Billy Club Texts Your Mother if you Hit Someone

Mama, just killed hit a man, Put a gun against his head, Pulled my trigger, now he’s dead.
Mama, life had just begun, But now I’ve gone and thrown it all away…

This latest piece of half-art / half-prototype from one of our favorite hacker-artists [vtol] is a billy club equipped with a GSM-module. It automatically sends an SMS to your mother with the text: “Mom, I hit a man.” He calls it the Antenna:

The idea of the project is to create a device which strictly controls the cruelty of police. As all the standard methods of control are ineffective, this project suggests the maternity as the last stronghold of human kindness and responsibility.

An Arduino is equipped with a piezo sensor to detect impact, and a GSM shield takes care of the texting. It’s an interesting concept, similar to requiring police officers to wear body cameras. You can debate the practicality, but we’re always interested in hearing about weapons monitoring tech concepts. One of our favorites has always been the DNA gun from (Judge) Dredd. Did you know there was an Internet Movie Firearms Database? But we digress, check out [vtol’s] demo video:

Using A TeensyLC To Emulate The XBOX 360 Controller

After the release of Mortal Kombat X, [Zachery’s] gaming group wanted to branch out into the fighter genre. They quickly learned that in order to maximize their experience, they would need a better controller than a standard gamepad. A keyboard wasn’t going to cut it either. They wanted a fight stick. These are large controllers that look very much like arcade fighting controls and include a joystick and large buttons. [Zachery’s] group decided to build their own fight stick for use with a PC.

[Zachery] based his build around the TeensyLC, which is a 32 bit development board with an ARM processor. It’s also compatible with Arduino. The original version of his project setup the controller as a HID, essentially emulating a keyboard. This worked for a while until they ran into compatibility issues with some games. [Zachery] learned that his controller was compatible with DirectInput, which has been deprecated. The new thing is Xinput, and it was going to require more work.

Using Xinput meant that [Zachery] could no longer use the generic Microsoft HID driver. Rather than write his own drivers, he decided to emulate the XBOX 360 controller. When the fight stick is plugged into the computer, it shows up as an XBOX 360 controller and Windows easily installs the pre-built driver. To perform the emulation, [Zachery] first had to set the VID and PID of the device to be identical to the XBOX controller. This is what allows the Microsoft driver to recognize the device.

Next, the device descriptor and configuration descriptor had to be added to the Teensy’s firmware. The device descriptor includes information such as USB version, device class, protocol, etc. The configuration descriptor includes additional information about the device configuration. [Zachery] used Microsoft Message Analyzer to pull the configuration descriptor from a real XBOX 360 controller, then used the same data in his own custom controller.

[Zachery] programmed the TeensyLC using the Arduino IDE. He ran into some trouble here because the IDE did not include the correct device type for an Xinput device. [Zachery] had to edit the boards.txt file and add three lines of code in order to add a new hardware device to the IDE’s menu. Several other files also had to be modified to make sure the compiler knew what an Xinput device type was.  With all of that out of the way, [Zachery] was finally able to write the code for his controller.

HamShield Puts Your Arduino On The Radio

Anybody can grab a USB TV tuner card and start monitoring the airwaves, but to get into the real meat of radio you’ll need your amateur radio license. Once you have that, the bandwidth really opens up… if you can afford the equipment. However, [spaceneedle] and friends have dramatically lowered the costs while increasing the possibilities of owning a radio by creating this ham radio shield for the Arduino.

The HamShield, is a versatile shield for any standard Arduino that allows it to function like an off-the-shelf radio would, but with a virtually unlimited number of functions. Anything that could be imagined can be programmed into the Arduino for use over the air, including voice and packet applications. The project’s sandbox already includes things like setting up mesh networks, communicating over APRS, setting up repeaters or beacons, monitoring weather stations, and a whole host of other ham radio applications.

HamShield operates on a wide range of frequencies and only uses a 250 mW amplifier. The power draw is small enough that the HamShield team operated it from a small solar panel, making it ideal for people in remote areas. The project is currently gathering funding and has surpassed their goal on Kickstarter, branding itself appropriately as the swiss army of amateur radio. The transceiver seems to be very robust, meaning that the only thing standing in the way of using this tool is simply writing the Arduino code for whatever project you want to do, whether that’s as a police scanner or even just a frequency counter. And if you want to follow along on hackaday.io, the project can be found here.

