Dremel router attachement for rotary tool


I remixed the router attachement user meirm made -> http://ift.tt/1ztkrV2

.

Just screw it onto yout router an adjust the depth of the routerbit.

.

I made the frame wider to achieve a better rest at the work piece.

I added three holes so that you can screw the attachement (with M6 screws) to a acrylic glass-plate oder a piece of plywood if you need a bigger base area of the router.

.

You need two M8 screws with a truss head and two M8 bolts for the handles.

.

I printed the parts with 0.3mm layerhigh

Dremel Safety Shield


Wear Safety Glasses!



But... This really helps deflect sparks when using a cutoff wheel, but the main reason i made it is for using the wire wheel because they fling little wires all over the place that stick in your clothes and make a mess.



Also helps keep the dust flying up in your face if your using a sanding wheel. Just spin off the accessory thread cap on the end of your dremel and thread this on. Works great on my Dremel and my Milwaukee M12 Rotary Tool.

Laminar Flow Fan plate


This is a Fan control plate design for creating a more laminar/focused flow on a fans exhaust. (This isn't a fan cover :-))



The turbulence is reduced, providing for more controlled flow and pressure.

Curved blades generated less noise but at the expense of loss in performance caused by the fact that curved blades stall (turbulent air flow) at a lower static pressure than straight blades.

Similar design can be seen in Noctua NF-F12 fans and SilverStone Air Penetrator fans.

Check this video out from SilverStone to see the concept: youtu.be/8m8fC809TK0

I've printed the 92mm and 120mm versions, and they work.

This design works on curved edge fans that rotate in counter clockwise direction (about 99.9% of fans).

I haven’t measured the change in the P-Q curve, but would imagine it creates and entire new curve.

Build Your Own Bone Conducting Headphones


Bone conducting headphones sound like strange gadgets, but they're surprisingly easy to build. This video from Tinkernut walks you through the basics of speaker technology, and in the first minute or two tells you how to build a bone-conduction speaker you could easily house in a hollowed out pair of on-ear headphones or earmuffs.


The full video is well worth a watch if you've ever been curious how speakers work or how to build your own, but the bits regarding bone conduction start around 58 seconds in. You'll need a few things for the project, namely a small DC motor and an old pair of headphones, but the rest can be done pretty easily with what you have around the house. When you're finished, you'll be able to press the speaker to the area behind your ear and turn what sounds like meaningless vibrating into actual audible tones you'll be able to hear even in loud environments.


Hit the link below to watch the full video and see the parts list for this and the "cheap speaker" outlined later in the video.
