Wood Lizzie is a DIY Soap Box Cart controlled via Wi-Fi

In the following 10-minute video, the Currah team is showing us all the details of Wood Lizzie, a project experimenting with Arduino Mega and Wi-Fi Shield, a very flexible steering system and the virtually unlimited control range afforded by WiFi and Internet Protocol:

The original plan was to construct one of the two-wheeled robots very popular with hobbyists but it was eventually decided that the resulting vehicle would be of very limited application and capable only of traversing smooth surfaces. However, note that the current design can be viewed as the drive of a two-wheeled robot coupled with a trailer by means of a 360 degree pivot. A slip ring capsule within the pivot enables the heavy battery and bulky control system to be separated from the drive and located on the trailer thereby distributing weight evenly between the four wheels.

DIY soap-carts were pretty common among kids in the first part of the 20th century and built from old pram wheels, scrap wood and, typically, soap boxes. They could provide a lot of fun for the family at very low cost and in recent years there’s a new interest in them especially to those appreciating their vintage look!

Batman Inspired Indoor Localization

Last August Arduino Tour landed in Singapore, hosted by The Hub Singapore. Davide Gomba held a workshop there and met a lot of cool people during the hackathon happening in the same days. Ted, one of the participants, submitted to our blog the Indoor Localization (see video below) project  he prototyped with his team during the 24 hours CodeXtreme hours:

Our idea is to convert existing speakers inside shopping malls into an indoor localization beacon. This allows malls to track the location density without adding extensive infrastructure since it uses embedded inaudible sound signatures in music that shops play in the malls. In short, instead of tracking Joker, we use Arduino (with WiFI Shield & MP3 Shield) and Android to track people (customer) inside a mall.

A cheap WiFi interface for Arduino

Thursday, December 27th, 2012

In this tutorial, Luca shows how to add WiFi connectivity to your Arduino boards without using a WiFi shield. Instead, he has combined a standard Ethernet shield with a commercial (and quite cheap) WiFi router:

I found the TL-WR702N nano router by TP-LINK that, with a cost of about 20€ on eBay, can work also as a wireless client: in this mode the router acts like a “bridge” between the device connected to its ethernet port and a Wi-fi network.

After a simple setup, where Luca configured the router as a WiFi client, the Arduino board has become accessible from the wireless network. Enjoy! :)

Arduino Wifi Shield is back on the store!

Tuesday, October 2nd, 2012

We’re happy to announce the Arduino Wifi Shield being back on the Arduino Store. Since we launched it back in August we had an overwhelming request for the product that ended up in solding it out.

Welcome back, bro.
