Why Build Furniture When you can Grow it?

[Gavin Munro] is turning the standard paradigm of furniture making on its head. Instead of harvesting trees and slicing them up into boards – or worse, turning them into sawdust to be used for particle board – [Gavin] is literally growing furniture.

Supple young willow saplings are pruned and trained using wire and plastic form work. The trees are encouraged to grow in the right directions to form legs, arms, seat and back, and eventually the individual pieces are grafted Fg_3_chairs_growingtogether to continue growing into one solid piece. When the chair is mature, the leaves are removed, the chair is cut free from the ground, and with a little seasoning and finishing, you’ve got a unique and functional chair. And what’s more, since it’s a solid piece of wood, there are no joints to loosen over time.

You’ve got to admire the dedication that goes into these chairs. The current crop is about nine years old and still a few years from harvest. There’s a lot to be learned from the organization of a project like this – planning a production line where the first finished pieces are a decade or more from the showroom is no mean feat. Looks like [Gavin] has thought that through as well, by starting a line of lamps that will be turning a profit sooner. The video after the break demonstrates not only [Gavin’s] chairs and lamps, but also features his first harvest of tables.

Increasing The Brightness Of A Philips LivingColors Lamp

[Martin] recently purchased a Philips LivingColors lamp. It’s a commercial product that basically acts as mood lighting with the ability to change to many different colors. [Martin] was disappointed with the brightness of his off-the-shelf lamp. Rather than spend a few hundred dollars to purchase more lamps, he decided to modify the one he already had.

[Martin] started by removing the front cover of his lamp. He found that there were four bright LEDs inside. Two red, one green, and one blue. [Martin] soldered one wire to the driver of each LED. These wires then connected to four different N-channel MOSFET transistors on a piece of protoboard.

After hooking up his RIGOL oscilloscope, [Martin] was able to see that each LED was driven with a pulse width modulated signal. All he had to do was connect a simple non-addressable RGB LED strip and a power source to his new driver board. Now the lamp can control the LED strip along with the internal LEDs. This greatly extends the brightness of the lamp with minimal modifications to the commercial product. Be sure to check out the video below for a complete walk through.

Flat Pack Elastic Band Lamp is a Thing of Beauty

[Matt] was looking for a project for his senior industrial design studio at Wentworth Institute of Technology. He ended up designing a clever lamp that can be flat packed. [Matt] started by drawing out designs on paper. He really liked the idea of combining curves with straight lines, but he wanted to translate his two-dimensional drawings into a three-dimensional shape.

zOz0ys6 - ImgurHaving access to a laser cutter made the job much easier than it could have been and allowed [Matt] to go through many designs for the lamp frame. The two main pieces were cut from acrylic and include mounting pegs for the elastic bands. The two plastic pieces are designed to slot together, forming a sort of diamond shape.

The final version of the lamp required that the elastic bands had holes punched in them for mounting. The holes were placed over the small pegs to keep the bands in place. [Matt] used 3/4″ industrial elastic bands for this project. He then used a 120V 15W candelabra light bulb to illuminate the lamp. The final design is not only beautiful, but it can be flat packed and manufactured inexpensively.

Absolute Overkill IKEA Lampan Lamp Hack

Sometimes too much overkill isn’t enough. [Jesus Echavarria] hacked an IKEA Lampan light for his daughter to add color LEDs, a timer, Bluetooth control over the hue, and a local override knob. The result: a $5 lamp with at least $50 of added awesomeness. Let’s have a look at the latter.

The whole lamp system is based around a PIC microcontroller and WS2811 LEDs for the color light show. Since the lamp was already built to run a 40W lightbulb, and [Jesus] wanted to retain that functionality, he added an SSR to the build. Yeah, it’s rated for 5,000W, but it’s what he had on hand.

Top-ElementsNext comes the low-voltage power supply. [Jesus] needed 5V for the PIC, and used the guts from a cheap USB charger as a quick and dirty 5V converter — a nice hack. To power the HC-05 Bluetooth module, which requires 3.3V, he wired up a low-dropout voltage regulator to the 5V line. A level-converter IC (74LVC07) gets the logic voltage levels straight between the two.

A fuse for the high-voltage power line, screw-terminal connectors all around, and a potentiometer for manual override round out the hardware build.

