A Nokia Shield For The Arduino

The Nokia 3100 is a classic in the circles we frequent. The LCD in this phone is a very cheap and very common display, and it was one of the most popular phones since the phone from Bell, making it a very popular source of cool components.

Now everything is an Internet of Thing, and cellular data for microcontroller projects is all the rage. [Charles] thought it would be interesting to use the famous Nokia 3100 to transmit and receive data. After battling with some weird connectors, he succeeded.

The Nokia 3100 doesn’t have a USB connector, as this phone was made before the EU saved us from a menagerie of cell phone chargers. Instead, this phone has a Nokia Pop-Port, a complex connector that still has TX and RX pins running at 115,200 bit/s 8N1. By fitting a USB socket onto a prototyping board, adding a few level shifters, and connecting the pins in the right order, [Charles] was able to get his Arduino talking to an old Nokia Brick.

[Charles] isn’t quite at the level of sending SMS from his confabulation, and even following a tutorial from [Ilias Giechaskiel] didn’t work. [Charles] is looking for help here, and if you have any suggestions, your input would be appreciated.

There is a problem with using a Nokia 3100 as a cheap Arduino cellular shield: it’s only 2G, and sometime soon those cell towers will be shut down. For now, though, it works, and once those 2G towers are shut down, there are plenty of options with cheap, early Android and iOS phones.

Steeping Tea Perfectly With An Arduino

While most of us here at Hack a Day can’t live without our daily java, we do understand and respect the tea drinking hackers out there, like [Brian McEvoy] the 24 Hour Engineer. Like any self-respecting hacker, [Brian] seeks to improve the efficiency of day-to-day tasks in order to spend his time on things that really matter — so he decided to automate his tea cup.

He’s 3D printed a small tea-bagging mechanism that a little RC servo motor can actuate, which allows him to control the amount of time a tea bag spends steeping in his mug. Another 3D printed enclosure includes the Arduino, a few buttons, and an LCD screen to allow you to select the steeping time for your favorite herb. In fact, the majority of this project is 3D printed which means the majority of the cost comes from the minimal electronics required — stuff you probably already have lying around. He’s also included all the design files you need in order to make your own.

The project has been in process for a while, but he’s finally finished it off, and it works great. If you’re hungry for some of the nitty-gritty build logs and troubleshooting a long the way, he’s got a whole bunch of blog posts from throughout the process.

Adafruit And The Arduinos At Maker Faire

The apparent lull on the Arduino front the last few weeks was just the calm before the storm that is the Bay Area Maker Faire (BAMF). Both companies claiming the Arduino name were there over the weekend, with news and new products in tow. Ironically, you could see from one booth straight over to the other. Small world.

Perhaps the biggest news from Arduino LLC is that hacker-friendly Adafruit is now going to be making officially-licensed boards in the US. Competing with this news, Arduino SRL brought its new boards, including the Yun Mini and ARM-powered Arduino M0. And [Massimo Banzi] and Arduino LLC seem to be taking an end-run around the Arduino SRL trademark by announcing the “Genuino” brand for European production. For all the details, read on!

Vacuum Gauge Display; Arduino Replaces Industrial

Arduinos! They’re a great tool that make the world of microcontrollers pretty easy, and in [cptlolalot]’s case, they also give us an alternative to buying expensive, proprietary parts. [cptlolalot] needed a gauge for an expensive vacuum pump, and rather than buying an expensive part, built a circuit around an Arduino to monitor the vacuum.

pressure-gauge-thumbThis project goes a little beyond simple Arduino programming though. A 12V to 5V power supply drives the device, which is laid out on a blank PCB. The display fits snugly over the circuit which reduces the footprint of the project, and the entire thing is housed in a custom-printed case with a custom-printed pushbutton. The device gets power and data over the RJ45 connection so no external power is needed. If you want to take a look at the code, it’s linked on [cptlolalot]’s reddit thread.

This project shows how much easier it can be to grab an Arduino off the shelf to solve a problem that would otherwise be very expensive. We’ve been seeing Arduinos in industrial applications at an increasing rate as well, which is promising not just because it’s cheap but because it’s a familiar platform that will make repairs and hacks in the future much easier for everyone.

Arduino IDE Becomes More Open, Less Snarky

Version 1.6.4 of the Arduino IDE has been out for a little while now, and it has a couple of notable changes. To our eyes, the most interesting change makes adding support for non-standard boards and their configurations within the Arduino IDE a lot simpler. We’ll get into details below.

unnamedBut before that, it’s time to bid farewell to the cheeky little popup window that would deliver a warning message when using a board bearing the USB IDs of their former-partner-turned-competitor. We absolutely agree with [Massimo] that the issues between Arduino SRL / Smart Projects and Arduino LLC are well-enough known in the community, and that it’s time for the popup to fade away.

Now on to the meat of this post. The new “Board Manager” functionality makes it significantly easier for other non-Arduino products to be programmed within the Arduino IDE. Adafruit has a tutorial on using the Board Manager functionality with their products, and it basically boils down to “enter the right URL, click on the boards you want, download, restart Arduino, bam!”

The list of unofficially supported third-party boards is still a bit short, but it includes some stellar entries. For instance, Adafruit has provided the files needed for the ESP8266, which recently received the Arduino treatment. This means that you can simply point your IDE at Adafruit’s URL, and it’ll set you up with everything needed to develop for the ESP8266 from within the comfy Arduino IDE.

Arduino-Based Dispenser Delivers Liquids, Powders

If you like to cook or bake, you probably don’t measure everything out in little bowls and ramekins before you start. Well,unless you also happen to like doing dishes. Even so, there are a lot of measuring spoons and -cups that end up getting dirty in the process. But what if you had a measuring machine to dole out spices and low-viscosity liquids in specific quantities for you?

[enddev]’s creation is based around an Arduino Mega, and the interface is three buttons and an LCD. The user selects between liquid and powder, followed by the desired measurement. If liquid is chosen, the peristaltic pump is engaged to deliver the specified amount through silicone tubing. The current powder setup uses a kitchen scale, which the designers found to be inaccurate for small amounts. They believe that a volume auger and stepper motor would be ideal.

The team mentions that the powder delivery system is better suited for flakier substances since it’s basically agitated out of the container. This makes us think this would be great for feeding fish. If you take this admirably-written Instructable and use it to feed your fish or something, let us know. Their code is on the gits.

Linear Book Scanner Does it with Arduino

About two and half years ago, the Google Books team open-sourced the plans for their book scanning rig, and there was much rejoicing. As [Dany Qumsiyeh] explained in the Google Tech talk we linked to at the time, the scanner uses a vacuum to lift the next page from the stack and turn it, saving hours of human labor and, admittedly, putting books in a little bit of danger.

[Chris] tipped us off about a different take on the linear book scanner created by [Forssa1] that uses server fan to turn the pages. [Forssa1]’s rig is built from laser-cut acrylic and employs two handheld scanners driven by an Arduino Mega. We don’t have a great deal of information about this build, but you can check it out after the break.

UPDATE: [Forssa1] checked in with us and sent a link to more build photos of his book scanner.
