The Arduino Birthday Cake is No Lie
http://hackaday.com/2015/10/07/the-arduino-birthday-cake-is-no-lie/
Making someone a birthday cake is very thoughtful, but not if they are watching their weight. [MrFox] found a way around that: an Arduino-powered birthday cake. Even if you don’t mind the calories, an Arduino cake is a novelty and sure to be a hit with a hacker who’s another year older.
The cake uses a UTFT LCD shield which eats up a lot of pins and memory, so the project uses an Arduino Mega. A speaker plays the happy birthday song (which may even be legal now) while a microphone detects the birthday boy or girl blowing out the virtual candles.
The video shows the birthday cake in action.

Bootstrapping Motion Input with Cheap Components
http://hackaday.com/2015/10/07/bootstrapping-motion-input-with-cheap-components/
Let’s get one thing straight: This device isn’t going to perform like a Leap controller. Sure the idea is the same. Wave your hands and control your PC. However, the Leap is a pretty sophisticated device and we are going to use a SONAR (or is it really SODAR?) device that costs a couple of bucks. On the plus side, it is very customizable, requires absolutely no software on the computer side, and is a good example of using SONAR and sending keyboard commands from an Arduino Leonardo to a PC. Along the way, I had to deal with the low quality of the sensor data and figure out how to extend the Arduino to send keys it doesn’t know about by default.

Camera Dolly uses Makeblock
http://hackaday.com/2015/10/08/camera-dolly-uses-makeblock/
We’d call it a robot, but [Eric Buijs] calls it a dolly. [Eric] bought a Makeblock starter robot kit last year, but never did anything with it. He recently wanted a camera dolly to help shoot project videos and the Makeblock hardware fit the bill.
Speaking of the computer, the Makeblock kit came with an Arduino-compatible board called a Baseshield.
he junked the Baseshield and replaced it with an Arduino Leonardo.

Controlling Guitar Amps With Servos
http://hackaday.com/2015/10/09/controlling-guitar-amps-with-servos/
[fichl] plays electric guitar, and with that hobby comes an incredible amount of knob twisting and dial turning. This comes at a cost; he can’t change the settings on his small amp without taking his hands off the guitar. While larger, more expensive amps have multiple channels and footswitches, this tiny amp does not. Instead of upgrading, [fichl] came up with a device that turns his single channel amp into a completely programmable one, with just an Arduino and a handful of servos.
The footswitch is the brains of the setup, with three buttons, four LEDs, and a DIN-5 output jack that delivers power, ground, and three PWM signals to the servo box.

Hacked Apartment Intercom Barks at You or Buzzes You In
http://hackaday.com/2015/10/08/hacked-apartment-intercom-barks-at-you-or-buzzes-in/
Forgot your apartment keys? If you’ve got a ritzy building with a doorman, no problem. If your digs are a little more modest, you might only have an intercom panel that calls up to your apartment so someone can buzz you in. But if nobody is home, you’re out of luck. That’s why [Paweł] spent an hour whipping up an intercom connected automation system pack full of goodies.
The design is pretty simple – an ATMega328P to snoop on the analog phone ringer in the apartment when the intercom call button is pushed, and a relay wired in parallel with the door switch to buzz him in. For added security, the microcontroller detects the pattern of button presses and prevents unwanted guests from accessing the lobby.

Show a Quadcopter Flight on Google Earth for Under Ten Bucks
http://hackaday.com/2015/10/16/show-a-quadcopter-flight-on-google-earth-for-under-ten-bucks/
[Joop Brokking] wanted to know where his quadcopter was and had been. He thought about Google Earth, but assumed it would be difficult to get the GPS data and integrate it with Google’s imagery. But he discovered it was easier than he thought. He wound up spending around $10, although if his ‘copter didn’t already have GPS, it would have been more.
Hardware-wise, [Joop] made a pretty straightforward data logger using a small Arduino (a Pro Mini) and an SD Card (along with an SD breakout board). With this setup, NMEA data from the GPS comes in the Arduino’s serial port and winds up on the SD Card.

