    How to power one or two of these clusters

    what's the opinion on cobs with a built in driver that couple direct to mains such as this one? would it require a heatsink bearing in mind the backplate is aluminium...

    How to power one or two of these clusters

    hmm this is looking like a no-go with the modules I have bought but that's not a problem. I'm making a steampunk lamp for someone and I would like it if possible to run off a wall wart so the need for PAT testing is obviated (I live in the UK). If someone could suggest some components to make...

    cheers, would it be too much current if just feeding one cluster?

    How to power one or two of these clusters

    Hi, not had to worry about electrical stuff for a while but digging out an unfinished project I have come across a couple of led applications I have to finish. I bought a couple of these: https://www.joom.com/en/products/5ae6dcd88b2c3701f94ecfcc and am curious as to what sort of psu and circuit...

    Power output from a mobile phone aux socket

    To be honest Bob I was just toying with making a decent sounding extension speaker. I actually have a Sony job which cost £90 and is not that good. I was trying to keep away from having to power it if necessary but it looks like that is the only option.

    Power output from a mobile phone aux socket

    Ah, but I'm old enough to remember the 3 feet wide "portable" radio cassettes folks carried on their shoulders :-)

    Power output from a mobile phone aux socket

    Obviously it has a sufficient output to drive ear buds, but just how large a speaker would it drive? I like the idea of extension speakers but find the quality of bluetooth audio garbage so "hard wired" is the preferred option for me and if I can get away without a built in amp that would be...

    A simple one with LED strip

    For the amount I will want these look pretty good and I believe they offer a 3 year warranty : https://www.ultraleds.co.uk/300-x-3528-amber-led-self-adhesive-tape-4-8w-1500-lumen-5m-reel.html

    A simple one with LED strip

    Interesting about the "cheap" strips. I bought a 10m strip with driver in brilliant white for £18 off ebay to install in a jewellery display stand. Now 2 years later with less than 1000 hours on them they have mainly failed. A recommendation for a good supplier/brand would be welcome.

    A simple one with LED strip

    Hi folks and thanks for reading. I want to make an edge lit polycarbonate nightlight for my new grandson's nursery and the best way would be to use led tape and a suitable driver or psu. Drivers tend to be expensive (I might plan to sell some of these if the first goes okay on our local market...

    Old guy with a few questions

    Hi, as it says I'm an old guy with a few questions on things. back in the late 1990's I managed a factory making high end HMI panels that went onto Vickers warships and power plants amongst many places. Needless to say I know very little about electronics per se, my soldering definitely needs...
