Desklamp conversion to 12v DC 20w power supply

Picked up a halogen desk lamp from a street hard rubbish pile the other day. This particular desk lamp model has been a popular product for many years and appears to be still available. As I stood on what Melburnians strangely refer to as a ‘nature strip’, starting at someone else’s pile of junk, I faced a familiar dilemma– take it and do something with it, or walk away.

On repair

My mower broke last time I used it. Payback for all the times I have mistreated it, yanked its handle, tilted it on 2 wheels over a gutter, or banged it roughly into a tree stump. The chassis rusted out where the handle attaches, so much so that the handle on the left side pulled off, taking with it a nicely rectangular chunk of rusted mower.  So I did what any self respecting man would do. I left it in the shed and ignored it.
