US Government Screws Up Terrorist Watchlist, Few Surprised

Dave

It looks like [Dave Jones] got himself on a US government watch list. We don’t mean [Dave L. Jones], awesomesauce electronic wizard and host of eevblog, though. Some three-letter agency is just looking at someone named [David Jones]. Is this going to screw over our Aussie friend? You betcha.

[Dave] bought a few things through Element 14 that he would later pick up at their Sydney warehouse. When he got there, he discovered the parts were ‘on hold’. Out of curiosity, he asked what the holdup was and discovered his name was flagged on a US government watch list.

If you’re keeping score, this is an Australian citizen buying stuff from an Australian subsidiary of a UK company, and being told ‘no’ by the US government.

The folks behind the counter at the Element 14 warehouse were extremely helpful, clearing the hold and getting [Dave]’s parts in just a few minutes. This has, apparently, been going on for a while; [Dave] recalled a few times when orders showed up a few days late with the Farnell/Element 14 people apologizing with the word ‘hold’ in there somewhere.

Of course this means it’s possible for someone working at the Element 14 warehouse to clear one of these US government holds, and even if they don’t the order will still go through in a day or two. Government efficiency at its best.

This Little Piggy Stayed Home And Became A Stove

FPQRAZDHRWN9J10.MEDIUM

This little piggy probably should have gone to the market. Instead, its become an extremely decorative, and cute, wood burning stove!

After being inspired by a similar Instructable that guides you through the creation of a wood stove using an expired gas cylinder, [Ruudvande] had to try it himself. The problem was — he didn’t have a gas tank. Luckily for him, he found someone who did, but as it turned out, they wanted to turn it into a barbecue! So, slightly sidetracked, he built them a barbecue using the center of the cylinder, and got to keep the ends and enough steel to make Mr. Piggy himself.

Almost the entire wood burning stove is made of scrap bits and pieces of steel, and various pieces of mounting hardware. Armed with just a MIG welder, [Ruudvande] welded it together all by hand, and we think it turned out great! He’s not quite happy with it yet though and plans to upgrade the chimney, put a larger grill inside, paint it, and even add a glass window to the door.

NXP’s ARM Micros With Motor Controllers

It’s still relitavely early in the year, and all those silicon manufacturers are coming out with new toys to satiate the engineer and hobbyist for years to come. NXP’s offering is the LPC1500, a series of ARM microcontrollers optimized for motor and motion-control applications.

The specs for the new chips include an ARM Cortex-M3 running at 72MHz, up to 256kB Flash, 36kB SRAM, USB, CAN, 28 PWM outputs, an a real-time clock. There are options for controlling brushless, permanent magnet, or AC induction motors on the LPC1500, with dev boards for each type of motor. Each chip has support for two Despite NXP’s amazing commitment to DIP-packaged ARM chips, the LPC1500 chips are only available in QFP packages with 48, 64, and 100 pins.

Don’t think the LPC1500 would be a perfect chip for a CNC controller – the chips only support control of two motors. However, this would be a fantastic platform for building a few robots, an electric car, or a lot of the other really cool projects we see around here.

Cyclone Dust Collector Requires No Bags Or Filters

After discovering their dust collection vacuum was blowing through filters and leaking powdered fiberglass dust all over their workshop, the folks at i3Detroit decided to take matters into their own hands, and built this awesome cyclone dust collector that requires no bags or filters!

They were inspired by a similar wooden sawdust collector, but as they cut many different materials, they decided to build a steel cyclone for durability. The build makes use of two 5-gallon buckets, a 5-gallon vacuum cleaner, and a meticulously designed sheet metal cyclone cone. The vacuum creates a strong suction force and the dust enters the cyclone, getting sucked to the bottom and into the blue bucket. This keeps the filter in the vacuum clean, and keeps all the debris in an easy to access bucket. Continue reading “Cyclone Dust Collector Requires No Bags Or Filters”

EL Wire Nixie Tube Is In Your Reach

FUQ84C3HS0D05D9.MEDIUM

Nixie tubes are awesome, but sometimes a little out of reach for some makers, whether it is a matter of obtaining them, or figuring out how to drive them. The hackerspace over at H3 Laboratories decided to try making a fun alternative — EL wire nixie tubes.

[Marty] leads us through the build in a very detailed Instructable, which makes use of CoolNeon EL wire. He’s using an Arduino Uno with a CoolNeon shield to control it. The trickiest part of this build is forming the numbers to minimize the overlap — to figure this out he modeled it in Blender. He created a test jig and formed the numbers using coat hanger wire first before playing around with the EL wire.

EL wire can be soldered together — it’s just a bit of a fine art, which is explained in another detailed Instructable. To black out parts of the number and the trailing wires, [Marty] made use of black plastic dip. The numbers are mounted on a Styrofoam cylinder which fits into the bottom of a large masonry jar. It’s a great build and a fun project to get into Nixies … without actually getting into Nixies.

Stick around for a video of it in operation.

3D Printing Metal Structures With A 6-axis Robot

robot printer

[Joris Laarman] is working on a project called the MX3D-Metal which uses an ABB industrial robot arm and a welding machine to create strong metal structures on any working surface and in any direction.

He started last year with the MX3D Resin printer, which is the exact same concept, but instead of metal, it uses a two-part epoxy that bonds instantly upon mixing. Their lab is located in Amsterdam, and they work closely with IAAC (the Institute for Advanced Architecture of Catalonia) — Autodesk provides funding for the research.

[Joris] has successfully printed complex structures using steel, stainless steel, bronze, copper, and even aluminum. Poking around their website you can find many examples of different things they have printed, including intricate matrices of multiple curved lines which end up looking more organic than mechanical. It uses mostly the same concept as the Rostock Welding robot we covered a few months ago, which is open source and fairly cheap to make at home!

Stick around for a video of both the MX3D-Metal and Resin robot printers in action!

We Salute The Television Tube Flag

From [Gijs] comes Beeldbuis Vlag Tijsdlijn, or television tube flag (Translated). We’re not up on our Dutch, but it appears that [Gijs] and friends have created a television tube which waves much like a flag in response to airflow from a fan.  The effect is pretty darn amazing, and that’s putting it mildly. To create this hack, [Gijs] built a modified Wobbulator. The Wobbulator is an early video synthesizer which used added steering coils to modify the operation of a standard TV tube. When excited, the coils would deflect the tube’s electron beam, causing some rather trippy images to appear on-screen. (Yes, here at Hackaday “trippy” is a scientific term).

[Gijs] wanted his screen to be “waved” by a fan, just like a flag would wave. To do this he used an anemometer made of ping-pong ball halves. The anemometer spins up a DC motor from a CD-ROM drive. In this application, the motor acts as a generator, creating a DC voltage. An ATmega328 running the Arduino code reads the voltage from the motor. If the anemometer is spinning, the Arduino then outputs a sinusoidal value. The Arduino’s output is amplified and applied to the coil on the CRT. A network of power resistors ensures the amplifier is correctly loaded. The results speak for themselves. In the video after the break, the tube flag is displaying a slide show of photographs of its construction. As an added hack, [Gijs] used an Arduino Leonardo as a USB keyboard. When the anemometer spins, the primary ATmega328 sends a signal to the Leonardo, which then emulates a push of the arrow keys on the host computer. This lets the tube flag advance its own images. Very cool work indeed!
