Witam! Chciałbym przedstawić wykonany prze zemnie VU metr. przeglądając różne konstrukcje na YT postanowiłem złożyć w większej wersji takowy audiowizualny gadżet. VU metr ma wysokość ok 376mm i średnice 150mm. Dyski (26szt) wykonane zostały na laserze z przeźroczystej pleksy 5mm. W celu uzyskania lepszego wizualnego efektu przeszlifowałem krawędzie. Każdy dysk jest oddzielony aluminiową podkładką 35mm x 16mm x 8mm. Podstawa i górny dekielek również wykonany z aluminium na obrabiarce CNC. Diody LED zastosowane w konstrukcji to taśmaWS2812b (74diody/m ), które są przyklejone do rdzenia całej wieży wykonanego z półwałka aluminium o średnicy 16mm. Całością steruje Andurino Nano, program zaczerpnięty został z podobnego projektu i przystosowany do obsługi 26 diod LED. Program obsługuje wyjście linowe, po odpowiedniej modyfikacji programu można przerobić na mikrofon. VU metr posiada 16 trybów wyświetlania w tym tryb automatyczny, które przełączamy wciskając przycisk. Całość zasilana z ładowarki od smartfona 5V 2A,

Efekt niesamowity, przyznam szczerze że jeszcze nie widziałem takiego UV Metru, i po obejrzeniu filmiku jestem pod ogromnym wrażeniem . Spokojnie mógłby posłużyć za oświetlenie na niejednej domówce. Niestety wydaje mi się, że opis jest niekompletny – brak kodu źródłowego…

Rozumiem że ów koszmarek o nazwie “kod” nie jest Twojego autorstwa – dobrze że to zaznaczyłeś bo miałby jedynkę :):):)

Szczególnie mnie zastanawia o co autorowi chodziło w tym fragmencie:

switch (buttonPushCounter){

case 1:
buttonPushCounter==1; {
All2(); // NORMAL

    Ale to nie jest poprawna składnia.
    Obstawiam, że chodzi o linijkę:
    buttonPushCounter == 1;
    Linijka ta jest zdecydowanie niepotrzebna. Klamry { } w tym wypadku też nie są potrzebne

czy na pewno przycisk jest dobrze podłączony ?
wsad generuje mi błędy i nie wiem o co chodzi z tą biblioteką

spróbuj z tego pliku, u mnie działa wszystko OK, może brakuje ci jakiejś biblioteki ?

Uporałem się z tym. Pousuwałem kilka rzeczy z opisów i zaktualizowałem biblioteki. Pytałem o FastLED bo nie rozumiałem tej linijki w raporcie błędów. Mam pytanie jeszcze o ten przycisk czy na pewno on powinien być między DO/RX a GND ?

Przycisk masz zdefiniowany w programie. Dokładnie tak ma być podpięty.

hetm4n byłbyś w stanie podesłać zwymiarowaną podstawę, półwałek, dekielek oraz dystanse? Czy mógłbyś też podesłać link do paska LED skąd zamawiałeś? Będę Ci niezmiernie wdzięczny jeśli udzielisz mi odpowiedzi na moje pytania. Dziękuję

Jeszcze raz dziękuje za fantastyczny projekt Wykonałem go dla mojego wnuka. Filip bo tak się nazywa mówi do swojego młodszego brata “Dlaczego tak krzyczysz wieża się na ciebie gniewa i jest cała czerwona”. Domontowałem moduł mikrofonu na przełączniku.
Pozdrawiam wszystkich serdecznie.

Witam,
Mi to jakoś słabo działa, z kondesatorem 1uF nic się nie dzieje, bez coś się tam zmienia ale z pewnością nie tak jak na video. Czy to działa przy 16 diodach (N_PIXELS poprawiłem na 16) ?
Odpowiedz
hetm4n Autor 22 kwietnia 2019, godz. 19:56

powinno działać nawet na 16, zresztą do próby możesz wklepać 26 i powinno migać , jak to masz dokładnie podłączone?

  dokładnie tak jak jest na schemacie, podłączam do wyjścia na słuchawki od laptopa. Migać migają ale nie ma sensownego efektu jak na wideo
