I saw this video on CNC Engraving using a Diamon Drag Bit and I thought others might find it interesting as well.
I'm a software developer, currently working for Mozilla. I have a keen interest in robotics, electronics, metal-working and wood-working.

RE: Green Filament (that should come in many colours)
@pierre My understanding is that ABS shrinks more than PLA, and this is what causes the size differences when printing the same STL file using the different filaments. I believe PLA shrinks by about 0.1-0.2% where ABS is 0.4-0.8% This is also part of why ABS warps more than PLA.
@Grant-Fraser I think you’re confusing PVA with PLA. PVA (which is essentially white glue) can be washed away. PLA, is definitely not going to wash away.
RE: Table Saw Donation from KMS
The saw is basically using a capacative detector (and people are basically large capacitors). Cutting any type of metal (like aluminum) will definitely trigger it. I’m not sure about other materials, but I wouldn’t be surprised if damp wood would also trigger it.
I believe that there is a bypass mechanism which disables the safety feature so that you can cut things that would otherwise trigger it.
RE: Do we have a pocket hole/kreg jig at the space?
I have a bunch of Kreg stuff I’d be happy to loan out, but you’d have to come and pick it up from Blind Bay (about an hour drive from Kamloops).

For the next 1.5 hours, you can get the book “MySQL for Python” for free from:
RE: Makerspace Design Lab proposal
I have one of these: http://www.czur.com/ (from the indiegogo campaign - not the pro version) that I got for my wife, but by the time I got it she wasn’t able to use it.
So it’s currently sitting in the box it came in. I’m more than happy to lend this out to anybody who would get use out of it.
Another reason to use KiCAD instead of Eagle
AutoDesk (the new owners of Eagle CAD software) announced that EAGLE can now only be purchased on a subscription basis. They’re still offering the free version for non-commercial uses, but if you need to upgrade to a commercial version (because you’ve decided to sell the product you designed) then you no longer have the option of purchasing Eagle outright, only the option to buy a subscription.
