Please check regularly for stock.<\/p>\n<hr>\n<p>While working on the MMieC project another came to my attention, together with Jussi (who did the hard work) a new smaller PCB was developed off the back of all the projects to create a tiny DTV targetted MMC reader.<br \/>\nThe <a href=\"http:\/\/jderogee.tripod.com\/project1541.htm\">1541-III<\/a> project by Jan Derogee was the most complete project from which Jussi took the source code. My MMieC was the smallest, and the basic design\/idea was taken from that to create hardware that could run Jan\u2019s code on a simple hardware interface.<\/p>\n<p>Credits go to,<br \/>\n<a href=\"http:\/\/jderogee.tripod.com\/\">Jan Derogee<\/a> \u2013 for all his work on the 1541-III without which I doubt this could have happened, the IEC protocol is horrible but Jan did wonders with his source. Jussi Saily \u2013 For redesigning the PCB layout and fixing the source to fit the new hardware. He put a lot of effort into this and again, without him this wouldnt have been possible.<\/p>\n<p>UPDATE 4\/10\/2006 \u2013<br \/>\nJan has incorperated detection of boards into his design. There is now no need for me to supply seperate firmware images. Please visit <a href=\"http:\/\/jderogee.tripod.com\/project1541.htm\">Jan\u2019s site<\/a> for more information on firmware.<\/p>\n<p>UPDATE 1\/10\/2006 \u2013<br \/>\nFollowing feedback on the units and design discusion we are improving the design. Jan is working on some firmware improvements and we are incorperating this into the next batch. Also we have corrected a couple of issues discovered from user feedback with the layout of the board.<br \/>\nPlease thank Jussi for all his work doing the board layout!<\/p>\n<p>UPDATE 25\/09\/2006 \u2013<br \/>\nOk, the new profesional PCB has been made, the firmware has been updated and we are now selling full kits and assembled units on the purchase page. You can still make your own using the instructions below, but a full kit with PCB and assembled units can be purchased instead.<\/p>\n<p><script type=\"text\/javascript\"><!--\ngoogle_ad_client = \"pub-4526948230635423\";\n\/* 300x250, created 4\/15\/09 *\/\ngoogle_ad_slot = \"4264399593\";\ngoogle_ad_width = 300;\ngoogle_ad_height = 250;\n\/\/-->\n<\/script><br \/>\n<script type=\"text\/javascript\"\nsrc=\"http:\/\/pagead2.googlesyndication.com\/pagead\/show_ads.js\">\n<\/script><\/p>\n<p class=\"para\">Anyway, the final project is here..<br \/>\n<a href=\"http:\/\/www.pyrofersprojects.com\/15413\/new-1541-III.hex\">Firmware Update \u2013 Updated firmware .hex with bugfixes by Jan<\/a><br \/>\n<a href=\"http:\/\/www.pyrofersprojects.com\/15413\/1541-III_v11.hex\">Firmware (original) \u2013 Just the .hex file for pic programming<\/a><br \/>\n<a href=\"http:\/\/www.pyrofersprojects.com\/15413\/DTV_1541-III_v1.pdf\">Schematic \u2013 PDF version of the design<\/a><br \/>\n<a href=\"http:\/\/www.pyrofersprojects.com\/15413\/DTV_1541-III_v1.jpg\">PCB and Jumper wires \u2013 JPG of the PCB for wire placement<\/a><br \/>\n<a href=\"http:\/\/www.pyrofersprojects.com\/15413\/DTV-1541-III_v1.zip\">Complete archive \u2013 ALL pcb design items in Gerber format for building your own from scratch<\/a><br \/>\n<a href=\"http:\/\/www.pyrofersprojects.com\/15413\/DTV_1541-III_v11.pdf\">Batch 1 Schematic \u2013 PDF for Original Batch<\/a><br \/>\n<a href=\"http:\/\/www.pyrofersprojects.com\/15413\/DTV_1541-III_v12.pdf\">Batch 2 Schematic \u2013 PDF for 2nd revision PCB<\/a><br \/>\n<a href=\"http:\/\/www.pyrofersprojects.com\/15413\/DTV_1541-III_v13.pdf\">Batch 3 Schematic \u2013 PDF for Final 3rd revision PCB<\/a><\/p>\n<p><a href=\"http:\/\/www.pyrofersprojects.com\/15413\/pcb.zip\">Batch 3 PCB Files \u2013 Final revision of PCB layout<\/a><\/p>\n<p class=\"para\">The main PCB is a single layer board with a dozen or so jumper wires to solder.
