Sometimes when tuning various electronic hardware we need simple signal generator with various waveform and frequency. One of the options is to by a professional with variable gain professional coating and many additional functions. But if you are an amateur you might want to build one. This small project is dedicated for building one of …
Introduction Approach used for creating the pure sine wave described in this paper is done through manipulation of mathematical representation of the original sine wave. It is done by dividing half the sine wave into m (even number) segmentations, where area under a quarter of the sine wave from 0 to π/2 resembles series of …

And now for something completely different: A little robotics project for the weekend. The described robot can be build entirely from model making supplies and materials from the hardware store. Also only very few tools are needed. A metal saw, a drill press, a vice and optionally a tap will suffice. And here you can …
Update May 4 2012: I am still working very hard on version 3 of Picopter. The new version’s hardware is already done. There are new 3D printed motor holders. I’ve done some measurements with regards to mass and radio spectrum. I’ve posted stuff to http://www.frank-zhao.com/picopter_forum/index.php including the new design files, so take a look. Update Feb 24 2012: …
Since iRobot hasn’t provided linux users with a way to use the command module, I had to figure it out myself. Don’t be intimidated, its not hard at all, really. All you need to do is run a couple of scripts. Lets get started, shall we? Step 1 Get the goods For this tutorial, I’m assuming you have …
What this is: This instructable will show you how to make your Arduino into an R/C interface that you can use for just about anything requiring remote control. I will also show you how I built an R/C lawnmower using my Arduino, a cheap R/C transmitter and receiver pair, and a couple of electric-wheelchair motors from Ebay. I have used …

This Instructable will show you how to build your own Web Connected Robot (using an Arduino micro-controller and Asus eee pc). Why would you want a Web Connected Robot? To play with of course. Drive your robot from across the room or across the country, using nothing more than Skype and a web browser (nothing …

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 fair. …
