Tip for drilling homemade PCBs.

Here's a quick tip .... if you're as myopic as I am, try this out...

Here's my PCB drill in it's stand. It's a foul thing. It was dirt cheap when I bought it 15 years ago ... The rubber coating on it has gone all sticky ... yuck...

Now look at the bottom...

I've mounted one of those small 3w LED's there, left over from another project...










Makes alignment of the drill bit with the pad on your PCB a breeze.....


You'll notice it's slightly off-centre, this is avoid drilling through it ....

.... yeah, you know how I found that out!
