Drilling precise grids without a CNC machine can be tough to pull off. [Ookseer] has come up with a nifty method for dilling aligned holes with a drill press. He uses a right-angle jig on a Dremel drill press with stacks of business cards as spacers. The same number of cards is added between the substrate and the jig to space each new hole evenly. This method comes in handy when drilling grids in an enclosure for speakers, temperature sensors, or for an aesthetically pleasing design.

[Don] was having issues with dust when working with MDF. He had a shop vac overheat and die because of it. When looking for solutions, he saw several systems that used cyclonic dust seperation. Not wanting to buy something he could make for cheaper, he left the store and started scrounging parts. You can see his home made system in the video above. This seems like an absolute must have item for any workshop. Great job [Don].

Here is a nice video to wind down the day. It’s [neorazz]’s micRo playing the theme from Tetris. The micRo is a simple CNC kit sold by the team at Lumenlabs. For more servo music, peruse our CNC category.

Here’s an interesting concept, the bot pictured above has no internal control mechanisms. His claims to have built the smallest bot are dubious, considering it requires a much larger control platform to function, so lets just set that aside and look at how it works. The bot itself is basically a hollow box with a hinged manipulator mounted on it. He has then built a modified CNC type structure with various magnets below a platform. The magnets can move the bot and control the manipulator (assuming the bot isn’t trying to pick up anything magnetic). He talks about this being a possible control scheme for smaller bots, though we think he would have to make some major advancements to his magnetic controls for accuracy’s sake. As for his claims of being the smallest, well, we’re sure we’ve seem similarly sized bots, even hexapods, that were completely self contained.
Is this the beginning of a new trend? We’ve seen case modding in computers for a while now, but are we going to start seeing extreme case modding for our CNC machines? This is Kali. Kali eats plastic and pukes parts. Nice.
After the recent announcement of the re-release of the candyfab, [4volt] had to give a run at melting sugar with a laser. It turns out that a 40w co2 laser works great. They don’t currently have a method of layering, so everything is one layer currently.You can see the results of different speeds and power ratings on the site. The next party they throw will have some pretty fancy tasty treats.
Forget about machines that can replicate themselves, what we want is a machine capable of making an 8 inch wide hollow torus out of sugar. The CandyFab project has been around for a while, but with the release of the new machine, the CandyFab 6000 they are reinventing the project. Built from the ground up to be a candy constructing beast, the CandyFab 6000 might be a little smaller than the previous version, but it’s much better designed. You can get more details on the new wiki site.
