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
This project by newtonn2 is a nice DIY Small Bench Power Supply. I like the case design which is lettered with the toner transfer method. Great looking results. “The heart of the unit is basically the same as on the other power supply. It is based on the LM2596S. This IC can handle up to 3A with a good heat sink. I would use it only for 2A to
Mike Harrison from Mike’s Electric Stuff shows off how he used a small thermal imaging sensor and incorporated it into a custom little project with a iPod Nano screen. With a tiny bit of polish this thing would be a great product on any hardware store shelf!
If you need some computing power on the go you might want to look into adding a car computer. Sentdex shows us how he does it on the cheap, the top of the great find is the $17 monitor. It has a Raspberry Pi as the heart, an ODB interface and a camera to loop record. An interesting power management system allows the system to detect when car power
