It has been quite some time since my last post – as often happens, life intervenes and this time just a bit too much hospital time both for myself and one of my kids. Things are good now and normal can resume…  LED Driver For years I have had this Black&Decker Firestorm FSL18 flashlight, but […]

Bleuette project is hexapod robot equipped with 6 legs that can be operated without any external guidance. The French project is fully open hardware (made entirely with  an Ultimaker 3D printer) / opensource and operates on a Arduino Leonardo board with a custom shield developed for it and available on Hugo’s website, the author of the […]

If you want to RESET Arduino from the beginning without manually pressing the RESET button, there are a few ways. Here are two ways, using minimal wiring / circuitry. Step 1: Using 1 wire connected to the RESET pin 1. electronically, using only 1 wire connecting an OUTPUT pin (12 in this example) to the […]

Siduri named after the Sumerian god of happiness and merriment, is a smart coaster for your drinks. It recognizes when a glass is near empty and then glows yellow to alert waiters that you will be in need of a refill soon. Designed specifically for lounge and club settings, Siduri helps nightlife revelers politely draw […]

Last year I was fascinated by the “How to build your own Quadrocopter” by Lenz Grimmer and decided that somehow I should try to do a similar thing. This talk is about the way I’m building a bi-copter using lessons learned for last year’s talk and also with the errors I’ve made so far. My […]

There is no better way to hide a covert device than to stick it inside a larger conspicuous device. That said… Essentially, this is a guide for making a data logging system for use with the breathalyzer microphone. To accomplish this, an Arduino and a Logomatic SD data logger are embedded into an old and […]

This is a description of an open source/open hardware project of a remotely controlled Arduino (Freeduino) based clock/thermometer utilising power supply and VFD panel from a broken DVD player in a custom made acrylic enclosure. The aim of the project was to demonstrate what could be done from electronics that has been literally thrown away […]

Lusha and May created a “Text-Mat”. This surface can allow the user to write and send messages using one’s feet. This text-mat is designed to send secret messages during meetings or classes. The design utilizes conductive fabric and thread, as well as a flora-board. The program contains 7 preset sentences. The user can press a […]

In a wireless design, two components are the critical interfaces between the antenna and the electronic circuits, the low-noise amplifier (LNA) and the power amplifier (PA). However, that is where their commonality ends. Although both have very simple functional block diagrams and roles in principle, they have very different challenges, priorities, and performance parameters. How […]

I have recently acquired an Intel IoT Developer Kit as part of an Instructable Campaign. I am familiar with some embedded processing models and microcontroller environments such as the Arduino, but I found getting up and running with the Intel Edison to be a bit chaotic. I wanted to consolidate the information that I found […]
