MAKE Asks: First Arduino Projects
Make: Asks is a weekly column where we ask you, our readers, for responses to maker-related questions. We hope the column sparks interesting conversation and is a way for us to get to know more about each other.

Levitating Light With Wireless Power Transfer
Chris Rieger, an EE student at the University of Queensland, built this light that both levitates and gets its power wirelessly. This is a project I’ve been working on for about 6 months now next to my regular studies. It is a levitating light bulb. This project came to life when i saw Jeff Lieberman’s […]
Mindstorms Holonomic Robot
Ray McNamara of Launceston, Tasmania, built this omnidirectional robot using a Lego Mindstorms parts, Technic motors, and is programmed in RobotC. I really love how Ray explains exactly how he designed and programmed his robot! A Holonomic platform is one of the many types of Holonomic drive trains — it can move forward and backward […]
Details of C64 Bass Guitar Hack
The always inspired Jeri Ellsworth outdid herself at this year’s Maker Faire Bay Area. Jeri is known for the phrase “Did you bring a hack?” and she lives by such sentiment — Jeri always brings a hack. This year, at Maker Faire, it was a Commodore 64 Bass “keytar” that makes use of the original […]
How-To: Read a ROM
NYC Resistor member Adam Mayer just posted this fantastic guide to reading the data off of old EPROM chips. To grab the data, you’ll need an Arduino Mega (or a microcontroller with 24 I/O pins), jumper cables, breadboard, and of course an EPROM to read.
Use ShapeLock for Semi-Permanent PVC Glue Joints and Fittings
One of the downfalls of using PVC pipe as a construction media is that your joints are either permanent, or they fall apart when pulled. If only there was a way to make a robust, temporary connection. Thanks to Bill Waters’ happy mistake, he discovered how to do just that by using ShapeLock (PCL.)
Engineer Guy vs. The Lead-Acid Battery
Here, friends and neighbors, is the eighth and final video of Engineer Guy series #4. The element of the week is called ‘plumbum’ in Latin, abbreviated to ‘Pb’ on the periodic table, and generally known as ‘lead.’ Formed into electrodes with its oxide and submerged in sulfuric acid, lead is an essential component in the ignition batteries that start cars and other gas-powered vehicles.