Frozen Time Photography with a 100W LED
http://hackaday.com/2015/10/05/frozen-time-photography-with-a-100w-led/
High speed photography is fun. Ultra high frame rate video, even more so. But since not many of us have access to $10,000 HFR cameras… we have to make do with long exposure shots a perfectly timed camera flash. You can design a system to trigger the flash at just the right millisecond — but they’re still pretty expensive typically.
[Electronupdate] has a 100W LED module and penchant for Arduino Nanos — so he wondered if he could make an affordable high speed camera rig — and he did.
Frozen Time Photography and a Super Bright LED module
http://electronupdate.blogspot.ca/2015/10/frozen-time-photography-and-super.html
a bright light source is flashed right at the time desired. Normally this light is from an Xeon flash tube (commonly found in camera flashes).
I was looking at my 100W LED module and I was wondering if it could act as a substitue… while not as bright as an Xeon tube it’s far more controllable in regards to light pulse duration and inter-pulse control.

Toy Television’s Dreams Come True
http://hackaday.com/2015/10/21/toy-televisions-dreams-come-true/
A couple of years ago, [Alec]’s boss brought him a souvenir from Mexico City—a small mid-century console television made of scrap wood and cardboard. It’s probably meant to be a picture frame, but [Alec] was determined to give it a better life.
As it turns out, the screen of [Alec]’s old Samsung I9000 was a perfect fit for the cabinet with room to spare. It was on its way to becoming a real (YouTube) TV once [Alec] could find a way to control it remotely.
There’s enough room inside the remote for a non-LE Bluefruit module,
Trouble is, Bluefruit doesn’t support matrix keypads, so [Alec] used a bare ATMega328 running on the internal clock.
Tiny TV
http://cassettepunk.com/blog/2015/10/16/tiny-tv/
I’ve been having fun building things with bare-bones ATMega328 chips. This is the same chip as the Arduino uses, but pulled from the board and configured to use its own internal clock source. Building things this way results in an impossibly small parts list
That’s right, not a single component beyond the necessities. A keypad, a battery, the controller chip, and the BlueFruit board.

Teach An ATTiny 85 To Swear
http://hackaday.com/2015/10/21/teach-an-attiny-85-to-swear/
Let’s be honest here: one of the first things we all did when we came across speech synthesizers like the Speak-n-spell was to try swear words. [Alec Smecher] has taken this to heart, building a simple buzzer mechanism driven by an ATTiny 85 that swears repeatedly when you connect it. It is a rather simple project (or, as [Alec] himself says, it is “a satisfyingly minimalist build”), but it is quite nicely done.
The 8kHz speech sample (taken from Google Translate) is stored in the code, and written out to one of the PWM outputs of the ATTiny85 from a timing loop to directly drive the small speaker.

Leap Motion Wirelessly Controlling a Prosthetic Hand With an Arduino

The Leap Motion controller is a rather impressive little sensor bar that is capable of generating a massive 3D point cloud and recognizing hands and fingers to allow for gesture control based computing. It’s been out for a few years now but we haven’t seen many hackers playing with it
This time around he’s opted to use the ESP8266 WiFi module instead of a Bluetooth one. He printed off a Raptor hand (from the wonderful folks at e-NABLE) and hooked it up with some RC servos to give him a nice robotic hand to control.

Swimming Pool Dance Floor Enlightened With Leds

In a well documented blog entry, [Loren Bufanu] presents a project that lit up a glass dance floor covering a swimming pool with RGB strips.
The project took around 450 meters of RGB strips controlled by two Rainbowduinos and driven by sixty-four power Mosfets, sixty-four bipolar transistors, and a few other components. Running just the white LEDs draws 8 amps of power.
The Rainbowduino is an ATmega328 Arduino compatible board with two MY9221 controllers. Each controller handles 12 channels of Adaptive Pulse Density Modulation.

Low-Cost, Arduino-Compatible Drawing Robot
http://hackaday.com/2015/10/24/low-cost-arduino-compatible-drawing-robot/
Bringing women into technical education at times seems to be an insurmountable challenge. As a counter, a small drawing robot created by [MakersBox] might help. The robot was used in a ChickTech workshop for teen girls.
The goals for the robot were to have an easy to build, easy to program robot that did something interesting, and was also low-cost so the workshop participants could take it home and continue to learn. These requirements led [MakersBox] to the Adafruit Pro Trinket 3V, stepper motors for accuracy, and a 3d printed chassis to allow for customization.

Internet-connected monitoring with Arduino & GPRS
https://hackaday.io/project/8150-internet-connected-monitoring-with-arduino-gprs
An Arduino-based device connected to the interwebs by GPRS to monitor and log events online using Carriots and Google Sheets
The hardware is almost entirely made of off-the-shelf components. Namely:
* An Arduino Duemilanova.
* A Sim900-based GRPS Arduino shield from Ebay.
* A USB charger (rated 1 A just in case).
* A more few bits and bobs to put everything together (a piece of perfboard, few wires and a plastic case from the junk)
To log the state of the pump online, I used a service called Carriots, that listens for POST data submissions and stores them in a database. Later I made Carriots forward the data to an online form that stores it in Google Sheets so I can post-process it to create graphs.

