Fresh hacks every day
Everyone’s favorite Open Hardware store – Seeed Studio - was at Maker Faire this last weekend. They showed off a bunch of cool toys, oscilloscopes, Arduino shields and other hardware goodness, but one of the more interesting products was from their B Squares line.
As [Colin] from Seeed showed us, each B Square is a small plastic enclosure … Read the rest
[Nick] is working on a prototype of a coffee table sand plotter that draws patterns in sand a lot like a zen rock garden.
[Nick]‘s zen rock garden uses a magnet to draw a ball bearing across the sand in interesting patterns. The build uses 3D printed gears and laser cut parts to rotate the table around and move the … Read the rest
[wesdoestuff]‘s mother needed a clean way to mix together fragrance oils. Being the stand up kinda guy he is, [Wes] threw together a few spare parts to make this Magnetic Stir Plate.
The whole setup is amazingly simple. Pry the fins off of an old computer fan, glue a couple magnets to the fan’s hub. Drill a hole for … Read the rest

[Sparr] found himself the proud owner of one thousand rare-earth magnets and decided to see what geometric shapes he could build with the spheres. These are gold-plated N35 Neodymium magnets that measure just 6mm across. He discovered that every structure is built from rings of … Read the rest
[Oleg] of Circuits@Home and maker of the USB Isolation Board and the USB Host Shield has a new, two-part hack for his chemistry set. In Part 1 of this hack, [Oleg] discusses the method he uses to make a stir bar spin and what types of stir bars work the best. Part 2 discusses the motor control code … Read the rest
Sometimes we forget just how useful magnets can be. Sure, we use them in some projects, but usually we just pull them apart for our amusement. Evil mad scientist laboratories reminds us that they can be useful tools. They’ve made a list of 17 uses of magnets. We’re also reminded that magnets can be dangerous. What else … Read the rest
