Arduino-Controlled Robot Brings Pointillism Back!

Friday, August 12th, 2011

[Paul Ferragout] realized a strange printer, with an incorporated program to print any image using a time-based algorithm. According to the grey value of a pixel on an image, the felt pen remains in contact with the blotting paper for relative periods of time.

The Arduino-controlled Time Print Machine uses an algorithm to “paint” images — portraits, still lives, you name it — out of nothing but splotches of ink. Equipped with a felt pen and blotting paper, it works like a CNC-milling machine. Program the machine to render a digital image, and the pen starts stabbing at the paper, varying the amount of time it spends on each dot according to the gray value of the respective pixel; the more time allotted, the more the ink bleeds, and the thicker the dot.

The resulting images can take up to 34 hours to print and look like bad photocopies, each totally unique. We’re not sure whether to think of the Time Print Machine as the world’s least-efficient printer or the world’s most-efficient Pointillist painter. The one thing we know is this: The machine is weirdly hypnotic. We could watch that thing drop ink all afternoon

Steampunk Record Player with Arduino

Friday, August 5th, 2011

A steam-powered record turntable made out of juck & re-used things.

This was made with small steam engine with a boiler crafted from a copper water pipe and carved some wood for the custom platter and base. Add some magnets, a coil for a pickup and a servo that is controlled by Arduino.

Radio Arduino

Thursday, August 4th, 2011

Nice Oscar Belle Two Band Transistor Radio (1960s) hacked with Arduino.

What it is really doing is playing 24 music tracks that I preloaded onto an SD card in WAV format. There are also 10 tuning noises tracks that get played when the tuner is turned.

Because this is the first time I did this I had a lot of help. Firstly the chaps and chapesses at Hackspace have been very supportive in teaching me how to use and Arduino, particularly Adrian McEwan and Oomlout. Also Jingle Joe who supervised my soldering of the Wave Shield, Brox who helped me decipher the ancient mysteries of FAT16 and Esme who helped dismantle the original radio… PS I did do some of it myself!

Stype Typewriter: Chat on Skype With Walternate

Thursday, August 4th, 2011

[Daniel Huhndt] hacked a typewriter to let it sending his dato over Skype: the Stype.

With the help of “some solenoids, relays, pushbuttons, some parts of a cheap keyboard, an arduino mega and a mac mini” , the typewriter can be used to send messages online. Whatever is typed into the paper gets sent, and the replies are automatically typed into the paper, archiving the conversation in the process. Whether our daily conversations are worth documenting is another matter.

See this post to have more typewriters-to-digital world hacks.

Digital Lathe By FabLabItalia (Build Your Own!)

Monday, July 18th, 2011

Some time ago the guys at Fablab Italia in Turin joined a city exhibition of art, design and related. The exhibition is hosted in Vanchiglia, a neighborhood of Turin, and it’s called Vanchiglia Open Lab (LOV). The project they managed to bring to the Open Lab is really interesting: a digital lathe which lets you interact physically with a 3D program and print your own sketch with the 3D printer.

You need 5 potentiometers hooked up to the first five Analog pins of Arduino. 4 of them are used to modify the shape, the fifth is used to change the step & resolution of the shape. An Hoberman-style sphere lets you control the rotation of those 5 pots in a different way.

Wanna try? Donwload project files (Arduino, Blender, Laser Cutter) from Fablab Italia’s Wiki.

Arduino Controlled Dishwasher

Thursday, May 26th, 2011

Arduino Forum User [UnaClocker] shared a cool hack on its Maytag dishwasher:

The control panel on the front of it died, it failed from corrosion getting into the laminated plastic PCB that it’s made up of. Not really repairable, just meant to be replaced, except that it’s a $150 part. From what I could find online, it seems to be a common failure, so why buy an overpriced part that’s just going to fail all over again?This is one of the things I love about the Arduino, it allows me to consider alternatives that I’d have NEVER been able to consider before. If I had to program a controller in assembly, or flat do it with just discrete chips, I’d have never considered this as an option. But with the Arduino, not only can I build my own controller, but it’s almost stupidly simple to do.

Ultimaker Pick & Place

Friday, April 29th, 2011

Nice (mis)use of a Ultimaker 3D printer to act as a pick & place machine.

Assembling medium quantities of PCBs was never within the reach of a home based manufacturer. It requires expensive equipment, but most of these parts can actually be 3D printed, and you can use your existing 3D printer, such as the Ultimaker, to do pick-and-place operations.

Gameboy ROM backups using an Arduino

Wednesday, March 23rd, 2011

[Alex] collects retro gaming consoles. One day while playing a SNES title, his save games got wiped when he powered off the system. It turned out that the battery inside the game cartridge got disconnected somehow, and it got him thinking. He decided he wanted to find a way to back up his save games from the cartridges for safe keeping.

While cart readers exist, he says that they are hard to find nowadays, so he decided to construct his own using an Arduino. SNES cartridges are relatively complex, so he opted to focus on Gameboy cartridges for the time being. Before attempting to back up save games, he first chose to learn how to communicate with the cartridges in general, by reading the ROM.

Illutron Ship Gets Remote-Controlled

Friday, March 11th, 2011

[Christian] from Illutron hackespace in Copenhagen managed to control and monitor this ship (Illutron) from the internet.

Today, it is finally possible to remotely monitor the ship. In essence: I am sitting in the warm comfort of my home, and with a glance at my phone, I can see, that the sinking alarm in the machinery room is dry. The light is out in the Mess room. All is nice at our little lovely ship out there in the dark, cold Sydhavn.
Actually, behind this lies a pretty clever system (I think I am allowed to brag a little :-), that makes it possible to monitor events on sensors on the ship, and trigger that messages is sent to Google
Talk users. (if you have a gmail, you have Google Talk) It is also possible via your chat, to send commands to the ship, and get reading from sensors when you want them.[...] Basicly, we can monitor anything, that can be plugged into an Arduino board. One thing I would love, is a temperature sensor for the Mess room. Bring the sensor, and I will mount it So far, we have
– a light sensor, that reports if it is light or dark in the Mess (the electronics room)
– a new water level sensor. I didn’t dare mess with the old system, so I am putting in new float sensors

Things can still be developed a lot, and it will be – Suggestions would be happily received.
Thanks and hello to Stephane and Olle that came by to visit us at the sunday meeting, and ended up staying all evening – for help with sensor mounting and JavaScript improvements!

Kinect Controlled Delta-Robot

Monday, March 7th, 2011

Everybody’s amazed about the incredible things done with Kinect and Processing + Arduino. Tutorial need!

This is a project in development for the module “Digital Ecologies”, at the Bartlett’s Adaptive Architecture and Computation MSc. – University College London

A Delta-Robot is controlled by a Kinect through Processing and Arduino. The movements of the performer control directly the position of the robot’s effector, and the rotation and opening of the gripper.
Once the plattform is properly calibrated (still a little rough round the edges!), several autonomous behaviours will be implemented.
