Today I want to show you how to make a music receiver that can be easily controlled from your phone.<\/p>\n<p>I know several inexpensive ways to do this: a Bluetooth receiver, an Android HDMI stick, or my favorite \u2013 a Chromecast.<\/p>\n<p><!--more--><\/p>\n<p>The first method is the easiest and allows you to send music from your phone to an amplifier connected to a speaker. The advantage is that it\u2019s very simple\u2026 the downside is that there tends to be cuts in playback. If you\u2019re interested, you can check out <a href=\"http:\/\/www.amazon.com\/HomeSpot-NFC-Enabled-Bluetooth-Receiver-System\/dp\/B009OBCAW2\/ref=sr_1_1?s=electronics&amp;ie=UTF8&amp;qid=1422826222&amp;sr=1-1&amp;keywords=bluetooth+audio+receiver\">this type of product<\/a>.<\/p>\n<p>The second method uses an Android HDMI stick. You can install an app called XBMC (now called Kodi) on these devices. It\u2019s a media center that can connect via Wi-Fi to your computer\u2019s music library or wired to a USB drive. It can also be controlled from your phone with several apps available on the Google Play Store. It\u2019s a very good solution, but the downside is complicated setup\u2026 you have to share your PC folder, assign a static IP to the device running XBMC, link the phone app, and other complications\u2026 not to mention actually installing XBMC on the device. But if you\u2019re interested in trying it, you can download it for your PC at <a href=\"http:\/\/kodi.tv\/\">http:\/\/kodi.tv\/<\/a>. I\u2019ll possibly cover this app in another article later.<\/p>\n<p>But as the wise proverb says, third time\u2019s the charm, and my favorite method is using a Google Chromecast. Now the question is: What is a Chromecast? This device is a bit larger than a USB drive, connects to an HDMI port, and is controlled via mobile apps or websites like Netflix, Deezer, Spotify, or Plex (Plex deserves another article later, but it would allow you to send videos from your PC). All of this uses your Wi-Fi network.<\/p>\n<p><strong>What Do We Need?<\/strong><br \/>\nBasically, the idea is to use Deezer or Google Music to send music to the Chromecast. For this we will need:<\/p>\n<ul>\n<li>Obviously a Chromecast: 35 USD or $33,990 (<a href=\"https:\/\/www.bip.cl\/ecommerce\/index_2.php?modulo=busca&amp;id_producto=15535\">bip.cl<\/a>).<\/li>\n<li>An HDMI audio extractor, the cheapest on Amazon is <a href=\"http:\/\/www.amazon.com\/Optimal-Shop-Female-Adapter-Converter\/dp\/B01ADA5V32\/ref=sr_1_11?s=electronics&amp;ie=UTF8&amp;qid=1422284636&amp;sr=1-11&amp;keywords=hdmi+audio+extractor&amp;th=1&amp;psc=1\">this one<\/a>, costing 10 dollars. (Some TVs have this built in.)<\/li>\n<li>A phone connected to the same Wi-Fi network as the Chromecast.<\/li>\n<li>An audio system with a 3.5mm input \u2013 basically speakers that can connect to the phone; the investment size depends on your preference.<\/li>\n<\/ul>\n<p><strong>Steps<\/strong><\/p>\n<ol>\n<li>Connect the Chromecast to the Wi-Fi network. This must be done with the Chromecast connected to a screen or TV with an HDMI input. You configure it by installing the app for PC or phone (available on Android and iPhone) and can be obtained from <a href=\"https:\/\/cast.google.com\/chromecast\/setup\/\">Google\u2019s site<\/a>.<\/li>\n<li>Once the Chromecast is configured for the Wi-Fi network, connect it to the audio extractor and connect the speakers to the device\u2019s audio output. (A monitor is not necessary now.)<\/li>\n<li>Install Google Music on your phone or use it from your PC via its <a href=\"https:\/\/play.google.com\/music\/listen?u=0#\/now\">website<\/a>. Make sure you are connected to the same Wi-Fi network as the Chromecast.<\/li>\n<li>Connect to the Chromecast using the icon: <img data-recalc-dims=\"1\" height=\"298\" width=\"300\" decoding=\"async\" src=\"https:\/\/i0.wp.com\/www.geekosas.com\/wp-content\/uploads\/2015\/01\/descarga-300x298.png?resize=300%2C298\" alt=\"icon\" \/><\/li>\n<li>Enjoy like I am doing right now.<\/li>\n<\/ol>\n<p><strong>Update<\/strong><br \/>\nNow there is the Chromecast Audio, which does everything in this article in a single device:<br \/>\n<img data-recalc-dims=\"1\" height=\"280\" width=\"300\" decoding=\"async\" src=\"https:\/\/i0.wp.com\/www.geekosas.com\/wp-content\/uploads\/2015\/02\/buy-audio-chromecast-lightbox-300x280.png?resize=300%2C280\" alt=\"Chromecast Audio\" \/><\/p>\n","protected":false},"excerpt":{"rendered":"<div class=\"mh-excerpt\"><p>The purpose of this blog has always been to teach about my various geek inventions, gadgets I buy, tricks to get the most out of <a class=\"mh-excerpt-more\" href=\"https:\/\/geekosas.com\/index.php\/2015\/04\/23\/wireless-music-receiver\/\" title=\"Wireless Music Receiver\">[&#8230;]<\/a><\/p>\n<\/div>","protected":false},"author":1,"featured_media":69,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"_jetpack_newsletter_access":"","_jetpack_dont_email_post_to_subs":false,"_jetpack_newsletter_tier_id":0,"_jetpack_memberships_contains_paywalled_content":false,"_jetpack_memberships_contains_paid_content":false,"footnotes":"","jetpack_publicize_message":"","jetpack_publicize_feature_enabled":true,"jetpack_social_post_already_shared":true,"jetpack_social_options":{"image_generator_settings":{"template":"highway","default_image_id":0,"font":"","enabled":false},"version":2},"jetpack_post_was_ever_published":false},"categories":[1],"tags":[],"class_list":["post-3252","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-sin-categoria"],"jetpack_publicize_connections":[],"jetpack_featured_media_url":"https:\/\/i0.wp.com\/geekosas.com\/wp-content\/uploads\/2015\/01\/descarga.png?fit=323%2C321&ssl=1","jetpack_sharing_enabled":true,"jetpack_shortlink":"https:\/\/wp.me\/p8vjqF-Qs","jetpack-related-posts":[{"id":3264,"url":"https:\/\/geekosas.com\/index.php\/2016\/05\/23\/how-to-choose-a-cell-phone\/","url_meta":{"origin":3252,"position":0},"title":"How to choose a cell phone?","author":"Daniel Fischer","date":"2016-05-23","format":false,"excerpt":"We spend more time with our cell phone than with our family.
