Lorcan Posted June 2, 2009 Report Share Posted June 2, 2009 Hi all,I'm currently building my own LC, and in the process, I wanted to modify the PCBs provided by Thorsten to accommodate for the connectors I bought and other things, so I provide them to the community. Maybe others will find this usefulI have also entered the schematics in Eagle to make it easier, this should prove useful to people designing custom combinations of modules.Here is the DIN x4, DOUT x4, and a 5V/3A linear PSU i made for the LC.Connectors are the 'PSK 254' crimp-connector series from Reichelt.The Core, MF module, and 9V PSU will followCheers,LorcanDIN - DOUT Schematic & Board.rarDIN - DOUT Schematic & Board.rar Quote Link to comment Share on other sites More sharing options...
Lorcan Posted June 2, 2009 Author Report Share Posted June 2, 2009 And here are the files for the 5V PSU (tried and tested), that should provide sufficient power for all modules and ledsThe transfo is a Block EI 66/23 109 from reichelt (9V@4A), and the regulator is a 78t05 which is a version of the 7805 that can handle 3amps, with a proper heatsink of courseMidiBox 5V 3A PSU.rarMidiBox 5V 3A PSU.rar Quote Link to comment Share on other sites More sharing options...
nILS Posted June 2, 2009 Report Share Posted June 2, 2009 Nice work, Lorcan! Thanks for sharing! Quote Link to comment Share on other sites More sharing options...
Lorcan Posted June 4, 2009 Author Report Share Posted June 4, 2009 Thanks, I try to take my time and do things well. I sometimes wish it was finished though, so I could go play music and use it :PSo I also did the schematic and a board for the core (8bit PIC, v3), and I was happy to find it seems to work good.Notice the core pcb has been stripped of the power supply section as this is on a separate board to provide more power and facilitate heatsink moutinf.Now onto the DIN/DOUTS, ledrings, vumeters, LTC ...MidiBox 5V 3A PSU.rarMidiBox 5V 3A PSU.rar Quote Link to comment Share on other sites More sharing options...
ssp Posted September 9, 2009 Report Share Posted September 9, 2009 lorcan that little 5v psu assy is great, thanks for sharing the design and schems, i can build one for the current project now ;) Quote Link to comment Share on other sites More sharing options...
Lorcan Posted September 9, 2009 Author Report Share Posted September 9, 2009 The PSU is quite a standard design, but it works well If I were you maybe I'd change the orientation of the heatsink though, with retrospect I think the reg and the capacitor is squeezed in between the trafo and the heatsink which isn't great in terms of air flow. It would be better if there was some free space around the reg and the big cap to let them breathe a little more. Quote Link to comment Share on other sites More sharing options...
ssp Posted September 9, 2009 Report Share Posted September 9, 2009 yes i see what you mean, but its a nice simple psu design and something i wasnt sure on how to make before, but now thanks to your sharing its clearer to me now.it will be handy to have a little 5v supply in a box on my desk to test with, along side my 9v psu.

Coma Posted November 11, 2009 Report Share Posted November 11, 2009 I can't seem to find the Eagle schematics. Were they lost in the forum update or removed by some other reason? Or I'm too dumb and just can't see them? Thanks! Quote Link to comment Share on other sites More sharing options...
Lorcan Posted November 25, 2009 Author Report Share Posted November 25, 2009 (edited) I can't seem to find the Eagle schematics. Were they lost in the forum update or removed by some other reason? Or I'm too dumb and just can't see them? Thanks! They were lost in the process of the forum upgrade it seems. Also there was a minor error that I corrected afterwards on the pcb, so I need to correct the layouts first. I'll put them up at my site and give you the link here when it's done Edit: the schematics are still there in the posts above. I'll still post the corrected version Edited November 25, 2009 by Lorcan Quote Link to comment Share on other sites More sharing options...

I'll wait for those updated versions anyway, really thank you! Quote Link to comment Share on other sites More sharing options...
svenbogaerts Posted February 1, 2010 Report Share Posted February 1, 2010 The attachment which gives me an error is "DIN - DOUT Schematic & Board.rar". The remaining works just fine. I'll wait for those updated versions anyway, really thank you! I'll wait too for the "DIN - DOUT Schematic & Board.rar". Very nice idea by the way! cheers Quote Link to comment Share on other sites More sharing options...
