    Portable WiFi Analyzer

    This looks awesome, I install CCTV and alarms some of which use wifi most of which use Ethernet so I have been toying with the idea of having a go at something like this myself but which would also identify the current subnet, gateway and items on the network, test internet connectivity and speed and which could also act as a wifi hotspot for setting up wifi cameras without needing cablesSo this could be a solid basis for me to work from if I ever manage to learn enough about these microcontroller doodads to have a go at it.Cheers for posting it :)

    Build Your Own Electric Car!

    What an awesome project and it shows well what "could" be achieved on a relatively tight budgetI did wonder though, as a possible future "upgrade" would you perhaps fit a motorbike engine into the space left in the engine compartment? That could then be an emergency charge system or even top up the system when driving like some modern hybrids doThis might also have been able to create enough vacuum for power assisted front brakes too and with having so many batteries you would have the option of lowering the fuel used by such an engine by adding brown gas tanks to enrich the airIf you stick with it you could also keep an eye out for a scrapped proper battery car which use Li-ion batteries and get the packs out of that or as I have seen some people do on YT, build you...

    Sky Hub SR101 Modification Fix

    Does anyone know if theres a way to use this and change settings (subnet etc) without a broadband connection as it having a built in PSU is handy for onsite testingBut if I access the routers web page it just tells me there is no broadband connection and to contact sky with no apparent way to get into the settings

  • Extend Defective Fluorescent Tube-Light Life

    As you are modding the light anyway the 200ohm/8watt resistor could be mounted inside the fitting connected across the wires that go to the socket for that end of the tubeThe casing could then be used as a heatsink for it if a heatsink pad was used or a bolt on style resistor, a switch could even be added to remove the resistor from the circuit when that tube dies and a new one is insertedAlternatively a similar value inductor to the one in the tube itself could be added so that the heat aspect is partially removed also with a switch to remove it from the circuit if a new tube is later installedThat way the tubes themselves wouldn't need any modification as the mods would be inside the fitting itself

    Firstly I feel sorry for you if you think it would take time to have such thoughts. For you it might, but for the rest of us we tend to look at things and ideas instantaneously spring to mindNo time other than looking at the "thing" is required, or any longer than it takes to skim read a descriptionAbout the exact time you spent in fact....Hypocrite much?And why would it be a one off thing? If someone was keen on being green and environmentally responsible they WOULD try to do this with each bulb that brokeSo it would be worth spending the time to do it in a way that would last and be easy to reverse once a half dead tube dies completely, especially considering the chemicals and energy required to make them as getting an extra 30% per tube would equate to 30% fewer being made ...

    Arduino Data Glasses For My Multimeter

    Looks like an awesome project but as a minor side node, about two decades ago (seriously) a company called Quorum sold a pair of glasses that displayed a video image in each lense from any video source (it was composite input I believe) which I thought would really take off and might have done away with large screen TVs eventually as each person would be able to watch any channel they wished on their own pair with earbuds for sound Instead they just seemed to fizzle and vanish despite not being "that" expensive at the time as I recallSo if you ever wanted to explore a V2 of this you could perhaps look into how they accomplished that as I am fairly sure they were no bigger than a normal pair of specs and although the image filled the lense you couldn't see it when you focused y...

    I think the ones I am thinking of also made a similar claim but that's obviously just a relative thing though. After all a 24 inch monitor a meter a way will "appear" to be the same size as a 50" 5-10 metres awaySo the picture "should" appear huge due to the close proximityI didn't buy them at the time as I have a squint/lazy eye so things like that just don't work for me generally and it was too much to spend on something that might not work without a proper pair of peepers lol :)

    Sonos-like Wireless Multiroom Sound System

    As I said, I always regretting not being able to devote the time to learning the skills necessary to have a crack at it myself. And as time rolled by I just assumed someone else would be bound to think of it and do it before I could get to the level of knowledge needed so "why bother" sort of thing lolBut ironically I have a book of ideas out of which only 3 (from 27) have actually appeared in the market place as far as I am aware, So looking back I could really kick myself lol :)But luckily I'm not nearly nimble enough to be able to now haha :)

    If you wanted to get really clever you could set up some kind of proximity detection in each speaker although the method and frequency would probably need a lot of thought, so that as you move around the room it tracks how far you are from each speaker and alters the balance accordingly so you always have the perfect stereo image even if youre moving round a large roomIts an idea I had in my 20s to work with surround sound after watching a friend and audiophile use 4 tape measures to place his "listening chair" before turning on his ridiculously overpriced seperates hifi but I've never had the time to learn anything like microcontrollers or even analogue radio signal conversion to an extent sufficient to try and put this into practice. So when I saw this project I thought I wo...

So when I saw this project I thought I would suggest it as its remained at the back of my mind for over 3 decades now so it would be awesome if someone could actually do it

    What I have always thought would be a neat feature with this type of system is if it used a GPS or some form of proximity detector, even a PIR at a push to make the sound follow you rather than being on everywhere, even in empty roomsNot sure if that would be possible with this system, but if it would maybe that could be something you add later and then share?

  • Privacy monitor hacked from an old LCD Monitor

    If that doesn't work then try a hair drier to warm it up. Most commercial glues become tacky again if heated allowing the film to be peeled off far more easily when warm than they are at room temperature
