The Memento Mori installation consists of a 4 digit LED display, which is mounted between the teeth of a casted human skull and connected to a highly accurate rubidium atomic clock. The display visualizes the passage of time by repeatedly counting down one second in millisecond-steps (from 1.000 to .001).
By utilizing atomic clocks, we can determine with unimaginable accuracy how quickly the irretrievable essence of our lives is decreasing, how fast the ultimate yet unknown point in time of our death is approaching – millisecond by millisecond. This Memento Mori is not only an ironic reminder of our own mortality but a reflection of the values we are striving for. Despite all the hyper-accurate technology inhabiting our lives the haunting question of “When?” still remains unanswered.

Often times an office finds the struggle of granting access to rooms without jeopardizing physical copies of keys. These struggles can be easily overcome with technologies such as facial recognition, finger print recognition, bar codes, radio frequency identification, and much more.
Here at I Heart Engineering, we felt the need to have awesome badges fit our daily attire, where we can have both style and access to our offices without the need of weighty keys by building a robot door.
The PN532 is the most popular NFC chip, and is what is embedded in pretty much every phone or device that does NFC. It can pretty much do it all, such as read and write to tags and cards, communicate with phones (say for payment processing), and ‘act’ like a NFC tag. If you want to do any sort of embedded NFC work, this is the chip you’ll want to use!
Adafruit NeoPixel Digital RGB LED Weatherproof Strip 60 LED – 1m – You thought it couldn’t get better than our world-famous 32-LED-per-meter Digital LED strip but we will prove you wrong! You wanted twice the LEDs? We got it (well, its 1.875 times as many but that’s within a margin of error). You wanted thinner strips? Now only 12.5 mm wide, 10 mm if you remove the strip from the casing. You wanted less noticable strip color – this strip has white-colored flex PCB, which will be less visible against white-painted walls.
I remade my fox ears for Neko Nation yesterday and put heaps of LEDs in them! They can do rainbows!
Laithorn asked if I’d put up schematics for my LED fox ears. Here goes! It’s a bunch of Adafruit Flora Pixels hot glued to a black plastic headband I found in a dollar shop. I wired them directly up to a Digispark (tiny arduino thing) which is powered from a 9v battery in my pocket. Flora Pixels need only one data wire, so you can power them through regular stereo audio cables which are strong, plentiful, comfortable and asthetic, and you can use audio splitters to hook multiple things up in parallel.
Flora RGB Smart Neo Pixel version 2 – Pack of 4 – What’s a wearable project without LEDs? Our favorite part of the Flora platform is these tiny smart pixels. Designed specifically for wearables, these updated Flora NeoPixels have ultra-cool technology: these ultra-bright LEDs have a constant-current driver cooked right into the LED package! The pixels are chainable – so you only need 1 pin/wire to control as many LEDs as you like. They’re easy to sew, and the chainable design means no crossed threads.
Awww, You make me blush. Wouldn’t it be cool to animate your Adafruit Circuit Playground electronic component plushie? I have Ruby the Red LED plushie. I wanted it to light up and have it respond to sound. Here is an easy mod to get that done. Sorry, no lasers this time.
Probably wouldn’t really be considered old-school soft circuits but probably more of a hybrid, electronics in a softshell case. I still have a bobbin of conductive thread I need to do something with. Note that this was a first attempt in trying to do a mod with stuff I had on hand but I will offer suggestions on what you should do to get a more satisfactory result.
Still trying to solidify that reputation as the office Grinch? This project will let everyone know you’re a complete jerk in no time. It’s called the 8-bit Annoying Person Remover. It detects when someone enters your office at which point it starts to play the Super Mario Bros. theme song while the display counts down 400 seconds. Just like in the game the music gets faster at the end and when it stops they know it’s time to get the heck out.
The hardware inside isn’t too complicated. An Arduino and a Wave shield do most of the work. The song played is stored on an SD card and can easily be changed. There’s a speaker mounted under the top heat vent of the enclosure. The device defaults to displaying the time of day, but monitors a motion sensor on one side to detect when someone comes through the door. This also works when someone leaves, cutting off the music and resetting the display.
Over the past year I’ve been working on my first big hardware project. It started as an experiment in powering and controlling led displays. I love the blinky lights and wanted something big that would catch the eye.
The end result is a tabletop sized arcade for a 4×4 lights out game similar in gameplay to the Mini Lights out Game by Tiger Electronics.

This project took me a long while to complete due to lack of free time. I began when my son turned one year old and finished not long before he turned two. The effort paid off though and I’m happy with how it turned out.
RGB Pixels are digitally-controllable lights you can set to any color, or animate. Each RGB LED and controller chip is molded into a ‘dot’ of silicone. The dots are weatherproof and rugged. There are four flanges molded in so that you can ‘push’ them into a 12mm drill hole in any material up to 1.5mm/0.06″ thick. They’re typically used to make outdoor signs. We also have flat-backed pixels that are essentially the same, but are not as long and thin.
This project details an open-source colorimeter, which is made from open source electronics and 3-D printable components. This is part of a larger project to reduce the cost of scientific equipment using open-source hardware.
Colorimetric analytical methods are likely to be the most commonly applied methods for determining the concentration of dissolved species. Many dissolved species absorb light of a particular wavelength and the amount absorbed as the light passes through a given length of solution increases with increasing concentration the species; higher concentrations absorb more light than do lower concentrations. The relationship between absorption and concentration is defined by the Beer-Lambert law:http://en.wikipedia.org/wiki/Beer-Lambert.
A colorimeter or a spectrophotometer is employed to measure absorption at a specific wavelength. Light is usually filtered to permit only a narrow band of light at the absorbance peak wavelength for the species measured. The apparatus typically reports results in concentration units but also reports absorbance units or transmittance.
This new Adafruit shield makes it easy to use a 16×2 Character LCD. We really like the Blue & White 16×2 LCDs we stock in the shop. Unfortunately, these LCDs do require quite a few digital pins, 6 to control the LCD and then another pin to control the backlight for a total of 7 pins. That’s almost half of the pins available on a classic Arduino! With this in mind, we wanted to make it easier for people to get these LCD into their projects so we devised a shield that lets you control a 16×2 Character LCD, up to 3 backlight pins AND 5 keypad pins using only the two I2C pins on the Arduino!
I wanted to share my Valentine’s Day project with you. I called it a Valentine Love Light and it’s a gift I made for my wife incorporating an animated LED message along with a light bulb which has the filament replaced with an EL-wire heart. By the way, your tutorials for EL wire are really helpful – the use of copper tape makes working with it so much easier!
