The buzzer on a washer or dryer may be OK for most people, but what if you would like something a little more versatile to tell you when your laundry is done? Here’s an interesting solution involving an Arduino Yún that sends a text message when the washer or dryer […]
Pets are people too. If corporations can be labeled as people then why can’t our pets? Regardless, when it comes to our pets, we often spoil them with lavish gifts to show our affections. Makers on the other hand tend to build projects that help with everything from feeding […]
[Connor] was working on a project for his college manufacturing class when he came up with the idea for this sleek desk lamp. As a college student, he’s not fond of having his papers glowing brightly in front of him at night. This lamp takes care of the problem by adjusting the color temperature based on the position of the sun. It also contains a capacities touch sensor to adjust the brightness without the need for buttons with moving parts.
The base is made from two sheets of aluminum and a bar of aluminum. These were cut and milled to the final shape. [Connor] found a nice DC barrel jack from Jameco that fits nicely with this design. The head of the lamp was made from another piece of aluminum bar stock. All of the aluminum pieces are held together with brass screws.
A slot was milled out of the bottom of the head-piece to make room for an LED strip and a piece of 1/8″ acrylic. This piece of acrylic acts as a light diffuser. Another piece of acrylic was cut and added to the bottom of the base of the lamp. This makes for a nice glowing outline around the bottom that gives it an almost futuristic look.
The capacitive touch sensor is a pretty simple circuit. [Connor] used the Arduino capacitive touch sensor library to make his life a bit easier. The electronic circuit really only requires a single resistor between two Arduino pins. One of the pins is also attached to the aluminum body of the lamp. Now simply touching the lamp body allows [Connor] to adjust the brightness of the lamp.
[Connor] ended up using an Electric Imp to track the sun. The Imp uses the wunderground API to connect to the weather site and track the sun’s location. In the earlier parts of the day, the LED colors are cooler and have more blues. In the evening when the sun is setting or has already set, the lights turn more red and warm. This is easier on the eyes when you are hunched over your desk studying for your next exam. The end result is not only functional, but also looks like something you might find at that fancy gadget store in your local shopping mall.
Despite the MicroView shipping a ton of units, we haven’t seen many projects using this tiny Arduino and OLED display in a project. Never fear, because embedded systems engineer, podcaster, and Hackaday Prize judge [Elecia White] is here with a wearable build for this very small, very cool device.
The size and shape of the MicroView just cried out to be made into a ring, and for that, [Elicia] is using air-drying bendy polymer clay. To attach the clay to the MicroView, [Elecia] put some female headers in a breadboard, and molded the clay over them into a ring shape. It works, and although [Elecia] didn’t do anything too tricky with the headers and clay, there are some interesting things you could do running wires through the clay.
What does this ring do? It’s a Magic 8 Ball, a game of Pong controlled by an accelerometer, a word-of-the-day thing (with definitions), all stuffed into a brass silicon, OLED, and clay knuckle. Video below.

One day, [Samy]’s best friend [Matt] mentioned he had a wireless doorbell. Astonishing. Even more amazing is the fact that anyone can buy a software defined radio for $20, a small radio module from eBay for $4, and a GSM breakout board for $40. Connect these pieces together, and you have a device that can ring [Matt]’s doorbell from anywhere on the planet. Yes, it’s the ultimate over-engineered ding dong ditch, and a great example of how far you can take practical jokes if you know which end of a soldering iron to pick up.
Simply knowing [Matt] has a wireless doorbell is not enough; [Samy] needed to know the frequency, the modulation scheme, and what the doorbell was sending. Some of this information can be found by looking up the FCC ID, but [Samy] found a better way. When [Matt] was out of his house, [Samy] simply rang the doorbell a bunch of times while looking at the waterfall plot with an RTL-SDR TV tuner. There are a few common frequencies tiny, cheap remote controls will commonly use – 315 MHz, 433 MHz, and 900 MHz. Eventually, [Samy] found the frequency the doorbell was transmitting at – 433.8 MHz.
After capturing the radio signal from the doorbell, [Samy] looked at the audio waveform in Audacity. It looked like this doorbell used On-Off Keying, or just turning the radio on for a binary ‘1’ and off for a binary ‘0’. In Audacity, everything the doorbell transmits becomes crystal clear, and with a $4 434 MHz transmitter from SparkFun, [Samy] can replicate the output of the doorbell.
For the rest of the build, [Samy] is using a mini GSM cellular breakout board from Adafruit. This module listens for any text message containing the word ‘doorbell’ and sends a signal to an Arduino. The Arduino then sends out the doorbell code with the transmitter. It’s evil, and extraordinarily over-engineered.
Right now, the ding dong ditch project is set up somewhere across the street from [Matt]’s house. The device reportedly works great, and hopefully hasn’t been abused too much. Video below.

Using a 3d printer means playing with some hardware but especially some softwares. In the tutorial of this week, the fourth tutorial of our series , Kris is going to introduce you how to work with Slic3r, a G-Code generator for 3d printers and basically a tool you need to convert a digital 3D model into printing instructions for your 3D printer. Slic3r is an open source software able to cut the model into horizontal slices (layers), generates toolpaths to fill them and calculates the amount of material to be extruded so that you can reach good results.
The object you’ll be able to print with your Materia 101 is a pirate hook !
Follow the 12 steps on Scuola and print yours >>

Dmitry Morozov shared with us a new interactive installation called Solarman at the Polytech Museum in Moscow. 2014 and It’s a work he created with Julia Borovaya and Edward Rakhmanov using 64 ultra bright LEDs, 12-channel sound system and 8 electrical nerve stimulation electrodes controlled by Arduino Mega :
Data on power of X-radiation flux from the Sun is received in real time from the satellite GOES15 which is tracking solar activity. It is being converted into streams of sound, light and electric discharges, thus allowing a spectator to experience in more intensive and evident way the influence of the main luminary of the solar system.
The data, which is measured in watts per square meter, come with a frequency of once per minute. A special computer algorithm transforms it in sound waves, distributed by 12 channels in the space. The radiation power directly controls the height of tones and spectral changes in the sound. The speed of sound displacement in the space is also dependent on these parameters. Light is generated by algorithmic transformation of X-ray emission into physical modeling of light particles, which also affect the muscle stimulators in the chair to produce weak electric discharges.
