FlatFab. High-Power Control: Arduino + TIP120 Transistor. Up until now, we have talked about working with a lot of low-power devices.

High-Power Control: Arduino + TIP120 Transistor

Sensors, LEDs, ICs, and the like are all capable of being powered directly from your Arduino, but as many awesome 5 and 3.3v components as there are, eventually you will find yourself holding a 12v solenoid, motor, or light and wondering “How the heck am I supposed to control this from my Arduino?” Well today we are going to talk about doing just that from a magical device know as a transistor, specifically the TIP120 Darlington Transistor. The reason I’m covering this particular transistor is because it is readily available, and you can usually pick one up from Radio Shack, Adafruit or other local parts store in a jam, but you can use any NPN darlington transistor like the BD651 exactly the same way.

How this works WARNING: I am about to simplify the crud out of this, so beware… it is here in an attempt to explain, in simple terms, what is going on. Hooking it up / What’s the diode used for?

DIY Bicycle Dynamo USB Charger for Smartphones and Battery Packs – Rob Thomson's Adventures. In this post I describe how I made a USB smartphone charger for a hub-dynamo-equipped bicycle.

The idea came from multiple sources, including Mr. Howdy, Arenddeboer.com, and Peter. But they assume the person making the charger knows how to read a circuit diagram. I cannot understand a circuit diagram. EURECART - Electronique. PHOTOS. J'ai construit ma "tiny house", 14 m2 sur roues. Je gagne du temps et de l'argent. Laëtitia Dupé devant sa "tiny house" (DR).

Designer de formation, je me suis lancée un défi un peu fou : réaliser une des toutes premières "tiny houses" de France. Une "tiny house" est une "toute petite maison" la plupart du temps sur roues. Il s'agit d'un logement de plus en plus répandu aux États-Unis, mais encore peu connu dans notre pays. J’ai appelé ce projet "Baluchon", car mon nouveau logement est petit, qu’il ne contient que l’essentiel et que je peux l’emmener partout avec moi. DIY: Glass Bottle Cutter.

ShopBot 101. Handibot™: A Smart Digital Power Tool by ShopBot Tools. A Handibot tool is a new kind of portable, digitally-controlled power tool for cutting, drilling, carving, and many other machining operations– a first Universal Digital Power Tool (UDPT) – or just, a Smart Tool. If you're familiar with industrial CNC (computer numerically controlled) equipment, think of the Handibot tool as a portable version of CNC. But instead of taking material to a stationary machine, you bring the Handibot to your material -- your jobsite, your remodeling task, your project, your work.
