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.

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.

ニュージーランドまで1週間 私は使用を停止していますので、配達は数ヶ月かかると頻繁に到着しない。

All OK. Only 1 week to New Zealand. I have stoped using Aliexpress because delivery takes months and often never arrived.

これらのキットの2つは既に処理済みです。 成功制御のための最終的な機能を持つ非常に良いはんだ付け練習。 スポイラー: チップPX088Aの後ろのワイヤブリッジが、製品詳細の下の写真のように、私の誤動作につながり、分離されました。 しかし、これは良いデバッグ演習でした。🙂

Habe bereits zwei von diesen Bausätzen verarbeitet. Eine sehr gute Lötübung mit abschließender Funktion zur Erfolgskontrolle. Spoiler: Die Drahtbrücke hinter dem Chip PX088A, so wie auf dem Bild unter Produktdetail dargestellt führte bei mir zur Fehlfunktion und wurde getrennt. Aber auch dies war eine gute Übung zur Fehlersuche. 🙂
