[Dorkyducks] is a bit of a jeweler, a bit of a carpenter, and a bit of a hacker. They’ve taken some time to document their technique for making bentwood rings. Bentwood is technique of wetting or steaming wood, then bending or forming it into new shapes. While the technique is centuries old, this version gets a bit of help from a modern heat source: The microwave oven. [Dorkyducks] starts with strips of veneer, either 1/36″ or 1/42″ thick. The veneer is cut into strips 1/2″ wide by about 12″ long, wrapped in a wet paper towel, and microwaved. The microwave heats the water in the towel, steaming it into the wood. This softens the wood fibers, making the entire strip flexible. The softened wood is then wrapped around a wooden preform dowel and allowed to dry for a day or two.
Once dry, the wood will hold the circular shape of the dowel. [Dorkyducks] then uses masking tape to tack the wood down to a new dowel which is the proper ring size for the wearer. Then it’s a superglue and wrapping game. The glue holds the laminated veneer together, and gives the ring it’s strength. From there it’s sanding, sanding, sanding. At this point, the ring can be shaped, and inlays added. [Dorkyducks] shows how to carve a ring and insert a gemstone in this gallery. The final finish is beeswax and walnut oil, though we’d probably go for something a bit longer lasting – like polyurethane.
Generative design is a method of creating something by feeding seed data into an algorithm. It might be hard at first to figure out how someone would build a business around this, but that’s exactly what Nervous System has been doing with great success. The secret is not only in the algorithm, but in how they’re bringing it to life.

North Korean drones! Yes, your local hobby shop has the same aerial reconnaissance abilities as North Korea. Props to Pyongyang for getting v-tail mixing down.
There’s nothing quite as satisfying as the look of a well laid out resistor array, and the folks at Boldport have taken this to a new level. It’s an art piece, yes, but these would make fabulous drink coasters.
Here’s something even more artistic. [cpurola] found a bunch of cerdip EPROMs and bent the pins in a weird chainmaille-esque way. The end result is an EPROM bracelet, just in time for mother’s day. It’s a better use for these chips than tearing them apart and plundering them for the few cents worth of gold in each.
[John] still uses his original Xbox for xmbc, but he’d like to use the controllers with his computer. He never uses the third and fourth controller ports, so he stuck those in his computer. It’s as simple as soldering the controller port module to a connector and plugging it into an internal USB port. Ubuntu worked great, but Windows required XBCD.
[Kerry] has modified an FT232 USB/UART thingy as an Arduino programmer before. The CP2102 USB/UART is almost as popular on eBay, a little less expensive, and equally suited for ‘duino programming. It requires desoldering a resistor and soldering a jumper on a leadless package, but with a fine solder tip, it’s not too bad.
[Patrick] met someone, and then some stuff happened. Good for him. Because of this, [Patrick] found himself in need of a pair of engagement rings. With a friend, some titanium bar stock, and an awesome lathe, he turned out a few awesome rings and also managed to selectively anodize them with a subtle rainbow of colors.
Making a ring on a lathe is a relatively simple ordeal, but the two larger rings [Patrick] made (one was for a friend) featured some interesting patterns that aren’t easy to make without a good CNC setup. Luckily, this friend has an awesome CNC with a rotary fourth axis.
With the machining out of the way, [Patrick] then turned to anodization. This was done by constructing a simple power supply with a variac, four diodes, and a big honkin’ cap. He managed to get a good result with a sodium carbonate solution. He doesn’t have any good pictures of it, but by varying the voltage from 20 to 100 Volts, the color of the anodization will change from green, purple, to yellow, to blue.
[Agy] a fabric hacker in Singapore has made a chic light sensitive LED necklace, and written up the tutorial on her blog Green Issues by Agy. The lovely thing about this hack is that it doesn’t look like a breadboard round her neck, and most of the non-electronic components have been upcycled. [Agy] even used Swarovski crystals as LED diffusers for extra bling.
Using a LilyPad Arduino with a light sensor and a few LEDs, [Agy’s] circuit is not complicated. She seems to be just branching out in to wearable tech, so it is nice that she learnt to program different modes for bright and low light (see video below). Her background in sewing, refashioning and upcycling does show through in her crafty use of an old pair of jeans and lace scraps for this project.
We love tech focused jewelry like [TigerUp’s] LED matrix pendants or [Armilar’s] Nixie-ify Me Necklace, but they do scream Geek. DIY electronically enhanced accessories are becoming more commonplace with the variety of micro-controller platforms expanding rapidly. Low energy wearable boards like MetaWear are making it easy for the tech to be discreet and easily connected to your smartphone. 3D printing is enabling us to create durable enclosures, settings and diffusers like the ones used for LED Stegosaurus Spikes. With all these things, hobby wearable projects can not only be functional and durable, but can also look great too.
Do you think this necklace would look out of place in a non-geeky gathering? Have you got any helpful tips for [Agy’s] code? Have you tried using gems or crystals as diffusers and what were the results? Let us know in the comments below.

The diamond engagement ring is arguably the most universally adopted of all jewelry. It’s artwork that even the most common men and women appreciate, and it’s creation calls for skills that go back centuries. [Jerome Kelty] crafts custom jewelry from platinum. Here’s an in-depth look at his process.
The first step of his Instructable post is so long you might be fooled into thinking it’s the whole post. He shows off the equipment that he used in taking this ring from design to reality — we thought the use of beeswax to pick up small stones is an interesting technique.
Click through the steps to see that he starts with a cad drawing. This model is sent offsite for casting and arrives back as an oversized blank which he then begins to clean up. A range of differend files bring it to its finished shape. He preps the areas where stones will be set. A trip to the buffing wheel gives it the shine it needs before the diamonds are put in place.
Regular Hackaday readers may recognize his name. When [Jerome] isn’t making jewelry he’s building animatronics, like Predator or Stargate replicas.

The 6th generation iPod nano makes a wonderful watch, but something milled out of aluminum doesn’t lend itself to more formal events. [Ted] liked the idea of an iPod nano watch, but wanted to kick things up a notch and fabricate an 18k gold iPod nano. It took 500 hours and $2500 in materials, but we’d say it’s worth it.
The new 18k gold enclosure for the watch was fabricated using the lost wax casting method. First, all the electronics and buttons were removed from the iPod, then a negative mold was made in silicone rubber. A positive wax mold was made with the silicon mold, and finally another negative mold – this time in plaster – was made by vaporizing the positive wax mold in a furnace.
[Ted] used two one-ounce coins as the source of gold for his nano enclosure, spun into the plaster mold. From there, it’s just a simple but tedious matter of cutting the sprues off, shaping, filing, buffing, and polishing. With a new leather strap, the iPod is reassembled in its new enclosure.
Wonderful work, and amazingly impressive from someone who doesn’t consider himself a jeweler.
