To validate the PCB design before sending the first batch for manufacture I decided to make a home made board. <\/p>\n<p>With great timing <a href=\"http:\/\/www.re-innovation.co.uk\/\">Matt Little<\/a> had just done a PCB workshop at <a href=\"http:\/\/nottinghack.org.uk\/\">Nottingham Hackspace<\/a> so I had good practical experience. Armed with a UV exposure box from the last <a href=\"http:\/\/www.ddrcbootsale.org\/\">DDRC Car Boot Sale<\/a> and a set of parts from Rapid Electronics I went out to make my PCB.<\/p>\n<p>I basically followed the tips from <a href=\"http:\/\/www.electricstuff.co.uk\/pcbs.html\">Mike Harrison&#8217;s guide<\/a>. For etching I used the Seno GS etching system which manages to keep 99.999% of the really nasty stuff in a bag.<\/p>\n<p>I was delighted that attempt number 1 yielded an almost perfect result.<br \/>\n<a href=\"http:\/\/www.flickr.com\/photos\/sharpie777\/5631503841\/\" title=\"Vibrati Punk Console - Home Made PCB by Sharpie777, on Flickr\"><img decoding=\"async\" loading=\"lazy\" src=\"http:\/\/farm6.static.flickr.com\/5227\/5631503841_8e0d8893f6.jpg\" width=\"500\" height=\"216\" alt=\"Vibrati Punk Console - Home Made PCB\"><\/a><\/p>\n<p>I made a second board as a backup, but that was a complete disaster. Once I developed the UV board you could see that the fine lines weren&#8217;t sharp and once I started etching they disappeared all together. Still not 100% sure what the problem was there. Possibly over-exposure to the UV or the mask not being completely flush to the board when it was exposed. Anyway one board was enough so as it was getting late I stopped there.<\/p>\n<p>One thing I would note for future builds &#8211; the &#8220;automatic&#8221; pad size in Eagle is too small for home made boards. Use larger pads than the eagle defaults to make your life easier.<\/p>\n<p>With the board drilled and everything mounted I am delighted to say it worked first time.<br \/>\n<a href=\"http:\/\/www.flickr.com\/photos\/sharpie777\/5643298039\/\" title=\"Vibrati Punk Console Prototype by Sharpie777, on Flickr\"><img decoding=\"async\" loading=\"lazy\" src=\"http:\/\/farm6.static.flickr.com\/5185\/5643298039_24bcc28f07.jpg\" width=\"500\" height=\"375\" alt=\"Vibrati Punk Console Prototype\"><\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p>For most of my projects I either need quite dense PCBs that I get professionally made or I use point to point wiring techniques.