Instead of optimizing the electronics, I am using a “jumper wires & breakout boards” plan so that any major component can be replaced by several others. This provides physical layout flexibility and avoids component dependencies.

Escape Cable Hell with an Audio I/O Multiplexer
http://hackaday.com/2015/11/02/escape-cable-hell-with-a-multi-io-audio-multiplexer/
If you ever find yourself swapping between a mix of audio inputs and outputs and get tired of plugging cables all the time, check out [winslomb]’s audio multiplexer with integrated amplifier. The device can take any one of four audio inputs, pass the signal through an amplifier, and send it to any one of four outputs.
The audio amplifier has a volume control, and the inputs and outputs can be selected via button presses. An Arduino Pro Mini takes care of switching the relays based on the button presses. On the input side, you can plug in devices like a phone, TV, digital audio player or a computer. The output can be fed to speakers, headsets or earphones.
Switching between inputs or outputs is handled by a bank of TLP172A solid state relays with MOSFET outputs, and it’s all tied together with a micro-controller, allowing for WiFi or BLE functionality to be added on later.
The GitHub repository contains all the hardware and software sources

The Robot Light Switch
http://hackaday.com/2015/11/06/the-robot-light-switch/
Automating your home is an awesome endeavor — but playing with mains AC can be risky business if you don’t know what you’re doing. So why not play it safe and make use of your light switch?
Admittedly, it wasn’t because [Tyler Bletsch] didn’t want to mess around with AC directly, but rather out of necessity.
AC power control without touching AC power
http://discspace.org/easy-servo-control-of-wall-switch-gives-ac-automation/
In this article I’ll show a simple 3D design for a servo mount to control a light switch for about $3, plus some electronics to drive it with a neat little interface. This article explains how I used it to regulate my air conditioner, but the basic bracket allows control of any U.S. standard wall switch.
First, I designed a simple bracket in SketchUp to be 3D printed. It uses the normal lightswitch faceplate screws to hold a cheap 9g servo next to the switch to flip it on command.
The screws go into slots, which allow you to fine-tune the location of the servo. The horn on the servo is the straight kind (===O===), which will be perfectly vertical when not flipping the switch. This means you can still totally use the switch normally without interference. The servo can turn -90 or +90 degrees to hit the switch on command.
To run it, I got an Arduino Nano, a small OLED display, and some tactile buttons to form a user interface.
I also got an early version to work with an ESP8266 programmed with Arduino
This means that you could slap this servo bracket on to any light switch to get web-enabled control almost immediately. The downsides include web security and the need for both 3.3V and 5V supply

Electronic float valve keeps the horse’s feet dry
http://hackaday.com/2015/11/05/electronic-float-valve/
[Bob] built this simple device that can best be described as an electronic float valve. He was wasting a lot of water from overflowing water troughs and buckets around his farm.
The electronics is unabashedly minimal. An ATtiny85 controls a relay via a common variety NPN transistor. The relay in turn switches the solenoid valve. A push-button tells the microcontroller to start the water flowing, and when the water level gets high enough that it touches two hose clamps, the micro shuts it off again.

The Simplest Smart Glasses Concept

IK lets you specify where you want the head of the arm to be placed, and it works out all the movements needed to get it there. This makes it much easier to control than if you were trying to work out each motor movement yourself.

For those that don’t know [Akiba], he’s the guy behind Wrecking Crew Orchestra (TRON Dance) and their EL wire costumes. [Akiba] hacks on his projects at Hacker farm out in rural Japan.
In the tutorial, he sets up a simple 6 LED circuit on a Fredboard (an Arduino compatible board with integrated breadboard). [Akiba] then describes configuring the Vixen sequencer software to control the Arduino, providing simple example code to decode the Vixen serial protocol. Finally [Akiba] shows how to use the ChibiArduino protocol stack to build a wireless illumination system.

Laser Galvo: Arduino Controlled
Using an Arduino and a pair of servos to create a laser show on a sheet of luminous vinyl.
https://hackaday.io/project/8524-laser-galvo-arduino-controlled
UV laser pens leave a luminescent trail when shone on glow-in-the-dark material. In this project a 405nm laser beam is steered by a pair of Arduino controlled mirrors leaving a sine wave based trace on a sheet of luminous vinyl.

