In early April 2016, the Arduino organization announced a complete change in strategy for how Arduino users will code and compile projects. Arduino Create is a brand new platform that allows you to code and compile online, share projects, and tap into existing community resources with much less effort than has ever been possible before.
GPS trackers are always interesting because they’re so versatile. Location-based services have exploded in the last couple of years, and are poised for more growth as we get further into the 2010’s. At the heart of all of these services is a GPS tracker, and a method of transmitting position data to a server, where a provider (or hacker) can do something useful with it.
The Raspberry-Pi has been a media darling as of late, and deservedly so. It’s a full computing platform that can do many wonderful things, all for less than a few day’s worth of Starbucks lattes. But what if you simply need moah powah?
As the Arduino surges in popularity, people keep dreaming up crazier and more complex ways to use it. We’ve rounded up five of the most impressive Arduino projects on the web to show what’s possible with such a versatile and inexpensive platform. Be warned – these projects aren’t for beginners, but if you’re looking for a challenge and something to brag about, they could be just the ticket.
A new Kickstarter project aims to provide a low-cost, open source platform for building a GPS tracking device. The author, Wayne Truchsess of DSS Circuits, explains that a few years back, his brother in law had a PS3 stolen during a long power outage in the depths of winter. Not wanting to repeat history, Wayne bought a fake PS3 case on eBay and developed his own prototype position tracker to put inside it.
The tracker consists of a GSM cellular modem, a GPS unit, and an accelerometer, all tied to an Arduino and a LiPo battery to provide brains and power, respectively. Normally, the device lies in wait, asleep to save power. If it detects motion, it turns on the modem and alerts a preconfigured phone number via SMS. The owner can then respond with various commands to turn position tracking on or put the device back to sleep.
In a previous post, we covered online IDEs for embedded software development. In order to run embedded programs you need to, well, embed them in something, so we also included a paragraph on Upverter, a tool for collaboratively editing and sharing circuit schematics. Hardware design is an area that’s still relatively untouched by the web application revolution, and we always love to see new innovation.
More recently, we ran across CircuitLab, an alternative schematic tool with some unique features. On the surface, the site seems extremely similar to Upverter: fire up an online editor, create your circuit in the browser, then save it to your account. At any point in this process, you can share a link to your circuit to let others view it and collaborate.
HC Gilje has posted an excellent guide to serial communications with external devices using the iPhone. There are lots of resources out there for setting up serial devices, but the landscape is fragmented. And as always, Apple is not exactly falling all over themselves to let you hook up peripherals. As Gilje succinctly puts it:
Apple has not made it easy to let the iphone communicate with external devices. Basically, you need a jailbroken phone to do anything.
In a previous post, we highlighted a DIY oscilloscope project that used an Arduino Pro Mini and an old Nokia cell phone LCD to create a quick and dirty oscilloscope. That build is great for a portable solution. However, what if you want a bit more power and polish?
GreenTerraFirma has some very cool links regarding DIY power generation and sustainability projects. This page deals exclusively with wind turbines, and posts several videos on how to make your own out of two 55 gallon drums. The project is dirt cheap if you can source parts well, and doesn’t take a lot of specialized tools either. The author machines gears out of some cheap cutting boards, but mentions that you can make an equivalent drive system out of belts and pulleys, which can be store-bought.
