Electronics - www.vetco.net Hobby Engineering Home Page PCB Order | DorkbotPDX Instead of a weekly order, 2 layer circuit boards are now sent to the fab when the panel fills up. This means panels are going out 2 to 3 times a week instead of just once a week. Contents New ordering website! OSH Park! 4 layer orders are now every two weeks. I'm planning another beta 2-layer medium-run order on April 1st, 2013 for people that want at least 150 square inches of their boards. Order Status Keep up to date on the order status updates and to be notified of when the next order will go out: What is this? I've been coordinating a group circuit board order. It's $5 per square inch for three copies of your two layer design. Your two layer boards will be shipped within about 14 days of the order date. For four layer designs, it's $10 for three copies. Four layer boards will be mailed within 16 days. Who's eligible Although this was started primarily for the DorkbotPDX community, it's open to any hobbyist anywhere. Your order helps us continue doing it! What you get The Costs Help! Enjoy!
WiTricity WiTricity is an American engineering company that manufactures devices for wireless energy transfer using resonant energy transfer (oscillating magnetic fields). History[edit] The term WiTricity was used for a project that took place at MIT, led by Marin Soljačić in 2007.[1][2] The MIT researchers successfully demonstrated the ability to power a 60 watt light bulb wirelessly, using two 5-turn copper coils of 60 cm (24 in) diameter, that were 2 m (7 ft) away, at roughly 45% efficiency.[3] The coils were designed to resonate together at 9.9 MHz (≈ wavelength 30 m) and were oriented along the same axis. One was connected inductively to a power source, and the other one to a bulb. The setup powered the bulb on, even when the direct line of sight was blocked using a wooden panel. Automobile manufacturer Toyota made an investment in WiTricity in April 2011.[6][7] Technology[edit] Radiation levels[edit] See also[edit] References[edit] Reference articles[edit] External links[edit]
Liquidware : Open Source Electronics 10 Best Electronics Suppliers First off, I would like to give notice to Electronics Projects for Dummies for most of this info. I wanted to make a site with many of the best sites to buy Electrical Parts, because it can sometimes be a strenuous activity. I have 10 here, because if you can't find something on one online store, you might be able to find it on the next. Reynolds ElectronicsReynolds Electronics is a good supplier of remote control components, micro controllers, and robot kits and parts. Hobby EngineeringHobby Engineering is a sit slanted towards the hobbyist. All ElectronicsAll Electronics has an incredible selection of many of the useful items you would use to build your project. BG MicroBG Micro is a cool site for rare and pretty neat gadgets as well as a nice selection of alot of the items one will need for a weekend project. Jameco ElectronicsJameco has a very nice site catalog. Mouser ElectronicsMouser ElectronicsAnother large distributor of components from various manufacturers is Mouser.
Wireless Power A few years ago MIT created a system for transferring power wirelessly. They transmitted power over a two-meter distance, from the coil on the left to the coil on the right, where it powers a 60W light bulb. Back in 2006, this was a pretty cool thing. Inductive Coupling uses magnetic fields to transfer power. In my research I found, that to transfer power in very complicated. It all starts with the transmitter. The secondary coil has a 0.02 uF capacitor. The primary coil creates a magnetic field, when another coil is placed near it, energy will be induced into it. Be in mind that i could not get a hold of a 0.02uF capacitor so i used two 0.01uF capacitors connected together.
