SUMMARY

The discussion centers on troubleshooting a touch lamp circuit, specifically identifying a blown TT6061 integrated circuit (IC) hidden behind a capacitor. The user shared a schematic of the circuit for future reference, highlighting the issue of the resistor R1 overheating even when the lamp was off. The lamp was ultimately modified into a standard lamp with proper earthing and an inline switch, demonstrating a practical solution to the initial problem.

PREREQUISITES
  • Understanding of basic electronic components, including capacitors and resistors.
  • Familiarity with integrated circuits, specifically the TT6061 model.
  • Knowledge of circuit schematics and troubleshooting techniques.
  • Experience with lamp modifications and safety standards for electrical devices.
NEXT STEPS
  • Research the TT6061 integrated circuit specifications and applications.
  • Explore circuit design principles for touch-sensitive lamps.
  • Learn about proper earthing techniques for electrical devices.
  • Investigate alternative touch sensor modules available for lamp modifications.
USEFUL FOR

Electronics enthusiasts, hobbyists modifying lamps, and individuals troubleshooting touch-sensitive circuits will benefit from this discussion.

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 ?
