Build a bare bones Arduino clone which maximizes its use of real estate. Check out all the stuff crammed into a small swath of strip board.

Build a bare bones Arduino clone which maximizes its use of real estate

It’s got that characteristic look of a roll-your-own Arduino board, which is exactly what it is. [S. Erisman] shows you how to build your own copy of his YABBS; Yet Another Bare Bones Arduino (on Stripboard). The strips of copper on the bottom of the substrate run perpendicular to the DIP chip and have been sliced in the middle. This greatly reduces the amount of jumpering that would have been necessary if using protoboard. Pin headers along either side of the board have been altered to allow for soldering from the wrong side of the plastic frames.

Ringing in at as little as $2-$4.75 a piece you’ll have no problem leaving this in a project for the long hall. 11 Arduino projects that require major hacking skills—or a bit of insanity. Raspberry Pi has received the lion's share of attention devoted to cheap, single-board computers in the past year.

11 Arduino projects that require major hacking skills—or a bit of insanity

But long before the Pi was a gleam in its creators' eyes, there was the Arduino. Unveiled in 2005, Arduino boards don't have the CPU horsepower of a Raspberry Pi. They don't run a full PC operating system either. Arduino isn't obsolete, though—in fact, its plethora of connectivity options makes it the better choice for many electronics projects. While the Pi has 26 GPIO (general purpose input/output) pins that can be programmed to do various tasks, the Arduino DUE (the latest Arduino released in October 2012) has 54 digital I/O pins, 12 analog input pins, and two analog output pins. Arduino's array of inputs and outputs proves crucial in projects from building robots to 3D printers, said Jason Kridner, co-creator of the BeagleBone line of products that combine Raspberry Pi-like horsepower with Arduino-like capabilities.

Dublon spent a year testing Tongueduino on himself. Interfacing a sensor with an Arduino. The world of hobby electronics is one that has seen explosive growth and massive changes over the past few years. The biggest changes have come from the level of computing hardware that is available to the hobbyist. From very simple microcontrollers to full PCs on a USB stick, all sorts of options are available. One of the more popular options is the Arduino, which falls between these two extremes.

Use Android’s chronometer timer widget for your apps. Look at this demonstration of Android's chronometer widget, and see if it's the right tool for the job.

Use Android’s chronometer timer widget for your apps

One thing all computing platforms have in common are timers. In fact, every compute platform I've worked on has at least half a dozen kinds of timers. Android is no exception. Android supports Java and system timing mechanisms; additionally, it even has a UI widget called chronometer that can act as a timer for your applications. This tutorial demonstrates Android's chronometer widget. 1. 2. Don't Spend Money On An Arduino - Build Your Own For Much Less. I love my Arduinos.

Don't Spend Money On An Arduino - Build Your Own For Much Less

At any point, I have quite a few projects on the go – prototyping is just so easy with them. But sometimes, I want to keep the project functional without buying another Arduino. How to build a 5$ Arduino (clone) If you are like me and build projects with Arduino, you must have felt the frustration with ripping your project apart, because you wanted to build something else with that Arduino.

How to build a 5$ Arduino (clone)

I have had the same issue many times, so I decided to find a way to solve this once and for all. Hence, how to build an Arduino clone for less than 5$. Warning: Now before we continue a warning. This post explains how to build Arduino cones for less than 5$, but it will mean that you either get creative with you current Arduino to program the Arduino bootloader, or you invest a bit in a standalone ISP programmer and a FTDI interface board (total about 20$ one time investment). The reason we can build a relative cheap Arduino clone is that Arduino consists of the following parts: - USB to serial converter (also known as FTDI) - ATMEGA328p with oscillator and bootloader - 5V power circuit.

Basic Arduino Connections Quick Reference Guide. Open Source Hardware Files. Freeduino is a collaborative open-source project to replicate and publish Arduino-compatible hardware files.

Open Source Hardware Files

The Freeduino Eagle SCH, BRD and Gerber production files allow users to create boards that are 100% functionally, electrically and physically compatible with Arduino hardware. While Arduino is a protected trademark, Freeduino comes with a free and unrestricted license to use the Freeduino name, available for any use. This means you can do whatever you want with these files. The idea here is to make available the Eagle files you would need to make your own Freeduino variant board. Freeduino currently consists of a Diecimilia-equivalent schematic and 0603, 0805, 1206 and through-hole routed board files.