Physical Fitness for the Truly Lazy
http://hackaday.com/2015/11/21/physical-fitness-for-the-truly-lazy/
We know we should go on and do some push ups today. Of course, we are a lazy bunch, so not everyone’s going to do a full push up. Then we’ll all argue how many we actually did. If this sounds like you, maybe you need an Arduino-based project that counts proper push ups.
Project designer [jckelley] made use of some Grove sensors (the Seeed Studio system to plug many types of sensors and other devices into an Arduino) to connect an infrared sensor to an Arduino-pin compatible computer (a LinkIt, which is an ARM-based platform, also from Seeed).

Control Your HTPC With Scavenged IR Parts
http://hackaday.com/2015/11/22/control-your-htpc-with-scavenged-ir-parts/
If you’ve built yourself a home theater PC, one of your highest priorities is probably coming up with a convenient control solution. The easiest way to do this is to simply use something like a wireless keyboard and mouse. But, that’s not very conducive to an enjoyable home theater experience, and it feels pretty clunky. However, if you’ve got the right components lying around, [Sebastian Goscik] has instructions and an Arduino sketch that will let you control your HTPC with any IR remote control.
[Sebastian’s] setup can be replicated with things you probably have on hand: an Arduino, an IR remote, and a scavenged IR receiver.
It starts with an Arduino Sketch that lets you can see on the serial monitor what code is being generated by the button presses on your remote. These are then scripted to perform any task or function you like when those buttons are pushed

USB Volume Control
http://hackaday.com/2015/11/22/usb-volume-control/
If you buy expensive computer speakers, they often have a volume knob you can mount somewhere on your desk so you aren’t dependent on the onboard volume control. [Kris S] decided to build his own version of the remote volume control. Not surprisingly, it uses an Arduino-compatible Digispark board and a rotary controller. The Digispark (that [Kris S] bought for $2) is compatible with the Adafruit Trinket. This is key because the Trinket libraries are what make it easy to send media keys over the USB (using the HID interface) to control the volume.
Simple DIY Volume Control Knob!
http://www.instructables.com/id/Digispark-Volume-Control/
Got a desktop with a sound system far from where you sit?–I do. After a bit of digging, I found that it was pretty easy to make my own soft volume control knob on the cheap.
In this tutorial I will show you how to create a USB volume control knob for your PC!
To keep things simple, Instead of Arduino, I will use an arduino compatible board called the Digispark. Not only is the Digispark small, but it is cheap! Normally I pick mine up from aliexpress.com for less than $2 USD

Defeating Chip and PIN With Bits of Wire
http://hackaday.com/2015/11/25/defeating-chip-and-pin-with-bits-of-wire/
One of many ways that Americans are ridiculed by the rest of the world is that they don’t have chip and PIN on their credit cards yet; US credit card companies have been slow to bring this technology to millions of POS terminals across the country. Making the transition isn’t easy because until the transition is complete, the machines have to accept both magnetic stripes and chip and PIN.
This device can disable chip and PIN, wirelessly, by forcing the downgrade to magstripe. [Samy Kamkar] created the MagSpoof to explore the binary patterns on the magnetic stripe of his AmEx card, and in the process also created a device that works with drivers licenses, hotel room keys, and parking meters.
The electronics for the MagSpoof are incredibly simple. Of course a small microcontroller is necessary for this build, and for the MagSpoof, [Samy] used the ATtiny85 for the ‘larger’ version (still less than an inch square). A smaller, credit card-sized version used an ATtiny10. The rest of the schematic is just an H-bridge and a coil of magnet wire – easy enough for anyone with a soldering iron to put together on some perfboard.

This VU Meter is Built Into the Speaker
http://hackaday.com/2015/11/29/this-vu-meter-is-built-into-the-speaker/
He started with a pair of speakers he had and picked up some NeoPixel LED strips
To control the LEDs, he’s using an Arduino Uno (Atmega328p) which measures the audio level in order to modulate the LED output. A bit of software later (shared on GitHub if you’re interested!) and the VU meters were ready for action

Basic Toolkit for the Basement Biohacker
http://hackaday.com/2015/11/27/basic-toolkit-for-the-basement-biohacker/
Taking the form of an Arduino mega-shield that supports a pH meter, a spectrophotometer, and a PID-controlled hot plate, [M. Bindhammer]’s design has a nice cross-section of the instruments needed to start biohacking in your basement. Since the shield piggybacks on an Arduino, all the data can be logged, and decisions can be made based on the data as it is collected.
