If you want to pretty up your project boxes, we can’t imagine anything better than [Shaun]’s walnut plywood, laser-cut, kerf bent Arduino case. Instead of the slot-and-tab construction of traditional laser-cut enclosures, [Shaun] used a technique to bend plywood without steaming, heating, and eventually scorching his somewhat expensive plywood.
This isn’t the first time we’ve seen this accordian style laser-cut kerf bend. By alternating laser cuts along the desired radius, the plywood can be bent by hand. The technique is called kerf bending and is perfect for putting an organic touch on the usual 90° angle project boxes we see.
[Shaun] has an Instructable for the smaller boxes that are part of his Arduino powered wireless sensor network. This Instructable goes over the pattern of laser cuts required to get a nice, smooth kerf bend, and also shows off how beautiful a laser-cut project box can be when cut out of aromatic cedar.
Here’s a laser cutting technique that makes thin plywood bendable. By cutting away elongated diamond shapes from the material, a lattice of strips connected minimally by alternating tabs is left over. The wood is then bendable, and it must be somewhat durable since the idea came from a product that uses the technique as a hinged notebook enclosure.
We don’t have much interest in it as an often used pivot point as surely it must be a problem with long-term use. But we love the look of it as a rounded corner on an enclosure like the Arduino project box seen above. The side walls are one continuous piece, with identical top and bottom sections which receive the alignment tabs. The whole thing is held together with just four bolt/washer/nut combinations.
But if you don’t have access to a laser cutter, we guess you’ll have to stick to altering pre-made enclosures for now.
For his wedding [Dave] wanted to have a photo booth but the $1k rental price was really getting him down. Instead, he decided to build his own. This cost less money and he gets to keep the booth once the festivities have concluded. He started by designing the assembly in Sketchup, taking into consideration the portability requirements that allow this to fit through doorways. What he came up with is a unit made from one sheet of plywood that folds up via piano hinges and takes about eight minutes to set up (video after the break). But where the design really shines is the all-in-one electronics module seen modeled on the right. It houses the monitor and the computer in one compact and rugged package.

[Daniel’s] horrifying hexapod makes us wish we were sitting next to a laser cutter. The parts are cut from 4.9mm plywood and include laser-sculpted sections to allow the twenty servos to properly seat in their mounting spaces. We would suggest that you build it in secret so as not to ruin the surprise when your house mates come home to find this romping around their room.
Sadly, we couldn’t find video of this in action but go look at this other hexapod if the still shots aren’t good enough. Adding two legs to the party, you behold the video after the break of the 8-legged spider milled from ABS.
