Rotary Telephone Becomes Stylish Lamp

The vintage aesthetic is more popular than ever, and while things like rotary phones aren’t particularly useful anymore, there’s a lot of fun to be had using them in new and inventive ways. For this project, [Sander] built an attractive table lamp out of a Siemens rotary phone.

Switched off, the lamp appears to be nothing more than a phone with its handset floating in midair. However turn the dial, and LEDs mounted in the receiver begin to glow. Taking things a step further as good hackers do, [Sander] used a motorised potentiometer to control the LED brightness with a NodeMCU board featuring the ESP8266. This allows the LEDs to be dimmed either by hand, or by a smartphone connected over WiFi, without the dial getting out of sync.

By using a dual H-bridge setup, the NodeMCU is able to both control the motorized pot as well as generate an AC signal to activate the original bell in the phone, which adds a whole lot of nostalgia points. Fitting the motorized pot into the phone did lend some challenges but that didn’t slow [Sander] down – they simply used a cheap universal joint to allow the motor to connect to the rotary dial off-axis. A great trick to keep in your back pocket.

For the haunting floating effect, [Sander] used a meter of 4 mm brass rod, bending it into shape to hold up the handset. This was used as a ground, and along with a couple of extra wires for power, was covered in a black textile sheath recovered from another electrical cable. [Sander] tells us it wasn’t the easiest thing to pull off, but we definitely agree that the effect is totally worth it.

Ikea Desk Lamp That Will Defend Your Lungs

While some people may enjoy the occasional whiff of noxious smells — gasoline, axe body spray, etc — prolonged exposure to fumes is not good for your health. This goes for soldering too, isn’t it about time you added some abatement to your bench tools?

Inspired by some of the fume hoods we’ve featured before — take note, ye who art lacking projects — [Georg Sluyterman] put together his own Ikea lamp fume extractor.

The most striking feature is that it’s mounted on an Ikea desk lamp making for convenient positioning and minimal clutter. A NeoPixels strip lights up your soldering space while the PIR sensor activates the fan when it detects movement. A WeMos D1 Mini is included for WiFi connectivity but that feature still down the road a little bit. The functionality that is in place is still quite impressive; more on that after the break.

Bamboo Plant Becomes A Stylish Light Switch

If flipping a regular old light switch or pressing buttons isn’t an adequately pleasing way to use your appliances around the house, how about poking at the leaves of a plant to turn on your lamp? [Xkitz] has provided a thorough breakdown of how to turn any conductive object in your living space into a nifty capacitive touch switch that adds a bit of charm to such an everyday action.

Creating an electrostatic field around a conductive medium, the capacitive touch relay constantly monitors this field and will toggle when any minuscule change to the capacitance is detected. [Xkitz] uses a bamboo plant as his trigger. Gently touching any leaf will still act as an adequate trigger — as cool demonstration of how the electrostatic field works.

Ikea Projection Lamp Makeover Adds LED Matrix and Raspberry Pi Zero

If you’re like us, it’s hard to walk through an Ikea without mentally hacking everything there into something else. The salad bowl? Parabolic antenna. Drawer slides? Linear motion rails. Storage containers? Etching tank. We admit that we still haven’t figured out what to do with that 1,000-pack of tea lights.

[Alain Mauer] pulled off an Ikea hack that we’ve always dreamed about. In particular, he took the Sprida projector lamp and wedged an 8×8 LED matrix and Raspberry Pi Zero into it.

The lamp in question is essentially a slide projector for kids. Before [Alain] got to it, it had an LED in the back, a mount for a slide in the middle, and a focusing lens on the front. His mod is simplicity itself: remove the LED and transparency, and place the LED matrix in the focal plane where the slide used to be. Reverse images on the LED in software to compensate for the lens, and you’re done.

The video says “Raspberry Pi Zero with WiFi” and the project title promises “IoT”, but we don’t see the WiFi in the build. We’re guessing that [Alain] will get around to it — it’s easily doable. (Doh! There’s a tiny USB WiFi dongle providing the obligatory wireless connection.) Anyway, the point is the projection, and we love it, and we’d be lying if we said it didn’t make us think about RGB matrices.

White Oak Illuminated Bluetooth Speaker

Besides being common tools available to most hackers and makers out there, 3D printing, CNC machines, and cheap Chinese electronics have one more things in common: they were all used by [Nick] to build a bluetooth speaker system that has some interesting LED effects built into the case.

This is fresh on the heels of another hack that used similar construction methods to build a “magic” wood lamp. [Nick] takes it a step further, though. His case is precisely machined in white oak and stuffed with the latest China has to offer: a bank of lithium-ion batteries, a DC-DC converter to power the amplifier, and a Bluetooth module. After some sanding, the speakers look professional alongside the blue light features hiding behind the polycarbonate rings.

Of course you’ll want to visit the project site for all the details of how [Nick] built his speaker case. He does admit, however, that the electronics are fairly inefficient and need a little work. All in all though, it’s a very refined set of speakers that’ll look great on a bookshelf or on a beach, workshop bench, or anyplace else that you could take them.

Building an Interactive LED Lamp To Annoy Yourself

[Norwegian Creations] makes things as a business model. Tired of the mundane lamp above their heads, they decided to put their skills to use. The basic idea was simple, plot out a cool 3D function, put some RGB LEDs behind it, make it an awesome mathematical rainbow light display, hang it right above their desks, and then ignore it for their monitors while they worked.

The brains of the project is a Raspberry Pi B+, WS2812 LED strips, and a Fadecandy controller from Adafruit. They 3D printed hexagonal towers out of clear plastic and labeled each carefully. Then they attached the strips to the board, glued on the hexagons, and covered the remaining surface in cotton balls to give it a cloud-like appearance.

The lamp normally plays patterns or maintains a steady light. As the day turns to night it reflects the world outside. However, if someone likes their Facebook page the light has a little one robot strobe party, which we imagine can get annoying over time. Video after the break.

Man Shoots Lamp

What do you get when you mix together all of the stuff that you can get for cheap over eBay with a bit of creativity and some PVC pipe? [Austiwawa] gets a table lamp, remote-controlled by a toy gun, that turns off and falls over when you shoot it. You’ve got to watch the video below the break.

This isn’t a technical hack. Rather it’s a creative use of a bunch of easily available parts, with a little cutting here and snipping there to make it work. For instance, [Austiwawa] took a remote control sender and receiver pair straight off the rack and soldered some wires to extend the LED and fit it inside the toy gun. A relay module controls the lamp, and plugs straight into the Arduino that’s behind everything. Plug and play.

Which is not to say the lamp lacks finesse. We especially like the screw used as an end-of-travel stop for the servo motor, and the nicely fabricated servo bracket made from two Ls. And you can’t beat the fall-over-dead effect. Or can you? Seriously, though, great project [Austiwawa]!
