Cordless Candlestick

Cordless Candlestick

Long-time MAKE reader Adam Ben-Dror carefully reskinned a 2.4 Ghz cordless phone handset with a 90-year-old candlestick telephone. A DTMF converter in the base preserves the function of the original rotary dial. Calls are begun by lifting the earpiece and ended by hanging it up. As Adam writes, “the only sign that anything has been altered is the missing cord.”

How-To: RF Shielded Wallet

How-To: RF Shielded Wallet

With short range wireless technology becoming increasing prevalent in the various cards we hold in our wallets, Serge Negrashov decided to make his own radio frequency shielded wallet to block any potential wireless data snoops. He used extremely strong Kevlar-Nomex as the fabric and painted the inside with silver epoxy to give the wallet its shielding quality. If you’re looking for a budget version, he says that regular epoxy with a layer of tin foil might work as well. What do you think of RF shielded wallets? Better safe than sorry or overboard paranoia?

Getting Started with XBee Internet Gateway (XIG)

The XBee Internet Gateway (XIG) is a Python script for Digi’s ConnectPort wireless to ethernet gateway which lets you connect your XBee wireless modules to the internet fairly easily. Jordan Husney, lead programmer of the XIG project, has started releasing a series videos all about XIG and what you can do with it. In the first video, Jordan introduces XIG and walks through the process of setting up the gateway. The XIG is also discussed in Rob Faludi’s Building Wireless Sensor Networks and is a core component of my own Networked On Air Light project. If you’re looking for a way to put your project online using wireless mesh networking, be sure to check out XIG.
