Customer:
I have several questions about your products.
- LED strip:
https://soldered.com/hr/proizvod/adresabilna-rgb-led-traka-ws2812b-30led-m-5v-ip20/
Can this strip be used for projects not involving programming? Specifically, is it possible to cut this strip as needed and use it by simply connecting a female USB connector to its ends to supply the necessary power for operation? If so, do you have such connectors in your offer - with just two wires, “+” and “-”, right?
Also (I’m aware this is somewhat unusual), do these LEDs on the strip get too hot - for example, if placed over fabric or similar materials - with potential fire risk (we’re doing various small projects)?

Some time ago I contacted one of your colleagues about buzzers for electronic projects. However, despite their best efforts, we couldn’t find a mutually acceptable solution. I need a buzzer that would work on DC voltage of 5V (preferably) or 12V or 24V - not one used in programming like Arduino where an AC signal is applied and it buzzes. I need a powerful buzzer that works on the mentioned DC voltage by being activated when a button is pressed or when DC current flows through it. Your colleague offered your buzzers and I bought them, but they don’t work as I expected (I think it was a passive buzzer). I’m not blaming your colleague, please don’t misunderstand me, but when I connect these buzzers in a circuit and apply current through them, for example via a button, I only hear a small, weak “tick” (something like the very soft sound when a computer keyboard key is pressed). That doesn’t work for me. Do you have the product I need?

Can I ask: do you know of any justified reason why you don’t have technical support via phone line - verbally, rather than exclusively through email?

Imam nekoliko pitanja vezano za vaše proizvode. 1. Led traka: https://soldered.com/hr/proizvod/adresabilna-rgb-led-traka-ws2812b-30led-m-5v-ip20/?srsltid=AfmBOood5WHnGRYQBY-jxxl3pZ3oh0kJpX4m2bmpTmeampo7VHF7JL2x Je li se ova traka može koristiti za projekte koji nisu povezani s programiranjem? Naime, je li moguće ovu traku rezati po želji i koristiti na način samo da se na njene krajeve spaja ženski USB priključak i tako kao da punimo mobitel dovesti na nju to potrebno napajanje za rad? Usput (svjestan sam da je malo neobično pitanje), griju li se previše ove LED-ice na traki – npr, ukoliko idu preko neke tkanine (i/ili slično) ili ne nalaze blizu iste – potencijalna mogućnost zapaljenja (radimo različite projektiće)? 2. Prije nekog vremena sam bio kontaktirao nekog od vaših kolega vezano za zujalice u elektroničkim projektićima. Međutim, unatoč silnom trudu vašeg ljubaznog kolege nismo uspjeli pronaći neko naše zajedničko prihvatljivo rješenje. Naime, meni treba zujalica (“buzzer”) koja bi radila na DC naponu od 5 V (najbolje) ili 12 V ili 24 V, dakle: ne ona koja bi se koristila u programiranju, recimo za Arduino pa na nju dolazi AC signal i onda ona zuji. Dakle, potrebna mi je snažna zujalica koja bi radila na spomenutom DC naponu na način da se ista uključi pritiskom na tipkalo ili kada kroz nju teče istosmjerna struja. Vaš kolegi mi je nudio vaše zujalice te sam iste kupio, ali one ne rade kako sam ja očekivao (mislim da je bio “pasivni buzzer”). Nipošto ne krivim vašeg kolegu, nemojte me krivo razumjeti, ali evo – te zujalice kada ih uključim u strujni krug te na njih pustim strujom, npr. preko tipkala, onda se samo čuje neki mali, slabi “tik” (nešto slično kao jako lagani zvuk kada se pritisne neka tipka na tipkovnici računala). Ali, to meni ne odgovara, napisao sam vam što mi treba. Imate li takav proizvod što meni treba? 3. Smijem li znati odgovor na pitanje, znate li ga uopće: postoji li neki opravdani razlog da vi nemate tehničku podršku putem mobilne linije – usmeno, a ne ovako isključivo putem elektroničkog dopisa? (To vam je jedna moja velika ali i jedina zamjerka za vašu tvrtku, odnosno u kojoj vi radite).