On the software side, [Jesus] set up the knob to turn on and off the built-in lamp as well as control the colors of the LED ring. That’s a nice touch for when his daughter wants to change the lamp’s color, but doesn’t want to go find her cellphone. But when she does, the SPP Pro app sets the colors by sending pre-programmed serial commands over Bluetooth to the PIC in the lamp.

All in all, a nice build, well-documented, and with enough rough edges that none of you out there can say it’s not a hack. Nice job [Jesus]! We can’t wait to see what he does next… robot lamp anyone?

Articulated Computer Lamp Lights up your life

[Samimy] raided his parts bin to build this articulated lamp (YouTube link) for his computer workstation. Two pieces of aluminum angle form the main body of the lamp. Several brackets are used to form two hinges which allow the lamp to be positioned above [Samimy’s] monitor. The light in this case comes from a pair of 4 watt LED bulbs.

[Samimy] used double nuts on the moving parts to make sure nothing comes loose. The outer nuts are acorns, which ensure no one will get cut on an exposed bit of threaded rod. [Samimy] wired the two bulbs up in a proper parallel mains circuit. The switch is a simple toggle mounted in a piece of Plexiglass on the end of the lamp.

One thing we would like to see on this build is a ground wire. With all that exposed aluminum and steel, one loose connection or worn bit of insulation could make the entire lamp body live.

Use A Lamp To See Into The Future

We’ve heard of magic lamps before, but this one is actually real. [Alex] has created a wall-mounted lamp that can tell you what the future will be like; at least as far as the weather is concerned. It is appropriately named “Project Aladdin” and allows you to tell a great deal about the weather at a glance as you walk out of the door.

The lamp consists of twelve LED strips arranged vertically. The bottom strip represents the current hour, and each strip above represents another hour in the future. The color of each strip indicates the temperature, and various animations of the LEDs within each strip indicate wind speed and precipitation.

The system uses a weather forecasting backend built-in Java, which is available on the project’s page. The LEDs are controlled by an application that is written in C, and the entire set of LEDs are enclosed in a translucent housing which gives it a very professional appearance. Be sure to check out the demo video after the break. Be sure to check out some other takes on weather lamps which use regular desk lamps instead of intricate scratch-made LED lamps.

Prefix Your Phone Alarm with a Desk Lamp

If you are like [Gbola], then you have a hard time waking up during the winter months. Something about the fact that it’s still dark outside just makes it that much more difficult to get out of bed. [Gbola] decided to build his own solution to this problem, by gradually waking himself up with an electric light. He was able to do this using all off-the-shelf components and a bit of playing around with the Tasker Android application.

[Gbola] started out with a standard desk lamp. He replaced the light bulb with a larger bulb that simulates the color temperature of natural daylight. He then switched the lamp on and plugged it into a WeMo power switch module. A WeMo is a commercial product that attempts to make home automation accessible for consumers. This particular module allows [Gbola] to control the power to his desk lamp using his smart phone.

[Gbola] mentions that the official WeMo Android application is slow and includes no integration with Tasker. He instead decided to use the third-party WeMoWay application, which does include Tasker support. Tasker is a separate Android application that allows you to configure your device to perform a set task or series of tasks based on a context. For example you might turn your phone to silent mode when your GPS signal shows you are at work. WeMoWay allows [Gbola] to interact with his WeMo device based on any parameter he configures.

On top of all of that, [Gbola] also had to install three Tasker plugins. These were AutoAlarm, Taskkill, and WiFi Connect. He then got to work with Tasker. He configured a custom task to identify when the next alarm was configured on the phone. It then sets two custom variables, one for 20 minutes before the alarm (turn on the lamp) and one for 10 minutes after (turn it off).

[Gbola] then built a second task to actually control the lamp. This task first disconnects and reconnects to the WiFi network. [Gbola] found that the WeMoWay application is buggy and this “WiFi reset” helps to make it more reliable. It then kills the WeMoWay app and restarts it. Finally, it executes the command to toggle the state of the lamp. The project page has detailed instructions in case anyone wants to duplicate this. It seems like a relatively painless way to build your own solution for less than the cost of a specialized alarm clock lamp.
