Ethan Winer's Basic Music Theory Videos




Ethan Winer put together a new set of videos explaining basic music theory. These are geared towards the musician and audiophile. This video packs a college-level course into about 2-1/2 hours using detailed explanations and familiar musical examples. However, it includes more than just music theory, such as showing playing techniques for musical instruments, plus a segment about orchestra conductors. Because of the length the video is divided into five segments. Full information is in the description for the first video in the list. Below is the first video, and a link to all 5 videos. Excellent material as usual. Check out all of Ethan's videos for interesting and educational subjects.

Electronics Workbench Laboatory


I don't know what took so long. Maybe building cables on the concrete floor, taking laptops apart on the kitchen granite or building a Linkwitz Transform equalizer on the coffee table. What kind of electronics fanatic does not have a decent workbench? I set about to change this situation. Most of the materials I already had in stock and were recycled from other projects. Its a mix of warped 2x4s, 4x4s, Chinese Birch, Baltic Birch, screws and PL Premium adhesive. I don't have much equipment yet, but I have the basics. A good Weller soldering iron, Fluke Multimeter, 40v 5amp variable power supply, Tektronix 2465ACT Oscilliscope. A place to put my books, a computer, ect. The backbone of my home network sits on top. A pair of 8 port gigabit switches, a TP-Link router running DD-WRT, Linksys cable modem, Silicone Dust ATSC network tuner, and a Synology 211 NAS. To the immediate right of the bench is the back of my audio rack. There is even a Kenwood 599 Amateur Radio transmitter and receiver to play with. It is a work in progress, but I'm happy I finally have a start and a place to sit down and work on things.
