Arduino user Geotechbd wrote us from Bangladesh to share his experience:
Our company here in Bangladesh owns a quite old concrete batch plant, which had full manual control requiring an operator to control 14+ switched and observe 3 mechanical scales (dial gauges). I was successful to upgrade this plant to an automated unit requiring minimal operator input using custom made Arduino Uno compatible board and LIFA. Wiring is still messy which I shall take care in the near future. (more…)
How to enhance performance in gaming from an engineering point of view? dekuNukem created a hands-free finder built using Arduino Micro to accomplish the task of chaining fishes at full speed and without fail at a touch of a button:
The fishing keeps going without human input until a shiny shows up, at which point it stops and sound a buzzer to notify the user.
It took 81 chains to catch a shiny in this case, but during my other tests it’s usually around 50, and sometimes even less than 20 chains get you one.
What happens to electronic components at cryogenic temperatures? That’s the main question Mikail tried to answer with his experiment using liquid nitrogen and Arduino: 65.3Mhz@-196°C. Check the video below to see the magic:
An overview of the inside of the dock (very messy, I know )
I am using a dual potentiometer (2 pots in one). Here you can see one pot connected to the amplifier on the left to control the volume, and the other connected to the Arduino on the right to read the position of the pot.
Here you can see the 4 wires used to control the volume display connected to digital input 2, 3, 4 and 5 on the left side of the board. And you can see the potentiometer connected to 3.3V, analog input 0 and ground on the right side of the board.
Steve Spence, an amateur organic farmer in Andrew, South Carolina, has a smart way of irrigating his vegetables. He uses water from his pond and the fish waste to fertilize his plants, a technique known as aquaponics. But the critical balance between the makeup of the water and soil means Spence has to know exactly what’s going on in both. Real-time information about the pond’s make up is imperative to know he’s giving his veggies the best drink of water.
This is the beginning of a post published on ModernFarmer a couple of days ago. Click here to keep reading about nice stories and real examples (+ 5 farm hacks!) on how to use Arduino for farming and what happens when farmers start embracing the modern trends of DIY tech.
Are you a student living in a closed dorm? Ever wished for a window on a blank wall but maybe the house owners would not allow you to build? All of you would have seen tutorial about moodlamp with RGB LED strips and Arduino. This seems to be the perfect application for it.
For this tutorial the maker used Superlight LEDs and an Arduino which provides an effect directly corresponding to the preset daytime light outside.
The main reason of our visit was getting in touch with the Bio-Hackers and Maker Community meeting there, get them involved in the Call of Makers for the upcoming European Maker Faire in Rome. We had a good time in talking with them about the strange situation we are witnessing here in Europe: many languages, many nations, one big movement of people tinkering around stuff. Get everybody to know about this event and the chance to meet and talk to each other is a massive task. But we are going to overcome it!
The place is just super. I’ve been involved in the making of a makespaces in the last three years of my life, but I have no words in describing the feelings I had in witnessing the massive amount of contents that basement kept. No joke.
I tried my best in recovering those objects, those feelings and this odd XXIst century knowledge in a pool set of Flickr, where I tried to describe and follow the different projects I’ve seen.
Why visiting makerspaces is to me just like standing on giants shoulders? Basically because I know the problems and I see better, streamlined solutions answering (better than ours in Fablab Torino. You guys feel free to comment and make me feel naiv about the Fridge, Bio Hacks, the communication billboards, and the AtMEGA 16u2 hack from Dennis.
This project by Greg is about building a smart litter box for his cats:
We have three cats and the litter is difficult to control. So I had been thinking through a project to build an enclosure. Once I stumbled on Arduino the doors of opportunity were opened. I ordered the electronics and got started on my project right away. So far the Arduino is activating exhaust fans, lightng, and a Lysol spray dispenser. It tracks the number of times the fans are activated and uses a piezo buzzer to alert a filter cleaning. I plan to use it to trigger cleaning based on usage and track each cats potties so we can control their stink before its too late.
A nice video about this project can be found on YouTube.
It’s always nice to see how creative makers approach communication issues in DIY projects, and today we would like to highlight the approach followed by Alex, from InsideGadgets.
On his website, he provides a detailed tutorial on how to use an old Nokia 6110 (or any derivatives) to send SMS messages by exploiting the Nokia’s F-bus, a simple bi-directional and full-duplex serial protocol.
After considerable reverse engineering work, made possible by useful online documentation, Alex finally managed to send a SMS from his Arduino board, connected to the phone, thanks to AVR libraries made available by AVRFreaks.
Have you ever wondered to use your old-fashioned NeXT keyboard with your current, non-ADB computer? The main issue that needs to be solved regards how to interface this ADB keyboard (standing for Apple Desktop Bus, an old protocol used in former NeXT and Apple computers) with a standard USB interface.
In this nice tutorial, Ladyada and Pt describe the approach they have used, based on an Arduino Micro board and… some luck in searching for the right information about the scancode table of the keyboard ^^.
