Customer Reviews, including Product Star Ratings, help customers to learn more about the product and decide whether it is the right product for them.
To calculate the overall star rating and percentage breakdown by star, we don’t use a simple average. Instead, our system considers things like how recent a review is and if the reviewer bought the item on Amazon. It also analyses reviews to verify trustworthiness.
I am not an electrical engineer, i was told the remote I had may have stopped working because of the diode, the light at the front of the remote that sends the signal, in this case to an amplifier. I was able to solder a new one in place and it worked. very cheap repair as a new remote, which I couldn't find, would have cost around £70. The only reason I have not given it a 5 star review is that there were 40 items, 20 senders + 20 receivers, I only used one sender and couldn't buy less. seems like a waste to me. I must admit it was trial and error for the item, which worked first time, as i couldn't get the manufacturer to confirm the exact item I needed. Please don't contact me for advice as I will not be able to help.
I used these to build a TV-B-Gone device, and they work quite well! Only issue is that the range of the IR emission is a bit limited which can make it difficult to use, but overall, great product!

Los Leds emisores de IR los he usado para hacerme un head tracking para opentrack. He tenido que lijar las cabezas de los leds para dejarlos planos y aumentar su ángulo de emisión. Funcionan muy bien. No le doy 5 estrellas porque no indican a cuánta corriente deben funcionar. Yo he supuesto que son de 50mA.
