The LED strip had no drivin circuit on it an the forward voltage was below 5 V. So a modification from 12 V to 5 V was by changing the current limitting resistor easy. To connect the batteries to the circuit I used the Reed Relais and the Magnet. The Magnet is attached in the mailbox inner top using adhesive. The Reed Relais ist mounted on the flap by adhesive as well. Pulling the flap upwards activates the light an let you check for post in the dark :-).<\/p>\n<div id='gallery-2' class='gallery galleryid-572 gallery-columns-3 gallery-size-thumbnail'><figure class='gallery-item'>\n\t\t\t<div class='gallery-icon landscape'>\n\t\t\t\t<a href='http:\/\/www.launet.ch\/blog\/wp-content\/uploads\/2016\/10\/MailboxLight6.jpg'><img loading=\"lazy\" decoding=\"async\" width=\"150\" height=\"150\" src=\"http:\/\/www.launet.ch\/blog\/wp-content\/uploads\/2016\/10\/MailboxLight6-150x150.jpg\" class=\"attachment-thumbnail size-thumbnail\" alt=\"\" aria-describedby=\"gallery-2-571\" \/><\/a>\n\t\t\t<\/div>\n\t\t\t\t<figcaption class='wp-caption-text gallery-caption' id='gallery-2-571'>\n\t\t\t\tSchematics of the installation\n\t\t\t\t<\/figcaption><\/figure><figure class='gallery-item'>\n\t\t\t<div class='gallery-icon landscape'>\n\t\t\t\t<a href='http:\/\/www.launet.ch\/blog\/wp-content\/uploads\/2016\/10\/MailBoxLight1.jpg'><img loading=\"lazy\" decoding=\"async\" width=\"150\" height=\"150\" src=\"http:\/\/www.launet.ch\/blog\/wp-content\/uploads\/2016\/10\/MailBoxLight1-150x150.jpg\" class=\"attachment-thumbnail size-thumbnail\" alt=\"\" aria-describedby=\"gallery-2-564\" \/><\/a>\n\t\t\t<\/div>\n\t\t\t\t<figcaption class='wp-caption-text gallery-caption' id='gallery-2-564'>\n\t\t\t\tLED strip connected to the Booster Circuit\n\t\t\t\t<\/figcaption><\/figure><figure class='gallery-item'>\n\t\t\t<div class='gallery-icon landscape'>\n\t\t\t\t<a href='http:\/\/www.launet.ch\/blog\/wp-content\/uploads\/2016\/10\/MailBoxLight2.jpg'><img loading=\"lazy\" decoding=\"async\" width=\"150\" height=\"150\" src=\"http:\/\/www.launet.ch\/blog\/wp-content\/uploads\/2016\/10\/MailBoxLight2-150x150.jpg\" class=\"attachment-thumbnail size-thumbnail\" alt=\"\" aria-describedby=\"gallery-2-565\" \/><\/a>\n\t\t\t<\/div>\n\t\t\t\t<figcaption class='wp-caption-text gallery-caption' id='gallery-2-565'>\n\t\t\t\tBack of the LED strip: The ugly mod to use the 12 V strip with 5 V\n\t\t\t\t<\/figcaption><\/figure><figure class='gallery-item'>\n\t\t\t<div class='gallery-icon landscape'>\n\t\t\t\t<a href='http:\/\/www.launet.ch\/blog\/wp-content\/uploads\/2016\/10\/MailBoxLight3.jpg'><img loading=\"lazy\" decoding=\"async\" width=\"150\" height=\"150\" src=\"http:\/\/www.launet.ch\/blog\/wp-content\/uploads\/2016\/10\/MailBoxLight3-150x150.jpg\" class=\"attachment-thumbnail size-thumbnail\" alt=\"\" aria-describedby=\"gallery-2-566\" \/><\/a>\n\t\t\t<\/div>\n\t\t\t\t<figcaption class='wp-caption-text gallery-caption' id='gallery-2-566'>\n\t\t\t\tEntire setup wired up: The cable on the top holds the Reed Relais\n\t\t\t\t<\/figcaption><\/figure><figure class='gallery-item'>\n\t\t\t<div class='gallery-icon landscape'>\n\t\t\t\t<a href='http:\/\/www.launet.ch\/blog\/wp-content\/uploads\/2016\/10\/MailBoxLight4.jpg'><img loading=\"lazy\" decoding=\"async\" width=\"150\" height=\"150\" src=\"http:\/\/www.launet.ch\/blog\/wp-content\/uploads\/2016\/10\/MailBoxLight4-150x150.jpg\" class=\"attachment-thumbnail size-thumbnail\" alt=\"\" aria-describedby=\"gallery-2-567\" \/><\/a>\n\t\t\t<\/div>\n\t\t\t\t<figcaption class='wp-caption-text gallery-caption' id='gallery-2-567'>\n\t\t\t\tSwitched on using a Magnet salvaged from an old HDD\n\t\t\t\t<\/figcaption><\/figure><figure class='gallery-item'>\n\t\t\t<div class='gallery-icon landscape'>\n\t\t\t\t<a href='http:\/\/www.launet.ch\/blog\/wp-content\/uploads\/2016\/10\/MailBoxLight5.jpg'><img loading=\"lazy\" decoding=\"async\" width=\"150\" height=\"150\" src=\"http:\/\/www.launet.ch\/blog\/wp-content\/uploads\/2016\/10\/MailBoxLight5-150x150.jpg\" class=\"attachment-thumbnail size-thumbnail\" alt=\"\" aria-describedby=\"gallery-2-570\" \/><\/a>\n\t\t\t<\/div>\n\t\t\t\t<figcaption class='wp-caption-text gallery-caption' id='gallery-2-570'>\n\t\t\t\tThere is post in the mailbox \ud83d\ude42\n\t\t\t\t<\/figcaption><\/figure>\n\t\t<\/div>\n\n","protected":false},"excerpt":{"rendered":"<p>Except from luggage trunks there are other compartments wich are quite dim: Mailboxes.
