The first approximation is based on a modification of an expression developed by Wheeler; the second is derived from electromagnetic principles by approximating the sides of the spirals as current-sheets; and the third is a monomial expression derived from fitting to a large database of inductors (and the exact inductance values). All three expressions are […]

The Solar Powered-Bird Proof Squirrel Feeder w\ Camera will allow squirrels to retrieve seeds, nuts, and corn kernels without worrying about those pesky birds stealing all their food. While your squirrel enjoys the spoils of your feeder, you’ll enjoy lovely digital photos to entertain and impress your friends, family, and fellow squirrel lovers. This environment […]

If you´re deciding whether it´s worth to use a backup battery, we bring you a few remarks why to go for it or not. Lithium battery Xeno Energy with a lifetime of over 10 years and rules for their usage were brought to you in our article „10 years of operation for 1 battery?”. They´re […]

This project describes the design of a very low budget 3D Printer that is mainly built out of recycled electronic components. The result is a small format printer for less than 100$. First of all, we learn how a generic CNC system works (by assembling and calibrating bearings, guides and threads) and then teach the […]

This instructable will show you who to build a rgb lighting system with an Arduino. You can also control it with an iPod/iPhone/iPad using touchOSC. In my previous instructable I showed how to control one rgb led in this you can control heaps with a single chip the ULN2003A. Step 1: Parts You will need […]

Goals Understand the Analog Signals and use your knowledge to program your Arduino and let it play music Get known of the Seven-segment display and use your Arduino Board together with the Shift Register to control the number. In the Second Week you will be asked to implement a circuit to combine these first two […]

***Disclaimer***This instructable is documentation for a work in progress. Although the project is not yet complete, it has reached a place where I believe it can begin to be beneficial to other makers. The concept for this project was spawned when a friend suggested I be Slenderman for Halloween. When I first looked at pictures, […]

Well, the “Test PCB” project is finally underway. In case you don’t remember my original blog, the idea is to send a PCB design out to a half-dozen or so low-cost PCB prototype shops, then review their service and quality. I’ve created a 6 × 6cm double-sided design for this project. I would have made […]

Ever wanted a robotic liquor server? I purchased a Lynxmotion robotic arm last year and an Arduino (deci) to play around with. I had it serial controlled with a joystick and it was a great way to start in robotics. More recently I wanted to take on another micro-controller related project for a university science […]

Finalized Prototype Shown below is the finalized prototype. The purpose of the prototype was to demonstrate the feasibility of a small, highly maneuverable search and rescue robot. As such, the completed prototype was successful. Capabilities include a ground speed of 10 inches per second, battery life of 50 minutes, wireless range of between 50 and […]
