In the last installment of the blog, I was trying to interface a bluetooth dongle with my WS2811 LEDS. This is in support of my long range goal of solar powered deck tread lighting. I hooked up an HM-05\/linvor module to my avr\/dice board, and quickly found out that it didn&#8217;t:<\/p>\n<ol>\n<li>play with my android tablet, or<\/li>\n<li>work with my iPhone.<\/li>\n<\/ol>\n<p>The iPhone control really is the goal here, so I got a few HM-10 modules to play with. These should work, they are bluetooth low energy. So the next problem was that my avr\/LEDs run at 5V and the module is at 3.3. Since I do everything the hard way, I decided to build my own breakout board. I was in a hurry, and made my own by isolation routing a blank pcb.<\/p>\n<ul>\n<ul>\n<li>I whipped up a schematic in protel:<\/li>\n<\/ul>\n<\/ul>\n<p><a href=\"http:\/\/zethus.ca\/wp\/?attachment_id=572\" rel=\"attachment wp-att-572\"><img loading=\"lazy\" class=\"size-medium wp-image-572 alignnone\" src=\"http:\/\/zethus.ca\/wp\/wp-content\/uploads\/2014\/08\/HM10sch-300x188.png\" alt=\"HM10sch\" width=\"300\" height=\"188\" srcset=\"http:\/\/zethus.ca\/wp\/wp-content\/uploads\/2014\/08\/HM10sch-300x188.png 300w, http:\/\/zethus.ca\/wp\/wp-content\/uploads\/2014\/08\/HM10sch.png 871w\" sizes=\"(max-width: 300px) 100vw, 300px\" \/><\/a><\/p>\n<ul>\n<ul>\n<li>Did the board layout:<\/li>\n<\/ul>\n<\/ul>\n<p><a href=\"http:\/\/zethus.ca\/wp\/?attachment_id=570\" rel=\"attachment wp-att-570\"><img loading=\"lazy\" class=\"size-medium wp-image-570 alignnone\" src=\"http:\/\/zethus.ca\/wp\/wp-content\/uploads\/2014\/08\/outp0_original_front-300x291.png\" alt=\"outp0_original_front\" width=\"300\" height=\"291\" srcset=\"http:\/\/zethus.ca\/wp\/wp-content\/uploads\/2014\/08\/outp0_original_front-300x291.png 300w, http:\/\/zethus.ca\/wp\/wp-content\/uploads\/2014\/08\/outp0_original_front-1024x996.png 1024w, http:\/\/zethus.ca\/wp\/wp-content\/uploads\/2014\/08\/outp0_original_front.png 1346w\" sizes=\"(max-width: 300px) 100vw, 300px\" \/><\/a><\/p>\n<ul>\n<ul>\n<li>Converted to voronai mapping with pcb2gcode:<\/li>\n<\/ul>\n<\/ul>\n<p><a href=\"http:\/\/zethus.ca\/wp\/?attachment_id=569\" rel=\"attachment wp-att-569\"><img loading=\"lazy\" class=\"size-medium wp-image-569 alignnone\" src=\"http:\/\/zethus.ca\/wp\/wp-content\/uploads\/2014\/08\/outp1_traced-300x291.png\" alt=\"outp1_traced\" width=\"300\" height=\"291\" srcset=\"http:\/\/zethus.ca\/wp\/wp-content\/uploads\/2014\/08\/outp1_traced-300x291.png 300w, http:\/\/zethus.ca\/wp\/wp-content\/uploads\/2014\/08\/outp1_traced-1024x996.png 1024w, http:\/\/zethus.ca\/wp\/wp-content\/uploads\/2014\/08\/outp1_traced.png 1346w\" sizes=\"(max-width: 300px) 100vw, 300px\" \/><\/a><\/p>\n<ul>\n<ul>\n<li>And routed the sucker:<\/li>\n<\/ul>\n<\/ul>\n<p><a href=\"http:\/\/zethus.ca\/wp\/?attachment_id=567\" rel=\"attachment wp-att-567\"><img loading=\"lazy\" class=\"size-medium wp-image-567 alignnone\" src=\"http:\/\/zethus.ca\/wp\/wp-content\/uploads\/2014\/08\/IMG_2762-300x225.jpg\" alt=\"IMG_2762\" width=\"300\" height=\"225\" srcset=\"http:\/\/zethus.ca\/wp\/wp-content\/uploads\/2014\/08\/IMG_2762-300x225.jpg 300w, http:\/\/zethus.ca\/wp\/wp-content\/uploads\/2014\/08\/IMG_2762-1024x768.jpg 1024w\" sizes=\"(max-width: 300px) 100vw, 300px\" \/><\/a><\/p>\n<ul>\n<ul>\n<ul>\n<li>Then soldered on the parts:<\/li>\n<\/ul>\n<\/ul>\n<\/ul>\n<p><a href=\"http:\/\/zethus.ca\/wp\/?attachment_id=568\" rel=\"attachment wp-att-568\"><img loading=\"lazy\" class=\"size-medium wp-image-568 alignnone\" src=\"http:\/\/zethus.ca\/wp\/wp-content\/uploads\/2014\/08\/IMG_1103-300x225.jpg\" alt=\"IMG_1103\" width=\"300\" height=\"225\" srcset=\"http:\/\/zethus.ca\/wp\/wp-content\/uploads\/2014\/08\/IMG_1103-300x225.jpg 300w, http:\/\/zethus.ca\/wp\/wp-content\/uploads\/2014\/08\/IMG_1103-1024x768.jpg 1024w\" sizes=\"(max-width: 300px) 100vw, 300px\" \/><\/a><\/p>\n<p><a href=\"http:\/\/zethus.ca\/wp\/wp-content\/uploads\/2014\/08\/IMG_1478.jpg\"><img class=\"alignnone size-full\" src=\"http:\/\/zethus.ca\/wp\/wp-content\/uploads\/2014\/08\/IMG_1478.jpg\" alt=\"IMG_1478.JPG\" \/><\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Ok.
