Kickstarter Incurs The Wrath Of Arduino Creator

[Massimo], one of the creators of the Arduino, is a little perturbed over what passes for the truth over on Kickstarter.

While [Massimo] does recognize that Kickstarter can be a force of good launching garage-designed projects into the hands of willing consumers, he noticed something was a little fishy with the recent smARtDUINO kickstarter (notice the capital letters, by the way). Right near the top of the smARtDUINO’s kickstarter page is the phrase, “For years we manufactured the ARDUINO in Italy. Now we created a new Open System: modular, scalable, the world’s cheapest and smallest!”

Being at the top of the Arduino organization, you’d think [Massimo] would have heard of these former Arduino manufacturers. The name didn’t ring a bell to him, so he called up the factory. No one at the factory had heard of them, and after a long search it was finally revealed the head of the smARtDUINO project hired two factory workers who worked for a supplier the official Arduino manufacturer uses.

[Massimo] makes the comparison of, “if he hires two factory workers from Ford he can claim he used to manufacture Ford cars.” We’re thinking that’s a little generous. It’s more like hiring two people who used to restock the vending machines in a Foxconn plant and claiming you used to build Apple computers.

With a simple trademark infringement on his hands, [Massimo] contacted Kickstarter to see what could be done. Kickstarter replied:

Thanks for writing in and bringing this to our attention. This is a matter that must be taken up directly with the project creator. You can contact them by clicking “Contact me” on the project page.
Best,
Kickstarter

For [Massimo], and us, that’s just not a sufficient answer. We’re thinking Kickstarter has an obligation to vet their projects and make sure the creators of these projects are who they say they are.

But enough about what we think. What do you, the Hackaday reader, think about this situation?

[Prusa]’s Nozzle Prints Polycarbonate, PEEK, & Nylon

Oh, we’ve been sitting on this one for a while.

[Josef Prusa], brainchild behind what is probably the most popular 3D printer, has just unleashed a new hot end that is capable of printing objects in polycarbonate, PEEK, and nylon.

This new hot end is completely made out of stainless steel – there are no plastic parts made out PTFE or PEEK to keep the heat from transferring up to the extruder. Because the Prusa Nozzle can print these plastics, it’s also now possible to print parts for other hot ends such as the J Head and the Budaschnozzle.

We ran into [Prusa] at NYC Maker Faire a few months ago, and he was kind enough to go over the advancements in his new nozzle and new i3 printer. So far, it looks like the lack of a PEEK insulator isn’t doing the new hot end any harm – [Prusa] has left molten plastic in the nozzle for a few hours and nothing bad has come of it.

You can check out the interview below.

Again, thanks to [Prusa] for granting us an interview and providing some free advertising for Hackaday’s hosts for the NYC Maker Faire. Before you complain about the delay in getting this interview out to you, don’t worry; I slapped a few Makerbot stickers on the back of [Prusa]’s jacket. Everything’s cool.

Hola! From A Spanish Speaking Drawing Arm

[Acorv] wrote in to tell us about his latest hack, a robotic arm that writes with a marker. In the video after the break, the arm is set to copy whatever someone writes in a touchpad. As you might guess from this video, the hack is written up in Spanish, but it’s nothing your favorite translator can’t handle if you don’t speak the language.

This robot it the result of improvements on his first drawing arm ‘bot featured here. The basic kinematics stayed the same in the arm’s second iteration, but the resolution was greatly improved by using belts to achieve a gear reduction. The second build also features mechanical reinforcement with an Erector-set style building set known as [Mekanex].

A simple hobby servo moves the marker up or down, and control is achieved through, you guessed it, an Arduino with a motor shield! Although from a different time, the way this arm is used is reminiscent of a mechanical writing automaton from long ago. Continue reading “Hola! From A Spanish Speaking Drawing Arm”

Electronically Augmented Foosball Brings Competition To The Office

This office has a Foosball league that automatically tallies and posts the standings for each employee. This is thanks to all of the extra electronics that were added to the Foosball table in the break room.

The system is connected to the internet via WiFi. This allows it to store the final results of each game for use on the leader board. Player first identify themselves to the system using the RFID tag embedded in their employee badge (normally used to open doors in the building). From there the game play proceeds much like you’d expect, but the scoring is handled automatically. Each goal has a laser pointed across it which is broken when the ball passes through. But there are a pair of arcade buttons in case of a scoring error.

Standings are listed at the webpage linked above. There’s even functionality for new employees to registers through this page. Don’t miss a glimpse of the build in the clip after the break.

LEGO LP Player

This LP player is made entirely out of LEGO parts. It plays the songs encoded on each record, but not by using a stylus in a groove. Instead, each LP has a color code on the bottom of it which is interpreted by the optical sensors underneath.

In addition to its functionality [Anika Vuurzoon] made sure that the build looked the part. The horn is a nice touch, but you’ll also appreciate the rotating mini-figures on the front side of the base. To the right there is a hidden door that provides access to the NXT brick which drives the system. New records are produced using a couple of different tools. First off, the song is written using Finale, a mature musical notation program. That is exported and run through a second program which produces the colored disc design which is applied to the records. You can hear the songs for yourself in the clip after the break.

If LP playing toys are right up your alley you’ll want to check out this 3D printed record hack for a Fisher Price toy.

A Folded Horn Enclosure To Make The Most Out Of A Subwoofer

To make the most out of his home theater sound system [Baccula] built this folded horn enclosure for as much bass sound as possible. The design was conceived by [Bill Fitzmaurice] who thought there needed to be a better way to use the subwoofers which are typically used in home systems. His design is called the Tuba HT and it is aimed at a 15″ speaker. [Bill] charges for the building plans, but we don’t mind living vicariously through [Baccula’s] construction album.

As you can see, there are a lot of wood parts that went into the cabinet. It starts with a base of 2×4 framing. From there the plywood sawdust really starts to fly as each component is produced. During assembly [Baccula] is careful to fully glue each joint — you don’t want to find out that your sub cabinet vibrates after you get everything installed. All together the new piece of living room furniture stands three feet tall and deep and two feet wide.

The album has no captions but you can read a bit more about the project in the Reddit comments.

Android VOIP Phone And Raspberry Pi Mate For An Intriguing PBX Setup

[Ward Mundy] has found something great by combining a GXP-2200 phone with Raspberry Pi to create a private branch exchange. So the idea behind a PBX setup is kind of like a company intranet. All of the phones in the system are assigned an extension number and have access to the internal system functions like voice mail, and sharing phone lines to the outside world. We’ve talked about using an RPi as a PBX before, but the high-tech phone he’s using this time around pulls everything together remarkably well.

The GXP-2200 is available for under $200. It runs Android and has a full color touch screen pictured above. It is marketed as a multimedia phone and indeed it brings Skype and Google Voice to the party. But it also offers six SIP lines. The hardware even seems to be planned for this type of use as the phone offers a second Ethernet port to which the RPi board can be connected. In this example [Ward] simply screws the RPi to the phone’s plastic stand and connects the two using a six-inch cable. From there the PBX can be configured with the phone’s browser. How’s that for slick?
