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 useful
I 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.
And here are the files for the 5V PSU (tried and tested), that should provide sufficient power for all modules and leds
The 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 course
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
So 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.
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.
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.
