However there is still flickering with a 5v led bulb - any way to stop it?
Also, the mod does not appear to be exactly 'UL' tested and approved, as is many hacks! Thoughts about components left hanging?!
Happy back at ya!
A "5v LED bulb" ?
What is that? What is the real or equivalent wattage of the bulb?
I have not tried this hack as an extra resistor (R6 I think) is being cut. But I think the Lamp Module has the same "what is the output doing" sensing as the Appliance Module, and this is different from the "Local Sense" feature discussed in the video. If your LED bulb in question is very low "wattage" i.e. a nightlight or similar. Then I doubt the flicker can be stopped with out using a shunting resistor across the light. If you are concerned abut the "flying leads" of the disabled components in the module, then you likely won't be trying to solder a resistor across the LED socket. (definitely not UL approved).
You might try one of the newer "filament" style LED bulbs. These seem to have a much simpler resistive power supply which may only glow, but not flicker.
As far as the flying leads: The leads are fairly stiff, but even so, pose a slight risk of touching other components. The R3 lead is close to the triac heat sink, the R6 and D10 are both close to the edge of the board so could be pushed against other components in a sloppy re-assembly of the case.
When you modify an existing design of any device (especially a line operated device) you have to take a risk. Obviously the "hack" is to cause the device to operate in some manner not intended in the original design.
Personally, I would likely unsolder the components. But if you do not solder, an alternative would be to use bits of electrical tape to isolate the leads, or cut both ends of the component, which risks damaging the adjacent components.
