Peter has sent his newest arduino project that we might find really practical. Probably many of us find ourself in situation when wee need to switch between speakers and headphones while sitting by computer. This leads to messing around tons of wires behind table. So here is a better solution and probably more fun – Arduino based audio switch. He used several components and built simple prototype board that can be connected to Arduino with Ethernet Shield. By sending a single signal to relay audio signal input can be switched between two outputs. Sound really simple indeed. Interesting part is a software which is actually pretty easy to write as there are libraries like webduino that allows to write pretty complex tasks with a few code lines. Of course using Arduino and Ethernet Shield seems to be to expensive tools for such a simple task, but if you have spare lying around and gathering dust – why not. And don’t limit to audio only – relay can switch other things like lights, motors and other that comes to your imagination.
Guys, if you’re looking for a highly accurate Electronic Temperature-controlled relay, but you don’t want to buy it on at the electronic store, then you should have a sneak peek on this 0 to 100 oC Electronic Temperature-controlled Relay.
In present days, there is many type of headphone amp kits available on the market. However, majority of them are not as good as they’ve claimed. In fact, they’re costing up to hundreds of dollars and consuming a lot of energy!
For those who want to try out something cheaper and energy saving headphone amp kit, maybe you should have a look on the JAN6418 Valve Preamplifier.
For all the home hobbyists, if you lack of time in the weekend, but you just don’t want to miss the fun moment getting yourself busy with the electronics, then you have to check out this CIR-II project!
How much do you think you are familiar with the history of video games? Ok, let’s the trivia game starting…
Question No.1: What is the official name for the earliest arcade video games? Bingo, you’re right! The correct answer is PONG.
Question No.2: When was the PONG game being released? Yep, right on. The answer is 1972!
When someone tells you that you can draw your favorite music by simply using a pencil, would you consider that person a nuts? Honestly, it’s very hard to convince the public that we can actually drawing the music with only a 2B pencil! However, nothing is impossible, especially in this bizarre 21st century, where many wacky-doo stuffs available in the market. Well, thanks to the Drawdio, the magical tool that turns your ordinary pencil into a music drawer. Some of you here must be wondering, “How Drawdio got its name?” Actually, Drawdio is the combination words of “Draw + Audio”. It cuts away the ‘Au’ part, and combined it became “Drawdio”! To be honest, it’s one of the most amazing devices that being invented in the early 21st century. For your information, it’s definitely a great tool, especially for the beginners. There are many possibilities can be created by using the Drawdio. Drawdio is a very simple musical synthesizer. It uses the conductive properties of pencil graphite to create different sound effects. A single AAA battery can operate the Drawdio for many hours, even the “nearly dead” batteries will work fined with the tool. In this case, you can use…
