Electro Labs has a new project posted, this time it’s an Arduino Lithium Battery Charger. With Lithium batteries you can’t just stick a trickle charge on the battery and call it done with a lot of older battery chemistries. There is quite a lot of technology packed into the design to get the job done and lots of room for user customization. “The lithium battery charger circuit is designed
Printing this car took just 44 hours our out of 44 parts. Just bolt on some electronics and wheels are you are ready to drive! Love the design but up close it doesn’t look polished like a metal vehicle but you can see that it goes together in thick levels. What will we see in the future? Instead of customizing your new car by picking a color, interior trim
 This DIY Clothespin Piano is a fun project by adamkumpf from fiddlewax that will give you small physical piano keys to let you play songs on your iPad without tapping the screen with your fingers. “Touchscreens are great, but when it comes to playing music on them, the lack of physical keys can be a drag. So I decided to round up some household stuff and make a piano
If you have a mailbox outside your house you might have to look at it many times to check to see if your mail flag is up. Of course this isn’t a very efficient use of your time. Wouldn’t it be great if there was some type of visual indicator in your house that would alert you when the mail has arrived? Wait no longer, Bob from Galactic Studios
If you think the price of 3D printers is hitting the floor check out what Mikelllc built for $60. About 80% of this EWaste 3DPrinter is recycled computer parts which is abundant and readily available. “First of all, we learn how a generic CNC system works (by assembling and calibrating bearings, guides and threads) and then teach the machine to respond to g-code instructions. After that, we add a
With the reliability of modern electronics vacuum tube making is a dying art. Here are some great videos demonstrating the laborious steps that go into creating them. “Vacuum tubes mostly rely on thermionic emission of electrons from a hot filament or a cathode heated by the filament. This type is called a thermionic tube or thermionic valve. A phototube, however, achieves electron emission through the photoelectric effect. Not all
If you are new into the world of BeagleBone Black this book will walk you through getting you started and building some interesting projects that you can easily build upon. The book is well documented and explains what the code is doing step by step. It is available at most book stores and many places online such as Amaon and Indego. “This wickedly inventive guide shows you how to
