Thursday, March 20, 2014 - 22:29Fluke Issues Statement Regarding Sparkfun’s Impounded Multimeters
Fluke just issued a response to the impounding of multimeters headed for market in the United States. Yesterday SparkFun posted their story about US Customs officials seizing a shipment of 2000 multimeters because of trademark issues. The gist of the response is that this situation sucks and they want to do what they can to lessen the pain for those involved. Fluke is providing SparkFun with a shipment of genuine Fluke DMMs which they can sell to recoup their losses, or to donate. Of course SparkFun is planning to donate the meters to the maker community.
Anyone with a clue will have already noticed the problem with this solution. The impounded shipment of 2k meters will still be destroyed… eh. The waste is visceral. But good for Fluke for trying to do something positive.
Before we sign off let’s touch on the trademark issue for just a moment. We can’t really blame Fluke too much for this. The legal crux of the matter is you either defend your trademark in every case, or you don’t defend it at all. In this case it was the border agents defending the filing, but for ease of understanding we’ll not go into that. On the other hand, speaking in general business terms, the way things are set up it is advantageous to acquire a trademark specification that is as broad as possible because it helps to discourage competitors from coming to market. So trademark is good when it keep hucksters from trying to rip off consumers. But it is bad if applied too broadly as a way of defending a company’s market share.
Where does Fluke come down in all of this? Who knows. There is literally no right answer and that’s why the discussion around yesterday’s post was full of emphatic arguments. A Fluke meter is a cream-of-the-crop device and they have the right (and obligation) to ensure that reputation is not sullied. SparkFun serves a market that probably can’t afford a Fluke at this time but may some day in the future. And this is the reason we can feel okay about this outcome.
Thursday, March 20, 2014 - 21:00Fail of the Week: The Demise of Lil’ Screwy
The subject of this Fail of the Week installment is entertaining if nothing else. [Chris] decided to see what kind of forces his home-built 100 ton press could stand up to. Turns out the press failed at punching a 1.5″ hole through 1/2″ plate steel.
If you didn’t see it back in February make sure you take a gander at the premier of Lil’ Screwy. The diminutive press packed quite a bit of punch, using four hand-cranked screws to knock out holes in metal. [Chris] decided to tie-one-on and take his lathe for a spin to machine the larger 1.5″ punch set.
He probably should have known when he switched from a 4-foot ratchet to a crescent wrench with a 12-foot pipe for leverage that this was going to be more than the press could handle. The bottom plate seen in the image above is beginning to cup, which in turn jams up the screws in the off-kilter threads.
We fell a bit guilty in admitting we love to see equipment pushed to the point of failure like this. But perhaps that’s part of what this column is all about. Our favorite is still the PCB shear failure, but this comes in at a close second. Check out the video presentation after the break; just be warned that there’s a bit of rough language as part of the narrative.
Fail of the Week is a Hackaday column which runs every Wednesday. Help keep the fun rolling by writing about your past failures and sending us a link to the story – or sending in links to fail write ups you find in your Internet travels.
Thursday, March 20, 2014 - 18:00MRRF: Roundtable And Roundup
Last weekend Hackaday made a trip out to the Midwest RepRap Festival in Goshen, Indiana. We met a ton of interesting people, saw a lot of cool stuff, and managed to avoid the Amish horse and buggies plying the roads around Goshen.
We’ve already posted a few things from MRRF, including [Jordan Miller] and co.’s adventures in bioprinting, a very cool printable object repo that’s backed by a nonprofit LLC, some stuff from Lulzbot that included a new extruder, stretchy filament, and news of a 3D scanner that’s in development, ARM-based CNC controllers including the Smoothieboard and capes for the Beaglebone, 3D printed resin molds, the newest project from [Nicholas Seward], creator or the RepRap Wally, Simpson, and Lisa, and 3D printed waffles. It really was an amazing event and also the largest DIY 3D printer convention on the planet. How this happened in Goshen, Indiana is anyone’s guess, but we’d like to give a shout out to SeeMeCNC for organizing this event.
