DIY CD4060 SMD Music LED Light Kit Electronic Experimental Training Teaching
A part of the review has been auto-translated.
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.
All OK. Only 1 week to New Zealand. I have stoped using Aliexpress because delivery takes months and often never arrived.
Good
Like describe
Have already processed two of these kits. A very good soldering exercise with final function for success control. Spoiler: The wire bridge behind the chip PX088A, as shown on the picture under product detail led to my malfunction and was separated. But this was also a good debugging exercise. 🙂
Recebido, completo OK
good product
