    Η συσκευασία είναι χάλια, κάποια κομμάτια βγήκαν από την τσάντα, νομίζω ότι είναι όλα έτοιμα. Δεν υπάρχουν οδηγίες, θα συλλέξουμε τυχαία

    The laser Harp kit is very interesting. The side of the harp power connector is the switch that plays the selected built in melody. The other side has 3 leds that indicated the current melody and user selects them by presses of the button near these leds. When the built in melody is not playing, the laser beam the user interrupts by blocking with perhaps their finger play the note associated with that location. Note that the leds along the back light when the note is played giving a visual of the note used. Since the laser heads are adjustable focus, you experiment twisting brass lenses to make a fine dot. The alignment downward into the light sensors would best be done by powering on unit and use hot glue gun to fasten led when you holding by tweezers at the optimal angle for the center of light sensor. The 3d printed brace is not easy to adjust this way. You might substitute an old usb power cord in place of the smaller barrel power socket I don’t have adapter for. Then its easy to power the unit from a USB port for power only. It was tricky to solder the side arm that supports the lasers. It’s best to keep part flat on its back to the table when welding side rails.

    It was a fun project to put together. I used hot glue to keep the lasers focused on the receivers. One of the lasers was missing a wire, so I had to fix that. Another laser didn't work. The note that is associated with the missing laser works anyway. I guess it would depend on what kind of ambient lighting you have. I think there should have been 8 notes, so there would be an entire octave.

    It seems to me an interesting product, I still have to assemble it. Fast delivery.

    c'est intéressant à bricoler on bosse dessus

    Ωραίο να το χτίζεις, λίγο ασταθές, αλλά δουλεύει.

    Il prodotto arriva senza alcuno schema di montaggio, ma i valori sono riportati sulla serigrafia quindi assemblare tutta l'eettronica non presenta alcuna difficoltà. Spiace solo non riuscire ad avere informazioni sull'uso dei pin TX e RX comunque presenti sulla scheda Facile capire il funzionamento dei pulsanti P1 - seleziona una serie di melodie già pre-registrate P2 - Seleziona l'ottava, ne ha tre a disposizione a) non suona note contemporaneamente, quindi una sola nota per volta b) non è possibile cambiare ottava mentre sta suonando una nota il cambio dell'ottava è sequenziale, quindi 1-2-3-1-2-3 ecc ecc, quindi non è possibile ad esempio passare dall'ottava 1 alla 3 con una sola pressione di tasto e quindi neanche dalla 2 alla 1 o dalla 3 alla 2 Ripeto però non sono ancora riuscito a capire uso di TX e RX. Nel complesso: 1) Il PCB è di buona fattura anche 2) Centrare correttamente i laser sulle fotoresistenze non è cosa semplice anche perchè i PCB di tenuta sono veramente difficili da allineare Nel complesso per quel che costa valutazione più che soddisfacente