With so many famous RepRappers in one place, it only made sense to put together a round table discussion on the state of RepRap, 3D printers, and microfabrication. We have a 40-minute long video of that, which you can check out after the break.
The video above is a Q&A session with [Johnny Russell] of Ultimachine, developer for the RAMPS and RAMBo electronics boards, [Prusa] of Prusa Mendel and i3 fame, [Mike] a.k.a [Maxbots] of Maker’s Tool Works and developer of the MendelMax 2, and [Aeva], robot psychologist at Lulzbot (seriously, that’s what her card says). It’s not a lie to say these guys have had a hand in the stuff that has gone into 90% of all the RepRaps out there.
We highly suggest getting a cup of coffee and opening that video up in a new tab. There are some great comments between the four of them, and some very insightful questions from the audience. Here’s a list of the questions asked:
- What are the economics of open source and cheap clones?
- Where is the RepRap community going this year?
- How should companies incentivize less glamorous projects?
- When do we get functional mechanical parts in 3D printing?
- What are some recommendations for subtractive manufacturing toolchains?
- Where is RepRap popular around the world?
- What will happen with SLS patents expiring?
- How did you get started and how can someone new contribute?
- Can RepRap indefinitely fend off DRM?
- What are some recommendations for open source 3D modelling programs?
Also at the MRRF was mUVe 3D, makers of a very cool resin printer, and the only people in the RepRap community that have seen the light of coroplast for making non-structural panels on their machines. We also grabbed a video of them:
Once again, we’d like to thank everyone who came out, SeeMeCNC for putting this event together, Makers Tool Works for 3D printed waffle irons, and everybody else who headed out to Goshen for the largest convention dedicated to RepRaps in the world.
If you didn’t make it out, here’s some aerial footage courtesy of [Phil Briski] and his tiny quadcopter. Be sure to check out the 5 foot by 8 foot Jolly Wrencher flag, something we’re now considering putting in a Hackaday store. Hope to see you there next year!
Thursday, March 20, 2014 - 15:01Piezoelectric Crystal Speaker for Clock Radio Is Alarmingly Easy to Make
Let’s face it: most of us have trouble getting out of bed. Many times it’s because the alarm isn’t loud enough to rouse us from our viking dreams. [RimstarOrg]‘s homeowner’s association won’t let him keep a rooster in the backyard, so he fashioned a piezoelectric crystal speaker to pump up the volume.
[RimstarOrg]‘s speaker uses a Rochelle salt crystal strapped to a bean can diaphragm. In his demonstration, he begins by connecting an old clock radio directly to the crystal. This isn’t very loud at all, so he adds a doorbell transformer in reverse. This is louder, but it still won’t get [RimstarOrg] out of bed.
Enter the microwave oven transformer. Now it’s sufficiently loud, though it’s no fire bell alarm. He also demonstrates the speaker using a piezo igniter from one of those long barbecue lighters and a crystal radio earpiece. As always, the video is after the jump. [RimstarOrg] has a lot of relevant linkage in the summary so you can learn how to grow your own Rochelle crystals.

Thursday, March 20, 2014 - 12:01You are Fined 1 Credit for a Violation of the Verbal Morality Statute
Some citizens can control their language and others cannot. What is a civilized society to do? In a dystopian future you can count on electronic monitoring. But wait, the future is now… or it will be in a few weeks. [Tdicola] is building the verbal morality monitor from Demolition Man as his entry in Hackaday’s ongoing Sci-Fi Contest.
Currently the project is in the early planning phase, but holy cow this is a fantastic idea! For those that didn’t see the glorious 1993 feature film, the young [Stallone] pictured above is accepting a ticket (as in: he must pay for his violation) from the tattle-tale wall-mounted computer. Everything about this device is completely feasible using today’s tech. It needs voice recognition and a list of naughty words, a way to play a pre-recorded message, and a printer to spit out the tickets. The build log for the project outlines all of this, as well as possible cost and sources for each.
We’ve been wondering who it was that injected an Artificial Intelligence into our project hosting system. We see both [tdicola] and [colabot] are on the team for this build. The names are too conveniently similar to be a coincidence, don’t you think?
