Make reader RoboGeek has been playing with a Spectrum Z510 3D printer, whipping up science fictional objects out of bits and atoms.
One of the objects is a "metatron" by Bathsheba Grossman. The red polyhedral sphere is the work of George Hart (http://www.georgehart.com/rp/rp.html) and is actually 7(!) nesting spheres, I assigned a different color to each one. I hope one day to print that one out of plastic. When you take an object out of the "build tray", you place it in a dust cabinet and blow off ant excess powder with a needle tipped airbrush. Then you CAREFULLY "infiltrate" it with cyanoacrylate. I did this by dipping one of those little red coffee stirrers you find in office kitchenettes, and applying it one drop at a time. Having a touch of OCD helps this procedure. ;-) We used Loctite 408, as it was less expensive than buying replacements from ZCorp. MicroMark sells little paint/glue brushes that are small plastic handles with fuzzy flocking on one end. The Serenity is from a poly mesh sent to me by Sean Kennedy, aka Treybor in the 3d computer modeling community. I don't recall where I got the Hawk Mark IX mesh from. The Z510 can print from vrml models. None of these are painted; the Z510 prints in color. Good joke: the software comes with a jpg of the IniTech (Office Space) logo! Note the logo on the command cabin of the Hawk Mark IX. The Lego gears I designed in AutoCad 2002. The yellow one is a replica of a 40-tooth Lego Technic gear, the largest they make. The others are 56 & 96-tooth, I designed for use as parts in an all-Lego clock.
In Insurance coverage of customers induces dishonesty of sellers in markets for credence goods , a research paper in PNAS by German and Austrian economists, the authors show experimental evidence that electronics repair shops are more likely to overcharge for labor when their customers have insurance.
Techpowerup caught hardware giants MSI and Asus shipping them graphics cards that were preset for a software-based overlock mode, meaning that the cards performed better out of the box for reviewers than they would for customers.
Some truths are universal. For one, your phone will always run out of power when you most need it. For another, the charging cords that come packaged with your Apple device will fray, split, and rip faster than Usain Bolt in a game of tag.Instead, pick up a charging cord that anyone would have a tough […]
Some people say magic tricks are nerdy and best left to your 12-year-old asthmatic cousin. But others see value in perfecting the slight of hand and showmanship associated with a perfectly executed routine. We’re firmly in the latter camp. And now, we’re giving you the ability to put a few parlor tricks up your sleeve with the Penguin […]
Bluetooth speakers may be convenient to use, but many of them just aren’t that powerful. Sure, it may be fine if you’re seated in front of the speaker. But move across the room, and you may strain to hear what’s coming from those tiny drivers.There’s a reason why the G-BOOM Wireless Bluetooth Boombox (now $79.99 in the Boing […]
