Touch lamp circuit for posterity....

[Guineafowl]

As part of troubleshooting this circuit I drew a full schematic, only to find near the end that the blob chip was blown - the crack was hiding behind a capacitor. Anyway, since I went to the bother, I thought I'd post the schematic here in case it helps anyone else...

I think the IC is a TT6061.

Might be useful to someone some day. I was almost glad the touch board was blown - I wasn't too keen on the board always being active and waiting for a touch. R1 would get quite warm even when the lamp was off.

A bit like those socket outlets with permanently-wired USB supplies. Not my cup of tea.

The lamp has been reincarnated as a normal lamp, with proper earthing and an inline switch.

That's interesting. I have several table lamps to which I've added touch sensor modules . Local Ace hardware store carries one that fits nicely in the base. Great for when I'm stumbling around in the dark.

Ahh well - did not Jimmy Buffet say 'if we weren't all different we'd all be the same ?
