This project was enjoyable to build but it didn't function properly on completion. The first issue is that the circuit board power trace connects to both throws of the switch. This means that the switch is constantly turned on. To fix this cut the trace between the two outter pins of the switch. See picture below. The second problem that was encountered was that all the lights lit and there was no speed control. This was fixed by adding (2) 100 nF decoupling capacitors. One for the CD4060 and one for the Music circuit. Connect them between the Vcc and the Ground on each device. See picture below. This solved the oscillation problem and allowed control of the lights. The final problem was not resolved as the music chip only played one continuous note. It didn't matter much as the price was right and I had fun putting it together and trouble shooting the problems.
muito bem feito funcionou direitinho como nu anuncio bom de montar qualquer um monta
When first assembled the sound was badly garbled and for the most pat the tune was not distinguishable. If you want it to work better cut the trace indicated in the picture and install a 1K resistor across the cut.
great!!! thank you.
Todo bien. Sólo 1 semana a Nueva Zelanda. He dejado de usar Aliexpress porque la entrega tarda meses y a menudo nunca llegó.
Bien
Como describir
Ya he procesado dos de estos kits. Un muy buen ejercicio de soldadura con función final para el control del éxito. Spoiler: El puente de alambre detrás del chip PX088A, como se muestra en la imagen bajo detalle del producto llevó a mi mal funcionamiento y fue separado. Pero también fue un buen ejercicio de depuración. 🙂
Recebido, completo OK
good product
