Some good ideas for future projects

摘要

I built the Silicon Chip Remote Control Automatic Lamp Dimmer (July 2005; siliconchip.com.au/Article/ 3116), and it is still in (occasional) use today. The only thing I had to do with it was to replace the 220nF 250VAC Class X2 capacitor recently, as its measured capacity had dropped to 170nF.
