First, a ScrapHappy New Year to you all!
To start the year, here is an easy ScrapHappy mend of an LED lamp which the Snail uses for various crafty activities. In fact, we have two of these lamps and, although they weren’t cheap, they are well made and very useful. They feature a ring of LEDs as well as a magnifier in the top, and will run from batteries or a mains adapter. The Snail uses the mains adapter for both – the batteries are housed in a detachable box which I may well use for something else one day (watch this space!).
This particular lamp started to be like me – a bit dim. This is a strange thing for LEDs to do as they aren’t like incandescent bulbs that have separate parts that can fail independently (so one of several filaments might break but the others would keep on shining). It probably meant that the power supply wasn’t doing what it was supposed to, so I started there. A quick check with my rusty voltmeter told me the truth – the supply was only half decent. It was producing a little over 3 volts rather than 6 volts to be precise.
In the last 20 years, I reckon every household has probably had about a million* mains power supplies that have long since become pointless because the device they were supposed to power has broken. Many have (shamefully) been put in landfill, but many reside to this day in old boxes at the backs of cupboards/wardrobes/sheds. Mine reside in my office/workshop/studio, liberally scattered across shelves/boxes/drawers.
Could I find one that was suitable?
Yay! I could! This is the supply from an old set-top box, for receiving the Freeview digital signals (for my non-UK reader, Freeview is the UK’s contribution to the vast thousands of utterly unwatchable TV channels around the globe). We stopped using the box it powered about ten or so years ago but *I KNEW* it was worth keeping.
Of course, it didn’t have the right bit on the end of the wire so I had to chop the end of the defunct power supply and solder it onto the “new” supply. Once done, voila! LEDs that are properly bright. And perhaps a hint of a smile in the magnifier too? Perhaps…
* I checked with Twitter – it is a million.