Punky GPS Gets The Steam Built Up For Geocaching

While getting geared up for geocaching [Folkert van Heusden] decided he didn’t want to get one of those run of the mill GPS modules, and being inspired by steam punk set out and made his own.

Starting with an antique wooden box, and adding an Arduino, GPS module, and LiPo battery to make the brains. The user interface consists of good ‘ole toggle switches and a pair of quad seven segment displays to enter, and check longitude and latitude.

To top off the retro vibe of the machine two analog current meters were repurposed to indicate not only direction, but also distance, which we think is pretty spiffy. Everything was placed in a laser cut wooden control panel, which lend to the old-time feel of the entire project.

Quite a bit of wire and a few sticks of hot glue later and [Folkert] is off and ready for an adventure!

Bread Online is a Bread Maker for the Internet of Things

An engineering student at the University of Western Macedonia has just added another appliance to the ever-growing list of Internet enabled things. [Panagiotis] decided to modify an off-the-shelf bread maker to enable remote control via the Internet.

[Panagiotis] had to remove pretty much all of the original control circuitry for this device. The original controller was replaced with an Arduino Uno R3 and an Ethernet shield. The temperature sensor also needed to be replaced, since [Panagiotis] could not find any official documentation describing the specifications of the original. Luckily, the heating element and mixer motor were able to be re-used.

A few holes were drilled into the case to make room for the Ethernet connector as well as a USB connector. Two relays were used to allow the Arduino to switch the heating element and mixer motor on and off. The front panel of the bread maker came with a simple LCD screen and a few control buttons. Rather than let those go to waste, they were also wired into the Arduino.

The Arduino bread maker can be controlled via a web site that runs on a separate server. The website is coded with PHP and runs on Apache. It has a simple interface that allows the user to specify several settings including how much bread is being cooked as well as the desired darkness of the bread. The user can then schedule the bread maker to start. Bread Online also comes with an “offline” mode so that it can be used locally without the need for a computer or web browser. Be sure to check out the video demonstration below. Continue reading “Bread Online is a Bread Maker for the Internet of Things”

Hackaday’s Interview with Arduino CEO [Massimo Banzi]

I caught up with [Massimo Banzi] at the Shenzhen Maker Faire to talk about manufacturing in China, the current and future of Arduino, and how recent events may shape the Open Hardware landscape.

The big news from Arduino at SZMF is a new partnership with Seeed Studio to manufacture theGenuino. This is an official Arduino board manufactured in China for the Chinese market. Knowing that the board is official and connected to the founders is key point to get makers to adopt this hardware. [Massimo] makes a good point about the ideal of “Proudly Made in China” which I could see as a selling point for the burgeoning maker market there. This may be a growing principle in China, but in an ocean of clone boards it sounds like a tough path forward. On the other hand, their booth was mobbed with people putting in new orders.

[Massimo] belives the current Arduino strife has actually served to move the project forward. He cites the schism between arduino.cc and arduino.org for catalyzing manufacturing partnerships with both Adafruit Industries and Seeed Studios. This has resulted in official Arduino hardware that is not made only in Italy, but made in the region the hardware will be used; NYC for US orders, Shenzhen for China orders.

Our discussion wraps up with a plea from [Massimo] for the Hackaday community to be a little less fickle about projects using Arduino. That one makes me chuckle a bit!

Restoring An Espresso Machine To The 21st Century

[Rhys Goodwin] has a wonderful Italian espresso machine, a Brasilia ‘Lady’. But the electronics in it are a bit outdated. So he decided to give the entire thing an overhaul, while keeping it as original as possible!

As far as espresso machines go, this model is pretty simple. It uses a 300mL brass boiler with a 3-position solenoid valve. The thermostat is one of those simple bimetallic button thermostats which sadly, aren’t even that accurate — you couldn’t build a simpler machine, there’s not even a microcontroller in it. [Rhys] had his work cut out for him.

Arduino. PID controller. LCD display. New custom machined components, including a polished aluminum face plate for the LCD! He didn’t skimp out on this restoration. He even designed his own custom PCB to house the Arduino and provide the outputs for his new electronics, impressive!
