@salbayeng: Actually my favorite hole making tool is a (hand-held) plasma cutter, you can carve any shaped hole including slots, curved holes , half holes...

Oooh -- I want to try one of those!!!



Often, like the idiot I am, I find that I have no room on my bench/desk top so I "machine" the object on my lap resulting in ripped pants and maybe a scratch or two on my leg. Plasma may turn out to have a more significant result!

@Salbayeng...Cheaper in Oz?  you must be joking.

This is where I got mine, and yes it is $60...but good value I reckon all the same:

re Jaycar...see my complaints about their meter prices in Max's blog on tools:

http://www.eetimes.com/author.asp?section_id=216&doc_id=1323332

About 2/3 way down, I give a comparison between US / OZ prices...from the same company.  As they say here in Oz....it's full 6u115h1t mate!

@Salbayeng... "I imagine a rhinocerous would make a decent size hole in such a wall?"

Well yes, but where I lived there were not too many of them nearby.  One place I lived we did get Kudu (large antelope with spiral horns) eating our roses at night, but nothing worse than that,    Elephants have been known to demolish stuctures that are not too well built by rubbing their backsides against them to get a good scratch.  But most animals are too clever (and shy) to try this sort of thing....

Drilling holes long way from a power outlet....

One of the things I picked up from Harbor freight a decade ago? , was a 2-stroke petrol driven drill, I used it to drill heaps of 1" holes in fenceposts , then having put up a  km of fences , sold the used drill for twice what I paid for it.

Aha, Saw this about a year ago in a  Jaycar ad placed in nuts and volts , the price was $30 US.

Thought I'd get it cheaper over here (Oz)  , but no...  ~$60 for us locals

Reminds me of the time I went to a great deal of trouble to carry a $20 bottle of excellent Hunter Valley chardonney all the way across the pond to friends in Buffalo, only to find the exact same wine in a bottleshop on NF Boulevarde for $10 ..

I imagine a rhinocerous would make a decent size hole in such a wall?

This is actually true and happened at a previous workplace. 

An electrician was drilling a 1/4Hole througha 1/8" steel wall to mount a cable tray or something.

All was going well until BOOM - FLASH suddenly a ragged 1" charred hole appeared, he had neglected to check on the position of the 415v 3ph feeder on the other side, fortunately the worker was not permanently injured.

 

Actually my favorite hole making tool is a (hand-held) plasma cutter, you can carve any shaped hole including slots, curved holes , half holes, and also cut through welds without damaging the metal on either side. Pity it only cuts metal (and strategically misplaced leather gloves and thumbnails...ouch).

David Patterson, known for his pioneering research that led to RAID, clusters and more, is part of a team at UC Berkeley that recently made its RISC-V processor architecture an open source hardware offering. We talk with Patterson and one of his colleagues behind the effort about the opportunities they see, what new kinds of designs they hope to enable and what it means for today’s commercial processor giants such as Intel, ARM and Imagination Technologies.
