DIY NE555 Kit de ensino de órgão eletrônico

I had a good time putting this electronic organ kit together. Even though there were no instructions included, the circuit board had all the information needed to assemble the kit. The only information I had to look for was the voltage needed to power the organ. It needs 3 to 9 volts. I tried powering it with both three volts and nine volts. The speaker is louder when powered by nine volts. The tuning of the organ is only approximately in tune, but it's still fun. The momentary switches used are nice quality.
A nice easy kit with good quality components and board. Soldering was quite easy with good spacing. Very easy to follow the board component locations as there were no included instruction but really you don't need any. The top three notes are slightly out of tune but for the price what do you want? You aren't going to be playing any recitals on it, it's just a bit of fun and soldering practice. I would recommend as a very early starter kit due to the ease of construction but because it gives a satisfying result as well. You will need to supply your own power source but this is easily done with a 9v battery and a couple of wires. If nothing else it is wort the outlay for some spares.
Conjunto agradável, fácil de montar, porque a colocação dos componentes é impressa no pcb. Você precisa saber o código de cor dos resistores, ou um Ohmmeter :-) Ele funciona bem com 5V. A escala de som é ok, mesmo não muito bem sintonizada. Seria um bom projeto mudar os resistências, até que a escala corresponda melhor!
Item received on time and as specified in description.
good
A very easy to solder kit, my son (8 y/o) took less than an hour to setup. The sound is not comparable with computer generated tone but still a good experimental project.
Mais do que soldagem. bom preço
OK but it is impossible to play on it. Sounds do not go well, very out of tune
fonctionne très bien facile a monter
Very funny, it works perfectly.
