I think that&#8217;s the appropriate first draft of the schematic for the HMLiberator. All parts are SMT, including the SOT-8 voltage regulator and crystal. I&#8217;m still not sure how the cables running to the Honda Music Link and iPod will be terminated, but for now I&#8217;m thinking that the wires will simply be soldered into the board, then the body of the cable strapped down to the board for strain relief.<\/p>\n<p>The whole board is intended to be considerably smaller than the Honda Music Link itself, capable of being strapped to the HML and sort-of piggyback on it. It will likely be cased in simple shrink-tubing, as being all SMT and low profile this shouldn&#8217;t be difficult to do at all.<\/p>\n<p>The ICSP connector will be a right-angle .100&#8243; connector on the dev board, and just holes on the production ones (if I do any production runs). I figure the right angle connector can be set in the holes and held in place during programming, and any purchaser who has the means to flash it themselves likely has the means to add the ICSP connector itself.<\/p>\n<p>Now, to fix the FIFO problem and lay out the board. (Hopefully I&#8217;ll get both done by the end of the week.)<\/p>\n<p>Oh, and if any of you can see any problems with that design, please let me know.<\/p>\n","protected":false},"excerpt":{"rendered":"","protected":false},"author":2,"featured_media":0,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[6,11,34],"tags":[],"class_list":["post-8745","post","type-post","status-publish","format-standard","hentry","category-electronics","category-making-things","category-moved-from-livejournal"],"_links":{"self":[{"href":"https:\/\/nuxx.net\/blog\/wp-json\/wp\/v2\/posts\/8745","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/nuxx.net\/blog\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/nuxx.net\/blog\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/nuxx.net\/blog\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/nuxx.net\/blog\/wp-json\/wp\/v2\/comments?post=8745"}],"version-history":[{"count":1,"href":"https:\/\/nuxx.net\/blog\/wp-json\/wp\/v2\/posts\/8745\/revisions"}],"predecessor-version":[{"id":12885,"href":"https:\/\/nuxx.net\/blog\/wp-json\/wp\/v2\/posts\/8745\/revisions\/12885"}],"wp:attachment":[{"href":"https:\/\/nuxx.net\/blog\/wp-json\/wp\/v2\/media?parent=8745"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/nuxx.net\/blog\/wp-json\/wp\/v2\/categories?post=8745"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/nuxx.net\/blog\/wp-json\/wp\/v2\/tags?post=8745"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
