In this tutorial we make an Arduino-compatible board that holds the microcontroller in a ZIF socket. Updated 18/03/2013 Today we are going to make a different type of Arduino-compatible board, one that has a ZIF (“zero insertion force”) socket. Our reason for making this is simple – now and again you may need to program

During the past spring a good friend of mine bought me my first house plant, a Lady Palm, and I’ve found myself rather invested in keeping it alive. To that end I wanted to monitor the plant’s environment so I could ensure that its needs were being met. My first thought was another ITP project,

This how-to takes you through all the steps of making your own arduino on a perfboard or perfduino! Arduino microcontrollers are great for learning about physical computing and are very useful for rapid prototyping. Arduino’s simple programming language makes it a favorite of hobbyists and diy-ers around the world. Because arduino boards range in price

Disclosure: This project operates the ATmega328-P-PU outside the published ATmel specifications: According to ATmel, the 328P requires slightly over 3.3V to reliably start the oscillator at 16MHz and to otherwise perform acceptably. Lab testing here at SofKinetics has shown that the ‘board-duino’ 328P-PU can withstand below freezing and above 130F temperatures and that the 16MHz

After I finished my last project, I couldn’t stop thinking how to build an AM receiver, that would also operate in conjunction with my little friend Arduino. To minimize a workload and complexity, especially with RF part of the circuitry, I come up to conclusion, that SDR (Software Defined Radio) is the best choice for

When I’m building Solar Shrubs and other solar-powered creations, I often scavenge cells from various off-the-shelf devices such as solar garden or security lights. But these cells are rarely labeled as to their voltage, current, and power output. So it’s off to my bread-boarding station. First, I put each cell under a lamp and connect it to my multimeter to get

Build an Arduino-powered version of the “Four Letter Word Generator” (FLW). This version generates “words” on the fly – it does not use a list. The “original” version from the 1970’s used B7971 nixie alphanumeric tubes. These tubes are getting hard to find and they’re certainly expensive. They also require interfacing with high voltage and

Greetings, One late night of web surfing I came across some 45 Degree Extension boards. Thinking to myself “Wow!” that’s cool and then I looked at the price…$27.00 before S&H. “Yikes!” I’ve been looking for an excuse to learn Eagle PCB layout software and this was the project I decided to cut my teeth on…”Wing

Reginald started from the simple, yet bold idea to control a bot from anywhere in the world with a live video feed. What I wasn’t expecting was for Reginald to develop into an involved, feature rich project. With my work and money, I was able to complete a project exactly to my satisfaction and more.

This page explains how to build an RFID reader with just an Arduino (Nano 3.0 was used in testing, but other models may be compatible), a wire coil made by hand, and various affordable common components. Credits The hardware and software designs for this project are based in part on the ideas, code and schematics
