HxC SD: Mounting a tiny LCD and slimming it down
Hey my friends.
Since a really long time (long before HxC Rev.F and Slim Edition), I wanted to take my Rev.C HxC SD Floppy emulator and slim it down as much as possible in order to make it moddable for my taste :)
The one thing I didn't like much was the big (lol) LCD screen that occupied a lot of space.
While searching the bay, I managed to get a really Tiny 16x2 LCD Screen that was really nice for my needs but instead of having pins, it had a ribbon as it's meant for embedded projects.
I don't mind though, as I also got a connector to wire it.
As you can see from the picture below... the size difference is definitely noticeable compared with the default 16x2 LCD screen of HxC SD :)
In order to use this LCD screen, I needed to short 2 of the opened jumper locations as I saw from the online datasheet.
After carefully wiring the connector for the ribbon... SUCCESS I had :)
As I said before, I wanted to slim the HxC SD down so I decided to unsolder the PIC and IC sockets in order to gain some height space. It was a really boring procedure but nothing one man can't do with a bit o patience :)
Since I'm not the best in unsoldering with the El'Cheapo desoldering pump that I own, I managed to loose connection from 3 lines, which after a continuity test, managed to find from nearby lines so no problem at that! (Thank God to my 1st Rev.B to Rev.C HxC SD which helped me find the missing tracks.)
After unsoldering the LCD Header (after my successfull experiment) I soldered the wires from the tiny LCD connector directly to HxC and also hotglued a tiny pcb juts to hold the wires together not to get cut.
I also unsoldered the Drive selection jumpers and short the pins where a jumper for assigne DF0 would have been :)
You can see here the cable connection and the unsoldered PIC and IC :)
Ok, I was happy with the result, but more stuff needed to get out of the way to gain some height space as well. Obstacles were:
- The 34pin floppy connector
- The mini buzzer
- The LCD contrast trimmer
- The 3x PCB mounted buttons
- The molex floppy power connector
- Playing Hybris using Kickstart 1.3 + Disabled ACA
- Loading WB using Kickstart 3.1 + Enabled ACA
