                                                  The problem is that your electrician messed up when wiring up your switch. According to electrical code, you are supposed to switch off the Hot or Live wire. For a LED bulb to do this, you are switching off the Neutral.

                                                        hi mehdi

                                                        i was watching one of your videos and it reminded me of an electronics conundrum that i had since i was a kid and have never figured it out (because no one so far was able to explain it for me)

                                                        i found out at a young age that there are a lot of toys that are battery operated that you can run by simple removing the battery and connecting it to a DC Adapter directly (albeit by cutting of the jack of the adapter and then replacing it with bulldog clips so you can easily clip them to the toys battery contacts)

                                                        but as i said, it works for a lot but not all of them. in my teens i tried to do the same to some Walkmans and cameras and it did not work. why is that? i know its not about voltages for i have this DC adapter that has variable DC output from 3-12V and i know i have chosen the correct voltage. I also made sure that the polarities are correct but still, to no avail.

                                                        it will be good to have you teach us what do we need to know to make this work. can we run all DC battery devices with a DC adapter if we want to? Thanks for your time and more power.

I really like the way you divulgate the science of electricity :-) I have a question I can not find an understandable answer...Could you quantify how much energy you can extract from a piezo disc, in relation from the energy you use to compress it? Thanks and best regards. Andrea.
