    Computer keyboard hazards?

    No particular hazards, just insulate it and you'll be fine.. Compact keyboards with a more normal layout are quite pricy, I agree.

    VESA Fixings & Samung TV

    Sort of. On the other hand: So they went a tad overkill with the bolt size.. but considering the quality of brackets people use, and their limited ability to apply sense when fitting them, M8 is probably a better choice anyway. And only very slightly non-standard. To be fair, I don't think...

    Computer keyboard hazards?

    Why would you do that.. arurgh. Can I interest you in just buying a keyboard without a numpad, if it's so 'useless'?

    Computer keyboard hazards?

    It's an isolated, 5V, current limited circuit with relatively high source impedance. It's pretty bloody safe. About the most you can realistically do is take out a couple USB ports. And if you really think you 'never know what may happen', you need to question how we make such devices in the...

    Extending a speaker cable

    They've always looked better than staples to me. And they don't crush the cable. Alternatively, use some trunking: https://www.tlc-direct.co.uk/Main_Index/Trunking_Pvc_Index/Dline_White_Index/Dline_16_8_White/index.html Paintable and comes in other colours too.

    di-log earth leakage clamp

    Hall effect devices can be very sensitive, and therein lies the problem. They are quite readily upset by other nearby magnetic fields, including that of the planet we're parked on (turn one over and you can get quite a substantial offset). Traditional current transformers are not so easily...

    Recommended CAT6 cable brands

    As long as it meets spec (and therefore isn't CCA), does it really matter who puts their name on it?

    £29 HDMI cable from Currys?

    The bitrate for 2160p24 is four times that of 1080p24. If you think cable quality doesn't matter at that point, you're kidding yourself.

    Extending a speaker cable

    I've only skimmed, but other than some minor and likely unrelated differences at low frequency (let's see the same tests run ten times in ten places and the same curves show up..), all I can see is a simple difference in delivered power.. which is nothing more than a lower impedance at work. And...

    Soldering headphone cable

    If it was soldered then it can be soldered.. If these headphones are so expensive they should have a warranty or a replacable cable assembly. Otherwise.. persist. Apply more heat, use more aggressive flux.

    Help me out with my re-wiring project? (Ethernet)

    Even cat5e CCA will do 1Gbit synchonous. You're not likely to exceed that any time soon. No it doesn't, that's just marketing speak. It has a theoretical maximum half-duplex throughput of 1900Mbps using a 40MHz channel at 2.4GHz (NO CHANCE unless there's nobody within a mile of you) and a...

    Bosch drill with broken chuck - help!

    There's likely to be a screw in there somewhere if it's a reversible drill. Give it a good clean and see, it will be left-handed. 'more powerful', it's not just about the number of supposed watts. Chucks cost less than half that.

    Automatic Wire Strippers - your opinions and thoughts please

    They are entirely the wrong type of stripper for stretchy cable like that audio cable. They will not suit for neoprene, silicone, most types of rubber, or certain PVC blends. You want a sharp knife or some thermal strippers.

    My RCD tripped once but has been OK since

    A specific class of capacitor for connecting directly between live (line or neutral) conductors and earth, where a fault could pose a shock risk. The fridge freezer might, the boiler almost certainly will, the router is 50/50. But almost any electronic device not physically disconnected or...

    My RCD tripped once but has been OK since

    It could be almost anything.. Kettles are a nice place to start if it begins happening regularly. Could easily be a Y cap in a device breaking down (they self heal), a drop of water getting in somewhere, or spiders finding a way into boxes and commiting suicide. If it starts doing it a few...
