicated to use and it looks like I managed to destroy the AVR (don't know how but the LED on it now stops being on when I connect it to Attiny85 and the driver installation for the AVR was a nightmare on Windows 10)). So I just gave up and bought the original Tiny AVR at the end and it worked like a charm (I did not have an Arduino UNO that can also be used for programming). Now I will actually rethink the micronucleous as it is so easy to use the AVR. I just wished I would bought a version with DIP-8 chip that I could just plug in to AVR and get rid of the cables but it works with cables also, so maybe next time. But on the end - for this price - I must just be happy and really study my options better next time.

Q: hi just want to check each packet comes with one or two speaker?

Preguntado por suriyagan sobre 2019-03-30 06:37:48

BiSiNo I ordered 3 items - as it is stated in the description that each item includes 2 speakers - and expected to get 6 speakers. I got 4 speakers (on the declaration it is stated 3 items (correctly). Do not know how it is possible :)
