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. […]
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 […]
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 […]
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 […]
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 […]
This example shows you how to read different analog sensors to change the brightness of the three colors in the RGB LED. In this example you will read the amplitude from the microphone, the amount of light on the light sensor, and the position of the linear potentiometer. These three sensors will control the intensity […]
No longer will you have to pay hundreds of dollars for a heart rate monitor! The Smart Heart Monitor will be able to do all of your cardiac measuring needs for you! The Smart Heart Monitor measures the user’s heartbeat using an LED and a very sensitive photo-resistor attached to the user’s ear. A light […]
I have wanted to build my own robot for awhile now. But after many tried and failed attempts, I was losing hope that may ever happen. I discovered that there wasn’t a small, robust, super easy to add-on to, robot that was within my budget to get. After hours of research and many robot kits later, i […]
Tested ExtraCore boards and kits are now available for sale from Rugged Circuits. What is it? This Instructable will give you all the files and information you need to make your own Arduino Compatible in small surface mount package. It requires a board manufactured to about 9mil precision. I recommend having the board manufactured at […]
Setting up an Arduino on a breadboard has become a process I have grown to love. Within a few minutes you can have a fully working Arduino platform to work with as you will see in this tutorial. There have been several occasions when I was at school and quickly put together one of these […]
