Open source pocket USB oscilloscope; 30 MHz, multi-platform


by Graham Prophet @ edn-europe.com:

Running on Apple iPad, Android, Microsoft Windows and Linux, LabNation’s (Antwerp, Belgium) open source USB oscilloscope, SmartScope, is the result of a Kickstarter campaign commenced in 2014 – the project raised 645% of the funding goal within 30 days.

Believed to be the first test equipment designed to run on multiple operating systems and platforms such as smartphones, tablets and PCs, the lightweight SmartScope is powered directly from the host’s USB interface suiting it for many test and measurement applications far from the workbench.

An Android Reflow controller that anyone can build


Andy build an android reflow controller based on ATMega8L . He writes:

Welcome to the never ending saga of Andy and his reflow controllers. About a year ago I published a project writeup showing how I built a PID-based reflow controller. It featured a 640×360 graphical LCD from the Sony U5 Vivaz mobile phone and was all-surface mount. It worked well and continues to serve me well to this day but I always thought that there were improvements that I could make in several areas.

Firstly, there’s no reason why it should have been all surface-mount. The LCD in particular has a 0.4mm connector that many people will find very hard to solder by hand. After all, presumably you’re building a reflow controller to help solve that very problem. Chicken and egg.

The Creator C120 dev Board


by elektor.com:

Although originally announced back in August, the Creator C120 development board from Imagination Technologies can now be pre-ordered for delivery in January 2015. This capable little board can run Linux and Android. The board’s hardware includes a dual core, 1.2GHz MIPS32 based processor, PowerVR SGX540 graphics, 1GB DDR3 memory and a 4GB flash memory. It comes pre-installed with Debian 7 and other Linux distributions will be available in the future, including Gentoo and Yocto, as well as a version of Debian 7 that complies with the principles of the Free Software Foundation. Users can also install the latest version of Android v4.4.

Code generator for custom Android/Arduino menus


by drmpf @ instructables.com:

The first instructable shows you how to use the free pfodDesigner available on GooglePlay to design Android menus to switch Ardunio outputs on and off from your Android mobile, without you having to write any program code at all. The Fish Tank picture above shows the example designed in this instructable.

The example project shown here is suitable for complete beginners. This instructable does not require any soldering and No coding experience is required.

Once you have finished this instructable you will be able to design whatever menus you need to switch Arduino outputs on and off. When you have completed the second instructable (to be posted later) you will be able to switch real things on and off from your Android mobile, via relays connected to Arduino’s digital outputs.

IOS-Controlled Arduino waveform generator


by Annikken @ instructables.com:

This waveform generator is based on the work by Amanda Ghassaei. Waveform generators (or function generators) are used for testing and debugging circuits. e.g. frequency response of op amp or sensors. This waveform generator is powered by Arduino with Annikken Andee shield – a device that lets users create iOS/Android interfaces without iOS or Android programming at all. It outputs sine, triangle, saw and square waves. Frequency is controlled by means of a slider (on iOS/Android device) and wave type is selected using on screen iOS/Android button. With a iOS/Android interface, you can add certain features not possible with hardware buttons. E.g. displaying different ranges of frequencies for each wave type, displaying meaningful controls for certain wave types. For example, the pulse width modulation slider is only visible for square wave types, its not visible for sine, triangle or saw wave forms.

Program your Arduino with an Android device


Jan_Henrik @ instructables.com writes:

in this Instructable I want to show you, how you can program your Arduino with your Android device. It is very simple and cheap. Also it allows us to program our Arduino where ever we want, this is usefull for permanently installed Arduino boards, like in light controllers…

Smartphone port? Try the Ear Hole


by elektor.com

Smartphone peripheral developers are limited to RF links via Bluetooth, NFC or WiFi when they need to pass data back and forth to the device. This can add significantly to costs and stand-alone peripherals also need batteries or an adapter for power. The Quick-Jack from NXP solves both problems; it turns the standard 3.5 mm stereo audio headphone socket found on most iOS or Android smart devices into a self powered data port and provides an interface for external switches, sensors or any other external equipment.

The Smartphone Quick-Jack Solution comprises a small board, a free example app for popular smartphone OSs, and design documentation.

BlueMatrix – Bluetooth controlled LED matrix

Luca Dentella has published his latest project: BlueMatrix. [via]

It’s a portable LED matrix display based on Arduino Uno, powered by a Lipo battery and connected via Bluetooth to a personal computer or an Android smartphone. I’ve also developed the controlling app for Android, available on Google’s PlayStore.

All the schematics, source files, inkscape files for the enclosure etc., are available on my blog and in my GitHub repository.
